How to Protect Yourself From West Nile Virus
The DuPage County Health Department (DCHD) confirmed a positive test for West Nile virus in mosquitoes collected from a trap in Warrenville. This is the fifth positive test from this trap this season.
• There are no human cases in Warrenville at this time.
• DCHD has confirmed the first human death related to West Nile virus (WNV) in DuPage County for 2025. There have been 11 human WNV cases reported to date in DuPage County in 2025.
• This means the virus is active in our area, and it’s important to take steps to avoid mosquito bites.
Protect yourself and your family:
• Use EPA-registered insect repellent
• Avoid being outside at dawn and dusk
• Wear long sleeves, pants, socks, and shoes when outdoors
• Make sure doors and windows are closed tightly at night
• Dump out standing water around your home (even small amounts in flower pots or gutters)
• Report standing water that doesn't drain within a week to the Illinois Department of Public Health
