West Nile Virus Detected in Mississauga Mosquitoes

Increased Activity Prompts Public Health Advisory

Peel Public Health has confirmed the presence of West Nile virus in mosquitoes collected in Mississauga, raising concerns as summer progresses. The virus, transmissible to humans through mosquito bites, was found in insects from two locations during the week of July 20.

Virus Found in Multiple Traps

Mosquitoes testing positive for the virus were identified in traps situated near the intersection of Dixie Road and Bloor Street, and in the vicinity of Eglinton Avenue West and Ninth Line. This follows an earlier detection the week of July 13 near Derry and Airport roads, a region bordering Brampton and Etobicoke.

Understanding West Nile Virus Risks

West Nile virus typically causes flu-like symptoms, but in some cases, it can lead to severe neurological complications. The City of Mississauga emphasizes that there is no human vaccine or specific treatment, making preventative measures crucial. Elderly individuals and those with compromised immune systems face a higher risk of serious illness.

Public Health Urges Prevention

City officials stress that minimizing exposure is the most effective way to combat the virus. Mosquitoes carrying West Nile virus are most active during dawn and dusk. Residents are advised to limit outdoor activities during these peak hours or stay indoors if possible.

Recommended Protective Measures

The public health department recommends using effective insect repellents containing DEET or icaridin when outdoors. Wearing protective clothing, such as long sleeves, pants, socks, and a hat, is also highly effective, particularly during dawn and dusk.

Ensuring window and door screens are intact and properly fitted is important to prevent mosquito entry. Additionally, it’s advised to store water-collecting items indoors or covered and to repair any leaking outdoor hoses or faucets to eliminate standing water sources.

Reporting Stagnant Water

Residents who notice persistent standing water in catch basins, ditches, or other public spaces are encouraged to report it to Peel Public Health. Contact can be made by calling 905-799-7700 or the toll-free line at 1-888-919-7800, or via their online portal.

According to the latest data from the Public Health Agency of Canada, there were 1,264 human cases of West Nile virus reported in Canada in 2023, with 55 associated deaths, highlighting the ongoing public health concern (Public Health Agency of Canada).
