Got Questions? Ask the Flu Experts!
How many times can a person become infected with the flu virus ? | ||
A: | You are unlikely to get infected with the same exact strain of influenza (flu) more than once. It's possible for a person to be infected with influenza (flu) virus more than 1 time in a season. This is because several different strains of flu virus circulate (go around) each year. Exposure to a particular strain of flu virus may help protect you against that strain in the future. But, it will not protect you from infection with other flu virus strains. It's important to remember that there are many different types of flu viruses that are constantly changing. This means that antibodies (infection fighting cells) made against 1 strain of flu virus:
Several different types of flu viruses can go around each flu season. The viruses change from flu season to flu season. This year, there was a new H1N1 flu virus circulating in addition to the seasonal flu viruses that normally infect and cause illness in people during the flu season. In addition to flu viruses, several other respiratory viruses also can circulate during the flu season and can cause symptoms and illness similar to those seen with flu infection. These non-flu viruses include rhinovirus (one cause of the "common cold") and respiratory syncytial virus (RSV), which is the most common cause of severe respiratory illness in young children, as well as a leading cause of death from respiratory illness in those aged 65 years and older. | |
If a caregiver is coughing/sneezing, and wears a mask when caring for Clients, how frequently must that basic, surgical mask be changed? | ||
A: | If you have not already done so, we recommend that you contact the Home Care Licensure Division of your state health department for guidance. Here is a link to finding state health departments. Ill healthcare workers should not be involved in patient care, especially those with compromised immune systems. Use of a mask by the healthcare worker would likely not be adequate to prevent possible transmission. For more information about infection control in the home care setting, please visit the CDC Web site: Infection Control in Home Care | |
When should we stop administering the H1N1 and seasonal flu vaccine this year? | ||
A: | The CDC recommends continuing vaccination for the H1N1 flu until the vaccine expires. There is no official date to stop administering (giving) seasonal influenza (flu) vaccines. Each flu season varies, beginning and ending in different months. Providers should continue to administer the flu vaccine in the U.S. as long as flu viruses continue to circulate in this country. | |
If the expiration date on the H1N1 nasal spray states 2/23/10 can it be given that day or is it considered expired that date? | ||
A: | The vaccine or diluent may be used up to and including this date unless otherwise stated in the product package insert. Vaccine and diluent should not be used after this date has passed. When the expiration date is marked with only a month and year, the vaccine or diluent may be used up to and including the last day of the month indicated on the vial. Any unused vaccine or diluent should not be used after this month has passed. More information can be found at: | |
How do scientists determine which strain(s) of flu to create a vaccine for? | ||
A: | The viruses used in making seasonal flu vaccine are chosen each year based on information gathered over the previous year about the strains of flu viruses that are infecting humans and how they are changing. Circulating influenza strains and information on disease trends are gathered by 122 national influenza centers in 94 countries and the viruses and other data are further tested and combined data are analyzed by the four World Health Organization (WHO) Collaborating Centers for Reference and Research on Influenza located at the Centers for Disease Control and Prevention (CDC) in Atlanta; London, United Kingdom; Melbourne, Australia; and Tokyo, Japan. Based on this information, experts forecast which viruses are likely to circulate the following season and WHO recommends specific virus strains that can be used to make vaccines to protect against them. For vaccines being made for the Northern Hemisphere, the recommendation is made by WHO in February each year. For vaccines being made for the Southern Hemisphere, the recommendation is made by WHO in September. Each country then can use the recommendations made by WHO to assist with national decisions about what viruses to use in influenza vaccines for their country. In the U.S., an advisory committee convened by the Food and Drug Administration (FDA) makes the final decision about vaccine strains in February. Manufacturers grow vaccine strains based on these recommendations; but they often begin the production process as early as January based on their assessment of which strains will be chosen for the vaccine.

I am pregnant for just 1 month. Can I take the H1N1 injection? | ||
A: | Pregnant or breastfeeding women can get the inactivated 2009 H1N1 influenza (flu) vaccine (flu shot). Inactivated 2009 H1N1 vaccine may be given at the same time as other vaccines, including the seasonal influenza (flu) vaccine. People who have a severe (life-threatening) allergy to chicken eggs, or to any other substance in the vaccine, should not be vaccinated for 2009 H1N1 influenza (flu). Tell the person giving you the vaccine if you have any severe allergies. If you are concerned about whether or not you should get vaccinated for 2009 H1N1 flu, talk with your doctor. Let your doctor (or the person giving you the vaccine) know if you have ever had:
These may not be reasons to avoid the H1N1 flu vaccine, but your doctor can help you decide. If you are moderately or severely ill, you might be advised to wait until you recover before getting the vaccine. If you have a mild cold or other illness, there is usually no need to wait. | |
How do we clean the hotel room of someone who had the flu? | ||
A: | The influenza (flu) virus can live on hard objects up to 8 hours. Flu viruses may be spread when a person touches a hard surface (such as a desk or doorknob) or an object (such as a keyboard or pen) where the virus has landed and then touches his or her eyes, nose, or mouth. Routine cleaning of surfaces will help stop the virus from spreading in this way. You should clean surfaces and items that are more likely to have frequent hand contact with cleaning agents that are usually used in these areas. There are several chemical cleaning products that can kill flu viruses, including:
These products are effective if the right amount is used for the right period of time. For example, wipes or gels with alcohol in them can be used to clean hands. The gels should be rubbed in until they are dry. Additional disinfection beyond routine cleaning is not recommended. | |
Is it ok for two family members who have the flu to share food, utensils, drinks? | ||
A: | Please note that there is more than one strain of the flu virus, thus, persons with the flu should not be sharing food, utensils and drinks to avoid getting reinfected with a new strain. Persons with the flu should throw away tissues and other disposable items used by them in the trash. They should wash their hands after touching used tissues and similar waste. Keep surfaces (especially bedside tables, surfaces in the bathroom, and toyus for children) clean by wiping them down with a household disinfectant according to directions on theproduct label. Linens, eating utensils, and dishes belonging to those who are sick do not need to be cleaned separately. However, importantly, these items should not be shared without washing throoughly first. Wash linens (such as bed sheets and towels) using household laundry soap and tumble dry on a hot setting. Avoid “hugging” laundry prior to washing it to prevent contaminating yourself. Clean your hands with and water or alcohol-based hand rub right after handling dirty laundry. Wash eating utensils either in a dishwasher or by hand with water and soap. | |
Will there be a different vaccine for H1N1 next year? | ||
A: | The vaccine to protect against the 2009 H1N1 influenza virus will be the same for the entire 2009-2010 influenza season, which extends into the spring of 2010. The "2009" in the name only relates to the year the virus was first identified; it does not have to do with how long the vaccine will work or the year in which it should be administered. The 2009 H1N1 virus is not included in the 2009-2010 seasonal flu vaccine because it was identified after manufacturers had started making the seasonal flu vaccine. The Influenza A (H1N1) 2009 Monovalent vaccines are made from a single influenza virus strain that is an A/California/7/09-like virus. | |
Is it necessary to re-vaccinate someone who was vaccinated with H1N1 vaccine (from multi-dose vial) that had been previously (mistakenly) frozen? | ||
A: | Failure to adhere to recommended specifications for storage and handling of vaccines can reduce their potency, resulting in an inadequate immune response in the recipient. Inactivated H1N1 influenza vaccine should be stored at 35 to 46 degrees Fahrenheit (2 to 8 degrees Celsius) and should not be frozen. Inactivated vaccine that has been frozen should be discarded. See: 2009 H1N1 Monovalent Influenza Vaccine Dosage, Administration, and Storage If the vaccine was given despite being frozen, we recommend that you contact your state health department and the manufacturer of the vaccine for guidance in determining if revaccination is necessary. Contact information for state health departments can be found online at: http://www.cdc.gov/mmwr/international/relres.html | |
When will the H1N1 threat pass? Will it be March 2010? April? Etc.? | ||
A: | Influenza (flu) is unpredictable and the timing, spread, and severity of flu viruses is uncertain. Flu outbreaks may occur in different places at different times. Outbreaks can happen in "waves" of 6- to 8-week time periods. These waves can happen over several months or years. During each wave, different people may be affected. In past pandemics, "waves" of activity have been observed. The first wave is usually a smaller wave and is followed by a larger "peak" wave. Later on smaller waves can occur as well. With 2009 H1N1 influenza (flu), the U.S. experienced its first wave of pandemic activity in the spring of 2009. A second wave of 2009 H1N1 activity followed in the fall, with activity peaking in October. In recent weeks, flu activity has decreased and at this time activity is low. Flu season can last as late as May. So, it's possible that other waves of flu activity may occur this flu season, caused by either 2009 H1N1 viruses or regular seasonal flu viruses. It's also likely that the 2009 H1N1 virus will circulate again next flu season. | |
Will the 2010-2011 seasonal vaccine protect against H1N1? | ||
A: | The decision whether to combine the H1N1 and seasonal flu vaccines as one for the 2010 to 2011 influenza season has not been made final yet. However, this topic will likely be discussed at the Advisory Committee on Immunization Practices (ACIP) meeting scheduled for February 24 and 25, 2010. ACIP meeting minutes are posted to the website within 90 days of the meeting date and can be accessed on the CDC website at: | |
Could you please tell me what the count is on fatalities related to swine flu--H1N1,in the USA? | ||
A: | The most up to date statistics concerning flu fatalities can be found at"CDC Estimates of 2009 H1N1 Influenza Cases, Hospitalizations and Deaths in the United States, April – January 16, 2009" which is updated monthly. Also, see:

