Eastern equine encephalitis virus found in horse

August 29, 2019

CONCORD, N.H. (AP) — The New Hampshire Department of Health and Human Services says it’s found the Eastern equine encephalitis virus in a horse in Northwood.

The department said Wednesday this is the first finding of the mosquito-transmitted virus in a horse this year, though a mosquito batch from Pelham tested positive for EEE two weeks ago.

The risk level for the town of Northwood will be increased to high, and the surrounding towns of Barnstead, Barrington, Deerfield, Epsom, Nottingham, Pittsfield, and Strafford will increase from low to moderate.

Since 2004, there have been 15 human infections with EEE identified in New Hampshire; the last human case of EEE in the state was in 2014, when there were three cases. There have been no EEE infections identified yet this season in humans.
