West Nile Virus reported in Milwaukee and Lafayette Counties

The first West Nile Virus human case this year has been confirmed in Barron County, the Wisconsin Department of Health Services reported Monday afternoon. DHS reported mosquitoes collected from Milwaukee and Lafayette counties have tested positive for West Nile Virus. The West Nile virus poses a risk to all Wisconsinites, but people who have weakened immune systems are at higher risk for serious illness.  This virus spreads through the bite of an infected mosquito. Mosquitoes get WNV by feeding on infected birds, and the virus does not spread from person to person, animal to animal, or animal to person. The condition of the affected person is unknown.
