West Nile Virus

West Nile virus is transmitted to humans by a bite from an infected mosquito.  During the summer of 2018, the Health Department and DPW will continue our West Nile surveillance and treat catch basins that have standing water for mosquito larva in the spring.  Treating the catch basins with larvicide prevents mosquito larva from becoming adult mosquitoes.  The treated catch basins are retested after 45 days to determine the effectiveness of the treatment.

The statewide, toll-free DEAD BIRD REPORTING HOTLINE at 1-800-433-1610 has been activated and will remain open through the mosquito season until October 31, 2018.  As in previous years, the Dead Bird Reporting Hotline is available for Wisconsin residents to report sick or dead birds, and to facilitate West Nile virus (WNV) testing of corvids (crows, ravens, blue jays) to monitor WNV activity.  Questions about dead birds and information on safe handling and disposal can be answered by hotline staff. Do no handle dead birds with your hands.