If my aunt got H1N1 vaccination, can she still get infected, or is the protection absolute? | ||
A: | When the 'match' between circulating influenza (flu) viruses and the flu vaccine is close, the flu shot prevents the flu in about 70 to 90 percent of healthy people younger than 65 years of age. Some people who get the influenza (flu) vaccine may still get the flu. No vaccine, including the flu vaccine, is 100 percent effective. But, the vaccine can still make the illness less severe and help prevent flu-related complications (health problems). It takes about 2 weeks after you get the vaccine for antibodies (infection-fighting cells) to develop and provide protection. In the meantime, you're still at risk for getting the flu. The ability of the flu vaccine to protect a person depends on:
People can also become sick from other non-flu viruses that are around during the flu season, which can cause flu-like symptoms. | |
If I just finished taking an antibiotic for upper resp. infection, is it ok to get the h1n1 vaccine right away? | ||
A: | Antibiotics (drugs that fight bacterial illness) have no effect on influenza (flu) viruses or flu vaccines. A person taking an antibiotic may get:
However, if the person taking the antibiotic has a moderate or severe acute illness, he or she should wait to get vaccinated until they are no longer ill. | |
If someone has already had the H1N1 Flu, can they get it again? or will they be immune? | ||
A: | You are unlikely to get infected with the same exact strain of flu more than once. Most people with flu-like illness since spring 2009 don't know whether they were infected with 2009 H1N1 or another flu virus strain. The only sure way to diagnose 2009 H1N1 infection is with real-time reverse transcription-polymerase chain reaction (RT-PCR). Even if you had a confirmed case of 2009 H1N1 flu, you can still get infected with other flu strains. You should make sure you get the seasonal flu vaccine. | |
Should H1N1 vaccine be given if a person was suspicious for H1N1 flu infection last November? | ||
A: | People who were infected with the 2009 H1N1 virus and who are not severely immune compromised will likely have immunity to subsequent infection with 2009 H1N1 virus. However, vaccination of a person with some existing immunity to the 2009 H1N1 virus will not be harmful, and patients who are uncertain about how they were diagnosed should get the 2009 H1N1 vaccine. Persons who were not tested, but who became ill after being exposed to a person with lab-confirmed 2009 H1N1 flu, should not assume that they also had 2009 H1N1 as many pathogens can cause a flu-like illness. These people should get the vaccine if they are in a recommended vaccination target group. The 2009 H1N1 virus does not provide protection against seasonal influenza viruses. Therefore, people who get the 2009 H1N1 vaccine should also get a seasonal vaccine. | |
Can I after I play sports after I get my flu shot? | ||
A: | There is no reason to avoid normal activities after getting the influenza vaccine. After getting vaccinated for flu, you can return to normal activities, such as:
Some people may have minor side effects from the flu vaccine. If you have any of these minor side effects, you may want to wait to participate in some activities until you feel better. If you are having a severe or allergic reaction to the vaccine, see your doctor right away. | |
I have already been sick with the seasonal flu; not H1N1. Should I still receive the seasonal flu shot? | ||
A: | It is possible to contract the flu more than once in the same season as there are many different strains circulating during the same season. People can also become sick from other non-flu viruses that are around during the flu season, which can cause flu-like symptoms. A person who is infected with an influenza (flu) virus is likely to have some immunity to closely related flu viruses in the same season or additional seasons. This may provide them with some protection if they are exposed; however, the amount of protection will depend on their health status. Additionally, it is important to remember that there are many different types of flu viruses that are constantly changing. This means that antibodies made against one strain of flu virus:
| |
If I have a head cold (runny nose and sneezing, but NO fever), can I still receive the H1N1 shot? | ||
A: | If you are moderately or severely ill, you might be advised to wait until you recover before getting the H1N1 vaccine. If you have a mild cold or other illness, there is usually no need to wait. If you have further questions, please contact your physician or healthcare provider. He or she is in the best position to offer guidance or otherwise counsel you on a course of action appropriate to your concerns and can help you decide if the H1N1 vaccine is appropriate for you. You may also wish to contact your state health department for guidance. Contact information for the different state health departments can be found online at http://www.cdc.gov/mmwr/international/relres.html | |
What steps should businesses take to prevent a flu outbreak at the worksite? | ||
A: | Businesses and employees should maintain worksite standards as required by your local Public Health Departement. Also, consider adding the following steps if flu conditions become more severe.
Additional information on all these topics is available on Flu.gov. Frequently asked workplace questions can be found at: http://answers.flu.gov/categories/284 | |
My son is due for his 2nd dose of flu mist. He is currently on Nasonex. Is this OK? Also, he was treated with a round of steriod 2 weeks ago for tonsilitis. Any contraindication? | ||
A: | Whether a person taking steroids can get live attenuated (nasal-spray) vaccine (LAIV) depends on the dose and length of steroid therapy. If the dose was 20 mg of prednisone or more per day for 14 or more days, LAIV should be deferred for 1 month after cessation of therapy or reduction of the dose. If the dose was less than 20 mg per day or for less than 14 days, LAIV can be given at any time. | |
When does the flu season end? Can I still get the flu and H1N1 vaccines if I wanted? | ||
A: | There is no official date to stop administering (giving) seasonal influenza (flu) vaccines and/or 2009 H1N1 flu vaccine. Each flu season varies, beginning and ending in different months. In the U.S., the flu season can begin as early as October and can occur as late as May. There is a myth that the flu vaccine doesn't need to be given after Thanksgiving. Flu vaccine given in December, January, or even later can still be effective in preventing the flu. The flu vaccine should continue to be administered in the U.S. as long as flu viruses continue to circulate in this country. To find out where the H1N1 flu shot is being offered in your area, please use the flu shot locator found online at: http://www.flu.gov | |
What occurs when a virus changes and the result makes the antiviral drug less effective in treating it? | ||
A: | Influenza viruses are dynamic and are continuously evolving. Influenza viruses can change in two different ways:
Influenza viruses are changing by antigenic drift all the time. Antigenic shift happens only occasionally. Influenza type A viruses undergo both kinds of changes; influenza type B viruses change only by the more gradual process of antigenic drift. Antigenic drift refers to small, gradual changes that occur through point mutations in the two genes that contain the genetic material to produce the main surface proteins, hemagglutinin, and neuraminidase. These point mutations occur unpredictably and result in minor changes to these surface proteins. Antigenic drift produces new virus strains that may not be recognized by antibodies to earlier influenza strains. This process works as follows: a person infected with a particular influenza virus strain develops antibody against that strain. As newer virus strains appear, the antibodies against the older strains might not recognize the "newer" virus, and infection with a new strain can occur. This is one of the main reasons why people can become infected with influenza viruses more than one time and why global surveillance is critical in order to monitor the evolution of human influenza virus stains for selection of which strains should be included in the annual production of influenza vaccine. In most years, one or two of the three virus strains in the influenza vaccine are updated to keep up with the changes in the circulating influenza viruses. For this reason, people who want to be immunized against influenza need to be vaccinated every year. Antigenic shift refers to an abrupt, major change to produce a novel influenza A virus subtype in humans that was not currently circulating among people (see more information below under Influenza Type A and Its Subtypes). Antigenic shift can occur either through direct animal (poultry)-to-human transmission or through mixing of human influenza A and animal influenza A virus genes to create a new human influenza A subtype virus through a process called genetic reassortment. Antigenic shift results in a new human influenza A subtype. A global influenza pandemic (worldwide spread) may occur if three conditions are met:

How long does it take to have a serious reaction from the seasonal flu vaccine? | ||
A: | Possible side effects usually begin soon after the shot is given and they last 1 to 2 days. Typical side effects include:
If you experience any unusual conditions after being vaccinated, including high fever or behavioral changes, seek medical attention right away. Life-threatening allergic reactions to vaccines are very rare. If they do occur, it is usually within a few minutes to a few hours after the vaccination. Signs of a serious allergic reaction can include:

