The above comments on the Monroe County Fair in Bloomington, Indiana (which opened Saturday) strongly suggests that the H3N2v confirmed at the LaPorte County Fair (in exhibitors, family, and associated swine) has spread throughout Indiana (media reports cite symptomatic swine in Jackson and Hendricks counties also).
12 of 12 swine (including those which were asymptomatic) were H3N2v positive and reports indicate the swine H3N2v sequences were closely related to the the human cases. Two full sets of sequences from fair cases (A/Indiana/07/2012 and A/Indiana/09/2012) have been released by the CDC and they are closely related to the West Virginia cluster at an Mineral County day care center (A/West Virginia/06/2011 and A/West Virginia07/2011) which also involved 23 symptomatic contacts who did not have swine exposure.
Additional confirmed #H3N2v cases in 2012 include patients in Utah and Hawaii.
The emergence and evolution of this novel H3N2v sub-clade raises serious pandemic concerns.
