There have been no reported human cases of West Nile virus in Michigan, but more dead birds carrying the virus have been found in the state.

A crow found recently in Charlevoix County marked the first detection of the disease in the northwestern Lower Peninsula.

A dead crow in Berrien County tested positive for the virus last week, the first in that county.

The virus has been detected in dead crows throughout the Detroit area.

West Nile is transmitted from infected birds to humans by mosquitoes. It has been detected in birds in 24 Michigan counties.

Those counties are: Bay, Berrien, Branch, Charlevoix, Clinton, Genesee, Gratiot, Ingham, Kent, Lapeer, Lenawee, Macomb, Midland, Muskegon, Oakland, Oscoda, Ottawa, Saginaw, St. Clair, Saint Joseph, Shiawassee, Tuscola, Washtenaw, and Wayne.

The virus has been found in 34 states, and five people in Louisiana have died from it.
