New Hampshire state health officials reported a fifth case of Jamestown Canyon Virus (JCV) in an adult from Newport.

The patient was hospitalized with left side weakness, unresponsiveness and multiple seizures. Their condition has not recently improved and they remain hospitalized to date.

“Although JCV is still a rare disease, we are seeing more infections in NH, which is concerning,” said Dr. Benjamin Chan, NH State Epidemiologist. “Similar to other diseases in NH that are spread through mosquito bites, like West Nile Virus and Eastern Equine Encephalitis, infection with JCV can cause a severe neurologic disease. The risk for mosquito-transmitted infections is present from when snow melts in the spring until there is a mosquito killing frost in the fall.”

JCV is a mosquito-borne pathogen that circulates widely in North America primarily between deer and mosquitoes but can also infect humans.

People can be infected and not develop any symptoms, or only develop very mild symptoms for all three mosquito-borne diseases. Early symptoms can include fever, muscle aches, headaches, and fatigue. More serious central nervous system disease, including meningitis or encephalitis can occur with these diseases. If you or someone you know is experiencing symptoms, including fever and headache, contact your local medical provider.
