目的描述北京市鼠疫人间病例早期预警监测结果和本地可染疫动物种群及鼠疫耶尔森氏菌感染状况。方法在全市各级各类医疗机构开展鼠疫人间病例筛查,在门头沟区、延庆区、怀柔区、密云区和顺义区5个区设立监测点,使用夹夜法捕捉小型兽类,使用间接血凝试验测定鼠疫耶尔森氏菌F1抗体。结果 2015年全年未发现鼠疫急热待查和疑似病例,鼠间疫情监测共捕获99只啮齿类动物,鼠密度为2.83%,共包含了4种类型:大林姬鼠、北社鼠、岩松鼠和褐家鼠。77份鼠血清中未检出鼠疫F1抗体。结论北京市存在已确定的鼠疫可染疫动物社鼠和大林姬鼠,且为优势种群,但目前血清学监测结果未发现鼠疫菌感染。
Objective To describe the results of early warning surveillance of human cases of plague in Beijing and the prevalence of indigenous infective animals and Yersinia pestis in Beijing. Methods Screening of human cases of plague in all kinds of medical institutions at all levels in the city and setting up monitoring stations in five districts of Mentougou, Yanqing, Huairou, Miyun and Shunyi districts, catching small mammals with the method of catching the night and using indirect blood Condensation assay to determine Yersinia pestis F1 antibody. Results No epidemic of fever and suspected cases of plague were found in 2015. A total of 99 rodents were captured during the outbreak surveillance. The rat density was 2.83%, which contained 4 types: Apodemus agrarius, Rattus norvegicus. No plague F1 antibody was detected in 77 mouse serum. Conclusions There are confirmed plague-infected animals and Apodemus agrarius in Beijing, and they are dominant populations. However, no seroprevalence was found in the serological surveillance results.
