West Nile Virus activity detected in Logan County
[August 01, 2026]
The Illinois Department of Public Health collected a mosquito
batch in the Chestnut, IL area on July 30, 2026 which tested positive
for West Nile Virus (WNV). This is a reminder that WNV is still a
concern throughout Logan County for the remainder of the summer and
fall. West Nile encephalitis is an infection of the brain caused by the
WNV which is transmitted through the bite of an infected mosquito.
The Logan County Department of Public Health would like to remind
everyone that the best way to prevent WNV disease is to reduce the
number of mosquitoes around your home and to use personal protection.
The Logan County Department of Public Health would like to urge you to
practice the following:
• Do reduce your exposure by avoiding being outdoors when
mosquitoes are most active from dusk to dawn. Repair screens with tears
or any other outer openings. Keep windows shut and eliminate areas of
standing water around your property where mosquitoes can breed.

• Do repel mosquitoes from biting when outdoors by wearing
shoes, socks, long pants and a long-sleeved shirt (light-colored
clothing is preferred). Wear repellents that contain DEET, picaridin,
oil of lemon eucalyptus or IR 3535 and use according to the label
instructions.
If you are bitten by a mosquito, there is no reason to be tested for
WNV since illnesses related to mosquito bites are rare. However, if
you develop symptoms such as high fever, confusion, muscle weakness
or severe headache, you should see your doctor.
Remember to play it safe and to continue to take preventative
measures until mosquito activity fully ceases. If you have questions
regarding WNV, you can contact the Logan County Department of Public
Health at 217-735-2317. For additional information regarding the
