CDC Shortcut: General Questions and Answers on 2009 H1N1 Influenza Vaccine Safety

SUNY Downstate is closely monitoring information and guidance from the Centers for Disease Control and Prevention (CDC), the New York State Department of Health and the New York City Department of Health and Mental Hygiene about H1N1 Influenza (Swine Flu) in our region.

We urge you to remain aware of advisories, and to take everyday actions to stay healthy.

For Patients and Visitors:

For mild symptoms and non-urgent medical conditions, patients should call their regular physician for guidance and advice first before heading to an emergency department. This ensures that our community's urgent care resources are reserved for the patients who need them most.

If severe symptoms develop, call your healthcare provider. If the healthcare provider is not available, go to the emergency room.

Where To Get a Flu Shot:

Vaccinations against flu viruses are the best way to prevent illness, and we urge everyone in the CDC priority groups for H1N1 flu and seasonal flu to take advantage of vaccinations as appropriate.

Flu shots are usually available from your primary care physician or pediatrician, as well as through local community clinics.

Downstate employees:

If you are feeling ill from influenza-like symptoms, you should notify your supervisor and stay home. If you need to seek medical attention, contact your primary care provider. If you develop flu symptoms while at work, you should seek care from Employee-Student Health Services. Do not go to the Downstate Emergency Room for care unless you have severe symptoms that require emergency care.

What is H1N1 influenza (Swine Flu)?

H1N1 is a new flu virus of that was first detected in April, 2009. The virus is infecting people and is spreading from person-to-person, and has sparked a growing outbreak of illness.

Although there have been some hospitalizations and several H1N1 flu-related deaths in New York City, the overwhelming majority of affected individuals continue to have only mild-to-moderate symptoms similar to ordinary seasonal influenza.

Most people recover in a few days. In most cases, H1N1 flu will resolve without medical attention.

How Is H1N1 Transmitted?

Transmission is predominately droplet, which means:

The flu virus is present:

  • In large droplets expelled when you cough or sneeze, which fall quickly to the ground or on to surfaces
  • On the hands of ill people.

Transmission occurs:

  • Usually from direct hand-to-hand or hand-to-surface contact.
  • Flu virus on the hands is easily transferred to the eyes, nose, and mouth, where flu virus can enter the body and cause infection.
  • Less frequently by direct inhalation of flu virus in the air.

Implication: Hand washing is as important as respiratory precautions.

Things You Can Do to Stay Healthy

Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.

Remember the 3-C's

1. Clean.
Wash your hands often. Scrub your hands for at least 20 seconds with soap and water or use an alcohol-based hand cleaner. Wash your hands after contact with respiratory secretions.

2. Cover.
Cover your cough. Use a tissue to cover your mouth and nose when you cough or sneeze. Do not have a tissue - The crook of your elbow will do.

3. Contain.
Contain germs by steering clear of others who are sick. Distance yourself from others (more than 3 feet). If you do get sick, stay at home until you're well again, so you do not spread more germs.

What you should do if you think you have H1N1 Influenza:


  • Do not go to work and, if your children are ill, keep them home from school. Do not go out to do errands, and limit close contact with others to keep from infecting them.
  • You should stay at home at least 7 days after your symptoms began or 1 day after your symptoms resolve - whichever is longer.
  • In most cases, H1N1 flu will resolve without medical attention.
  • Get plenty of rest
  • Take acetaminophen (Tylenol), ibuprofen, or other fever-reducing medicine as needed. Do NOT give apirin or aspirin-containing products to children and youth under 18 years old, to avoid Reyes Syndrome, a potentially life-threatening complication.
  • Drink clear fluids (such as water, broth, sports drinks, electrolyte beverages for infants) to keep from being dehydranted.
  • If medications are prescribed, be sure to follow instructions exactly. If you think you are having a reaction to the medication, report it to your healthcare provider immediately.
  • If you are at risk for complications of flu or sick, call your healthcare provider. Report your symptoms, and follow their advice.
