Public Health Warning: West Nile Virus Detected in Marseilles, Illinois Mosquito Population

Marseilles, IL [Date of Publication] – Local health officials have issued a public health warning following the confirmation of West Nile Virus (WNV) in a mosquito sample collected within the Marseilles, Illinois area. This discovery underscores the importance of taking preventative measures to protect against mosquito-borne illnesses during the peak mosquito season.

The Illinois Department of Public Health (IDPH) and the LaSalle County Health Department confirmed the presence of WNV after routine mosquito surveillance testing revealed positive results. While this is the first confirmed case in Marseilles this year, the IDPH emphasizes that the risk of WNV transmission remains present throughout the state.

Understanding the Threat of West Nile Virus

West Nile Virus is a mosquito-borne illness that can cause a range of symptoms, from mild fever and headache to more serious neurological complications like encephalitis (brain inflammation) and meningitis (inflammation of the brain and spinal cord). While most people infected with WNV experience mild or no symptoms, a small percentage can develop severe illness requiring hospitalization. Individuals over 60 and those with weakened immune systems are at higher risk of severe complications.

What You Can Do to Protect Yourself

The LaSalle County Health Department urges residents of Marseilles to take proactive steps to reduce their risk of WNV infection:

• Eliminate Standing Water: Mosquitoes breed in standing water. Inspect your property regularly and eliminate any sources of stagnant water, such as birdbaths, clogged gutters, and uncovered containers.
• Use Repellent: When spending time outdoors, especially during dawn and dusk when mosquitoes are most active, use an insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus. Always follow the product label instructions.
• Wear Protective Clothing: Cover exposed skin by wearing long sleeves, long pants, and socks when outdoors, particularly during mosquito-prone times of day.
• Repair Window Screens: Ensure all window and door screens are in good repair to prevent mosquitoes from entering your home.

Community Efforts and Further Information

The LaSalle County Health Department is working diligently to control the mosquito population through larviciding and adulticiding programs. These efforts aim to reduce the number of mosquitoes and minimize the risk of WNV transmission. Residents are encouraged to report any areas with significant mosquito breeding grounds to the local health department.
