Public Health collects information on dead crows and blue jays to measure the impact of WNV on the bird population from year to year. At this time, this is our best measure of the level of this disease in Madison and Dane County and helps the Department determine the risk of humans to become ill with WNV from May through October.
Dane County residents who find a sick or dead crow or blue jay should call 1-800-433-1610 to report the bird.
In Dane County, Animal Services Officers will be picking up some sick blue jays and crows and submitting them for WNV testing. Testing for WNV in sick crows and blue jays ends after one bird tests positive for WNV.
AS OF MAY 1 2014,
SICK OR DEAD CROWS AND BLUE JAYS
CAN BE SUBMITTED FOR WNV TESTING.
If you wish to submit a dead bird for testing, please do the following:
- Double bag the bird and place on ice or freeze as soon as possible.
- Transport the bird to our office at 2701 International Ln Rm 204, Madison WI 53704.
- The bird should be intact and not showing signs of decay.
Public Health staff also collect and monitor information on WNV infection in humans throughout the season. Infections in humans are monitored through lab testing and reports from healthcare providers.
Adult mosquito traps are placed in locations around the metropolitan area to provide information on mosquito activity in the area. Some of these mosquitoes are also tested for WNV.
