What is swine flu???
Swine Influenza (flu) is a respiratory disease of pigs caused by type A influenza viruses that causes regular outbreaks in pigs.The death rate among pigs is low, with most infections occurring in the late fall and winter. In the past there have been a few cases of swine flu transferred from person to person, but it was limited and not sustained beyond three people. Recently, however, the disease has been passed on from one person to another, even if they haven't had direct contact with pigs.
