The Fond du Lac County Public Health Department says a dead crow found by a Fond du Lac resident has tested positive for the West Nile virus. This is the first bird that has tested positive for the virus in Fond du Lac County since surveillance began May 1st. West Nile is spread to humans through the bite of an infected mosquito. Mosquitos acquire the virus by feeding on infected birds. Steps to reduce your risk include limiting time spent outside at dawn and dusk when mosquitoes are most active and applying insect repellent.
