Influenza A (H1N1)

ExitCare ImageH1N1 formerly called "swine flu" is a new influenza virus causing sickness in people. The H1N1 virus is different from seasonal influenza viruses. However, the H1N1 symptoms are similar to seasonal influenza and it is spread from person to person. You may be at higher risk for serious problems if you have underlying serious medical conditions. The CDC and the World Health Organization are following reported cases around the world.


  • The flu is thought to spread mainly person-to-person through coughing or sneezing of infected people.

  • A person may become infected by touching something with the virus on it and then touching their mouth or nose.


  • Fever.

  • Headache.

  • Tiredness.

  • Cough.

  • Sore throat.

  • Runny or stuffy nose.

  • Body aches.

  • Diarrhea and vomiting

These symptoms are referred to as "flu-like symptoms." A lot of different illnesses, including the common cold, may have similar symptoms.


  • There are tests that can tell if you have the H1N1 virus.

  • Confirmed cases of H1N1 will be reported to the state or local health department.

  • A doctor's exam may be needed to tell whether you have an infection that is a complication of the flu.

  • Cover your nose and mouth with a tissue or your arm when you cough or sneeze. Throw the tissue away.

  • Wash your hands often with soap and warm water, especially after you cough or sneeze. Alcohol-based cleaners are also effective against germs.
