In spite of the eradication of Aujeszky's disease in Denmark a single outbreak was recorded in December 1988 and another severe epizootic took place during the winter and spring of 1989/90. The epizootic occurred in nearly the same areas as the preceding epizootic during the winter of 1987/88. Identification of the strains of virus involved eliminated the possibility that the latest epizootic was due to the persistence of virus in the pig population. Furthermore, as during the preceding epizootic, initial recordings of the new strains were found to coincide with periods with southerly winds. It was concluded from circumstantial evidence that the concurrent introductions of virus to several farms played a major role during the epizootic.
尽管丹麦已根除奥耶斯基氏病，但1988年12月仍记录到一次疫情爆发，1989/90年冬春季节又发生了一次严重的动物流行病。此次动物流行病发生的地区与1987/88年冬季上次动物流行病几乎相同。对所涉病毒株的鉴定排除了最新疫情是由于病毒在猪群中持续存在的可能性。此外，与上次动物流行病期间一样，发现新毒株的最初记录与南风时期相吻合。根据间接证据得出结论，病毒同时传入多个农场在此次动物流行病中起了主要作用。
