West Nile virus is transmitted through the bite of Culex mosquitoes, which pick up the virus by feeding on infected birds.

The Will County Health Department confirmed its first West Nile virus-positive mosquito sample for 2021.

The sample was collected from a health department mosquito trap in Homer Glen on July 23. The presence of West Nile virus was confirmed on Monday, a news release from the health department said.

The health department has 14 mosquito traps in various regions in Will County, the release said.

Last year, the Illinois Department of Public Health IDPH reported 39 human cases of West Nile virus, which included four deaths, the release said. So far, Illinois has reported no human cases of West Nile virus in 2021, the release said.

The Culex mosquito transmits the West Nile virus through its bite after feeding on an infected bird, the release said. The birds that most commonly carry West Nile virus are blue jays, crows and robins.

Anyone older than 60 or anyone who is immunocompromised ha a higher risk of severe illness from the West Nile virus, the release said.

Symptoms of the West Nile virus, which can last several days to several weeks, include fever, nausea, headache and muscle aches, the release said.

The health department recommended these tips for prevention:

• Eliminate excess standing water around your property where Culex mosquitos often breed, such as children’s wading pools, birdbaths and gutters.

• Avoid being outside between dusk and dawn. These peak mosquito periods between dusk and dawn.

• For those who venture out, wear insect repellent containing DEET as well as long sleeves, long pants, and socks and shoes.

If you see a dead bird on your property, contact the Will County Health Department. The bird may need to be tested.
