Swine flu

Swine influenza is a respiratory disease of pigs first isolated in swine in 1930, according to the Centers for Disease Control and Prevention. The illness is caused by four different type A influenza strains that can cause outbreaks in pigs, though subtypes H1N1 and H3N2 seem to be more common. The death rate among pigs is low, with most infections occurring in the late fall and winter. Symptoms of infected pigs include fever, depression, coughing (barking), sneezing, difficulty breathing, red or inflamed eyes, lack of appetite and discharge from the nose or eyes. Read more>>
