West Nile virus encephalomyelitis was diagnosed in 28 horses presented to the Ontario Veterinary College Veterinary Teaching Hospital between August 20 and October 15, 2002. The age range of affected horses was 5 months to 20 years (mean 6.9 years, median 6 years). Clinical signs were highly variable. Duration of hospitalization ranged from < 1 to 12 days (mean 5 days, median 5.4 days). Overall, 16 of the 28 (57%) horses were discharged and, of the 14 from which follow-up information was available, 13 (93%) were reported to be clinically normal 4 to 6 weeks following discharge, while the other horse had markedly improved. This pathogen is emerging as an important cause of neurological disease in Canada.
2002年8月20日至10月15日期间，安大略兽医学院兽医教学医院收治了28匹被诊断患有西尼罗河病毒脑脊髓炎的马匹。受影响马匹的年龄范围为5个月至20岁（平均6.9岁，中位数6岁）。临床症状差异很大。住院时间从不到1天至12天不等（平均5天，中位数5.4天）。总体而言，28匹马中有16匹（57%）出院，在可获得随访信息的14匹马中，13匹（93%）在出院后4至6周临床症状恢复正常，另一匹马也有明显改善。这种病原体正在成为加拿大神经系统疾病的一个重要病因。
