H1N1 (Swine) Flu Guidance



The information and recommendations posted on this page are compiled from multiple sources and is intended to provide the best information available at the time. This page will be updated as new information becomes available.

What is H1N1 (Swine Flu)?

H1N1, also known as Swine Flu, is a type A influenza virus that causes respiratory illness in pigs. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks in humans.

How does H1N1 (Swine Flu) spread?

Swine Flu SpreadsPeople do not normally get swine flu, but human infections do occur. Influenza viruses can be directly transmitted from live pigs to people and from people to pigs but not from eating pork or pork products. Human infections with the flu virus from pigs are most likely to occur when people are in close proximity to infected pigs such as in pig barns (1).

The 2009 H1N1 influenza virus that caused human illness is contagious and spreads from person to person in the same manner that seasonal flu spreads. The virus can be spread when a person infected with the influenza virus coughs or sneezes (1). Remember - a single sneeze can produce more than 40,000 droplets of moisture and millions of germs (2).

The virus can be spread when an infected person coughs or sneezes

People may also become infected by touching something with flu viruses on it and then touching their mouth or nose before washing their hands.

What about pork and pork products?

Swine influenza viruses are not transmitted by food. You can not get H1N1 flu from eating pork or pork products. Eating properly handled and cooked pork and pork products is safe. Cooking pork to an internal temperature of 160°F kills the virus as it does other bacteria and viruses (1).

Should I get vaccinated?


The CDC has recommended that individuals get vaccinated for the seasonal flu which is an important tool toward preventing influenza. The seasonal flu vaccine however is unlikely to protect you from H1N1 (swine flu). Therefore individuals should be vaccinated for the seasonal flu and for the H1N1 flu. 

Certain at-risk groups should receive the H1N1 vaccine:

      • Pregnant women.
      • Household contacts and caregivers for children younger than 6 months of age.
      • Health care and emergency medical services personnel.
      • People between the ages of 6 months through 24 years of age.
      • Persons aged 25 through 64 years who have health conditions associated with higher risk of medical complications from influenza.

Precautions and prevention tips:

Everyone should take precautions to avoid getting the flu or spreading it to others. Simple steps will minimize your risk:

    • Cover your nose and mouth with a tissue when you sneeze or cough. Throw the tissue away after you use it.
    • Cough or sneeze into your upper sleeve if you do not have a tissue.
    • Wash your hands often with soap and water, especially after coughing or sneezing.
    • When you do not have access to soap and water, use an alcohol-based hand sanitizer such as PurellRegistered trademark symbol.
    • Avoid touching your eyes, nose or mouth.
    • Clean and disinfect hard surfaces in common areas including doorknobs, telephone handsets, etc. This is important since the influenza virus can survive on surfaces and can infect a person for up to 2-8 hours after being deposited on the surface.
    • *If you are sick, limit your contact with other people as much as possible. Remain at home until at least 24 hours after you are free of fever (100° F [37.8°C]), or signs of a fever without the use of fever-reducing medications (CDC).
