Influenza A H3N2 variant virus (H3N2v) is a strain of influenza A that
normally circulates among pigs. During 2011, the Centers for Disease
Control and Prevention (CDC) reported 12 human cases of H3N2v virus
infection. Most infections occurred among persons who had contact with
swine, however there was some evidence of limited human-to-human
transmission.
During July 1 - August 17, 2012, CDC reported an additional 225 cases
of human H3N2v infection from 9 states, including two Wisconsin cases.
The severity of human illness caused by H3N2v is similar to seasonal
influenza.
The CDC has posted helpful information about the H3N2v outbreak
including the national case count, how to prevent infection, information
for clinicians, specimen collection and testing guidance, and
information for schools, fair managers and swine exhibitors.
