CONCORD, N.H. (AP) — An adult in Loudon, New Hampshire, has tested positive for the Jamestown Canyon virus, the first case of the mosquito-borne disease in the state this year, health officials said.
The virus is transmitted by the bite of an infected mosquito. There are no vaccines for it and treatment consists of supportive care.
The person was hospitalized for neurological symptoms, and has since been discharged and is recovering at home, health officials said Thursday.
This is New Hampshire’s tenth case of the virus since the first report of the disease in the state in 2013. Many illnesses caused by it are mild, but moderate-to-severe central nervous system involvement requiring hospitalization have been reported, including fatal infections.
Early symptoms can include flu-like illness including fever, muscle aches, headaches, and fatigue.
The infection risk level for Loudon will be increased to high, and moderate in the surrounding towns of Gilmanton, Chichester, Canterbury, Barnstead, Pembroke, Pittsfield, Concord, Northfield, and Belmont.
