ST. CHARLES – West Nile virus has been found in a sample of mosquitoes in St. Charles, according to a news release from the city.
The city’s mosquito abatement vendor, Clarke Environmental, collected the sample of mosquitoes.
The company will conduct a citywide spray for mosquito abatement today at dusk. It’s the first confirmation this year of the virus in St. Charles, according to the release.
The first human case of West Nile in Illinois this year surfaced in McHenry County earlier this week.
Mosquitoes carrying the virus have been found in traps in or near Batavia, Aurora, Montgomery, Algonquin and most recently in Elgin.
In addition to mosquitoes, three birds – two in Batavia and one in Aurora – also have tested positive for the virus.
Last year, health officials found 13 human cases of West Nile virus.
Although only about two out of every 10 people bitten by an infected mosquito show symptoms of the virus, it can be severe or even deadly, especially for those older than 50.
Symptoms typically appear three to 14 days after a bite from an infected mosquito and can include fever, headache and body ache. In severe cases, it can cause encephalitis and meningitis.
