New H1N2v flu case in Ohio involved swine exposure

Ohio officials have confirmed a case of novel H1N2 influenza (H1N2v), the US Centers for Disease Control and Prevention (CDC) said today in its weekly FluView update.

The case involves a child who had direct exposure to swine at a fair in the week preceding illness onset and has fully recovered, the CDC said. Officials confirmed the diagnosis last week, and no human-to-human transmission has been found. The agency provided no other details on the patient.

This is the first H1N2v case reported in 2017. The CDC has confirmed 13 cases of H3N2v, a much more common flu variant, so far this year, the most recent of them last week. Since 2015 the agency has reported 384 H3N2v cases, compared with 10 H1N2v cases and 20 H1N1v cases.

H1N2v contains genes from swine flu strains plus the M gene from the 2009 H1N1 flu virus.

The CDC said in today's update, "Early identification and investigation of human infections with novel influenza A viruses are critical to ensure timely risk assessment and so that 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."
