Peel confirms first probable human case of West Nile virus this year

Mississauga, ON (September 17, 2021) – Peel Public Health has received confirmation of the first probable human case of West Nile virus in a Peel resident this year. West Nile virus is an infection transmitted to people through the bite of an infected mosquito. Peel Public Health reminds all residents to protect themselves from mosquito bites and to remove standing water where WNV-carrying mosquitoes can breed.

While the risk of getting West Nile virus in Peel is low, this case reinforces the need for all residents to protect themselves from mosquito bites when outdoors and to remove mosquito breeding sites from their properties. Mosquitoes will remain active until the first frost.

Dr. Lawrence Loh, Medical Officer of Health, Region of Peel.

West Nile virus symptoms usually develop between two and 14 days after a person is bitten by an infected mosquito. Most people who contract the disease will show no symptoms, and approximately 20 per cent will experience mild flu-like symptoms. In very rare cases (fewer than 1 per cent) the infection can cause more severe symptoms including severe headache or confusion.
