非洲野牛被引入津巴布韦东南部的野生动物保护区，以提高保护区的经济可行性，这主要是基于生态旅游。水牛感染了口蹄疫病毒的SAT血清型（SAT-1、SAT-2和SAT-3），为了隔离农田，防止口蹄疫向邻近家畜传播，农田周围设置了1.8 m高的双层围栏系统。这样做的目的是防止野生动物和家畜越过围栏。然而，在引进野牛两年后，口蹄疫发生在保护区外的牛身上。通过血清学和分子诊断测试，流行病学调查显示，最有可能的是羚羊（黑斑羚或羚羊）通过与保护区内的水牛群接触而感染，跳过围栏并将病毒传播给了牛。
African buffalo were introduced into a wildlife conservancy in the southeast of Zimbabwe in an effort to increase the conservancy's economic viability, which is primarily based on eco-tourism. The buffalo were infected with SAT serotypes (SAT-1, SAT-2 and SAT-3) of foot and mouth disease (FMD) virus, and in order to isolate the conservancy and prevent the transmission of FMD to adjacent populations of domestic livestock, the conservancy was surrounded by a double-fence system, 1.8 m in height. The intention was to prevent the movement of both wildlife and domestic animals across the perimeter. However, two years after the buffalo were introduced, FMD occurred in cattle farmed just outside of the conservancy. Using serological and molecular diagnostic tests, epidemiological investigations showed that it was most likely that antelope (impala or kudu), infected through contact with the buffalo herd within the conservancy, had jumped over the fence and transmitted the virus to the cattle.