My daughter came down with the flu several days after getting the H1N1 nasal spray. Can taking Tamiflu interfere with the effectiveness of the vaccine? | ||
A: | If a person is taking an influenza antiviral drug (including Tamiflu or Relenza), the nasal spray flu vaccine should not be given until 48 hours after the last dose of the influenza antiviral medication was given. If a person takes antiviral drugs within two weeks of getting the nasal spray flu vaccine, that person should get revaccinated. (The antiviral drugs will have killed the vaccine viruses that are supposed to cause the immune response against those viruses.) Antiviral drugs can be taken with the inactivated flu vaccines (e.g., seasonal or H1N1). | |
What can I do to make sure my workspace is free of flu and other viruses? | ||
A: | Influenza virus can survive for 24-48 hours or longer on nonporous surfaces and 8-12 hours on porous surfaces such as paper or cloth and can be transmitted to persons’ hands from these surfaces. Flu viruses may be spread when a person touches a hard surface (such as a desk or doorknob) or an object (such as a keyboard or pen) where the virus has landed and then touches his or her eyes, nose, or mouth. Routine cleaning of surfaces will help stop the virus from spreading in this way. | |
I received the inactivated H1N1 vaccine yesterday. How long do I have to wait before I can receive the live shingles vaccine? | ||
A: | The 2009 H1N1 flu shot can be given on the same day as any other vaccine, including seasonal flu shot and pneumococcal polysaccharide vaccine. If given on the same day, the shots should be given in different sites on the body. If desired, they can be given at any interval before or after each other. The 2009 H1N1 nasal spray vaccine which contains a live, but weakened virus can be given at the same time as any other vaccine, except the Seasonal flu spray vaccine. The 2009 H1N1 and seasonal nasal-spray vaccines should be administered at least 4 weeks (28 days) apart. | |
As an employer, can I let my staff know if someone has contracted a contagious disease like the flu? | ||
A: | In general, giving out personal health information is not allowed by law. This law is designed to protect the privacy of all persons in the United States. | |
Where on the body is the best place to get the flu shot? | ||
A: | The intramuscular route is recommended for administering the influenza A (H1N1) 2009 monovalent inactivated vaccine. Adults and older children should be vaccinated in the deltoid muscle. A needle length of 1 inch or longer (25 mm or longer) should be considered for persons in these age groups because needles of less than 1 inch might be of insufficient length to penetrate muscle tissue in certain adults and older children. When injecting into the deltoid muscle in children with adequate deltoid muscle mass, a needle length of 7/8” to 1.25 inches is recommended. Infants and young children should be vaccinated in the anterolateral aspect of the thigh. A needle length of 7/8” to 1 inch should be used for children younger than 12 months of age. | |
Should my kids get vaccinated even if they got clinical flu in early Nov? | ||
A: | You are unlikely to get infected with the same exact strain of influenza (flu) more than once. Most people with flu-like illness since spring 2009 don't know whether they were infected with 2009 H1N1 or another flu virus strain. If you think you had 2009 H1N1 infection, ask your doctor if you should be vaccinated. The only sure way to diagnose 2009 H1N1 infection is with real-time reverse transcription-polymerase chain reaction (RT-PCR) Even if you had a confirmed case of 2009 H1N1 flu, you can still get infected with other flu strains. You should make sure you get the seasonal flu vaccine. If you had a flu-like illness since spring 2009 that wasn't diagnosed as 2009 H1N1 flu by RT-PCR, get the H1N1 and seasonal flu vaccines. | |
Do we need the H1N1 flu shot to enter the USA for a visit? | ||
A: | Vaccination for influenza (2009 H1N1 or seasonal flu) is not required for entry to any country in the world. By international agreement, a country can only require evidence of vaccination against yellow fever. For more information, see Information for Travelers | |
I got the H1N1 vaccine. Am I now immune for life, like a polio vaccine? | ||
A: | The length of time that the H1N1 vaccine will provide protection is not yet known. However, it will likely be 6 to 12 months, like seasonal vaccine. | |
If I have a cold right now. can I get the H1N1 vaccine today? | ||
A: | If you are sick with a fever when you go to get your flu shot, talk to your doctor or nurse about getting your shot at a later date. However, you can get a flu shot if you have a respiratory (breathing) illness without a fever; or if you have another mild illness. If you are moderately or severely ill, you might be advised to wait until you recover before getting the vaccine. If you have a mild cold or other illness, there is usually no need to wait. | |
Where can I find some statistic/numbers comparing the H1N1 flu outbreak with the seasonal flu? | ||
A: | Unfortunately, mortality data that is comparable for seasonal influenza versus H1N1 influenza is not collected because it is impossible to know the total universe of people who get the disease. CDC does not track the disease in every person. However, CDC is tracking all influenza viruses, most of which are the new H1N1. The following may be helpful regarding H1N1-specific mortality and hospitalization from provisional data: The following may also be of interest:
| |
After you take the shots of flu vaccine, it is ok or possible to drink liquor or beer? I'm just curious. | ||
A: | There is no reason to avoid normal activities after getting 2009 H1N1 influenza (flu) vaccine. After getting vaccinated for influenza, you can return to normal activities, such as
Some people may have minor side effects from the flu vaccine. If you have any of these minor side effects, you may want to wait to participate in some activities until you feel better. If you are having a more severe or allergic reaction to the vaccine, go see your doctor right away. Vaccine Side Effect Information: http://answers.flu.gov/questions/4172 | |
I work in the retail business as a sales associate. I handle a lot of money. Can the flu virus live on money and can I get the flu by touching money? | ||
A: | Studies have shown that influenza (flu) viruses can survive on environmental surfaces and can infect a person for up to 2 to 8 hours after being deposited (left) on surfaces like dining area tables, doorknobs, and desks. Frequent handwashing will help you reduce the chance of getting contamination (tainted) from these common surfaces. | |
Is it still true that my 9 year old child can get the nasal H1N1 vaccine even though his 1st vaccination was in the injectable form? Your H1N1 PDF states this, but my pediatrician's Web site says they must be in the same form. | ||
A: | When feasible, the same type of vaccine (live attenuated or inactivated) should be used in a 2-dose schedule, but mixed schedules are preferable to not completing the series. A 28-day interval between doses is recommended, but a 21-day interval is acceptable. | |
What is the dosage for flu vaccine for children? | ||
A: | Please visit the CDC website to view the dosage recommendations for the seasonal influenza vaccination. | |
How many people have died from the regular flu this year compared to those that have died from H1N1 flu this year? | ||
A: | Unfortunately, the CDC is unable to give mortality data that is comparable for seasonal influenza versus H1N1 influenza since it is not possible to know the total universe of people who get each type of disease. CDC is tracking all influenza viruses as a group, and most of these are the new H1N1. Individual case counts were used in the early stages of the outbreak to track the spread of disease. As novel H1N1 flu became more widespread, individual case counts became an increasingly inaccurate representation of the true burden of the disease. This is because many people likely became mildly ill with novel H1N1 flu and never sought treatment; many people may have sought and received treatment, but were never officially tested or diagnosed; and as the outbreak intensified, in some cases, testing was limited to only hospitalized patients. That means that the official case count represented only a fraction of the true burden of novel H1N1 flu illness in the United States. CDC recognized early in the outbreak that once disease was widespread, it would be more valuable to transition to standard surveillance systems to monitor illness, hospitalizations and deaths. | |
How long is a regular flu shot good for? | ||
A: | It takes about 2 weeks after vaccination for antibodies to develop and provide protection. In the meantime, people are still at risk for getting the flu. Flu vaccination provides protection against influenza (flu) strains contained in the vaccine through one flu season. | |
Can a dust mask be considered a facemask when a facemask is recommended to be worn? By definition a facemask is loose-fitting, and creates a physical barrier between mouth and nose of wearer and potential contaminants in the immediate area. | ||
A: | The term "mask" can have many meanings. Most respirators include some kind of face mask, but not all face masks are respirators approved by the National Institute for Occupational Safety and Health (NIOSH). A "mask" can be a thin, cupped paper filter that covers the nose and mouth. Another type of mask is a surgical mask, which is a loose-fitting disposable mask. These are designed to help stop droplets from being spread by the person wearing it. However, they are not designed to protect you from breathing in very small particles. Thin paper masks and surgical face masks are often not NIOSH-approved respirators. If they are NIOSH approved, the word "NIOSH" will appear on the mask, and a NIOSH approval number will appear on the packaging or the user instructions. NIOSH recommends that anyone who needs to wear a respirator wear a NIOSH-approved respirator. Some NIOSH-approved respirators are also commonly referred to as masks. This is because they resemble the thin, cupped paper filters that cover the nose and mouth. One example of these respirators is an N-95 filtering face piece. These are designed to fit tightly to the face so that most air is inhaled (breathed in) through the filter material. These filtering facepiece respirators can be made out of varying combinations of filter material depending on the desired level of filtration and the resistance of the filter to oil. NIOSH-certified respirators will be labeled to indicate that they are NIOSH-certified. Other types of masks that have not been certified by NIOSH should not be used as protection from airborne particulates. Most of the time N95 respirators are used in construction and other jobs that involve dust and small particles. Some healthcare workers, such as nurses and doctors, use these types of respirators when taking care of patients with diseases that can be spread through the air. People with heart or lung disease, or other health condition, may have trouble breathing through respirators. Talk to your doctor before using a respirator. Like surgical masks, N95 respirators should be worn only once and then thrown away in the trash. | |
My child is 10 months old and was administrated the H1N1 vaccine on 11/06/09 and is due for his second administration of the H1N1 vaccine. Unfortunately, his primary physician has run out of vaccinations. I need help locating a clinic, a doctor's office, or a local CVS or Walgreens that are providing the vaccination. | ||
A: | Please continue to work with your child's doctor. State and local public heath departments are responsible for directing the flow of vaccine to providers within every state. They determine which providers receive vaccine and they allocate vaccine among providers as it becomes available to them. If you have not already done so, please contact your state health department for information on 2009 H1N1 vaccine distribution plans. A directory of state health departments is available online at: If you would like to search online for a registered flu vaccination clinic in your area, please visit the Flu Vaccine Locator on http://www.flu.gov/ . | |
I am trying to find the statistic of number of deaths by regular flu yearly. Why is H1N1 marked as pandemic? Again, I am looking for statistics. | ||
A: | The National Vital Statistics System (NVSS) provides the nation's official vital statistics data. Data are based on the collection and registration of birth and death events at the state and local level. The NVSS provides the most complete and continuous data available to public health officials at the national, state, and local levels, and in the private sector. Examples of NVSS data:
You can find the most current vital statistic data on these Web sites:
On June 11, 2009, the World Health Organization (WHO) declared Pandemic Phase 6 for novel H1N1 influenza (flu). Raising the alert level to Pandemic Phase 6 for this outbreak of flu means that the current novel H1N1 flu spreading involves sustained human-to-human transmission (spread) in 2 or more regions of the world. Pandemic Phase 6 is an indicator of spread and not of severity of illness. | |
I am a nurse working on a post op surgical floor. Our othropedic surgeons do not want to give flu shots after surgery. Can you address the pro's and con's for me? | ||
A: | If there are no other contraindications to receiving seasonal or 2009 H1N1 influenza vaccines, then there are no disadvantages to vaccination following orthopedic surgery. Please note that vaccinating a patient increases the chance that the person will be protected from influenza. | |
I keep reading that children under 9 need two doses of the h1n1. But if its not their first vaccine, they only need one. My child has had the regular flu shots before so does he only need one does of the h1n1 or two? | ||
A: | All children 2 through 9 years of age getting a 2009 H1N1 vaccine will need two doses of 2009 H1N1 vaccine (either the 2009 H1N1 flu shot or the 2009 H1N1 nasal spray vaccine). The first dose should being given as soon as vaccine becomes available. The second dose should be given 28 or more days after the first dose. The first dose "primes" the immune system; the second dose provides immune protection. Children who only get one dose of vaccine when they need two doses may have reduced or no protection. Be sure to follow up to get your child a second dose if they need one. It usually takes about two weeks after the second dose for protection to begin. | |
I had a possible reaction to the H1N1 vaccine. Do I need to report it? Within an hour of the shot I felt like I had mono. I was lethargic for over 4 days - all I did was sleep. I was nausiated and dizzy with frequent chills where I just could not get warm. I never had that type of reaction to a flu shot before. | ||
A: | When feasible, the same type of vaccine (live attenuated or inactivated) should be used in a 2-dose schedule, but mixed schedules are preferable to not completing the s After getting vaccinated against the 2009 H1N1 influenza (flu), you should look for any unusual condition, such as a high fever or behavior changes. Signs of a serious allergic reaction can include:
If any unusual condition occurs following vaccination, seek medical attention right away. Tell your doctor what happened, the date and time it happened, and when the vaccination was given. Ask your doctor, nurse, or health department to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS) form. You can file this report yourself through the VAERS Web site. You may call 1-800-822-7967 to receive a copy of the VAERS form. VAERS is not able to provide medical advice. | |
My sons, ages 2 and 4, got the H1N1 mist in November and the clinic is now out of the mist. Is it okay for them to get the second dose of the H1N1 vaccine as a shot or does it need to be the mist since the first dose was the mist? | ||
A: | When feasible, the same type of vaccine (live attenuated or inactivated) should be used in a 2-dose schedule, but mixed schedules are preferable to not completing the series. A 28-day interval between doses is recommended, but 21 days is acceptable. There are limited data on mixed schedules. | |
My 16th month old daughter was mistakenly given the H1N1 nasal spray instead of the shot. Why aren't children under 2 supposed to get the nasal spray and is there any increased danger of side effects because of it? Also, should she now get a series of 2 shots or a 2nd nasal spray to immunize her? | ||
A: | If an individual younger than 2 years is inadvertently given the live-attenuated intranasal (nasal spray) vaccine (LAIV) form of the 2009 H1N1 vaccine, the dose may be counted as valid, even though the minimum labeled age for LAIV is 2 years. The child still needs the second dose of vaccine in 4 weeks. However, the second dose should be the inactivated flu shot, not LAIV spray. If you have additional questions or concerns, please speak with you daughter's primary healthcare provider. He or she can best assist you in this matter. | |
Could you tell me the differences between the H1N1 flu and the bird flu? | ||
A: | 2009 H1N1 flu is a respiratory (breathing tract) disease caused by type A influenza (flu) virus. This is a type of flu virus that spreads from human-to-human, but that originated (came from) from swine. In contrast, the Avian influenza (bird flu) is a disease of birds caused by infection with avian influenza A viruses. There are 3 types of influenza (flu) viruses:
Avian influenza viruses, also known as bird flu viruses, are also influenza A viruses. All known subtypes of influenza A viruses can be found in birds. Influenza A viruses:
The avian influenza virus currently of greatest concern is highly pathogenic avian influenza A (H5N1) virus (bird flu virus). H5N1 Bird flu virus can be transmitted from live birds to people; however, transmission between humans is very rare. There have not been any human infections with H5N1 bird flu virus in the United States. | |
Some had said that my 6 year old would not need a booster if she gets the nasal spray for H1N1. But if she received the shot then she would need a booster. Is it true that the nasal spray does not require a second dose? | ||
A: | The CDC Advisory Committee on Immunization Practices (ACIP) recommends that children under 10 years of age receive 2 doses of the 2009 H1N1 vaccine (either inactivated or nasal spray), separated by 4 weeks. The live-attenuated intranasal vaccine (LAIV), or the nasal spray, can be administered to healthy, non-pregnant persons aged 2 through 49 years for which no other contraindications to vaccination exist. We recommend that you consult with your child's pediatrician or healthcare provider for further guidance. He or she is aware of your child's medical history and would be able to provide the most appropriate medical advice. | |
I got my H1N1 flu shot over 2 weeks ago. Can I still get the flu even though I got my shot? I have asthma. Will I need a second shot? My doctor never told me if I should get another shot. | ||
A: | Everyone with asthma, aged 6 months to 64 years, should get the 2009 H1N1 flu shot. Children aged 6 months through 10 years will require 2 doses of the 2009 H1N1 vaccine. Persons aged 10 years and older only need one dose of the H1N1 vaccine. Clinical trials sponsored by the National Institutes of Health (NIH) indicate that most healthy children and adults will develop a protective level of antibody 21 days after receipt of the 2009 H1N1 influenza vaccine. However, some recipients, such as elderly persons or those with underlying medical conditions may require a longer time to develop a response to the vaccine, and some may not develop a protective response. | |
What is the MINIMUM time suggested between the first dose and the second dose of the H1N1 vaccine given to young children? There is a clinic local to me on day 25 - is this too soon? | ||
A: | CDC recommends that the 2 doses of 2009 H1N1 vaccine be separated by 4 weeks. But, if the second dose is given at least 21 days after the first dose, the second dose is valid. The United States Food and Drug Administration (FDA) has approved the use of 1 dose of 2009 H1N1 influenza (flu) vaccine for people 10 years of age and older. It's likely that children younger than 10 years will need 2 doses of 2009 H1N1 flu vaccine. This is slightly different from CDC's recommendations for seasonal flu vaccination, which state that children younger than 9 who are being vaccinated against influenza for the first time need to receive 2 doses. For more information about minimum time between first dose and second dose of the H1N1 vaccine on children, please visit the CDC website: http://www.cdc.gov/h1n1flu/vaccination/acip.htm | |
My 2 yr old is finishing up an antibiotic for an ear ache (Amoxicillin). Is it okay for him to get the H1N1 shot while taking this medicine? | ||
A: | Antibiotics (drugs that fight bacterial illness) have no effect on influenza (flu) viruses or flu vaccines. A person taking an antibiotic may get:
However, if the person taking the antibiotic has a moderate or severe acute illness, he or she should wait to get vaccinated until they are no longer ill.
| |
Everyone in our family has had both their seasonal and H1N1 flu shots (except for our newborn). Do we still need to be abundantly careful to keep our newborn from getting the flu? | ||
A: | There are steps mothers and caretakers can take to protect their infant from the spread of germs that cause respiratory (breathing tract) illnesses like 2009 H1N1 flu.
Child care programs cannot promise that flu will not spread in their program. Young children are at higher risk for flu complications (health problems). So, parents should carefully consider if their children should continue to attend the child care program. Avoiding infection is one of the most important protective steps against any flu virus. For most people, this will include ordinary measures such as avoiding close contact with people who are ill. Regular handwashing, avoiding crowds, and remaining several feet away from people who are coughing can limit the spread of germs. | |
I was able to get my two children vaccinated (2 and 4) and I am wondering how much protection they get from the first of two shots? I know in 3 weeks they need another, but I am wondering if the 1st shot offers any protection. | ||
A: | The first flu vaccine dose "primes" the immune system, the second dose provides immune protection. Children who only get one dose, but need two doses, can have reduced or no protection from a single dose of flu vaccine. Two doses are necessary to protect children. Children 9 years or younger need two doses, so be sure to follow up with the second dose. It usually takes about two weeks after the second dose for protection to begin. | |
How long after vaccination is immunization achieved? | ||
A: | It takes about 2 weeks after you receive your vaccination for antibodies to develop and provide protection from the flu. Both the flu shot and the nasal-spray flu vaccine work in the same way. They cause antibodies to develop in the body. These antibodies provide protection against flu virus infection. In the meantime, you are still at risk for getting the flu. That's why it is usually better to get the vaccine early. | |
Should my kids get H1N1 shots even they don't have medical problems? | ||
A: | CDC's Advisory Committee on Immunization Practices (ACIP) recommends that all children between 6 months and 18 years of age get the 2009 H1N1 vaccine. This is because there have been many cases of 2009 H1N1 influenza (flu) in children. They are also in close contact with each other in school and day care settings, which increases the likelihood of spreading the disease. The 2009 H1N1 influenza (flu) vaccine has a similar safety profile as seasonal flu vaccines, which have a very good safety track record. Vaccines, like any medication, can have side effects. But, in general, it's more dangerous to get sick with the virus than it is to get the vaccine. If you have any questions or concerns about whether your child should get the novel H1N1 vaccine, talk to his or her doctor. The H1N1 vaccine is not a replacement for the seasonal flu vaccine. It's important that children also get the seasonal flu vaccine as soon as it becomes available in your community. The H1N1 vaccine is to be given in addition to the seasonal flu vaccine. | |
I am a healthcare worker and I received the H1N1 flumist. I would like to know how long do I have to stay away from patients on the unit where there are pregnant women and babies? | ||
A: | The current estimated risk of getting infected with vaccine virus after close contact with a person vaccinated with the nasal-spray flu vaccine is low (0.6 to 2.4 percent). Because the viruses are weakened, infection is unlikely to result in influenza illness symptoms. These weakened vaccine viruses have not been shown to change into typical or naturally occurring influenza viruses. Healthcare workers in neonatal intensive care units (NICU) can get either the inactivated injectable influenza vaccine (flu shot) or the live attenuated influenza vaccine (LAIV) (nasal spray) for protection against 2009 H1N1 and seasonal influenza. Nearly all healthy non-pregnant health care workers may receive LAIV if otherwise eligible, including those who come in contact with:
However, LAIV should not be used for health care personnel who care for patients undergoing bone marrow transplantation (i.e. patients who require a protected environment). No special precautions (e.g., masks or gloves) are necessary for health care personnel who have been vaccinated with the LAIV and who do not work with patients undergoing bone marrow transplantation However, as a precautionary measure, the Advisory Committee on Immunization Practices (ACIP) recommends healthcare providers who were vaccinated with LAIV and who work with patients undergoing bone marrow transplantation, avoid providing care for such patients for 7 days after vaccination. LAIV transmission from a recently vaccinated person causing clinically important illness in an immunocompromised contact has not been reported. The rationale for avoiding use of LAIV among healthcare providers of severely immunocompromised patients is the theoretical risk that a live, attenuated vaccine virus could be transmitted to the severely immunosuppressed person.

