- H3N2v: Swine influenza strain with triple re-assortment, emerging 2011-2013 in US. Strain noted previously in humans, but those cases related to swine exposure. No clear human-human sustained transmission documented to date, cases observed in 5 states and susceptible to neuraminidases. Children < 10 yrs may be most prone as older children and adults may have some immunity by exposure to earlier influenza strains. No clear indication of increased severity of disease . In June 2013, 4 cases reported in Indiana. Currently available vaccines do not cover H3N2v.
