Summary
Wisconsin DHS confirmed the season’s first West Nile virus activity after detecting the virus in mosquitoes and birds, with no human cases reported yet.
Mosquito bites are the main transmission route, and officials said prevention is critical because there is no vaccine or specific treatment once someone is infected.
20%-30% DEET or 20% picaridin repellents, limiting outdoor time at dawn and dusk, wearing light-colored clothing, and removing standing water were cited as key steps to cut risk.
25% of infected people may develop West Nile fever, while less than 1% develop severe neuroinvasive illness such as meningitis, encephalitis or acute flaccid paralysis.