What is the MAXIMUM time that can occur between the first dose and second dose of an H1N1 vaccination for young children? | ||
A: | There is no maximum interval between the two doses of the H1N1 influenza vaccine. We expect the second dose to provide immunity whether it is given 30 days, 60 days, or a year after the first. | |
My 5 year old child received two doses of the H1N1 flu shot today by mistake. How will this affect my child? | ||
A: | Most of the time, the risk of serious side effects does not increase if you or someone you know gets extra doses of a vaccine. But, there is a greater risk of a response at the site where the vaccine was given. This is most common after extra doses of certain vaccines, such as DTaP (diphtheria, tetanus, and pertussis. It is also very likely to happen if the time between doses is shorter than recommended. These reactions can be unpleasant, but they are not life threatening. Any adverse event following vaccination should be reported to the Vaccine Adverse Event Reporting System (VAERS). | |
If there is not enough flu vaccine, would it help to take the pneumonia vaccine? | ||
A: | There are many strains of viruses and bacteria that cause pneumonia (lung infection). The pneumococcal polysaccharide vaccine (PPSV) does not prevent all cases of pneumonia. The PPSV only protects against invasive pneumococcal disease. CDC recommends the vaccine for:
The PPSV also does not boost well. This means that, if you receive the vaccine as a young adult, and are not at risk for invasive disease, you will have less protection from the vaccine when you are over age 65. After age 65, everyone is at risk of invasive disease, regardless of high-risk conditions. People who develop influenza (flu) (H1N1 or seasonal) are at risk for non-invasive pneumococcal pneumonia. For this reason, vaccination with PPSV is only recommended for groups at risk of invasive pneumococcal disease. Healthy people less than age 65 are not recommended to get PPSV. If you are 65 years of age, or older, you should get the pneumococcal shot, Pneumovax. You should also get this shot if you are over 2 years of age and have a long-term health problem. This includes:
Children 2 years of age and older who have a device that helps them hear should also get the shot. This device is called a cochlear implant. You should also get the shot if you are over 2 years of age and have an illness that lowers your body's ability to fight off other illnesses. This includes:
You should also get the shot if you are over 2 years of age and are taking any drug that lowers your body's ability to fight off illnesses. This includes:
Finally, Alaska Natives and certain Native American populations should also get the shot. Talk to your doctor about getting the pneumococcal shot. It is the best way to keep from getting the illness. | |
Can you have the vaccine if you currently have cold/flu symptoms? | ||
A: | If you are moderately or severely ill, you might be advised to wait until you recover before getting the vaccine. If you have a mild cold or other illness, there is usually no need to wait. | |
My 2 yr old is finishing up an antibiotic for an ear ache. Is it okay for him to get the H1N1 shot while taking this medicine? ear ache. Is it okay for him to get the H1N1 shot while taking this medicine? | ||
A: | Antibiotics (drugs that fight bacterial illness) have no effect on influenza (flu) viruses or flu vaccines. A person taking an antibiotic may get:
However, if the person taking the antibiotic has a moderate or severe acute illness, he or she should wait to get vaccinated until they are no longer ill. | |
What is the risk for hospital kitchen staff workers if they have the flu (knowingly or unknowingly) and preparing the food? What is the likelihood of the food being contaminated with flu viruses? | ||
A: | Food (both raw and cooked) is not thought to be a means of transmission for either seasonal or 2009 H1N1 influenza viruses. Thus, a food handler with influenza does not present a risk to the safety of food. Any ill employee (food handler or otherwise) should be kept away from well people to prevent the spread of influenza through the normal routes of infection (inhaling virus expelled by infected individuals when coughing or sneezing or by touching a contaminated surface and then touching mucous membranes such as the mouth, nose or eyes.) More information can be found under the section on 'Food Safety, at this flu.gov website. | |
My son had a rapid flu test that came out positive. He never had a fever, only a stuffy nose and cough. Is it possible to get a false positive result? | ||
A: | Rapid influenza diagnostic tests detect seasonal flu A and B antigens, which are cells that make the body produce infection-fighting cells. The H1N1 2009 flu virus is an influenza A virus. Data are not yet available to determine whether rapid flu diagnostic tests can be used for patients with the H1N1 2009 virus infection. CDC has received some reports of false positive and false negative results using the rapid tests. A doctor may use a rapid diagnostic test as part of the evaluation, but results should be interpreted with caution. Confirmation of novel H1N1 flu infection can only be made with:

Where and how does a healthcare professional order the H1N1 vaccine? | ||
A: | State and local public heath departments are responsible for directing the flow of vaccine to providers within every state. They will determine which providers will receive vaccine and will allocate vaccine among providers as it becomes available to them. Distribution of the 2009 H1N1 vaccine will be a health department managed process. If you have not already done so, please contact your state health department for information on 2009 H1N1 vaccine distribution plans or on becoming a 2009 H1N1 vaccine provider.

