The maintenance of a virus depends on a number of factors, including the duration of infectivity and the size of the available host population. In this work, foot-and-mouth disease virus was shown to persist in individual African buffalo (Syncerus caffer) for up to at least five years; thus, the duration of infectivity is more than adequate to cover the normal periods between calving peaks. In a small isolated free-living population which varied from 30 to 100 buffalo, two immunological types of foot-and-mouth disease virus were maintained for at least 24 years and through several generations.
病毒的存续取决于多种因素，包括感染性持续时间和可用宿主种群的规模。在这项研究中，口蹄疫病毒在个体非洲水牛（非洲野水牛）中持续存在至少五年；因此，感染性持续时间足以覆盖产犊高峰期之间的正常间隔期。在一个由30至100头水牛组成的小型孤立自由生活种群中，两种免疫类型的口蹄疫病毒持续存在了至少24年，并历经了几代。
