A Boone County child who contracted a new strain of swine flu has become the first Illinois case of the illness this year. The Illinois Department of Public Health announced the case of H3N2v influenza virus Thursday. The child has mild symptoms and had contact with swine at the DuPage County Fair in late July. The virus is typically transmitted from swine to humans. Health officials are urging the public to avoid contact with pigs and to wash hands frequently before and after exposure to animals. The new flu's severity has been compared to regular seasonal flu. It's also been reported in Indiana and Ohio this year. The virus first appeared in swine in 2011. The first human cases were reported last year and included four cases in Illinois.
