Illinois health officials have confirmed the first human case of West Nile virus in Southern Illinois this year. The affected individual required hospitalization after developing complications related to the virus. At this time, positive samples have been detected in mosquitoes, birds, horses, and humans across 19 counties. Although West Nile often causes no symptoms, experts warn that severe illness is possible, particularly for those with compromised immune systems or underlying health issues. Residents are advised to use insect repellent, wear long sleeves outdoors, and remove standing water to reduce the risk of mosquito bites as the season continues.
“The fact that we are seeing the first human case of West Nile virus so early in the season serves as a timely reminder – especially for seniors and those with weakened immune systems – to protect yourself from illnesses caused by mosquito bites,” said IDPH Director Dr. Sameer Vohra. “I encourage all Illinoisans to ‘Fight the Bite’ and take precautions to protect themselves and their loved ones.”
- REDUCE – make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings. Try to keep doors and windows shut.
- Eliminate, or refresh each week, all sources of standing water where mosquitoes can breed, including water in bird baths, ponds, flowerpots, wading pools, old tires, and any other containers.
- REPEL – when outdoors, wear shoes and socks, long pants and a light-colored, long-sleeved shirt, and apply an EPA-registered insect repellent that contains DEET, picaridin, oil of lemon eucalyptus, IR 3535, para-menthane-diol (PMD), or 2-undecanone according to label instructions. Consult a physician before using repellents on infants.
- REPORT – report locations where you see water sitting stagnant for more than a week, such as roadside ditches, flooded yards, and similar locations that may produce mosquitoes. The local health department or city government may be able to add larvicide to the water, which will kill any mosquito larvae.
