Wake Up Tri-Counties Sam Rux from OSF Healthcare Talks Mosquitoes and West Nile Virus

Samantha Rux from OSF Healthcare joined Wake Up Tri-Counties to discuss mosquitoes and West Nile Virus. Health officials in Illinois are urging caution as mosquito testing reveals positive results for West Nile Virus in 18 counties, including Henry, Stark, and Bureau. Although no human cases have been reported so far, the risk remains high, particularly for older adults and those with compromised immune systems. The West Nile virus is mainly transmitted by mosquito bites, and past outbreaks in Illinois have been severe. Residents are encouraged to use EPA-approved insect repellent, wear protective clothing outdoors, and regularly remove standing water to prevent mosquito breeding. Early symptoms include high fever and severe headache; seek medical care if these occur.

The West Nile virus, primarily transmitted through mosquito bites, is a growing health concern during the warmer months. While most people experience no symptoms or only mild, flu-like illness, severe cases can lead to dangerous conditions such as encephalitis or meningitis, especially in older adults or those with weakened immune systems. There is no vaccine or specific treatment available. The best defense is prevention: use EPA-approved insect repellents, wear long sleeves and pants outdoors, and eliminate standing water where mosquitoes breed. Awareness of symptoms like high fever, severe headache, or confusion is crucial—seek medical attention if these develop.

Illinois has faced significant challenges with West Nile virus since it was first detected in dead crows in the Chicago area in September 2001. By 2002, the state reported the highest number of human cases and fatalities in the United States, with 884 cases and 64 deaths. The Illinois Department of Public Health uses a comprehensive surveillance system to track infected birds, mosquitoes, horses, and humans. West Nile virus is primarily spread through the bite of infected mosquitoes, with people over 60 most at risk for severe illness. Authorities urge residents to eliminate standing water and use protective measures to reduce risk.
