West Nile virus (WNV) infection in horses was first reported in Canada in 2001 and in the province of Saskatchewan in 2002. This paper outlines the surveillance results of WNV in Saskatchewan horses from 2003 to 2005 and describes the usefulness of its inclusion in an integrated surveillance program in Saskatchewan. The number of human and horse cases was highest in 2003, the epidemic year and then substantially lower in 2004 and 2005. Horses provided additive information about WNV activity in rural areas with low human population, however, this required willingness and active participation by veterinarians and horse owners. Vaccination impedes the future use of horses in WNV surveillance for public health or veterinary purposes; however, for zoonoses where no vaccination is available, domestic animals would be useful components for surveillance. Integration of surveillance data from human and animal health provide the benefit of a more complex epidemiological picture that can be used to improve public health.
西尼罗河病毒（WNV）感染马匹的情况于2001年首次在加拿大被报道，2002年在萨斯喀彻温省被报道。本文概述了2003年至2005年萨斯喀彻温省马匹中WNV的监测结果，并描述了将其纳入萨斯喀彻温省综合监测计划的作用。2003年（疫情年）人类和马匹病例数最高，2004年和2005年则大幅下降。马匹提供了关于人口稀少农村地区WNV活动的补充信息，然而，这需要兽医和马主的意愿及积极参与。疫苗接种妨碍了未来将马匹用于公共卫生或兽医目的的WNV监测；然而，对于没有可用疫苗接种的人畜共患病，家畜将是监测的有用组成部分。整合来自人类和动物健康的监测数据可提供更复杂的流行病学情况，有助于改善公共卫生。
