首先从我国鼠疫自然疫源地的活跃程度入手,分析了疫源地动物间鼠疫的流行特点;接着从自然疫源性疾病的角度阐述了鼠疫自然疫源地方面的研究进展,包括疫源地的隐伏状态、鼠疫菌的突变改变了动物间鼠疫的流行状态等。提出在人口密集区域的鼠疫自然疫源地干预措施:通过综合防治手段使相对独立鼠疫自然疫源地→基本稳定控制的鼠疫自然疫源地→长期静息鼠疫自然疫源地→逐步缩小的鼠疫自然疫源地→消除鼠疫自然疫源地的可能。
First of all, starting from the active degree of natural foci of plague in our country, the epidemic characteristics of plague in foci of origin were analyzed. Then, the research progress of the natural foci of plague was expounded from the point of natural foci of disease. Of the hidden state, the mutation of Yersinia pestis has changed the epidemic status of animals and so on. Put forward in the densely populated areas plague natural foci intervention measures: the comprehensive prevention and control means to make the relatively independent plague natural foci → basic and stable control of plague natural foci → long-term resting plague natural foci → gradually reduced plague Natural foci → the possibility of eliminating plague natural foci.
