Jamestown Canyon Virus Detected in York County
Maine CDC urges precautions to avoid mosquito bites
The Maine Center for Disease Control and Prevention (Maine CDC) announced today that mosquitoes in the York County town of Wells have tested positive for Jamestown Canyon virus (JCV).
This is the first mosquito pool -- a group of one to 50 mosquitoes collected as part of regular testing -- from Maine to test positive for JCV since 2019. There are currently no known human cases of JCV or any other locally-acquired mosquito-borne illnesses in Maine this year.
