１９９８年８～９月，云南省蒙自县红寨乡发生动物间鼠疫流行。共分离到鼠疫菌８株，其中黄胸鼠７株，印鼠客蚤１株。查出反相血凝阳性１８份。流行病学调查、病原学和血清学检验追溯诊断证实腺鼠疫患者６人。调查分析表明；此次鼠疫暴发流行是历史疫区家鼠鼠疫的复燃，该地家鼠密度与印鼠害蚤指数增高及当地居民不良的生活习俗是诱发此次流行的重要原因。

A total of 8 strains of Yersinia pestis were isolated, including 7 Rattus flavipectus and 1 Rattus norvegicus. Detected positive anti-clotting 18 copies. Epidemiological investigations, etiological and serological tests retrospectively confirmed the diagnosis of bubonic plague in 6 patients. The investigation and analysis showed that the outbreak of plague was the resurgence of the domestic plague in the historical epidemic area. The density of domestic rats and the increase of the flea index of rats and rats, as well as the unfavorable living habits of local residents, were the major causes of this epidemic.
