NEWPORT, NH – A Newport resident tested positive for the Jamestown Canyon virus and was hospitalized with the mosquito-borne disease, which can cause fatigue and fever and, in rare cases, neurological problems such as a brain infection.

The Public Health Services Division of the New Hampshire Department of Health and Human Services announced Friday that the case involved a Newport adult who was hospitalized with left side weakness, unresponsiveness and multiple seizures. The person is staying in the hospital and their condition has not improved recently, DHHS said in a press release on Friday.

Although it is the end of the season when the virus is normally transmitted, DHHS raises the “arboviral risk” to “high” for Newport. The risk for the surrounding cities of Cornish, Croydon, Sunapee, Goshen, Unity and Claremont has been increased to “moderate” according to the press release.

The Newport case was the fifth to involve anyone in New Hampshire this year. Officials said there are no vaccines to prevent the virus and that treatment consists of rest and monitoring for escalating symptoms.

“Although JCV is still a rare disease, we are seeing more infections in New Hampshire, which is worrying,” said state epidemiologist Dr. Benjamin Chan in the press release.

The press release states that Jamestown Canyon virus is a “mosquito-borne pathogen that is widespread in North America, primarily between deer and mosquitoes,” and that transmission typically occurs between a spring thaw and a mosquito-dying frost in the fall.

This is the 14th case in New Hampshire since it was first reported here in 2013, DHHS said. Anyone with questions can call the State Bureau of Infectious Disease Control at 603-271-4496.
