Toronto Public Health has confirmed positive tests for West Nile virus in some mosquitos collected from the city. This marks the first detection of the virus this year following the testing of three mosquito batches. The virus is transmitted to humans through mosquito bites, with symptoms that can appear within two to 14 days. Individuals over 50 or those with weakened immune systems face a higher risk of severe illness. TPH recommends wearing protective clothing, using approved repellents, and taking measures to eliminate standing water.
