马的西尼罗河病毒性脑炎以前在非洲、亚洲和欧洲报告，1999年首次在西半球发生。西尼罗河病毒是一种由鸟类-蚊子循环维持的黄病毒，与美国爆发的人类，马和鸟类的脑炎疾病和死亡有关。马的这种疾病主要表现为不同严重程度的共济失调。虽然相当数量的感染是不明显的，但马的病死率可能超过40%。该病毒已在美国越冬，并对未来疾病的发生构成威胁。
West Nile viral encephalitis in horses, previously reported in Africa, Asia and Europe, occurred for the first time in the Western Hemisphere in 1999. West Nile virus, a flavivirus maintained by a bird-mosquito cycle, was associated with encephalitic illness and deaths in humans, horses and birds in the US outbreak. The disease in horses is manifested primarily by ataxia of variable severity. Although a significant number of infections are inapparent, equine case fatality rates may exceed 40%. The virus has overwintered in the United States, and poses a threat of future disease occurrences.
