An outbreak of equine sarcoid occurred in a population of Cape mountain zebra (Equus zebra zebra) at the Gariep Nature Reserve located in the southern Free State Province of South Africa in 1996. The course of the outbreak during 1996 to 2003 is described. During this period the average population size was 69 animals. Initially (1996) all affected animals were removed from the population. New cases continued to manifest and the incidence varied between 4.6% and 17.6%. Prevalence reached 24.7% in 2002. No sexual predilection was noticed in the 39 recorded cases. Of the affected individuals, 64% had a single lesion and no animal had more than 4 lesions. In males, the majority of lesions occurred in the inguinal area (55.17%), whereas in females they mostly occurred on the head and neck (41.38%). Lesions can increase 260% in size annually and may impede movement.
1996年，南非自由邦省南部的加里普自然保护区的一群开普山斑马（Equus zebra zebra）爆发了马肉瘤。本文描述了1996年至2003年期间疫情的发展过程。在此期间，平均种群数量为69只动物。最初（1996年），所有受感染的动物都被从种群中移除。新病例持续出现，发病率在4.6%至17.6%之间波动。2002年患病率达到24.7%。在记录的39例病例中未发现性别偏好。在受影响的个体中，64%有单个病变，没有动物有超过4个病变。在雄性中，大多数病变发生在腹股沟区域（55.17%），而在雌性中，病变大多发生在头部和颈部（41.38%）。病变每年可增大260%，并可能阻碍行动。