Is it true that the "swine flu" isn't species specific and can pass from and to pets? I have a service dog... how best do I protect us both? | ||
A: | Certain pets are susceptible to human flu viruses. This includes:
Many animal species are also susceptible to other flu viruses. This includes:
But, these flu viruses have mostly remained within their own species. To date, several pigs, some turkeys, 2 ferrets, and a cat have likely been infected with 2009 H1N1 virus from exposure to infected humans. For more information about H1N1 flu, please visit this flu.gov website. You may also contact your state health department for additional information and guidance. Here is a link to finding state health departments. | |
How much of a risk does avian H5N1 influenza still pose despite all this talk of H1N1? | ||
A: | The current risk to Americans from the avian influenza A (H5N1) virus (bird flu virus) found in Asia, Europe, Africa, and the Near East is very low. There is no evidence of H5N1 virus having caused disease in birds or people in the United States. Avian influenza, also known as bird flu, is not the same as the seasonal flu that causes illness among people in the United States during the winter months. Avian influenza is a disease of birds, caused by infection with different kinds of influenza A viruses. The virus that has been reported in Asia, Europe, Africa, and the Near East, and has caused extensive outbreaks of disease among poultry and some wild birds is the avian influenza A (H5N1) virus. Bird flu viruses do not usually infect humans. All influenza (flu) viruses have the ability to change and mutate. Avian influenza A (H5N1) virus (bird flu virus) is a virus to which most people have little pre-existing protection (immunity). H5N1 virus infection has caused severe illness and death in humans in Asia, the Middle East and Africa. In fact, over 60 percent of people infected with H5N1 have died. If the H5N1 virus were to gain the ability to spread easily from person to person, a worldwide outbreak of disease (flu pandemic) could begin. The current risk to Americans from the H5N1 bird flu found in Asia, Europe, Africa, and the Near East is very low. There is no evidence of this H5N1 bird flu virus having caused disease in birds or people in the United States. Regularly updated information about human H5N1 cases is available on the World Health Organization (WHO) Web site, and updates on H5N1 animal outbreaks are reported on the website of the World Organization for Animal Health. | |
I work at a high school in the Health Office. I have heard everything from reports of a new "mutated killer virus" to there being Squaline in the H1N1 vaccine that it causes Lupus. Is there some where I can direct parents to dispel these rumors? | ||
A: | Flu.gov maintains a page of information about the latest Myths & Facts where you can get straight answers about H1N1 and vaccine rumors. Additionally, you can search and find the answers to more than 500 questions at: Answers.Flu.gov | |
Do you need the vaccine if you've already had a confirmed case of H1N1 this season. And what about those family members in the same house as the person who had the confirmed case? | ||
A: | People who had an illness confirmed by rRT-PCR to be 2009 H1N1 virus earlier in 2009 can be considered to be immune and do not need to be vaccinated this year. rRT-PCR is the only test that can confirm infection specifically with the 2009 H1N1 virus. All persons in a recommended vaccination target group who had an influenza (flu)-like illness that was not confirmed as 2009 H1N1 virus infection by real-time reverse transcription-polymerase chain reaction (rRT-PCR) should get the 2009 H1N1 vaccine. Most people ill with a flu-like illness since this spring have not been tested with rRT-PCR. Tests such as rapid antigen detection assays and diagnoses based on symptoms alone without rRT-PCR testing cannot specifically determine if a person has 2009 H1N1 flu. Persons who were not tested, but who became ill after being exposed to a person with lab-confirmed 2009 H1N1 flu, should not assume that they also had 2009 H1N1 as many pathogens can cause a flu-like illness. These people should get the vaccine if they are in a recommended vaccination target group. People who were infected with the 2009 H1N1 virus and who are not severely immune compromised will likely have immunity to subsequent infection with 2009 H1N1 virus. However, vaccination of a person with some existing immunity to the 2009 H1N1 virus will not be harmful, and patients who are uncertain about how they were diagnosed should get the 2009 H1N1 vaccine. The 2009 H1N1 virus does not provide protection against seasonal influenza viruses. Therefore, people who get the 2009 H1N1 vaccine should also get a seasonal vaccine. | |
If I get the nose spray flu vaccination with the live virus, will I be able to pass on the flu? | ||
A: | In clinical studies, live vaccine viruses were rarely passed to close contacts. | |
Can my son get the seasonal flu shot if he was diagnosed 2 days ago with strep and is on antibiotics? | ||
A: | In regards to your question about the antibiotics that your son is taking for strep infection, antibiotics have no effect on any type of influenza vaccine. In general you should always talk to your doctor before getting a flu shot if you:
If you are sick with a fever when you go to get your flu shot, talk to your doctor or nurse about getting your shot at a later date. However, you can get a flu shot if you have a respiratory (breathing) illness without a fever; or if you have another mild illness. If you have questions or concerns about your child getting the seasonal flu vaccine and/or the novel H1N1 vaccine, talk to their doctor. | |
After you get the H1N1 vaccine, how long until it is effective? | ||
A: | In adults, about 2 weeks after vaccination, antibodies that provide protection against 2009 H1N1 influenza virus infection will develop in the body. | |
I came in touch with an H1N1 victim 4 days ago. At that time he had runny nose. Yesterday he was tested positive for H1N1. Should I stay at home, even though I do not have any symptoms? Should I get a H1N1 test conducted for myself? | ||
A: | The time between exposure to the seasonal influenza (flu) virus and the beginning of flu symptoms is generally from 1 to 4 days, with an average of about 2 days. If you think you may have influenza (the flu), talk to your doctor. He or she can help you determine if you are infected. Many people with 2009 H1N1 influenza (flu) may continue to shed virus at lower levels 24 hours after their fevers go away. So, if you have a flu-like illness, you should make sure to:
| |
Should you get the H1N1 vaccination if you have already had the flu? Can you get it more than once? | ||
A: | You are unlikely to get infected with the same exact strain of influenza (flu) more than once. Most people with flu-like illness since spring 2009 don't know whether they were infected with 2009 H1N1 or another flu virus strain. If you think you had 2009 H1N1 infection, ask your doctor if you should be vaccinated. The only sure way to diagnose 2009 H1N1 infection is with real-time reverse transcription-polymerase chain reaction (RT-PCR). Even if you had a confirmed case of 2009 H1N1 flu, you can still get infected with other flu strains. You should make sure you get the seasonal flu vaccine. If you had a flu-like illness since spring 2009 that wasn't diagnosed as 2009 H1N1 flu by RT-PCR, get the H1N1 and seasonal flu vaccines. | |
What is an over the counter medicine that one can take who may have the flu? | ||
A: | If you have flu-like symptoms, you can purchase the following medications, which are available at your local drug store or pharmacy. These generic drugs are commonly identified by their brand or over-the-counter name:
If you are sick, see your doctor. Flu can lead to, or occur with, bacterial infections. Therefore, some people will also need to take antibiotics (drugs that kill bacteria) if they have:
An illness that seems to get better but then gets worse again. | |
From a business standpoint if there is a confirmed case of H1N1 in the home is it still safe to allow that employee to come to work if he/she is not sick? What are the chances of it being transferred to family members? | ||
A: | An employee with an ill household member may go to work. It is especially important that these employees monitor themselves for illness. Employees with school-aged children may need to stay home to care for their children. Employers should review leave policies for the flexibility to allow employees to stay home if they need to care for their children or other household members. If flu conditions are more severe, CDC guidance for school-aged children is that they should stay home for 5 days from the time someone in their home became sick. However, this guidance does not apply to adults. People infected with seasonal and 2009 H1N1 influenza (flu) shed virus and may be able to infect others from 1 day before getting sick to 5 to 7 days after. This can be longer in some people, especially:
Many people with flu illness will continue shedding flu virus 24 hours after their fevers go away, but at lower levels than during their fever. In some cases, shedding of flu virus can be detected for 10 days or more by reverse-transcription polymerase chain reaction (RT-PCR). So, when people who have had flu-like illness return to work, school, or other community settings, they should:
Because some people may shed flu virus before they feel ill, and because some people with flu will not have a fever, it's important that all people:

A: | The 2009 H1N1 nasal spray vaccine should also not be given to:
People who have a severe (life-threatening) allergy to eggs, or any other substance in the vaccine, should not get the 2009 H1N1 live, attenuated intranasal vaccine (LAIV) (nasal spray vaccine). If you are moderately or severely ill, you might be advised to wait until you recover before getting the vaccine. If you have a mild cold or other illness, there is usually no need to wait. Tell your doctor (or the person giving you the vaccine) know if you have ever had:
These may not be reasons to avoid the H1N1 flu vaccine, but the medical staff can help you decide. 2009 H1N1 nasal spray vaccine (LAIV) may be given at the same time as most other vaccines, except the seasonal flu nasal spray vaccine. The H1N1 nasal spray vaccine and the seasonal nasal spray vaccine should not be given together. These vaccines must be given at least 4 weeks apart. Tell your doctor if you:

Should you get the vaccine if you just recovered from the swine flu or if you have been around someone with it? | ||
A: | All persons in a recommended vaccination target group who had a flu-like illness that was not confirmed as 2009 H1N1 virus infection by real-time reverse transcription-polymerase chain reaction (rRT-PCR) test should get the 2009 H1N1 vaccine. People who had an illness confirmed by rRT-PCR to be 2009 H1N1 virus earlier in 2009 can be considered to be immune and do not need to be vaccinated this year. rRT-PCR is the only test that can confirm infection specifically with the 2009 H1N1 virus. Most people ill with a flu-like illness since this spring have not been tested with rRT-PCR. Tests such as rapid antigen detection assays and diagnoses based on symptoms alone without rRT-PCR testing cannot specifically determine if a person has 2009 H1N1 flu. Persons who were not tested, but who became ill after being exposed to a person with lab-confirmed 2009 H1N1 flu, should not assume that they also had 2009 H1N1 as many pathogens can cause a flu-like illness. These people should get the vaccine if they are in a recommended vaccination target group. People who were infected with the 2009 H1N1 virus and who are not severely immune compromised will likely have immunity to subsequent infection with 2009 H1N1 virus. However, vaccination of a person with some existing immunity to the 2009 H1N1 virus will not be harmful, and patients who are uncertain about how they were diagnosed should get the 2009 H1N1 vaccine. The 2009 H1N1 virus does not provide protection against seasonal influenza viruses. Therefore, people who get the 2009 H1N1 vaccine should also get a seasonal vaccine. Until you are able to get vaccinated, the best way to help fight 2009 H1N1 influenza (flu) is to cover your nose and mouth with a tissue when you cough or sneeze, then throw the tissue away. Wash your hands often with soap and water, especially after coughing or sneezing. Stay home if you're sick, and limit contact with others to keep from infecting them. | |
What can I do if I am allergic to eggs and can't get the vaccine? | ||
A: | CDC and the Advisory Committee on Immunization Practices (ACIP) recommend the use of antiviral drugs (drugs that fight viruses) for people who:
Taking antiviral drugs may also be recommended for people who may not have a good immune (body defense) response to the flu vaccine. | |

