At present, African swine fever (ASF) persists as an enzootic infection both on the African continent and in Europe (Portugal, Spain, and Sardinia). The recent outbreaks of ASF in Belgium and in the Netherlands have again demonstrated the threat of this disease to the swine population in Germany. The main reasons for this threat are the great tenacity of this virus and its stability in meat and meat products together with an immense tourism into these enzootic areas. Epizootiological peculiarities, such as virus replication in ticks and inapparent infections in wild boars are the reason why eradication of the disease has failed so far, especially when pigs are allowed to roam the countryside.
目前，非洲猪瘟（ASF）在非洲大陆和欧洲（葡萄牙、西班牙及撒丁岛）仍作为一种地方流行性传染病持续存在。近期在比利时和荷兰爆发的非洲猪瘟再次表明了这种疾病对德国猪群的威胁。造成这种威胁的主要原因是该病毒具有很强的韧性，在肉类和肉制品中具有稳定性，再加上大量游客前往这些地方流行病区。流行病学特性，如病毒在蜱虫中的复制以及野猪中的隐性感染，是迄今为止根除该疾病失败的原因，特别是当猪可以在乡村自由活动时。
