中蒙口岸鼠疫疫情监测与突发疫情处理

目的通过对中蒙口岸多年鼠疫疫情监测数据分析,掌握疫源地鼠疫动物病流行规律,以便进一步监控疫情和应对鼠疫突发卫生事件。方法按照动物鼠疫监测标准、鼠疫自然疫源地及动物鼠疫流行判定标准开展监测。结果在早已证实的长爪沙鼠疫源地(二连口岸地区),1984～2003年有8个年份判定疫鼠27只,疫蚤32组74匹,该地区鼠间鼠疫每隔3～4年有一次流行,每次流行都可在鼠、蚤体内检到鼠疫菌。连续3年从蒙古国进口的旱獭皮采样监测1431份,检出鼠疫F1抗原阳性15份,最高滴度达1:10240。2003年对该口岸地区发生的鼠疫动物病流行进行了疫情处理。结论在一些处于鼠疫疫源地的口岸系统的、长期的开展鼠疫监测意义深远。

Monitoring and disposal of plague epidemic situation at China-Mongolia frontier

Objective Analyze the data of monitoring at China-Mongolia frontier through lots of years, find out the rules of animal plague in the epidemic region ,control the epidemic situation and deal with the break out events effectively. Methods Monitor the plague epidemic situation according to the standard of animal plague and other related standards. Results In the confirmed epidemic focuses of Mongolian gerbil (the Er-Lian Port), plague bacteria infected 27 gerbils, 74 fleas were identified as 32 groups in 8 years from 1984 to 2003. Epidemic plague in rat-sphere broke out one time every 3 years, at the same time ,Yersinia pestis could be found out in gerbils and fleas. By monitoring of the 1,431 marmot skin samples imported from Mongolia in 3 consecutive years, F1 plague antigen of 15 samples identified positive, and the highest titer was 1:10,240. We finished some effective sanitation disposal on animal plague in the port area 2003. Conclusion The systemic and long-term monitoring of epidemic situation at plague-outbursting ports is very meaningful.
