IDPH Reports First Illinois West Nile Virus Death of 2023
CHICAGO – The Illinois Department of Public Health (IDPH) announced the first Illinois human West Nile virus (WNV)-related death in 2023. Testing by CDC confirmed the case was WNV-related. The individual, who was in their 90’s and lived in suburban Cook County, had an onset of symptoms of WNV in early August and died soon after. IDPH is also reporting 11 non-fatal cases of WNV confirmed to date this year. “We are sad to report the first death of the year from West Nile virus in Illinois,” said IDPH Director Dr. Sameer Vohra . “This death and the 11 additional cases are a stark reminder that West Nile virus poses a serious risk, especially to older people and those with weakened immune systems. While the weather is warm and mosquitoes are breeding, we should all take precautions to ‘Fight the Bite’. Please protect yourself and your loved ones by reducing exposures, repelling insects with clothing and repellants, and reporting locations at
