目的了解和掌握围场县鼠疫流行情况,分析其流行特征,为制定相应的防治策略和措施提供科学依据。方法分层随机抽取固定和流动监测乡镇3个,在抽到的乡镇中再随机抽取不同生境进行鼠密度和蚤指数调查,对所取的鼠蚤进行血清学和细菌学检验。结果固定监测野鼠平均密度1.24只/公顷,流动监测平均密度0.4只/公顷。鼠体平均蚤指数0.95,洞干蚤平均指数蚤0.088。细菌培养各种鼠308只,蚤培养19组130匹,血清学检验235份,结果均为阴性。结论提高警惕,克服麻痹思想,科学分析疫情,加强监测,采取对策,同时做好发生人间鼠疫的充分准备和应急措施,做到有备无患。
Objective To understand and grasp the prevalence of plague in Weichang County, analyze its epidemiological characteristics and provide a scientific basis for formulating corresponding prevention and control strategies and measures. Methods Stratified random sampling of fixed and mobile townships 3 were conducted. Randomly selected different habitats in the villages and towns to investigate the mouse density and flea index. Serological and bacteriological tests were carried out on the collected rat fleas. Results The average density of fixed monitoring voles was 1.24 / ha and the average flow density was 0.4 / ha. The average flea index of mice was 0.95, and the average flea population of cave fleas was 0.088. A total of 308 bacteria were cultured in bacteria, 130 in 19 fleas and serological tests of 235, the results were negative. Conclusion We should be vigilant, overcome the idea of paralysis, analyze epidemic situation scientifically, strengthen monitoring, take countermeasures, and fully prepare for and prepare emergency measures for the occurrence of plague in human beings.
