Background Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus –Regularly causes outbreaks of influenza in pigs Like all influenza viruses, swine flu viruses change constantly –Pigs can be infected by avian influenza and human influenza viruses as well as swine influenza viruses. When influenza viruses from different species (birds, pigs, humans) infect pigs, the viruses can reassort (i.e. swap genes) Sporadic human infections with swine flu have occurred

Swine Flu – Symptoms The symptoms of swine flu in people are expected to be similar to the symptoms of regular human season influenza and include fever, cough, rhinorrhea, sore throat, malaise, fatigue, lack of appetite. Some people with swine flu also have reported runny nose, sore throat, nausea, vomiting and diarrhea.

Swine Flu – Transmission Thought to occur in the same way as seasonal flu occurs in people –Person-to-person transmission through coughing or sneezing of people infected with the influenza virus –People may become infected by touching something with flu viruses on it and then touching their eyes, mouth or nose.
