Some mosquitoes captured in North York have tested positive for West Nile virus, according to a statement from the city.
The recent test is the first positive result so far this year, Toronto Public Health said in a statement Tuesday afternoon, and should serve as a reminder for the public to avoid mosquitoes.
West Nile virus was first discovered in Toronto in 2001. Last year, the city found 18 West Nile-positive mosquito pools and 12 human cases were reported. No human cases have been reported in Toronto so far this year.
As part of Toronto's West Nile virus mosquito-reduction program, catch basins and other areas of still water are treated every year with larvicide to reduce breeding.
TPH has 43 traps across the city, and submits specimens for laboratory testing every week.
Although the risk of humans becoming infected is low, TPH is urging residents of the city to avoid bites using the following tips:
- Wear light-coloured clothing, long pants, long-sleeved shirts, socks and hats
- Use mosquito repellent approved by Health Canada
- Avoid areas with a large number of mosquitoes, especially during dusk and dawn
- Make sure your home has tight-fitting screens on windows and doors
