Abstract: Objective Objective To investigate the schistosomiasis epidemic situation changes after its transmission interrupted in Lufeng County in 1986,so as to provide the evidence for formulating the interventions for schistosomiasis elimination. Meth Meth? ? ods ods The surveillance of Oncomelania hupensis snail was performed by the systematic sampling,environmental sampling and special environmental comprehensive survey methods. The surveillance of human population was carried out by the serological screening method,and the positives were re ? examined with the stool hatching method. The surveillance of livestock was per? formed by the plastic cup of pipe jacking hatching method. Results Results The living snails were detected in Lufeng County from 1987 to 2007 except in 1988 and 1994. The two import buffalo infected with schistosomes were detected in 2001 and no local infected livestock were found. Since 2004,the comprehensive measures,including the social control strategy and survival snail elimina? tion,were carried out,and no snails were detected and no schistosome infected persons or livestock were found for 7 consecu? tive years since 2008. Conclusions Conclusions The achievement of schistosomiasis transmission interrupted has been consolidated in Lufeng County,but most of the historical snail environments have not been modified and there are still snail breeding conditions. Therefore,we should continue to carry out the snail surveillance.

摘要: 目的 目的 分析云南省禄丰县1986年达到血吸虫病传播阻断后疫情变化, 为消除血吸虫病提供参考依据。 方法 方法 1987-2014年采用系统抽样结合环境抽查法调查禄丰县螺情, 特殊环境采用全面细查法调查; 人群病情监测采用血清学 方法筛查, 阳性者再用尼龙绢集卵孵化法确诊; 家畜病情监测采用塑料杯顶管孵化法。 结果 结果 1987-2007年21年中, 除 1988年和1994年由于调查范围较小没有查出钉螺外, 其余各年均查到活螺; 2001年检出输入性血吸虫感染病牛2头, 未 检出本地病畜。自2004年起采取以社会措施为主导、 消灭残存钉螺为重点的综合治理措施, 自2008年以来已连续7年 查不到钉螺, 亦未检出血吸虫感染病人和病畜。 结论 结论 禄丰县血吸虫病传播阻断成果巩固; 但很多历史有螺环境尚未 得到改造, 仍具备钉螺孳生条件, 须继续开展螺情监测。
