H1N1 influenza (swine flu)

H1N1 influenza, also known as "swine flu," is a newly identified virus that can spread from people who are infected to others through coughs and sneezes. When people cough or sneeze, they spread germs through the air or onto surfaces that other people may touch. H1N1 influenza is not transmitted from pigs to humans or from eating pork products. H1N1 influenza is a new virus to human populations, so people's bodies have little ability to fight H1N1 infection. To avoid spreading illness to others, people with symptoms of the flu should stay at home until any fever has been gone for at least 24 hours without the use of fever-reducing medicines.
