目的通过对三峡库区万州段鼠类及鼠传疾病的监测,分析当地鼠类活动及鼠传疾病的流行情况。方法采用鼠夹法监测鼠种及密度,对捕获的鼠进行病毒检测,通过国家疾病监测信息报告系统搜集鼠传疾病病例,并对搜集到的数据进行统计分析。结果 1997-2009年未监测到鼠疫、流行性出血热病例,仅2006年发生钩端螺旋体病2例。耕作区鼠形动物密度高于居民区,蓄水后农区室内鼠密度高于蓄水前,鼠的流行性出血热病毒检出阳性率为9.07%。结论钩体病的出现与局部区域鼠密度升高有关,应做好鼠及鼠传疾病的监测与防治工作,保护当地人群身体健康。
Objective To monitor the prevalence of murine and rodent diseases in Wanzhou section of the Three Gorges Reservoir area. Methods The mouse species and density were monitored by the mouse clamp method. The virus was detected in the captured mice. The disease cases were collected by the National Disease Surveillance Information Reporting System, and the collected data were analyzed statistically. Results No cases of plague and epidemic hemorrhagic fever were detected in 1997-2009. Only 2 cases of leptospirosis occurred in 2006. The density of mouse-shaped animals in the cultivated area was higher than that in the residential areas. The indoor rat density was higher than that of the impoundment before impoundment, and the positive rate of epidemic hemorrhagic fever virus was 9.07%. Conclusions The appearance of leptospirosis is related to the increase of rat density in the local area. Disease monitoring and prevention should be done in rats and mice to protect the health of local people.