A: | On June 11, 2009, the World Health Organization (WHO) declared Pandemic Phase 6 for novel H1N1 influenza (flu). Raising the alert level to Pandemic Phase 6 for this outbreak of flu means that the current novel H1N1 flu spreading involves sustained human-to-human transmission (spread) in 2 or more regions of the world. Pandemic Phase 6 is an indicator of spread and not of severity of illness. Because there is already widespread novel H1N1 disease in the U.S., the WHO Phase 6 declaration does not change what the U.S. is currently doing to keep people healthy and protected from the virus. Thus there is no change to CDC's recommendations for individuals and communities. | |
Our concern is that can a cockroach carry the H1N1 virus if someone at the school gets it? | ||
A: | The spread of 2009 H1N1 virus is thought to happen in the same way that seasonal flu spreads within homes or communities. Flu viruses are spread mainly from person to person through coughing or sneezing by people who are sick with flu. People may become infected by touching something with flu viruses on it, and then touching their mouth or nose before washing their hands. Until you are able to get vaccinated, the best way to help fight 2009 H1N1 influenza (flu) is to cover your nose and mouth with a tissue when you cough or sneeze, then throw the tissue away. Wash your hands often with soap and water, especially after coughing or sneezing. Stay home if you're sick, and limit contact with others to keep from infecting them. We recommend that you contact your state health department for guidance regarding schools and public buildings with cockroaches. | |
Can you get the seasonal flu shot if you are not feeling well? | ||
A: | If you are sick with a fever when you go to get your flu shot, talk to your doctor or nurse about getting your shot at a later date. However, you can get a flu shot if you have a respiratory illness without a fever; or if you have another mild illness. The nasal-spray influenza (flu) vaccine can be given to people with minor illnesses, such as:
If a person has nasal congestion, he or she should consider waiting to get the nasal-spray flu vaccine. He or she may want to wait until the nasal congestion is reduced. This is because the nasal congestion may limit the vaccine's ability to reach the nasal lining. Definitely talk to your doctor before getting a flu shot if you:
If you any questions about whether you should get a flu shot, talk to your doctor or healthcare provider. | |
What about cancer patients? The ones that have just finished their chemo treatments. | ||
A: | Two types of H1N1 influenza vaccine are available in the United States:
2009 H1N1 LAIV should not be given to people with illnesses that weaken the immune system, or who take medications that can weaken the immune system. Please see: http://www.cdc.gov/h1n1flu/vaccination/nasalspray_qa.htm The following are recommendations from CDC and the Advisory Committee for Immunization Practices (ACIP). “We recommend that immunosuppressed persons be vaccinated with inactivated influenza vaccine. This recommendation applies to both seasonal and pandemic influenza vaccines. As a general rule, persons vaccinated while immunosuppressed should be revaccinated when their immune competence improves.” People who are in contact with others with severely weakened immune systems when they are being cared for in a protective environment (for example, people with hematopoietic stem cell transplants), should not get the nasal spray vaccine, including the 2009 H1N1 nasal spray vaccine if they will come into contact with the severely immunocompromised person within 7 days of vaccination. People who have contact with others with lesser degrees of immunosuppression (for example, people with diabetes, people with asthma taking corticosteroids, or people infected with HIV) can get the nasal spray vaccine. Basically, the contraindications for the H1N1 vaccines are the same as for seasonal flu vaccines, which you can read about in the Advisory Committee on Immunization Practices (ACIP) influenza vaccine recommendations for 2009/2010 at the following link: http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5808a1.htm Except for influenza vaccine, which should be administered annually, vaccination during chemotherapy or radiation therapy should be avoided if possible because antibody response might be suboptimal. However, administration of inactivated vaccines during chemotherapy or radiation is not contraindicated. Patients vaccinated within 2 weeks before starting immunosuppressive therapy or while receiving immunosuppressive therapy should be considered unvaccinated and should be revaccinated at least 3 months after therapy is discontinued if immune competence has been restored. To access these recommendations, please refer to: http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5515a1.htm Additionally, you may wish to review the following chart: “Vaccination of Persons with Primary and Secondary Immune Deficiencies” http://www.cdc.gov/vaccines/pubs/pinkbook/downloads/appendices/A/immuno-table.pdf Vaccine Information Statement (VISs) monovalent H1N1 influenza vaccines, both inactivated (shot) and live (nasal spray) have been published and are available on the CDC website at: http://www.cdc.gov/vaccines/pubs/VIS/default.htm#h1n1live The vaccine package insert for live attenuated H1N1 vaccine lists all vaccine ingredients and discusses any known adverse reactions. To review the package insert corresponding to Influenza A (H1N1) 2009 Monovalent Vaccine Live, Intranasal Vaccine, please visit the Food and Drug Administration (FDA) website at: http://www.fda.gov/BiologicsBloodVaccines/Vaccines/ApprovedProducts/ucm181970.htm | |
This may sound like a silly question, but can the H1N1 or any flu, be passed along to a family pet? | ||
A: | Influenza A viruses normally seen in one species can sometimes cross over and cause illness in another species [e.g., H1N1 (swine flu) viruses do not normally infect humans; however, sporadic human infections with swine flu have occurred]; however, no information is currently available about the 2009 H1N1 (swine flu) crossing over to pets such as dogs and cats. | |
I have heard that white vinegar can be used as a disinfectant. Would a spray bottle with vinegar and water be effective to kill flu germs? | ||
A: | Influenza (the flu) virus is destroyed by exposure to heat of 167 to 212 degrees Fahrenheit (75 to 100 degrees Centigrade).
These products are effective if the right amount is used for the right period of time. For example, wipes or gels with alcohol in them can be used to clean hands. The gels should be rubbed in until they are dry. Please note, the U.S. Environmental Protection Agency (EPA) offers a list of sterilizers and antimicrobial products that are registered with the EPA. You may access these lists at the following web links: "Antimicrobial Products Registered for Use Against Influenza A Virus on Hard Surfaces" "Antimicrobial Products Registered for Use Against the H1N1 Flu and Other Influenza A Viruses on Hard Surfaces" | |
What is: Non Differentiated Flu (undifferentiated)? Is this the same as FLU C? | ||
A: | There are three types of influenza viruses: A, B and C. Human influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. The emergence of a new and very different influenza virus to infect people can cause an influenza pandemic. Influenza type C infections cause a mild respiratory illness and are not thought to cause epidemics. | |
I have a disability -- can my employer require me take a flu vaccine? | ||
A: | No, an employee may be entitled to an exemption from a mandatory vaccination requirement based on an ADA disability that prevents him from taking the influenza vaccine. This would be a reasonable accommodation barring undue hardship (significant difficulty or expense). Similarly, under Title VII of the Civil Rights Act of 1964, once an employer receives notice that an employee’s sincerely held religious belief, practice, or observance prevents him from taking the influenza vaccine, the employer must provide a reasonable accommodation unless it would pose an undue hardship as defined by Title VII (“more than de minimis cost” to the operation of the employer’s business, which is a lower standard than under the ADA). Generally, ADA-covered employers should consider simply encouraging employees to get the influenza vaccine rather than requiring them to take it. For more workplace questions and answers, go to: | |
What strains of flu does the seasonal flu shot give protection for, excluding H1N1? | ||
A: | The 2009 to 2010 flu vaccine protects against the three main flu strains that research indicates will cause the most illness during the flu season. This year’s influenza vaccine contains three new influenza virus strains. They are as follows:
The 2009 to 2010 influenza vaccine can protect you from getting sick from these three viruses, or it can make your illness milder if you get a related but different influenza virus strain.
| |
If a person is allergic to latex can they still receive the flu vaccine? | ||
A: | A person with an anaphylactic allergy to latex shouldn't get vaccines supplied in vials or given with syringes that contain dry natural rubber or natural rubber latex. But, if the benefit of the vaccine outweighs the risk for a life-threatening response, they can get the vaccine. | |
Is the nasal spray seasonal flu vaccine as effective as the shot? | ||
A: | Both the flu shot and the nasal-spray flu vaccine provide good protection against influenza when they match the influenza strains circulating that season. The live, attenuated flu vaccine spray is approved for people from 2 through 49 years of age, who are not pregnant and do not have certain health conditions. Influenza vaccination is recommended for people who can spread influenza to others at high risk, such as:
Health care providers may also recommend a yearly influenza vaccination for:
People living in dormitories, correctional facilities, or under other crowded conditions, to prevent outbreaks. | |
I have Bell's Palsy and I want to know if I can get the H1N1 vaccine? | ||
A: | Influenza vaccine has not been shown to increase the risk of Bell's Palsy. A history of Bell's Palsy is not a reason to defer influenza vaccination. If you have questions or concerns about when you should get the seasonal flu vaccine and/or if you should get the novel H1N1 vaccine, talk to you doctor. For more information about H1N1 influenza virus, please visit the resources below: Flu.gov Vaccination Page Flu.gov H1N1 Page | |
I've recently heard that if a child gets the live attenuated H1N1 or seasonal flu vaccine for the first dose, it is okay if he/she receive a different formulation for the second dose? | ||
A: | Ideally, first and second doses would be from the same product. However, practical considerations make this difficult to implement. Planners should assume they will be interchangeable. For more information see these sites: CDC: http://www.cdc.gov/h1n1flu/vaccination/statelocal/qa.htm FDA: http://www.fda.gov/BiologicsBloodVaccines/Vaccines/ApprovedProducts/ucm181950.htm | |
At work, they are putting together a team to develop Policies & Procedures. Do you have any suggestions? | ||
A: | A flu response plan should have several components.

How will you treat pregnant women if they have the flu? | ||
A: | Pregnant women are at higher risk for severe complications and death from influenza, including both 2009 H1N1 influenza and seasonal influenza. Treatment with oseltamivir (Tamiflu®) or zanamivir (Relenza®) is recommended for pregnant women with suspected or confirmed influenza and can be taken during any trimester of pregnancy. The duration of antiviral treatment is 5 days. For additional information, see the Updated Interim Recommendations for Obstetric Health Care Providers Related to Use of Antiviral Medications in the Treatment and Prevention of Influenza for the 2009-2010 Season, http://www.cdc.gov/H1N1flu/pregnancy/antiviral_messages.htm | |
How long (one season or more) will immunity be effective from the H1N1 vaccine? Will this be an annual vaccine like the seasonal flu? | ||
A: | Influenza (flu) viruses change from year to year. You are unlikely to get infected with the same exact strain of influenza (flu) more than once. Most people with flu-like illness since spring 2009 don't know whether they were infected with 2009 H1N1 or another flu virus strain. If you think you had 2009 H1N1 infection, ask your doctor if you should be vaccinated. The only sure way to diagnose 2009 H1N1 infection is with real-time reverse transcription-polymerase chain reaction (RT-PCR). Even if you had a confirmed case of 2009 H1N1 flu, you can still get infected with other flu strains. You should make sure you get the seasonal flu vaccine. If you had a flu-like illness since spring 2009 that wasn't diagnosed as 2009 H1N1 flu by RT-PCR, get the H1N1 and seasonal flu vaccines. Also, a vaccine made against flu viruses circulating last year may not protect against the newer viruses. That is why the influenza vaccine is updated every year to include current viruses. | |
We have a patient who was diagnosed earlier this year with the H1N1 Flu. What would the protocol be for giving him the vaccine? | ||
A: | All persons in a recommended vaccination target group who had a flu-like illness that was not confirmed as 2009 H1N1 virus infection by real-time reverse transcription-polymerase chain reaction (RT-PCR) should get the 2009 H1N1 vaccine. RT-PCR is the only test that can confirm infection specifically with the 2009 H1N1 virus. Most people ill with a flu-like illness since this spring have not been tested with RT-PCR. Tests such as rapid antigen detection assays and diagnoses based on symptoms alone without RT-PCR testing cannot specifically determine if a person has 2009 H1N1 flu. Persons who were not tested, but who became ill after being exposed to a person with lab-confirmed 2009 H1N1 flu, should not assume that they also had 2009 H1N1 as many pathogens can cause a flu-like illness. These people should get the vaccine if they are in a recommended vaccination target group. A patient who had 2009 H1N1 infection diagnosed by RT-PCR may also want to get vaccinated. If the person is not severely immune compromised, he or she will likely have some immunity to subsequent infection with 2009 H1N1 virus. But, vaccination of a person with some existing immunity to the 2009 H1N1 virus will not be harmful. The following resources are available: H1N1 Flu Vaccination Resources: http://www.cdc.gov/h1n1flu/vaccination/ Novel H1N1 Influenza: Resources for Clinicians http://www.cdc.gov/h1n1flu/clinicians/ | |
Is H1N1 the same as influenza A? If not what is the difference? | ||
A: | Yes, novel H1N1 flu is a respiratory (breathing tract) disease caused by type A influenza (flu) virus. There are three types of influenza viruses: A, B and C. Influenza A and B viruses cause seasonal epidemics of disease almost every winter in the United States. Influenza type C infections cause a mild respiratory illness and are not thought to cause epidemics. Influenza A viruses are divided into subtypes based on two proteins on the surface of the virus: the hemagglutinin (H) and the neuraminidase (N). There are 16 different hemagglutinin subtypes and 9 different neuraminidase subtypes, Influenza A viruses can be further broken down into different strains. The current subtypes of influenza A viruses found in people are A (H1N1) and A (H3N2). Influenza B viruses are not divided into subtypes. Influenza B viruses also can be further broken down into different strains. Influenza A (H1N1), A (H3N2), and influenza B strains are included in each year's influenza vaccine. Getting a flu vaccine can protect against influenza A and B viruses. The flu vaccine does not protect against influenza C viruses.

