Virginia H3N2v Case Raises Concerns

An additional case of H3N2v infection has been confirmed in a non-Virginia resident who had close and prolonged contact with pigs at a fair in the northwest region of the state

The above comments from a Virginia Department of Health July 26 press release describe the first H3N2v case linked to a Virginia agricultural fair. The above location and exposure date correspond to the Fauquire County Fair, which ran from July 16-July 23 and is located in northwest Virginia (see map). The attendee is a resident of Ohio and was diagnosed in Ohio, so the patient is cited as an Ohio case in today’s CDC FluView and H3N2v case count.

The early appearance of an H3N2v case in Virginia, coupled with the 13th 2013 H3N2v case in Indiana, raises concerns that the 2013 total may top the record number of confirmed H3N2v cases in 2012, when the first cases linked to fairs were cited exactly one year ago for the LaPorte County Fair in Indiana. It is not clear if the latest case from Indiana is again linked to that fair, but the CDC has released the sequence, A/Indiana/10/2013, from a July 16 collection, and the H3 sequence has N145R and is viritually identical to the 2013 cases linked to the Hancock County Fair (see map).
