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 always some risk of WNV transmission except after a wide-spread hard frost and throughout winter. 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.
