The known distribution of African swine fever (ASF) virus in Africa is reviewed in relation to the distributions of its free-living hosts as are the infection rates of these species in different localities in southern Africa. Mechanisms by which ASF virus is maintained in its sylvatic state and ways in which the infection may enter domestic pig populations are discussed.
本文回顾了非洲猪瘟（ASF）病毒在非洲的已知分布情况，及其与自由生活宿主分布的关系，以及这些物种在南部非洲不同地区的感染率。文中还讨论了ASF病毒在其自然疫源状态下得以维持的机制，以及该感染可能进入家猪群体的途径。
