The virus spreads between birds and some species of mosquitoes and can be transmitted to humans bitten by an infected mosquito.

"During the late summer and early fall, people may feel that the risk of being bitten by mosquitoes is reduced. However, mosquitoes continue to be active, and people need to take precautions to protect themselves from the virus," the SMDHU stated.

Last week, the health unit urged residents to take precautions after the virus was detected in mosquitoes collected from a trap in Alliston.

Additionally, the health unit confirmed mosquitoes tested positive for West Nile in Barrie during two separate batch tests in August.

While many people bitten by infected mosquitoes will not show symptoms, the virus can sometimes lead to serious illness.

Typical symptoms include fever, muscle weakness, stiff neck, confusion, severe headache, and sudden sensitivity to light, and very rarely, can cause severe neurological issues.

To lower the chances of mosquito bites, the health unit advises using approved mosquito repellents and adhering to the instructions provided by the manufacturer.

Residents should also wear light-coloured, long-sleeved shirts and pants, particularly in areas where mosquitoes are more prevalent.

Health officials recommend staying indoors during peak mosquito activity, which usually occurs around dusk and dawn.
