West Nile Virus Risk Level and Surveillance Results

West Nile virus (WNV) is a mosquito-borne virus that can be transmitted to humans through the bite of an infected mosquito. The main species that carries WNV in Saskatchewan is Culex tarsalis.

Regardless of the West Nile virus risk level for your area, remember there is no such thing as "risk-free". If you get bitten by an infected mosquito, you can contract West Nile or other mosquito-borne viruses.

Take precautions when you are out in areas where mosquitoes are present. Protect yourself by covering up and wearing repellents or reducing the amount of time spent outdoors.  Mosquitoes can be active at any time but are most active in the evening and throughout the night.
