Human Infections With Novel Reassortant Influenza A(H3N2)v Viruses, United States, 2011

Emerg Infect Dis. 2012 May;18(5):834-7. doi: 10.3201/eid1805.111922.

Abstract

During July-December 2011, a variant virus, influenza A(H3N2)v, caused 12 human cases of influenza. The virus contained genes originating from swine, avian, and human viruses, including the M gene from influenza A(H1N1)pdm09 virus. Influenza A(H3N2)v viruses were antigenically distinct from seasonal influenza viruses and similar to proposed vaccine virus A/Minnesota/11/2010.
