The West Nile virus (WNV) surveillance program is a component of the Division of Environmental Health which is funded by the Vector Control and Surveillance Grant provided by the Illinois Department of Public Health. 

The Division of Environmental Health conducts surveillance activities by operating gravid traps designed to capture WNV-positive Culex mosquitoes throughout Kankakee County. Surveillance activities begin late spring and continues until late fall. Mosquitoes are collected twice a week and regularly tested for WNV. Past and present WNV surveillance data can be found here

Past and present WNV surveillance data

Kankakee County residents are encouraged to report locations of dead birds. Since West Nile virus, on average, is found in bird populations before it is transmitted to humans, the presence of dead birds can serve as an early indicator for West Nile virus activity. 

However, only report eligible dead birds during the following dates: June 1 through September 30. Eligible birds are those that meet the following criteria: 

1. The bird has been dead for no more than 24 hours.
2. The bird is in good condition. There should be no signs of decomposition (e.g., no strong odor, no bloating, no maggots, eyes are not deflated, etc.) and has not been damaged by scavengers.
3. The bird has not died of causes other than disease. Birds with obvious signs of injury or trauma and birds found on the streets should not be reported. 
4. The species of the bird is eligible for testing; acceptable species include: crows, cardinals, morning doves, blue jays, robins, hawks, and owls.

To report a dead bird, please contact the Division of Environmental Health at: (815) 802-9410.

County Residents can report locations of stagnant water that has been standing for five or more days. Stagnant water is conducive to the breeding of Culex mosquitoes and is considered a nuisance condition in Kankakee County.

To report stagnant water, please contact the Division of Environmental Health at: (815) 802-9410.
