The Illinois Department of Public Health has issued a warning following the detection of West Nile Virus in mosquitoes across Winnebago County, along with Whiteside and 11 other counties. This announcement comes as part of the department’s proactive measures to mitigate the spread of the virus, especially in light of an early appearance this year likely due to a mild winter and spring.
West Nile Virus is a potentially serious illness transmitted through mosquito bites. While most people infected show no symptoms, around 20% may develop fever, headache, body aches, vomiting, diarrhea, or rash. In rare cases, approximately 1 in 150 people may experience severe symptoms, including neurological issues that can be fatal, according to the Centers for Disease Control and Prevention (CDC).
Dr. Sameer Vohra, Director of IDPH, emphasized the vulnerability of Illinois seniors and individuals with weakened immune systems to the virus. He urged residents to adopt preventive measures such as reducing exposure to mosquitoes, using insect repellent containing DEET or other approved ingredients, and eliminating standing water where mosquitoes breed.
Current Spread and Recommendations
As of 2024, West Nile Virus has been confirmed in multiple counties including Champaign, Cook, Douglas, Fulton, Kane, Hancock, LaSalle, Morgan, Washington, Whiteside, Williamson, Winnebago, and Woodford. The IDPH stresses the importance of following the “3 R’s” to minimize the risk of infection:
- REDUCE: Ensure doors and windows have intact screens and eliminate standing water in containers such as bird baths and flowerpots.
- REPEL: Wear protective clothing and apply EPA-registered insect repellents when outdoors. Consult a physician before using repellents on infants.
- REPORT: Inform local authorities about stagnant water in public areas to facilitate larvicide application, which kills mosquito larvae and prevents further breeding.
