(SKOKIE) A batch of mosquitoes collected last week in north suburban Skokie tested positive for West Nile virus.
No human cases of the disease have been reported, according to the Skokie Health Department.
The year’s first mosquito batches to test positive in northern Illinois were collected on May 21 in Oak Lawn and May 26 in Evergreen Park, according to the Illinois Department of Public Health.
West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Common symptoms include fever, nausea, headache and muscle aches, the health department said.
Most people infected will not show any symptoms, but in rare cases patients can be come severely ill or die. Those over 50 and people with compromised immune systems are at higher risk for severe illness.
To avoid West Nile, residents should limit time outside between dusk and dawn, when mosquitoes are most active. Eliminate sources of standing water, and wear long sleeves, pants and mosquito repellent when outside, health officials recommend.
