Illinois has reported its first human case of West Nile Virus (WNV) for 2025, according to the Wayne County Health Department. The individual was hospitalized due to complications from the virus but is now recovering at home.
According to the Centers for Disease Control and Prevention (CDC), WNV is transmitted through mosquito bites, particularly those of infected Culex mosquitoes. Most people show no symptoms, but severe cases can cause neurological conditions like meningitis, encephalitis, paralysis, or death.
The elderly and those with weakened immune systems are at highest risk for serious illness. So far in 2025, 19 counties have reported WNV activity, including Wayne County.
Illinoisans are advised to take precautions against mosquito bites, particularly during peak hours (dusk to dawn). The Illinois Department of Public Health recommends reducing exposure by fixing screens and eliminating standing water around homes.
Residents can also repel mosquitoes using EPA-registered insect repellents or wear protective clothing. Additionally, reporting potential mosquito breeding sites to local authorities can help prevent the spread of the virus.
The state is providing $2.8 million in funding for mosquito control efforts across the state. For more information on WNV, visit the Illinois Department of Public Health’s website at: www.idph.state.il.us/envhealth/wnv.htm
