General Information


On April 29th, 2009, the World Health Organization announced that it would no longer refer to the H1N1 Influenza A virus as 'swine flu' to avoid giving a false understanding of the danger posed by pigs.

Viruses regularly cause outbreaks of influenza among pigs. These viruses do not normally infect humans; however, since March 2009, a number of confirmed human cases of a new strain of swine-origin H1N1 Influenza A virus infection in the U.S. and internationally have been identified. Although to date the infection appears to be similar to seasonal flu in severity, the rapid global spread of the virus prompted the World Health Organization to declare a pandemic in June.


  • Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissues in the trash after you use it.
  • Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hand cleansers also are effective.
  • Avoid touching your eyes, nose or mouth
  • Avoid close contact with sick people.
  • Influenza is thought to be spread mainly person-to-person through coughing or sneezing of infected people.
  • If you get sick, stay home from work or school and limit contact with others to keep from infecting them.
  • Try to stay in good general health. Get plenty of sleep, be physically active, manage your stress, drink plenty of fluids, and eat nutritious food.
  • Try not to touch surfaces that may be contaminated with the flu virus.
