Mosquitoes In Winnetka And Glencoe Test Positive For West Nile Virus

WINNETKA, IL — For the first time this year, West Nile virus positive mosquitoes were collected from traps in Glencoe and Winnetka, the North Shore Mosquito Abatement District announced Thursday.

Batches of mosquitoes collected on Wednesday tested positive in the NSMAD lab on Thursday. This week, West Nile positive mosquitoes have also been found in Evanston, Glenview, Golf, Kenilworth, Lincolnwood, Niles, Northbrook, Northfield, Skokie, Wilmette, Deerfield and Highland Park.

"While the risk of being infected with West Nile virus is low at this time, it is increasing. The NSMAD recommends that residents take personal protection measures to minimize mosquito bites," officials said in a statement.

Culex pipiens mosquitoes are the primary carriers of West Nile virus and they typically breed in stagnant water. Items like buckets, gutters, plant containers and kiddie pools can be prime areas for these insects to lay their eggs.

To minimize mosquito bites, resident should:

• use an EPA registered insect repellent
• wear loose fitting clothing and avoiding peak mosquito feeding times during the hours around dawn and dusk
• examine their property and eliminate any items that can hold water, particularly smaller items that may be easily overlooked.

If a person is infected with West Nile virus, they can develop a fever or a mild headache. Severe symptoms can include a rapid onset of a high fever with head and body aches, disorientation, tremors and convulsions.

According to the North Shore Mosquito Abatement District, in the most severe cases, paralysis or death may occur. Those who are 50 years of age or older are at the highest risk for serious illness. Symptoms typically occur within three to 14 days after the bite from an infected mosquito.
