With the first frost approaching, the Will County Health Department's Environmental Division continues to check their mosquito traps for positive West Nile Virus samples.
So far in 2017, the Health Department has tested 190 mosquito samples, with 41 of them showing positive signs of West Nile Virus. The Health Department traps producing the most WNV-positive samples thus far have been Frankfort (6), Mokena (5), Bolingbrook-Central Park (5), and Lockport (5).
All in all, including mosquito samples taken in by Will County municipalities, there have been 65 WNV-positive samples during the 2017 mosquito season.
The Will County Health Department operates a total of 12 mosquito traps. West Nile Virus is passed on to humans when they are bitten by a Culex mosquito that has bitten an infected bird.
Will County residents are advised, especially now that cooler weather makes it much easier, to wear long sleeves and long pants during peak mosquito hours between dusk and dawn, as well as to use insect repellent containing DEET.
