The first three human cases of West Nile Virus in Wisconsin this year have been reported in residents of Outagamie, Fond du Lac, and Brown counties. 

In addition, West Nile Virus has also been detected this year in mosquitoes, animals, and healthy blood donors whose blood screened positive for West Nile Virus.

The Department of Health Services say the best way to avoid illnesses spread by mosquitoes is to reduce exposure to mosquitoes and eliminate mosquito breeding sites.
