摘　　要：目的掌握马来丝虫病防治后期的流行病学特征及媒介变化情况,为巩固防治成果,防止丝虫病的再度流行提供科学数据。方法采取查治残存传染源和全民普服药盐的巩固措施;开展丝虫病防治后期病原学、血清学和蚊媒监测及慢性丝虫病调查,并对收集到的资料进行分析。结果东坡区于基本消除丝虫病后的前6年,重点人群监测检出残存微丝蚴血症者7例,其中复阳3例,新检出4例;筠连、雨城区和沐川县于基本消除丝虫病后的前1~5年,横向监测各检出残存微丝蚴血症者2、1和1例,其中原阳拒治者1例,新检出3例中漏查者2例。消除丝虫病后,4个县连续监测14年未检出微丝蚴,无新发慢性丝虫病患者。结论基本消除丝虫病后的初期,丝虫病传播继续存在,采取巩固措施后未检出微丝蚴;消除丝虫病后监测表明,实施不同巩固措施后的远期效果显著。后期工作重点应放在对原慢性丝虫病患者的关怀与照料。Objective To understand the epidemiological characteristics of Brug＇s filariasis and changes in vectors in post prevention and control program period,consolidate the achievement of filariasis control program and provide scientific evidence to prevent the re-emergency of filariasis.Methods The surveillance of etiology,serology and vectors of filariasis as well as chronic filariasis survey were conducted.Mass treatment with hetrazan salt and the remaining infectious source survey were carried out too.Results During the first six years after the basic control of filariasis in Dongpo district of Meishan county,7 remaining cases with microfilaria in blood were detected among risk population in surveillance sites,3 of which were re-found cases and 4 were newly-found cases.During the first 1 to 5 years after the basic control of filariasis in Junlian county,Yucheng district and Muchuan county,2,1 and 1 remaining cases with microfilaria in blood were detected respectively by cross-sectional surveillance,of which 1 once refused treatment,2 of 3 newly found cases were missed cases.After the elimination of filariasis in 4 counties,no microfilaria in blood was detected and no new chronic filariasis cases were found for 14 years.Conclusion At early stage when filariasis was basically control,the transmission still existed.However,after the implementation of further prevention and control measures,no microfilaria was detected.The surveillance indicated that the effect of consolidating measures was obvious.Now the attention should be paid on the chronic filariasis patients.
