The Centers for Disease Control and Prevention (CDC) recently confirmed Illinois’ first human case of West Nile virus (WNV) in 2025. An individual from Southern Illinois was hospitalized due to complications of the infection. This case underscores the importance of avoiding mosquito bites. WNV can pose elevated health risks for individuals with weakened immune systems and those over 65. According to the Illinois Department of Public Health (IDPH), WNV has already been confirmed in 19 counties, including Clinton and Christian in Central Illinois. The Moultrie County Health Department (MCHD) urges area residents to prevent mosquito bites and reduce their risk of West Nile virus (WNV).
