A dead crow found in Waupaca County two weeks ago has tested positive for the West Nile virus. That according to a report released by the county’s Department of Health and Human Services. It is the first bird that has tested positive for the virus since testing began May 1st. Waupaca County Health Officer Jed Wohlt says the positive test means county residents need to be more vigilant in protecting themselves from mosquito bites. The virus is spread to humans that way. Mosquitoes acquire the virus by feeding on infected birds. About 80 percent of people who get infected with West Nile do not get sick. Those who do usually experience symptoms such as headaches, rash, and fatigue. Less then 1 percent get seriously ill, with high fever, muscle weakness, tremors, and disorientation.
