West Nile Virus Found in Mississauga Mosquitoes

MISSISSAUGA, ON (June 30, 2017) – One mosquito batch collected this week in Mississauga has tested positive for West Nile virus (WNV). The batch was collected near Dixie Road and Lakeshore Road East. This is the first batch to test positive for WNV in Peel in 2017.

"These mosquitoes were collected from one of the 33 traps Peel Public Health maintains and monitors from June to September as part of our annual surveillance program," says Paul Callanan, Director of Health Protection at the Region of Peel. "With this recent confirmation of West Nile activity, we are increasing our efforts in south Mississauga and the surrounding area by looking for breeding sites and re-treating catch basins with larvicide." .

This year has seen very wet weather that creates breeding grounds for mosquitoes. As temperatures rise, so do the chances of contracting WNV from mosquitoes that are more active in hot weather. Peel Public Health is encouraging everyone to make sure they protect themselves and their family before heading outside by using an insect repellent containing DEET.

Residents are asked to help reduce the mosquito population in Peel by removing prime breeding sites on their property.

"The most effective way of eliminating mosquitoes near your home is to remove items that collect water. Turn over old tires or wheelbarrows; empty out pails and plastic wading pools; change the water in your birdbaths often; and put away toys," says Callanan. "If you happen to notice water that has been standing for a week on public property, report it online at peelregion.ca/westnile or by calling Peel Public Health at 905-799-7700."

 Residents can reduce their potential exposure to West Nile virus by:

  • Avoiding areas with high mosquito populations
  • Wearing light-coloured clothing, including long sleeves, pants and a hat, to cover exposed skin, even in their own backyard
  • Using an insect repellent containing DEET and applying it according to the manufacturer's directions
  • Taking extra precaution from dusk to dawn when mosquito activity is higher. If possible, stay indoors

Peel has no confirmed human cases of WNV this season. To date there have been no human WNV cases reported in Ontario.
