Mosquitoes have been thick across many portions of the state this summer. And, we went almost the entire summer without a report of the West Nile Virus in Michigan.

But, reports that the state's first cases of the mosquito-borne disease have been reported this month. Four cases, in fact. Two victims are in Montcalm County, one in Oakland County, and a fourth in Macomb County.

The disease has showed up in birds, livestock and wildlife this summer. But, these four instances are the first in humans this year. West Nile is a virus that affects the neurological system.
