H1N1 Update


normal medium large

    The 2009 novel H1N1 influenza virus (initially and inaccurately referred to as "swine flu") is a new influenza virus causing illness in people around the world. This new virus was first detected in people in the United States and Mexico in April 2009. The 2009 novel H1N1 is spreading from person to person worldwide, probably in much the same way that regular seasonal influenza viruses spread.

    On June 11, 2009, the World Health Organization (WHO) signaled that a pandemic of 2009 novel H1N1 flu was underway—the word "pandemic" meaning that the flu is spreading simultaneously in multiple countries around the world. The 2009 novel H1N1 flu is already widespread across the nation, including New York, along with cases of what is called "seasonal" flu (although as of this date we are not yet seeing significant seasonal flu yet in this area).

    Stony Brook Medicine is providing this information to the public on how to prevent illness with the 2009 novel H1N1 flu, as well as seasonal flu, because prevention is the single best way to stay healthy and slow the spread of flu viruses.

    Information on this Web site has been obtained from the Centers for Disease Control and Prevention (CDC) and the New York State Department of Health.

    Check back here frequently. We will be updating our information as it is received.

    Much is known about the 2009 novel H1N1 influenza, and we are learning more every day. At the same time, new questions arise with regularity. In this section we will attempt to gather in one place the answers to the questions we are hearing most often about the flu. View latest frequently asked questions.


    Some Things You Can Do to Protect You and Your Family

    Get Vaccinated!
    Make sure the people in your family who are listed in the groups below are vaccinated. Vaccination is the best protection against contracting the flu. You need two vaccines—seasonal and 2009 novel H1N1—to be fully protected this year. The seasonal flu vaccine is different from the 2009 novel H1N1 flu vaccine. Children under age 10 must receive two doses of the 2009 novel H1N1 vaccine to be fully protected. The CDC is encouraging people to get all vaccinations as soon as possible. More information on Vaccination.

    Take these everyday steps to protect your health:

    Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
    Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleaners are also effective.
    Avoid touching your eyes, nose, or mouth. Germs spread this way.
    Try to avoid close contact with sick people. If you must have close contact with a sick person (for example, holding a sick infant), try to wear a face mask.
    Stay home if you are sick 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.
    Follow public health advice regarding school closures, avoiding crowds, and other social distancing measures.

    What to Do If You Get Sick

    If you experience any of the following symptoms, stay home, avoid contact with others, and drink plenty of fluids. These are typical symptoms of both the seasonal flu and 2009 novel H1N1 influenza.

    Extreme tiredness
    Dry cough
    Sore throat
    Runny or stuffy nose
    Muscle aches
    Stomach symptoms, such as nausea, vomiting, and diarrhea (more common in children than adults)

    If any of these symptoms worsen or new symptoms develop, or your fever goes away and then returns, contact your personal physician right away.

    The following high-risk persons should seek medical attention or guidance from their personal physician as soon as they develop any of the above symptoms:

    Pregnant women
    Children younger than 5 years of age
    Persons of any age with certain chronic medical conditions or compromised immune systems
    Persons 65 years and older (this population is thought to have less susceptibility to H1N1, but is known to be at high risk for seasonal flu)

    If you do come to the Emergency Department or Outpatient Clinic areas to be seen as a patient and you are experiencing these symptoms, please make sure you identify yourself as being ill with influenza-like illness. You will be asked to wear a mask (unless you cannot tolerate it because of your symptoms) in order to reduce the spread of infection and further protect you from contracting any other infection.

    If you do have flu-like symptoms, talk to your doctor about possible treatment with antivirals. Antiviral drugs are prescription medicines (pills, liquid, or an inhaler) that can be used for treatment or, in certain circumstances, prevention of flu viruses. If you get sick, antiviral drugs can make your illness milder and make you feel better faster. Antivirals can also reduce the chances of spreading the virus to others. Two types of antivirals, Oseltamivir (TAMIFLU®) and Zanamivir (RELENZA®) are currently effective against the 2009 H1N1 flu. For more information on medications and antivirals, click here.

