Two people in Wisconsin have contracted West Nile Virus, according to the State Department of Health Services.
The department said one case has been reported in Oconto County, and the other in Fond du Lac County.
They are the first confirmed cases of human infection this year.
Also, a dead crow found in Kenosha County tested positive for West Nile Virus.
The virus is spread to humans through bites from infected mosquitos.
Mosquitoes acquire the virus by feeding on infected birds.
Last year, 13 cases of West Nile were reported among Wisconsin residents.
