The Will County Health Department Environmental Health Division is reporting five new positive mosquito samples that have tested positive for West Nile Virus. This brings to a total of 17 positive samples out of the 131 that have been collected so far this mosquito season.
The new positive samples were collected earlier this month from the traps in Joliet near the Will County Health Department campus and Sunny Hill Nursing Home, as well as from Frankfort and Lockport.
The Health Department operates 12 mosquito traps. West Nile Virus is passed on to humans when they are bitten by a Culex mosquito who has bitten an infected bird. So far this year, the Health Department has tested four birds; a hawk, two robins, and a chickadee; with three of them having tested negative for WNV. The test results on the chickadee are pending.
Statewide, 41 of Illinois' 102 counties have had a mosquito batch test positive for WNV this year. There have been two human cases; one in Will County and one in DuPage County.
Will County residents are advised to wear long sleeves and long pants during peak mosquito hours between dusk and dawn; and to use insect repellent containing DEET.
