First mosquito-borne virus of 2022 found in Michigan mosquitoes

Mosquitoes collected in Bay County tested positive for the Jamestown Canyon virus, the Michigan Department of Health and Human Services announced.

These are the first infected mosquito pools detected this year.

Most cases of Jamestown Canyon virus occur from late spring through mid-fall.

Most people do not get sick but initial symptoms can include a fever, headache, and fatigue.

“It only takes one bite from an infected mosquito to cause a severe illness,” said Dr. Natasha Bagdasarian, MDHHS chief medical executive. “We urge Michiganders to take precautions such as using an EPA-registered insect repellent when outdoors, avoiding areas where mosquitoes are present if possible, and wearing clothing to cover arms and legs to prevent bites.”
