目的：分析云南省高原山区血吸虫病疫区达到传播阻断（传阻）前后螺情与病情变化规律。方法采用回顾性调查方法，收集、记录剑川县达到传播控制（传控）前10年至2008年的疫情资料，建立调查资料数据库，分析各流行村螺情、病情变化趋势和规律。结果剑川县从1954年开始开展防治血吸虫病，1976年达血吸虫病疫情控制标准，人群感染率为0.65%，钉螺感染率为0.40%；1981年达传控标准，人群感染率为0.34%，钉螺感染率为1.41%；1993年达传阻标准，人群感染率、钉螺感染率均为0；3个重要防治阶段，在整个防治过程中螺情、病情指标时有波动、上升，但仍延着逐渐下降的趋势，并在一个较低的感染率水平上持续较长的时间，才达到传阻阶段。结论云南省高原山区血吸虫病从疫情控制到传控相对耗时较短，从传控到传阻需时较长。原血吸虫病流行区通过防治有可能存在“有螺无病”区域。

Objective To understand the dynamic status of schistosomiasis epidemic situation and Oncomelania hupensis snail status before and after the schistosomiasis transmission interrupted in the mountainous areas of Yunnan Province. Methods The data of schistosomiasis epidemic situation and snail status were collected and analyzed statistically in Jianchuan County from 10 years before the schistosomiasis transmission interrupted to 2008. Results The schistosomiasis control began in Jianch-uan County from 1954. In 1976,the criteria of schistosomiasis endemic controlled were reached,and the infection rate of popu-lation was 0.65%and the infection rate of snails was 0.40%. In 1981,the criteria of schistosomiasis transmission controlled were reached,and the infection rate of population was 0.34%and the infection rate of snails was 1.41%. In 1993,the criteria of schis-tosomiasis transmission interrupted were reached,and the infection rate of population was 0 and the infection rate of snails was 0. There was a fluctuation in the schistosomiasis epidemic situation and snail status during the whole control duration ,but the trend was decreasing. Conclusion The time from schistosomiasis endemic controlled to transmission controlled is relatively short,but the time from transmission controlled to transmission interrupted is relatively long. In the original schistosomiasis en-demic areas,there might be some areas where there is no the disease bud there still are snails.
