MERRILL (WAOW) – A fourth county in central and northern Wisconsin has found a dead bird infected with the mosquito-transmitted West Nile virus.
A crow found July 15 in Lincoln County tested positive for the virus, meaning people need to be more aware of protecting themselves against mosquito bites, Health Department Director Shelley Hersil said Tuesday. The dead bird was found in the Merrill area.
As of Tuesday, dead birds with West Nile virus have also been found in Oneida, Vilas and Wood counties, health officials said.
State and local health officials announced on Monday that the first human case of West Nile virus in Wisconsin this summer was diagnosed in a Dane County resident.
The best way to avoid the disease is to reduce exposure to it and eliminate breeding grounds for mosquitoes, Hersil said in a statement Tuesday.
About 80 percent of people who are infected with the West Nile virus do not get sick, health experts said. Those who do get ill usually experience mild symptoms, such as fever, headache, muscle ache, rash and fatigue, said authorities.
The state Department of Health Services said 57 cases of West Nile virus infections in people were reported last year.
