内蒙古扎鲁特旗低山丘陵区鼠疫疫源地是1985年发现的,以达乌尔黄鼠(以下简称黄鼠)为主要储存宿主,松江黄鼠蚤为主要传播媒介的黄鼠鼠疫自然疫源地,是松辽平原达乌达黄鼠鼠疫疫源地的组成部分,但又具有相对独立性,有其自身的流行特点。该疫源地包括扎鲁特旗西部6个苏木(乡、镇)和阿鲁科尔沁旗5个苏木(乡、镇)疫源面积2500km~2。经过1985～1991年的流行病学调查和反复的疫区处理,加之土地开发利用和草牧场沙化,使宿主赖以生存的自然环境有了很大改观,黄鼠数量明显减少,动物鼠疫的流行范围明显缩小,流行强度明显减弱。
The plague origin in the hilly area of Zhalute Banner in Inner Mongolia was discovered in 1985 with the Daheurotus cinnabarinus as the main storage host and the Salmonella dahurica as the main vector of natural plague origin of the plague, It is an integral part of the plague foci of Da Huangda in the Songliao Plain, but it is relatively independent and has its own epidemic characteristics. The foci include 5 hematoxylin (townships) in the western part of Zhalute Banner and 5 hematoxylin (townships and towns) in Aru’erqin Banner with an area of 2500km ~ 2. After 1985-1991 epidemiological survey and repeated treatment of the affected area, combined with land development and utilization and pasture desertification, the natural environment for the host to survive has been greatly improved, the number of yellow rat decreased, the prevalence of animal plague The range was significantly reduced, the intensity of the epidemic significantly weakened.