Do you have a sample policy statement for businesses who want to let folks know to stay home if they are sick? | ||
A: | You may want to consider using this type of message: If you are sick with the flu, you may be ill for a week or longer. You should stay home and keep away from others as much as possible, including avoiding travel and not going to work or school, for at least 24 hours after your fever is gone except to get medical care or for other necessities. (Your fever should be gone without the use of fever-reducing medicine.) If you leave the house to seek medical care, wear a facemask, if available and tolerable, and cover your coughs and sneezes with a tissue. In general, you should avoid contact with other people as much as possible to keep from spreading your illness, especially people at increased risk of severe illness from influenza. With seasonal flu, people may be contagious from one day before they develop symptoms to up to 7 days after they get sick. Children, especially younger children, might potentially be contagious for longer periods. People infected with the novel H1N1 are likely to have similar patterns of infectiousness as with seasonal flu. You may also be interested in reviewing the toolkit for businesses on the CDC website at: Questions and Answers about CDC’s Guidance for Businesses and Employers to Plan and Respond to the 2009-2010 Influenza Season | |
What chronic health conditions would be considered priority for the vaccination when it becomes available? Heart Murmur? Hypothyroidism? | ||
A: | Medical risk factors for severe infection are similar to those identified previously in studies of seasonal influenza. In one case series of 179 patients hospitalized with laboratory-confirmed novel influenza A (H1N1) virus infection, 117 (65 percent) patients had a medical risk factor previously associated with severe infection in studies of seasonal influenza (e.g., chronic heart, lung, renal, liver disease; cancer or immunosuppression; or pregnancy). The initial target groups include persons who have medical conditions that put them at higher risk for influenza-related complications. These medical conditions are defined as: “Chronic medical conditions that confer a higher risk for influenza-related complications include chronic pulmonary (including asthma), cardiovascular (except hypertension), renal, hepatic, cognitive, neurologic/neuromuscular, hematologic, or metabolic disorders (including diabetes mellitus) or immunosuppression (including immunosuppression caused by medications or by human immunodeficiency virus)” | |
How do you diagnose an H1N1 flu infection? | ||
A: | To diagnose novel H1N1 flu infection, your doctor may decide to collect a respiratory specimen, and send it to a CDC lab for testing. This specimen is a sample of the fluid from your nose or throat. The specimen generally needs to be collected within the first 4 to 5 days of illness. This is when the infected person is most likely to be shedding virus. But some people, especially children, may shed virus for 10 days or longer. For more information about testing procedures, see the CDC’s Interim Guidance on Specimen Collection, Processing, and Testing for Patients with Suspected Novel Influenza A (H1N1) Virus Infection, http://www.cdc.gov/h1n1flu/specimencollection.htm | |
What makes this strain of Swine Flu different from the influenza of the same name back in the 60's and 70's? | ||
A: | The viruses detected in the U.S. in April 2009 are different from the H1N1 flu virus that caused the 1976 outbreak. Most genetic parts of these viruses are similar to H1N1 viruses from the North American lineage. However, there are also parts of the virus similar to H1N1 viruses of the Eurasian lineage. | |
If I had the swine flu in the 1970's, will I be immune to this one? | ||
A: | The 1976 swine flu virus and the 2009 H1N1 virus are different enough that it's unlikely a person vaccinated in 1976 will have full protection from the 2009 H1N1 virus. People vaccinated in 1976 should still be given the 2009 H1N1 vaccine. Meanwhile, until the vaccine is available, the best way to help fight novel H1N1 influenza is to cover your nose and mouth with a tissue when you cough or sneeze, then throw the tissue away. Wash your hands often with soap and water, especially after coughing or sneezing. Stay home if you're sick, and limit contact with others to keep from infecting them. For more information, please refer to the following CDC web pages: | |
At what age is one considered to be in the "senior" or "elderly" category among the H1N1 high risk groups? | ||
A: | Current studies show that the risk for novel H1N1 infection among people age 65 or older is less than the risk for younger age groups. Overall, seniors have been spared from the novel H1N1 virus. However, even though people age 65 and older are not at high risk of infection with H1N1, they are at high risk for seasonal influenza (flu). So, you should get the seasonal flu vaccine as soon as it becomes available in your area. | |
What is the incubation period of the H1N1 (swine) flu? | ||
A: | The estimated incubation period is unknown and could range from 1 to 7 days, and more likely 1 to 4 days. Persons with novel H1N1 flu virus infection should be considered potentially contagious (able to spread disease) for up to 7 days after illness onset. Persons who continue to be ill longer than 7 days should be considered potentially contagious until symptoms have resolved. Children, especially younger children, might be contagious for longer periods. Stay home until at least 24 hours after you no longer have a fever (100°F or 37.8°C) or signs of a fever (without the use of a fever-reducing medicine, such as Tylenol®). Read detailed information about how long to stay away from others. It's important to remember that we are still in flu and allergy season and it's not uncommon to have cold or flu-like symptoms. If you are sick, stay home from work or school to monitor your health. If you do have symptoms where you think you need urgent care, contact your doctor right away. | |
Can LYSOL brand disinfectant protect against the flu virus? | ||
A: | Influenza virus, or the flu virus, is destroyed by exposure to heat of 167 to 212 degrees Fahrenheit (75 to 100 degrees Centigrade). There are also several chemical germicides (substances that kill disease-causing germs) that are effective against flu viruses, such as:
| |
What are the initial symptoms of swine flu? How do we get it cured on immediate basis? | ||
A: | The symptoms of novel H1N1 flu in people are expected to be similar to the symptoms of regular human seasonal flu infection. They include:
Some people with novel H1N1 flu have also reported:
Like seasonal flu, novel H1N1 flu in people can vary in severity from mild to severe. Severe disease with pneumonia (a lung infection), respiratory failure, and even death is possible with novel H1N1 flu infection. Certain groups might be more likely to develop a severe illness from novel H1N1 flu infection, such as persons with chronic medical conditions. Sometimes bacterial infections may occur at the same time as or after infection with flu viruses and lead to pneumonia, ear infections, or sinus infections. Ill people should also check with their healthcare provider about whether they should take antiviral medications (drugs that fight viruses). Flu can lead to, or occur with, bacterial infections. Therefore, some people will also need to take antibiotics (drugs that kill bacteria) if they have:
People with novel H1N1 flu who are cared for at home should check with their healthcare provider about any special care they might need, especially if they are pregnant or have a health condition such as diabetes, heart disease, asthma, or emphysema. Also, persons with novel H1N1 flu virus infection should be considered potentially contagious (able to spread disease) for up to 7 days after illness onset. Persons who continue to be ill longer than 7 days should be considered potentially contagious until symptoms have resolved. Children, especially younger children, might be contagious for longer periods. If you are sick with H1N1 flu,

What is the history of the 2009 Swine Flu? | ||
A: | A Virus Emerges Novel influenza A (H1N1) is a new flu virus of swine origin that first caused illness in Mexico and the United States in March and April, 2009. It’s thought that novel influenza A (H1N1) flu spreads in the same way that regular seasonal influenza viruses spread, mainly through the coughs and sneezes of people who are sick with the virus, but it may also be spread by touching infected objects and then touching your nose or mouth. Novel H1N1 infection has been reported to cause a wide range of flu-like symptoms, including fever, cough, sore throat, body aches, headache, chills and fatigue. In addition, many people also have reported nausea, vomiting and/or diarrhea. The first novel H1N1 patient in the United States was confirmed by laboratory testing at CDC on April 15, 2009. The second patient was confirmed on April 17, 2009. It was quickly determined that the virus was spreading from person-to-person. On April 22, CDC activated its Emergency Operations Center to better coordinate the public health response. On April 26, 2009, the United States Government declared a public health emergency and has been actively and aggressively implementing the nation’s pandemic response plan. A Pandemic Is Declared On June 11, 2009, the World Health Organization (WHO) signaled that a global pandemic of novel influenza A (H1N1) was underway by raising the worldwide pandemic alert level to Phase 6. This action was a reflection of the spread of the new H1N1 virus, not the severity of illness caused by the virus. At the time, more than 70 countries had reported cases of novel influenza A (H1N1) infection and there were ongoing community level outbreaks of novel H1N1 in multiple parts of the world. By June 19, 2009, all 50 states in the United States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands reported novel H1N1 infection. While nationwide U.S. influenza surveillance systems indicate that overall influenza activity is decreasing in the country during the summer, novel H1N1 outbreaks are ongoing in parts of the U.S., in some cases with intense activity. Since the WHO declaration of a pandemic, the new H1N1 virus has continued to spread, with the number of countries reporting cases of novel H1N1 nearly doubling. The Southern Hemisphere’s regular influenza season has begun and countries there are reporting that the new H1N1 virus is spreading and causing illness along with regular seasonal influenza viruses. In the United States, significant novel H1N1 illness has continued into the summer, with localized and in some cases intense outbreaks occurring. The United States continues to report the largest number of novel H1N1 cases of any country worldwide, however, most people who have become ill have recovered without requiring medical treatment. Given ongoing novel H1N1 activity to date, the CDC anticipates that there will be more cases, more hospitalizations and more deaths associated with this pandemic in the United States over the summer and into the fall and winter. The novel H1N1 virus, in conjunction with regular seasonal influenza viruses, poses the potential to cause significant illness with associated hospitalizations and deaths during the U.S. influenza season. | |
Will the new H1N1 vaccine be safe, even for children? Are you testing it? | ||
A: | CDC's Advisory Committee on Immunization Practices (ACIP) recommends that all children between 6 months and 18 years of age get the novel H1N1 vaccine. This is because there have been many cases of novel H1N1 influenza (flu) in children. They are also in close contact with each other in school and day care settings, which increases the likelihood of spreading the disease. Vaccine trials for the novel H1N1 flu are currently being conducted. You can contact the National Institute of Allergy and Infectious Diseases (NIAID), which is conducting the trials for the vaccines. For more information, please visit the following Web sites: Questions and Answers: Clinical Trials of 2009 H1N1 Influenza Vaccines Conducted by the NIAID-Supported Vaccine and Treatment Evaluation Units http://www3.niaid.nih.gov/news/QA/vteuH1N1qa.htm NIAID Set to Launch Clinical Trials to Test 2009 H1N1 Influenza Vaccine Candidates http://www3.niaid.nih.gov/news/newsreleases/2009/VTEU_H1N1.htm Once the trials have been completed and more information is known about the vaccine, more information will be available through the CDC. Please continue to check the Flu.gov Web site for the latest information on vaccines. Please note: The H1N1 vaccine is not a replacement for the seasonal flu vaccine. It's important that your child also gets the seasonal flu vaccine as soon as it becomes available in your community. The H1N1 vaccine is to be used with the seasonal flu vaccine. Vaccines, like any medication, can have side effects. But, in general, it's more dangerous to get sick with the virus than it is to get the vaccine. If you have any questions or concerns about whether you, or someone you know, should get the novel H1N1 vaccine, you should talk to a doctor. For more information about novel H1N1 vaccine recommendations, please visit the CDC Web site: | |
What are the implications of H1N1 for the elderly? | ||
A: | Current studies show that the risk for novel H1N1 infection among people age 65 or older is less than the risk for younger age groups. Overall, seniors have been spared from the novel H1N1 virus! However, even though people age 65 and older are not at high risk of infection with H1N1, they are at high risk for seasonal influenza (flu). So, they should get the seasonal flu vaccine as soon as it becomes available in their area. General prevention guidelines for all individuals can be found on the CDC website at: For more information about novel H1N1 flu, please visit the CDC website: | |
What are the rules for health care workers who have family members diagnosed with H1N1 or whose family members have tested positive by nasal swab? | ||
A: | Hospitals and clinics should ask sick staff to stay home. All personnel should self monitor daily for signs and symptoms of febrile respiratory illness. Staff who develop these symptoms should be instructed not to report to work, or if at work, should cease patient care activities and notify their supervisor. If you have not already done so, please contact your state health department for guidance specific to your area. A directory of state health departments is available online at: http://www.statepublichealth.org/index.php?template=directory.php Please refer to the following guidance: Interim Guidance for Infection Control for Care of Patients with Confirmed or Suspected Swine Influenza A (H1N1) Virus Infection in a Healthcare Setting http://www.cdc.gov/h1n1flu/guidelines_infection_control.htm As noted in the above, healthcare personnel who do not have a febrile respiratory illness may continue to work. Interim guidance on antiviral recommendations for close contacts of patients with confirmed or suspected swine influenza A (H1N1) virus infection can be found at http://www.cdc.gov/h1n1flu/recommendations.htm. CDC's new guidance regarding the amount of time people with flu-like illness should be away from others (exclusion period) does not apply to healthcare settings. CDC has provided a separate guidance for healthcare settings. The recommendations for healthcare settings remain at 7 days after symptoms began or until all symptoms are gone, whichever is longer. Additional clinical guidance is available on the CDC website: Interim Guidance for Clinicians and Public Health Professionals http://www.cdc.gov/h1n1flu/guidance/ This is an evolving situation and CDC will provide updated guidance and new information for clinicians as it becomes available. | |
Do you have special recommendations for air conditioned buildings? | ||
A: | The CDC indicates that the odds of transmission of the 2009-H1N1 influenza over significant distances through heating, ventilation, and air conditioning (HVAC) systems is extremely remote and special cleaning of air ducts is not required. For guidance related to the prevention of transmission of H1N1 influenza virus in healthcare setting, please refer to the following: Interim Guidance for Infection Control for Care of Patients with Confirmed or Suspected Swine Influenza A (H1N1) Virus Infection in a Healthcare Setting http://www.cdc.gov/h1n1flu/guidelines_infection_control.htm If you have concerns about a building and the transmission of disease, please contact your state health department for guidance.

