Swine influenza, or “swine flu”, is a highly contagious acute respiratory disease of pigs, caused by one of several swine influenza A viruses. Morbidity tends to be high and mortality low (1-4%). The virus is spread among pigs by aerosols, direct and indirect contact, and asymptomatic carrier pigs. Outbreaks in pigs occur year round, with an increased incidence in the fall and winter in temperate zones. Many countries routinely vaccinate swine populations against swine influenza.
How can I protect myself from getting swine influenza from infected people?
To protect yourself, practice general preventive measures for influenza:
Avoid close contact with people who appear unwell and who have fever and cough.
Wash your hands with soap and water frequently and thoroughly.
Practice good health habits including adequate sleep, eating nutritious food, and keeping physically active.
