Peel Region confirms first West Nile virus positive mosquitoes for 2023

Residents reminded to protect themselves from mosquito bites and remove any standing water from their property

Brampton, ON - (July 24, 2023) - The season's first West Nile virus positive mosquitoes have been identified in Peel Region. The mosquitoes were collected from a trap in Brampton near the intersection of North Park Drive and Torbram Road.

Peel Public Health monitors West Nile virus activity through 33 mosquito traps across Mississauga, Brampton and Caledon. Mosquitoes from the traps are collected and tested weekly from mid-June to September. Public Health staff also survey public areas for stagnant water that may serve as mosquito breeding sites and treat identified sites with larvicide.

West Nile virus is a mosquito-borne disease passed to humans via the bite of an infected mosquito. Peel Public Health has not confirmed any human cases of West Nile virus to date this year.

Although the risk of acquiring West Nile virus infection is low, Peel Public Health reminds residents there are simple things that you can do to protect against mosquito bites:

Peel residents can also help prevent mosquito bites by removing or draining items on their property that hold stagnant water. Water that is stagnant for more than seven days is an ideal breeding site for mosquitoes. Report stagnant water sites to Peel Public Health at 905-799-7700 (toll-free at 905-584-2216 in Caledon) or online.
