West Nile Virus

West Nile virus is spread to people by the bite of a mosquito infected with the virus. Mosquitoes get infected with it by feeding on infected birds and can then transmit the virus to other animals, birds, and humans. These infections generally occur during warm weather months when mosquitoes are active.


Usual symptoms include fever, headache, body aches, swollen glands or a skin rash on the chest, stomach, and back. In rare cases, it can cause severe disease. Not everyone who is infected will have symptoms.

Public Health assists the Wisconsin Department of Health Services in monitoring for dead birds during the summer months which can be an indicator of the West Nile virus in the local mosquito population.

Dead Bird Reporting

To report a dead bird call the Dead Bird Reporting Hotline at 800-433-1610.

Reduce Mosquito Population

View a few tips to help to reduce the mosquito population:

  • Change the water in pet dishes and replace the water in birdbaths weekly
  • Drill holes in tire swings so water drains out
  • Empty standing water from flowerpots, buckets, and barrels
  • Keep children's wading pools empty and on their sides when they aren't being used