    What Stony Brook Medicine Is Doing to Prevent Influenza Viruses from Spreading

    We take the health of our patients, our employees, and the community very seriously. There are "Keep It Clean!" stations installed throughout our Hospital facilities where anyone can get sanitizing wipes, tissues, hand hygiene products, and "Toss it!" bags for used wipes and tissues—all of which will help reduce the spread of viral and bacterial infections, including influenza.     

    In addition, we are:

    Offering employees influenza vaccines. We offer the seasonal influenza vaccine to all employees and will offer them the 2009 novel H1N1 vaccine as soon as it's available.
    Educating our staff and the public. We're working to educate the public and our staff about the importance of prevention and limiting the spread of influenza. In addition to promoting correct hand hygiene and cough etiquette, we are encouraging our staff to be vaccinated.
    Keeping sick patients protected. We have protective policies in place for healthcare workers, patients, and visitors alike, and we offer a surgical mask to any patient who is exhibiting flu-like symptoms. Our Hospital staff knows the importance of following this policy at all times.
    Promoting clean hands. We work hard to ensure that all healthcare workers and visitors clean their hands frequently and always when entering and leaving any patient's room. "Clean hands" is one of our most important messages, both within and outside the Hospital.
    Screening visitors. We are asking all visitors to avoid coming to the Hospital if they do not feel well.
    Protecting patients by ensuring that they do not come into contact with patient care employees who have the flu. If our caregivers get sick with the flu, they must stay home from work until they have been fever-free for 24 hours in accordance with the CDC recommendations. This will help prevent transmission of influenza from staff to patients.

    Groups Recommended to Receive the 2009 Novel H1N1 Influenza Vaccine

    Pregnant women because they are at higher risk of complications and can provide protection to newborns and infants who cannot be vaccinated.
    Household contacts and caregivers for children younger than 6 months of age because younger infants are at higher risk of influenza-related complications and cannot be vaccinated. Vaccination of those in close contact with infants younger than 6 months old might help protect infants by "cocooning" them from the virus.
    Healthcare and emergency medical services personnel because infections among healthcare workers have been reported, this group can be a potential source of infection for vulnerable patients. Also, increased absenteeism in this population could reduce healthcare system capacity, as ill caregivers will not be available to provide expert care.
    Everyone from 6 months through 24 years of age
    Children from 6 months through 18 years of age because cases of 2009 novel H1N1 influenza have been seen in children who are in close contact with each other in school and day care settings, which increases the likelihood of disease spread.
    sub-bulleted item Young adults 19 through 24 years of age because many cases of 2009 novel H1N1 influenza have been seen in these healthy young adults and they often live, work, and study in close proximity, and they are a frequently mobile population.
    sub-bulleted item Persons aged 25 through 64 years who have health conditions associated with higher risk of medical complications from influenza.

    NOTE: Current studies indicate that the risk for infection among persons age 65 or older is less than the risk for younger age groups. However, once vaccine demand among younger age groups has been met, programs and providers should offer vaccination to people 65 or older, as well as people ages 25 to 64.

    Nationwide, the 2009 novel H1N1 vaccination has begun but initial supplies are limited. More doses are expected for shipment each week. We ask members of the public who want to receive this vaccine to be patient as more vaccine becomes available. While we expect that there will eventually be enough vaccine available for anyone who wishes to receive it, the CDC's Advisory Committee on Immunization Practices (ACIP) also made recommendations regarding which people within the groups listed above should receive the first available doses. For more information see the CDC press release CDC Advisors Make Recommendations for Use of Vaccine Against Novel H1N1

    About Vaccines and Vaccinations: From the Centers for Disease Control and Prevention (CDC)

    About the CDC: The CDC is one of the major operating components of the U.S. Department of Health and Human Services. The CDC's mission is to collaborate to create the expertise, information, and tools that people and communities need to protect their health—through health promotion, prevention of disease, injury and disability, and preparedness for new health threats. The CDC seeks to accomplish its mission by working with partners throughout the nation and the world to monitor health, detect and investigate health problems, conduct research to enhance prevention, develop and advocate sound public health policies, implement prevention strategies, promote healthy behaviors, foster safe and healthful environments, and provide leadership and training.

