目的掌握呼和浩特市2004-2014年鼠疫疫源地宿主动物和媒介种类、数量及分布,分析鼠疫流行规律,为鼠疫防控提供科学依据。方法按照《内蒙古自治区鼠疫监测工作方案》进行。结果长爪沙鼠密度在1.30~2.78只/hm2范围内;鼠体染蚤率2004年、2005年和2014年均超过20.00%,其余年份在6.54%~17.70%之间。媒介蚤指数2005年最高,为0.75;2007年最低,为0.09。2010年检出阳性鼠(自毙长爪沙鼠)2只,分离鼠疫菌2株。结论呼和浩特市鼠疫疫源地又重新进入活跃状态,必须进行长期有序监测,及时发现疫情,及时控制处理。
Objective To understand the species, quantity and distribution of host animals and vectors in the plague foci of Hohhot from 2004 to 2014, analyze the epidemic rules of plague and provide a scientific basis for the prevention and control of plague. Methods According to “Inner Mongolia Autonomous Region plague monitoring program”. Results The density of Mongolian gerbils was between 1.30 and 2.78 / hm2. The rate of flea flea infection was over 20.00% in 2004, 2005 and 2014, and between 6.54% and 17.70% in other years. Media flea index highest in 2005, was 0.75; in 2007 the lowest, was 0. 09. In 2010 detected positive mice (self-killed Gerbils) 2, isolated two strains of Yersinia pestis. Conclusion The plague origin in Hohhot re-entered the active state, which must be monitored in a long-term and orderly manner. Epidemics should be found in time and controlled in a timely manner.
