Swine Flu is a respiratory disease caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. The "classical" Swine Flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930. Swine flu viruses cause illness in pigs, but the death rates are low. This new virus, although it is being called "swine flu," is not the same virus.
