FOR IMMEDIATE RELEASE: 
July 29, 2026 | 4:00 pm | Windsor and Essex County 

The Windsor-Essex County Health Unit (WECHU) has been notified that a dead crow found in the City of Windsor tested positive for West Nile virus (WNV). This follows the recent detection of a second WNV-positive mosquito pool in Windsor and Essex. 

No human cases of WNV have been identified in Windsor-Essex County (WEC). However, the positive bird and mosquito pools indicate that the virus is present in the local environment. Residents are encouraged to take precautions against mosquito bites.

"The identification of West Nile virus in both mosquitoes and a local bird confirms that the virus is circulating in our community," said Dr. Mehdi Aloosh, Medical Officer of Health. "Residents can significantly reduce their risk by preventing mosquito bites and removing standing water around their homes."

West Nile virus is spread to humans through the bite of an infected mosquito. The risk of infection is highest during the summer and early fall months when mosquitoes are most active. 

Most people infected with WNV do not become ill. Those who develop symptoms may experience fever, headache, body aches, fatigue, nausea, or vomiting. In rare cases, WNV can cause serious neurological illness, including inflammation of the brain or spinal cord.

Residents can reduce their risk of WNV and other mosquito-borne illnesses by:

• Using insect repellents that contain DEET, Icaridin, or other approved ingredients on clothing as well as exposed skin. Always read and follow label directions.
• Wearing long-sleeved shirts, long pants, and a hat when outdoors. Light-coloured clothing is best, as mosquitoes tend to be attracted to dark colours.
• Limiting outdoor activities at dawn and dusk, when mosquitoes are most active. 
• Removing any standing water in places such bird baths, buckets, old tires, pet water dishes, and gutters around your property to prevent mosquito breeding.
• Make sure window and door screens fit and have no holes.
• Reporting standing water observed in the community by contacting 311 or local municipal by-law enforcement.

If you experience sudden onset of any symptoms listed above, contact your health care provider or seek medical attention immediately. While there is no treatment or vaccine for WNV, symptoms can be managed.

Residents who find a dead bird can report it to the Canadian Wildlife Health Cooperative at 1-866-673-4781. Do not touch dead birds with bare hands, keep pets away from them, and use gloves or a plastic bag if handling is necessary.

The WECHU continues routine mosquito surveillance and monitoring activities throughout the region. For more information about West Nile virus and how to protect yourself, visit the WECHU's WNV page.
