目的分析1981~2007年宁夏鼠疫监测资料及鼠疫流行病学特征,提出预防措施和控制对策。方法运用流行病学方法和医学统计方法进行统计、分析与评价。结果27年间,阿拉善黄鼠疫源地宿主密度为0.31~1.80只/公顷,染蚤率为28.07%~66.47%,蚤指数为0.88~3.15,有8个年次监测到鼠间鼠疫的局部流行;长爪沙鼠疫源地宿主密度为0.10~5.90只/公顷,染蚤率为9.57%~57.34%,蚤指数为0.07~1.44,有9个年次监测到动物鼠疫流行。结论宁夏动物鼠疫流行呈周期性、间断性发生。坚持以鼠疫监测、宣传教育、灭鼠灭蚤、区域联防为主的综合防治是预防控制鼠疫的主要措施。
Objective To analyze epidemiological characteristics of plague in Ningxia from 1981 to 2007 and propose preventive measures and control measures. Methods Using epidemiological methods and medical statistics methods for statistics, analysis and evaluation. Results During 27 years, the host density of A. xylostella was 0.31 ~ 1.80 / ha, the rate of stained flea was 28.07% ~ 66.47%, and the flea index was 0.88 ~ 3.15. The prevalence of plague was monitored in 8 years The density of hosts in the germplasm resources was 0.10 ~ 5.90 / ha, the rate of stained flea was 9.57% -57.34%, and the flea index was 0.07-1.44. The plague prevalence was detected in 9 years. Conclusion Ningxia animal plague epidemic showed periodic, intermittent occurrence. Adherence to the plague prevention, publicity and education, rodent control fleas, regional defense-based comprehensive prevention and control is the main measure to prevent and control plague.
