According to a Maine Public report, state epidemiologist Dr. Siiri Bennett says it’s unclear whether the virus is more common, or it’s been detected through better testing.

“We just have to be really cautious when there are mosquitoes are around,” says Bennett. “Use the inspect repellant. Cover up. Make sure you are aware of what you can do to prevent bites.”

Jamestown Canyon virus is a relatively rare disease that can be carried by multiple mosquitoes including mosquito species that are present here in Maine. Symptoms of arboviral illnesses include fever and flu-like illness, and can result in encephalitis or meningitis. Jamestown Canyon virus as well as the two more well-known diseases—West Nile virus and Eastern equine encephalitis —are viruses transmitted through the bite of an infected mosquito. They cannot be transmitted from human to human or animal to human.
