承德避暑山庄肾综合征出血热监测结果分析

The Analysis on the Renal Syndrome(HFRS) in the Mountain Resort of Chengde

目的通过连续调查承德市避暑山庄肾综合征出血热(HFRS)宿主动物来源、种群、带毒情况,探讨疫源地变化的原因,为旅游地区防制HFRS提供依据。方法采用夹夜法开展鼠密度调查,采集鼠肺监测HFRS感染状况,用EXCEL统计分析数据。结果从2002年开始避暑山庄HFRS监测,山庄内鼠带毒率居较高水平,以后逐年下降,2003年下半年该动物园迁出,该地带毒鼠生存环境明显改变,鼠密度和鼠带毒率降低,但是避暑山庄内形成了带毒鼠长期存在的环境,成为承德市自然疫源地之一。结论外来生物带来的生物安全隐患是HFRS自然疫源地的形成的重要因素之一,在今后旅游地区的HFRS防制工作中应进一步得到重视并加以防范。

Objective To explore the masons for the changes in epidemic focus and provide the theoretical basis for the control of HFRS in the tourist areas through investigating sources, population, carders of host animal with hemorrhagic fever with renal syndrome （HFRS） in the Mountain Resort of Chengde. Methods To survey the rat density by collecting rat lung and monitoring HFRS infection status, to analyze the statistical data with EXCEL Results from 2002 we carried out the HFRS monitoring in the Mountain Resort, we discovered that rat with HFRS virus are very higher, then it declined year after year. In the second half of 2003, the zoo was moved out of the resort, and the living environment for the mouse with virus changed obviously there, and rat density and rate of mice infected with virus became lower, but the environment with rats with virus in the Mountain Resort existed for a long time which became one of the natural focl. Conclusion The security risks derived from external organism is one of the important factors of the formation of natural foci of HFRS, therefore further attention and guard against them should he emphesised in the future HFBS work.
