West Nile Virus

West Nile virus has become a health concern for Canadians. DUC encourages people to take appropriate precautions to reduce their risk of exposure to mosquito bites.

Wetlands are one of many known mosquito-breeding habitats, and their importance in producing West Nile virus-carrying mosquitoes will vary across the continent and depend on moisture conditions. Wetlands filter drinking water and they provide vital habitat to approximately 600 wildlife species.

West Nile virus makes the conservation of Canada's remaining wetlands even more important. With up to as 70 per cent of our wetlands already gone in settled areas of Canada, we can’t afford to lose more.

*Note: no additonal provinces or states have reported the presence of West Nile virus since 2004.
