The DuPage County Health Department is reporting its first positive test for West Nile virus from insects caught in a mosquito trap in southwest suburban Lemont.
The mosquitoes that tested positive were collected July 6 and tested July 7, the health department said Friday. Although most of Lemont is in Cook County, the trap was in a small area of the suburb in DuPage County.
The wet and cool spring the county experienced delayed the development of the mosquitoes that spread the virus. Hotter temperatures in recent days are more conducive to the spread of West Nile, which explains the positive test, the release said.
No human cases of West Nile virus have been reported in DuPage County so far this year.
West Nile Virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Most people with the virus have no clinical symptoms of illness, but some may become ill three to 15 days after the bite of an infected mosquito.
