West Nile virus has been detected in mosquito pools in Markham, marking the first confirmed cases of the virus in York Region for the current season. According to York Region Public Health, the infected mosquitoes were trapped near Warden Avenue and Highway 7 East, as well as near Kennedy Road and 16th Avenue, prompting health officials to advise residents on preventative measures.
Understanding West Nile Virus Risks in Urban Environments
West Nile virus is a mosquito-borne illness that can cause infections in humans. The virus is primarily transmitted through the bite of an infected mosquito, which often breeds in stagnant water sources found in residential areas.
York Region Public Health monitors these populations through a seasonal control program. This initiative includes the application of larvicides to catch basins and public water sources, along with weekly mosquito trapping and testing.

How to Prevent Mosquito Bites at Home
Reducing exposure to mosquito bites is the most effective way to avoid infection. York Region Public Health suggests several specific actions for residents:
- Eliminate Standing Water: Regularly empty bird baths, flowerpots, and pool covers. Ensure eavestroughs are clear of debris to prevent water pooling.
- Dress for Protection: When spending time outdoors, particularly at dusk or dawn, wear light-coloured, long-sleeved clothing and long pants.
- Use Proven Repellents: Apply insect repellent containing DEET or icaridin. Always follow the manufacturer’s label directions for safe and effective use.
- Home Maintenance: Check window and door screens for tears and ensure they fit tightly to keep mosquitoes out of living spaces.
Future Trends in Mosquito Control
By investigating human cases alongside routine environmental testing, health authorities aim to create a more responsive barrier against vector-borne diseases.
