CONCORD, N.H. (AP) – No residents have been hit yet, but more birds and mosquitoes infected with West Nile virus and Eastern equine encephalitis have been found in New Hampshire.

The threat will ease soon, with the first killing frost, but until then, state Health and Human Services Commissioner John Stephen continues to urge residents to take precautions against mosquitoes.

The latest tests revealed Triple-E in mosquito pools in Newmarket, Hudson, Hampstead and East Kingston. A bird tested positive in Windham. West Nile was found in a bird in Danville.

Meanwhile, Nashua, Pelham and Hudson joined the list of communities under a public health threat, which previously included all of Rockingham County, Manchester, Madbury and other surrounding communities.

By declaring the public health threat, cities such as Nashua will be reimbursed by the state for some mosquito-control costs.

At least one school, Alvirne High School in Hudson, postponed a Friday night football game to Saturday morning as a result of the public health threat.

“The communities are working so well with us,” Stephen said. “The message is getting out, and people are responding. We’ve seen no human cases, and hopefully, we won’t see any. But this is still a very significant risk.”
