Recent Heat Creates Potential for Increase in West Nile Virus Activity

Mississauga, ON (September 7, 2018) – Peel Public Health reminds residents to be vigilant against being bitten by mosquitos during the heart of West Nile virus (WNV) season.

“Late August and early September has seen exceptionally hot, humid weather. As temperatures rise, so does the chance of contracting WNV from mosquitoes — and we are seeing that with human cases being reported in Peel and across the province, says Dr. Lawrence Loh, Associate Medical Officer of Health, Region of Peel. “Even though it will be getting cooler in the evenings, it is still important to protect against mosquito bites during the fall months until there is a significant frost event,” he continued.

The recent weather patterns reinforce the need for all residents to protect themselves from mosquito bites. Most people who contract the disease will show no symptoms, but 20 per cent will experience mild flu-like symptoms, and about 1 in 150 will develop a more severe form of the disease.

Peel Public Health is encouraging everyone to make sure they protect themselves and their family from mosquito bites by doing the following:
