Hospitalized H3N2v Case In Minnesota

[niman]

Novel Influenza A Viruses:

One human infection with a novel influenza A virus was reported by the state of Minnesota. The person was infected with an influenza A (H3N2) variant (H3N2v) virus and was hospitalized as a result of their illness. No human-to-human transmission has been identified and the case reported close contact with swine in the week prior to illness onset.

Early identification and investigation of human infections with novel influenza A viruses are critical so that risk of infection can be more fully appreciated and appropriate public health measures can be taken. Additional information on influenza in swine, variant influenza infection in humans, and strategies to interact safely with swine can be found athttp://www.cdc.gov/flu/swineflu/index.htm.
