Of interest, the USA Centers for Disease Control and Prevention (CDC) has reported four cases of swine influenza A(H3N2) virus in children in the states of Indiana (1 case) and Pennsylvania (three cases).
The virus is similar to one that has been circulating in swine since 1998 and which has been previously identified in eight human cases.
The viral genome contains seven of the eight gene segments from the circulating swine H3N2 viruses, including the hemaglutinin and neuraminidase genes, however, it is unique in that it contains one gene segment, the M gene, derived from the pandemic influenza A(H1N1) virus.
The Indiana case did not have direct exposure to pigs but had contact with a care-giver who did have recent swine contact.
The three cases in Pennsylvania had all recently visited a fair where swine were present.
The virus does not appear to have spread widely in humans; however, investigations are ongoing.
For more information, see the CDC Morbidity and Mortality Weekly Report, September 9, 2011 / 60(35);1213-1215 and the Pennsylvania Department of Health website.
