摘要: 目的运用流行病学方法制订科学灭鼠对策,控制奉贤县肾综合征出血热(HFRS)的流行。方法依据1986~1995年奉贤县HFRS流行特征及黑线姬鼠、褐家鼠等5种宿主动物均携带汉坦病毒(HV)的监测结果,于1996~2001年的每年春秋两季,选取溴敌隆配制毒饵,对1986~1995年的历史疫点及以后逐年出现的新疫点,在室内、外环境及村(集镇)周田野同步投毒饵灭鼠;非疫点仍按1995年以前的方法以室内灭鼠为主,兼顾室外环境。同时,在全县25个乡镇(农场)每月于各村轮转用夹夜法以300夹日监测鼠密度,然后计算年平均鼠密度。结果全县年平均鼠密度和HFRS年平均发病率,1996~2001年比1986~1995年分别下降68.55%和64.36%。结论长达6年的动态观察结果证明,运用流行病学方法制订的科学灭鼠控制对策,可有效地控制长期居高不下的HFRS流行。

Abstract: Objective To evalute the effective intervention for controlling rodents based on epidemiological methods and the epidemic of Hemorrhagic Fever with Renal Syndrome(HFRS) in Fengxian district.Methods On the basis of the epidemic features of HFRS in Fengxian district in 1986- 1995 and the surveillance results that the HFRS virus reservoirs were found all the five species of rodents including Apodemus agrarius and Rattus norvegicus,the bait with bromadiolone were chose and conducted for the elimination of both wild and domestic rodent.The poison baits should be laid in and around the house as well as in field around the villages and towns at the same time.This rodent control programme was conducted only on old epidemic foci emerged over the period 1980- 1995 and the new foci from then on maintained during the spring and autumn every year in 1996- 2001.Using the measures adopted before 1995,the rodent control was carried out in and around the house but mainly inside the house on non-foci.The densities of rodents were in surveillance in 25 towns including farms all over the district and 300 rat-traps were setted in turn on different places of each village every night.The annual mean densities of rodents were then calculated out.Results The annual mean density of rodents and the annual mean incidence of HFRS in the whole district over the period 1996- 2001 in comparison with 1986- 1995 decreased dramatically for 68.55% and 64.36% respectively.Conclusion It was demonstrated by dynamic observation over six years that the epidemic of HFRS could be effectively controlled by the strategy of rodent control based on epidemiological methods.