Are there any precautions to take at church? For example surfaces of contact, Pews, hynmals, etc. | ||
A: | The CDC recommends that faith-based and community organizations contact your state department of health and your organization's leadership for guidance on developing policies to prevent the spread of novel H1N1 in your area. A directory of state health departments is available online at: http://www.statepublichealth.org/index.php?template=directory.php Influenza (flu) viruses may be spread when a person touches droplets left by coughs and sneezes on hard surfaces (such as desks or door knobs) or objects (such as keyboards or pens) and then touches his or her mouth or nose. But, it's not necessary to disinfect these surfaces beyond routine cleaning. You should clean surfaces and items that are more likely to have frequent hand contact with cleaning agents that are usually used in these areas. You may be interested in the following checklist: Faith-Based and Community Organizations Pandemic Influenza Preparedness Checklist As the above notes, Faith-Based and Community Organizations should evaluate the organization’s usual activities and services (including rites and religious practices if applicable) to identify those that may facilitate virus spread from person to person. The organization should up policies to modify these activities to prevent the spread of pandemic influenza (e.g. guidance for respiratory hygiene and cough etiquette, and instructions for persons with influenza symptoms to stay home rather than visit in person.) Community-based and faith-based service organizations can help teach their members about how to stay healthy. They also can offer support to families by providing meals, transportation, and other services to make it easier to stay home if a family member is sick or school is dismissed.

Can I use an N95 mask for more than one day? | ||
A: | N95 respirators should be worn only once and then thrown away in the trash. When using facemasks or N95 respirators, please remember:
Very little is known about the benefits of wearing facemasks or respirators to help control the spread of influenza in community settings. In areas with confirmed influenza virus infections, the risk for infection can be reduced through a combination of actions. No single action will provide complete protection, but an approach combining the following steps can help decrease the likelihood of transmission. These actions include frequent handwashing, covering coughs, and having ill persons stay home, except to seek medical care, and minimize contact with others in the household. People should consider wearing a facemask during a severe influenza (flu) outbreak if:
During a severe flu outbreak, people should limit the amount of time they spend in crowded places. They should also consider wearing a facemask while in crowded areas. People should consider wearing a respirator during a flu pandemic if:
In these situations, people should limit the amount of time they are in close contact with those who are ill, and should consider wearing a respirator. If a respirator is unavailable, the use of a mask should be considered. Respirator use should be in the context of a complete respiratory protection program in accordance with Occupational Safety and Health Administration (OSHA) regulations. Information on respiratory protection programs and fit test procedures can be accessed at http://www.osha.gov/SLTC/etools/respiratory. Staff should be medically cleared, fit-tested, and trained for respirator use, including: proper fit-testing and use of respirators, safe removal and disposal, and medical contraindications to respirator use.

Could you tell me the symptoms of swine flu in babies? | ||
A: | If you or someone you know has a baby that may be sick, it is very important to take the baby for medical assessment. The symptoms of novel H1N1 flu in people are expected to be similar to the symptoms of regular human seasonal flu infection. They include:
Some people with novel H1N1 flu have also reported:
In children, emergency warning signs that need urgent medical attention include:
Like seasonal flu, novel H1N1 flu in people can vary in severity from mild to severe. Severe disease with pneumonia (a lung infection), respiratory failure, and even death is possible with novel H1N1 flu infection. Certain groups might be more likely to develop a severe illness from novel H1N1 flu infection, including children younger than 5 years old. Sometimes bacterial infections may occur at the same time as or after infection with flu viruses and lead to pneumonias, ear infections, or sinus infections. Also, persons with novel H1N1 flu virus infection should be considered potentially contagious (able to spread disease) for up to 7 days after illness onset. Persons who continue to be ill longer than 7 days should be considered potentially contagious until symptoms have resolved. Children, especially younger children, might be contagious for longer periods. People who are sick should stay home until at least 24 hours after they no longer have a fever (100°F or 37.8°C) or signs of a fever (without the use of a fever-reducing medicine, such as Tylenol®). Read detailed information about how long to stay away from others. For more information about novel H1N1 influenza virus, please visit the following: | |
What can I take if I have a fever with the flu or flu like symptoms? | ||
A: | If you have flu-like symptoms, you can purchase the following medications, which are available at your local drug store or pharmacy. These generic drugs are commonly identified by their brand or over-the-counter name:
Ill people should also check with their health care provider about whether they should take antiviral medications (drugs that fight viruses). If you are sick, see your doctor. Flu can lead to, or occur with, bacterial infections. Therefore, some people will also need to take antibiotics (drugs that kill bacteria) if they have:
People with novel H1N1 flu who are cared for at home should check with their health care provider about any special care they might need, especially if they are pregnant or have a health condition such as diabetes, heart disease, asthma, or emphysema; If you are sick with H1N1 flu,

What is the definition of fever for the purposes of diagnosing the flu? | ||
A: | CDC defines fever as a temperature of 100 degrees Fahrenheit or 37.8 degrees Celsius or greater without the use of fever-reducing medications. | |
Is there a rapid test available at my doctor's office or public health clinic for flu? | ||
A: | Rapid influenza (flu) diagnostic tests detect seasonal flu A and B antigens, which are cells that make the body produce infection-fighting cells. The novel H1N1 flu virus is an influenza A virus. Data are not yet available to determine whether rapid flu diagnostic tests can be used for patients with novel H1N1 virus infection. CDC has received some reports of false positive and false negative results using the rapid tests. A doctor may use a rapid diagnostic test as part of the evaluation, but results should be interpreted with caution. Confirmation of H1N1 flu infection can only be made with:
We recommend that you contact your healthcare provider and state health department for additional information and guidance as to the availability of flu rapid testing.

When should I get my seasonal flu shot? | ||
A: | Yearly flu vaccination should begin in September or as soon as the flu vaccine is available. Vaccination should continue throughout the flu season, into December, January, and beyond. This is because the timing and duration (length) of the flu season varies. While flu outbreaks can happen as early as October, most of the time, influenza activity peaks in January or later. Children under 9 years of age will need 2 doses of the vaccine the first year they are vaccinated. The first dose would ideally be given in September or as soon as the vaccine is available. The second dose should be given at least 28 days (4 weeks) after the first dose. If a child needs 2 doses, it is best to begin the process early so that the child is protected before flu season starts circulating in his or her community. Certain groups of people may benefit from vaccination as late as April or May. This is true even if flu viruses are no longer circulating in the U.S. These groups include:
The vaccine should continue to be offered to unvaccinated people throughout the flu season, as long as it is available. Please note the flu is contagious and can spread to your family and those you love. Protect yourself and your loved ones. Get the flu vaccine.

I have a serious lung disease. Will the pneumonia vaccine protect me from the flu? | ||
A: | People with serious lung diseases should talk to your doctor about vaccines you may need during an outbreak of the flu. All people who are recommended to have the pneumococcal vaccine should continue to be vaccinated according to current ACIP recommendations during the outbreak of novel influenza A(H1N1). You and your doctor may be interested in the CDC Advisory Committee on Immunization Practices (ACIP) recommendation. They say that a single dose of PPSV23 (the pneumococcal vaccine, Pneumovax) for all people 65 years and older and for persons 2 to 64 years of age with certain high-risk conditions is recommended. Please refer to this Web site for additional details:

How long can a virus like novel H1N1 live on a surface outside its host? | ||
A: | The H1N1 virus is new. Research is being conducted to better understand its characteristics. Studies have shown that flu viruses can survive on hard surfaces and can infect a person for up to 2 to 8 hours after being left on items like cafeteria tables, doorknobs, and desks. Frequent handwashing will help you reduce the chance of getting contamination from these common surfaces. Flu viruses may be spread when a person touches droplets left by coughs and sneezes on hard surfaces (such as desks or door knobs) or objects (such as keyboards or pens) and then touches his or her mouth or nose. But, routine cleaning will kill these germs. Until a vaccine is available, the best way to help fight novel H1N1 influenza (flu) is to cover your nose and mouth with a tissue when you cough or sneeze, then throw the tissue away. Wash your hands often with soap and water, especially after coughing or sneezing. Stay home if you're sick, and limit contact with others to keep from infecting them.

My daughter will be breast feeding this fall. Should she take the HINI flu vaccine? | ||
A: | When vaccine is first available, the Advisory Committee on Immunization Practices (ACIP) recommends that programs and providers try to vaccinate pregnant women, and people who live with or care for children younger than 6 months of age (e.g. new mothers). It is also recommended for persons between the ages of 6 months through 24 years of age. The novel H1N1 flu vaccines are currently undergoing clinical trials to better understand the risks and benefits. More will be known about the vaccine after these trials are completed in late summer or early fall. You may want to contact the National Institute of Allergy and Infectious Diseases (NIAID), as they are conducting the trials for the vaccines. For more information, please visit the following websites: Questions and Answers: Clinical Trials of 2009 H1N1 Influenza Vaccines Conducted by the NIAID-Supported Vaccine and Treatment Evaluation Units http://www3.niaid.nih.gov/news/QA/vteuH1N1qa.htm NIAID Set to Launch Clinical Trials to Test 2009 H1N1 Influenza Vaccine Candidates http://www3.niaid.nih.gov/news/newsreleases/2009/VTEU_H1N1.htm After the clinical trials are completed, more information on the vaccine should be available on the Flu.gov Web site. | |
What are the after effects of the swine flu? How long will they last? | ||
A: | It is expected that most people will recover without needing medical care. If you have severe illness or you are at high risk for flu complications, contact your health care provider or seek medical care. Your health care provider will determine whether flu testing or treatment is needed The symptoms of novel H1N1 flu in people are expected to be similar to the symptoms of regular human seasonal flu infection. They include:
Some people with novel H1N1 flu have also reported:
Like seasonal flu, novel H1N1 flu in humans can vary in severity from mild to severe. Severe disease with pneumonia (a lung infection), respiratory failure, and even death is possible with novel H1N1 flu infection. Certain groups might be more likely to develop a severe illness from novel H1N1 flu infection, such as persons with chronic medical conditions. Sometimes bacterial infections may occur at the same time as or after infection with flu viruses and lead to pneumonias, ear infections, or sinus infections. Ill people should also check with their healthcare provider about whether they should take antiviral medications (drugs that fight viruses). Flu can lead to, or occur with, bacterial infections.

If I’ve already had the H1N1 flu this year, can I get it again? | ||
A: | Please remember that the H1N1 virus is new and research is being conducted to better understand its characteristics. In addition, although data on H1N1 are scarce and this illness is still being studied, it is also important to know that flu viruses undergo frequent changes during an outbreak. In general, exposure to a particular strain of flu virus will protect you against that strain in the future. However, it will not protect you from infection by other flu virus strains. Please also note that it is possible for a person to be infected with the seasonal influenza (flu) virus more than one time in a season, because several strains of flu virus circulate each year. | |
I am allergic to eggs. Can I receive a flu shot even though I am allergic to eggs? | ||
A: | Talk to your doctor before getting a flu shot if you:
If you are sick with a fever when you go to get your flu shot, talk to your doctor or nurse about getting your shot at a later date. However, you can get a flu shot if you have a respiratory (breathing) illness without a fever; or if you have another mild illness. If you have questions about whether you should get a flu shot, talk to your doctor or healthcare provider.

Does hand washing work if there is no hot running water in any of the bathrooms? | ||
A: | The CDC recommends that you wash your hands thoroughly with clean, running water and soap. Use warm water if it’s available. If clean, running water is not available use an alcohol-based hand sanitizer. | ||
Why are people over 64 who have chronic ailments not eligible for the H1N1 flu vaccine? | ||
A: | First, everyone is eligible for the H1N1 flu vaccine, although some people may have health issues that would be affected by a vaccine and therefore should not take it. The goal of the pandemic influenza vaccination program is to vaccinate all persons in the United States who choose to be vaccinated. More than $8 billion is being invested in developing enough vaccine for everyone who needs it. Because the vaccines may be released gradually beginning in October, a priority list is developed to focus on immediate immunization for:
In past pandemics, groups at increased risk for serious illness and death have differed by age and health status. Specifically, during the 1918 pandemic previously healthy, young adults were a high-risk group. As we have studied the current outbreak, we now know which groups are most vulnerable — younger people, pregnant women, health care personnel, and people who have underlying health conditions. Immunizing these groups first will help contain the spread of the flu during the vaccination roll-out which may take a few months. Here are the statistics on who is most vulnerable to the novel H1N1 flu:
