黔南州钩端螺旋体病疫区空间划分与宿主动物分布关系的探讨

Exploration of Space Distribution on Leptospirosis Epidemic Focus With Host Animal

目的探讨黔南州钩体病疫区与宿主动物之间的关系,为防制与预测提供依据。方法应用描述、血清、地理等流行病学方法,对流行特征及疫区形成因素进行分析。结果黑线姬鼠为主要带菌宿主,带菌率7.36%,占受检鼠类所分离菌总数的95.84%;宿主动物的地理区域性与病例聚散分布存在密切的关系。结论按照农耕方式、宿主动物区划以及病例分布建立不同类型的疫区模式。

Objective To explore the space distribution relation of leptospirosis epidemic focus with host animal in Qiannan prefecture and to provide the basic data for prediction, prevention and cure of leptospirosis. Methods The epidemiologic description, serum detection and geographic methods were applied to analyze the factors of infection focus and epidemic characteristics of leptospirosis. Results The animal Apodemus agrarius was a very important reserve host of leptospirosis with a carrier rate of 7.36%, and accounted for 95.84 % of all the check rats. The geographic distribution of host animal local area had a close relation with cases of leptospirosis aggregate distribution. Conclusion According to agriculture of leptospirosis till way that to build a mode of host animal local area with cases distribution is very important.
