The second half of September brought about three more mosquito samples being tested as positive for West Nile Virus by the Environmental Division of the Will County Health Department.
With the possibility of a first frost in October, the Health Department now has a total of 50 samples testing positive for West Nile Virus in 2017, out of the 216 tested samples.
The Will County Health Department, which operates 12 mosquito traps; collected positive samples during the month of September from the Manhattan trap on 9/14, from the Bolingbrook Trout Fish Farm trap on 9/15, and from the Plainfield trap on 9/25.
So far this year there continues to have been only one human death due to West Nile Virus, in the Kankakee area. In 2016, there were six human West Nile Virus deaths throughout the state of Illinois.
West Nile Virus is passed on to humans when they are bitten by a Culex mosquito that has bitten an infected bird. The Will County Health Department has tested five birds this year, none of which were West Nile Virus positive.
Will County residents continue to be advised to wear long sleeves and long pants during peak mosquito hours between dusk and dawn, as well as to use insect repellent containing DEET.
