GLENVIEW, IL – Mosquito net operations are scheduled for Monday night on the north coast, after a week of finding the first West Nile-positive mosquitoes of the year at Winnetka and Northbrook, the North Shore Mosquito Abatement District announced. Targeted spraying and insecticide application is scheduled for parts of Glenview, Golf, Morton Grove, Skokie and Wilmette between 20:00. on the 9th of July and 2am on the 10th of July, weather permitting.

Mosquitoes collected in Northbrook on June 29th tested positive Tuesday, and mosquitoes collected by Winnetka on Monday were tested positive for the virus on Thursday. On July 2, the district tested more than 600 mosquito records and found 15 positive samples of West Nile Virus mosquitoes in Evanston, Glencoe, Glenview, Lincolnwood, Morton Grove, Niles, Northbrook, Northfield and Skokie. Across the country, there were 90 positive batches in 19 counties, according to state health officials.

According to the district, the infection rate among mosquitoes – 1.35 per 1,000 tested – remains above average. The risk of human infection is low, but it increases and human infections usually occur from July to September. Human cases are often not reported because relatively healthy people with West Nile can be asymptomatic, according to the health authorities. People infected with the virus may experience fever, nausea and headaches for weeks.

Last year in Illinois, eight people died among 90 confirmed human cases. A case for one person, a Chicago woman in her sixties, has been reported so far in 2018.

Residents of the district recommend mosquito repellents, wear loose-fitting clothing, and avoid peak mosquito feeding times at dawn and dusk to protect themselves. To report areas that can produce mosquitoes – including ditches, flooded yards, or elsewhere – call 847-446-9434 or report stagnant water or a dead bird online in the North Shore Mosquito Abatement District.
