The city’s first positive test for West Nile Virus (WNV) has been confirmed on Friday by Toronto Public Health.

In a tweet from the agency, it said that a positive mosquito pool test for WNV had been received, but advised that the risk to the public is low.

TPH conducts testing on mosquitos from mid-June to mid-September each year. According to the agency, once a week, 22 mosquito traps are set across the city to collect the insects for identification and testing.

Despite the low chance of infection, TPH says there are a number of steps that can be taken to avoid mosquitoes, those include the following:

  • Wearing light-coloured, long-sleeved shirts and pants when outdoors.
    Apply insect repellent containing DEET or icaridin, following the manufacturer instructions.
  • Take extra care during peak mosquito biting time (dusk and dawn) by using mosquito repellent and wearing protective clothing.
  • Remove standing water from your property, where mosquitoes can breed.
  • Ensure your home has tight-fitting screens on windows and doors.
