West Nile virus has been detected again in Simcoe Muskoka – a bird in Barrie and a mosquito pool in New Tecumseth.

To date, no human cases of West Nile virus have been reported in Simcoe Muskoka yet in 2025. However, the health unit is reminding the public that an increase in virus among birds and mosquitoes presents a higher likelihood that the virus can spread to humans. Late summer is prime time for infections.

The Simcoe Muskoka health unit advises to protect yourself from mosquito bites by using repellent, wear light coloured clothing that covers you and stay indoors during dusk and dawn.
