Description
Summary:The incidence of West Nile virus (WNv) has waxed and waned in Canada over the past 12 years, but it is unlikely to disappear. Climate change models, which suggest warming temperatures and changing patterns of precipitation, predict an expansion of geographic range for WNv in some regions of Canada, such as the Prairie provinces. Such projected changes in WNv distribution might also be accompanied by genetic changes in the virus and/or the range of bird and insect host species it infects. To address this risk, emphasis should be placed on preventing exposure to infected mosquitoes, conducting high-quality surveillance of WNv and WNv disease, controlling mosquito vectors, and promoting public and professional education.