    With the 2009 novel H1N1 virus continuing to cause illness, hospitalizations, and deaths in the U.S. during the normally flu-free summer months, and some uncertainty about what the upcoming seasonal flu season might bring, the ACIP met July 29, 2009, to make recommendations on who should receive the 2009 novel H1N1 vaccine. While some issues are still unknown, such as how severe the flu season will be, the ACIP considered several factors, including current disease patterns, populations most at-risk for severe illness based on current trends in illness, hospitalizations, and deaths, how much vaccine is anticipated, and the timing of vaccine availability. The 2009 novel H1N1 vaccination recommendations are described above and are also available at www.cdc.gov/mmwr/preview/mmwrhtml/rr58e0821a1.htm.

    Vaccines are one of the best tools available to prevent influenza. The CDC recommends vaccination against seasonal and 2009 novel H1N1 flu to prevent influenza. The seasonal flu vaccine does not provide protection against 2009 novel H1N1 influenza. The 2009 novel H1N1 vaccine is not intended to replace the seasonal flu vaccine—it is intended to be used alongside seasonal flu vaccine. 

    About Vaccine Safety: The 2009 novel H1N1 influenza vaccine is expected to have a similar safety profile as seasonal flu vaccines, which have a very good safety track record. Over the years, hundreds of millions of Americans have received seasonal flu vaccines.

    The CDC expects that any serious side effects following vaccination with the 2009 novel H1N1 influenza vaccine would be rare. If side effects occur, they will likely be similar to common ones experienced following seasonal influenza vaccine. Mild problems that may be experienced include soreness, redness or swelling where the shot was given, fainting (mainly adolescents), headache, muscle aches, fever, and nausea. If these problems occur, they usually begin soon after the shot and last 1 to 2 days.

    Life-threatening allergic reactions to vaccines are very rare. If they do occur, it is usually very shortly after the shot is given. If any unusual condition occurs following vaccination, seek medical attention right away.

    The Centers for Disease Control and Prevention and the Food and Drug Administration (FDA) will be closely monitoring for any signs that the vaccine is causing unexpected adverse events, and we will work with state and local health officials to investigate any unusual events occurring here.

    2009 Novel H1N1 Flu—Questions and Answers

    What is 2009 novel H1N1 flu?  The 2009 novel H1N1 flu is a new kind of influenza virus that was seen for the first time in the United States in April 2009. Health officials initially called it "swine flu" because it looked similar to some flu viruses of pigs. However, further study showed that 2009 novel H1N1 flu contains a combination of flu virus genes found in some humans and birds, as well as pigs.

    Is 2009 novel H1N1 flu the same as the flu that pigs get?   No. The swine flu that pigs get is a respiratory disease caused by a different influenza virus. Outbreaks of swine flu happen regularly in pigs. People do not normally get swine flu, although sometimes people who work or live around pigs can get it. Very rarely, people with swine flu can spread it to others.  

    What do these other flu names mean?  You may hear or see 2009 novel H1N1 flu called "2009 H1N1 flu," "novel H1N1 flu," or "pandemic (H1N1) 2009." These all refer to the same H1N1 flu. There is also a fully "human" H1N1, which is common during our usual flu season and which is covered by the seasonal flu vaccine.

    Is 2009 novel H1N1 flu the same as seasonal flu?  No. Some differences between seasonal flu and novel H1N1 flu are:

      Seasonal Influenza 2009 Novel H1N1 Flu
    When flu occurs Every year, usually winter and early spring First identified April 2009, continuing up to the present
    Age group most affected People 65 years and older Children and young adults
    Vaccine available Yes, available every year; available now Beginning in mid to late October 2009 and moving forward
