FYI The latest flu strain is H3N2v Here’s some general information:

Influenza A viruses circulating in pigs that have infected humans are referred to as “variant” viruses. Human infections with an influenza A (H3N2) variant (H3N2v) virus that contains the M gene from the influenza A(H1N1)pdm09 virus (2009 H1N1 pandemic virus) were first detected in 2011. Of note, a large increase in cases of H3N2v virus infection has been identified since July 2012. (This virus has been circulating among pigs in the United States since 2011, has been detected in pigs in many states, and appears to be circulating widely in swine in the United States.) Most H3N2v cases have been in children, although some adults have been infected, and are linked to recent direct or indirect exposure to pigs.

To date, almost all of the H3N2v cases in 2012 have been epidemiologically linked to agricultural fairs, either through exhibiting pigs or walking through a swine barn. Occupational exposure to pigs was reported in 1 case. Limited, nonsustained human-to-human transmission of H3N2v virus was noted in 2011, including in households and a childcare setting. Since 2011, a small number of H3N2v case patients have been hospitalized, including previously healthy people and people with chronic underlying conditions. To date, no deaths have occurred and all cases have recovered fully. CDC is monitoring the situation closely with state health departments and will issue updates accordingly as additional information becomes available.
