JACKSON COUNTY, IL (KFVS) - Mosquitoes in Jackson County, Illinois are able to do more than just annoy residents, some have been found with the West Nile virus.

Routine testing identified the virus in the insects collected on July 18 in and around Murphysboro.

The virus can be transmitted through a bite from a mosquito with the virus contracted by the insect biting an infected bird.

Symptoms of the virus include fever, nausea, headache and body aches within three to 14 days of the bite. According to the Health Department in Jackson Co., one out of five people infected will have these symptoms.

Serious illnesses like encephalitis and meningitis, with lingering complications and even death, are possible.
