Influenza viruses that normally circulate in pigs are called “variant” when they are found in people.
The first cases were reported in June 2013, and the CDC anticipates identifying more cases as the agricultural fair season continues.
CDC recommends avoiding exposure to pigs and swine barns at fairs, washing hands frequently if engaged with activities that involve swine contact, and seeking medical care for influenza-like symptoms following direct or close contact with pigs.
