Week 49 Flu View cites the detection of H1N1v in case in Minnesota with no documented swine contact.

Novel Influenza A Virus:

One human infection with a novel influenza A virus was reported by the state of Minnesota. The person was infected with an influenza A (H1N1) variant (H1N1v) virus. The patient was not hospitalized and has fully recovered from their illness. The patient lived and worked in an area near where swine were housed but no direct contact with swine was reported in the week prior to illness onset. No ongoing human-to-human transmission has been identified.

Early identification and investigation of human infections with novel influenza A viruses are critical so that the 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 at http://www.cdc.gov/flu/swineflu/index.htm.
