1992-1999年世界银行中国血吸虫病控制项目以其独特的策略和方法为血吸虫病控制做出了重要贡献。本文根据逐年系统收集的各项目省的项目控制和监测数据，对项目实施效果进行了评价。以1989年的调查数据为基线，计算了几项指标，并对人群感染率、牛感染率和钉螺感染率进行了相关分析。从1992年到1998年，人群总感染率、7-14岁儿童感染率和牛和水牛感染率分别下降了5.74%、59.55%和62.30%。钉螺面积增加了14.85%，钉螺感染率和感染螺密度下降了68.75%和44.95%。湖北省是项目实施期间血吸虫病防治效果最好的八个省之一。结果表明，化疗覆盖率是与人类患病率最直接相关的因素之一。化疗药物-普瑞喹酮对新发病例有效，而不是再感染。至于总体成就，为项目设定的大部分目标已经实现，特别是在人口和牛中的流行率下降。但是，我国的灭螺工作成效并不理想，需要进行整改，以寻求更适合我国国情的灭螺策略。(C)2002 Elsevier Science B.

The 1992-1999 World Bank Schistosomiasis Control Project in China contributed significantly to the disease control with its specific strategy and approach. An evaluation was made in this paper based on project control and surveillance data collected from all project provinces systematically year by year. Several indicators were computed, comparison was made using the 1989 survey data as the baseline, and correlation analysis was carried out on prevalence in humans, prevalence in cattle and buffaloes and infection rate of snails. From 1992 to 1998, the overall prevalence in human population, prevalence in children aged 7-14 and prevalence in cattle and buffaloes decreased by 5.74, 59.55 and 62.30%, respectively. Snail areas increased by 14.85% throughout the project period, while snail infection rate and density of infected snails decreased by 68.75 and 44.95%. Hubei province was among all eight provinces the most impressive in schistosomiasis control during the project. Results show that coverage of chemotherapy was among other factors the most directly-related to the prevalence in humans. The drug for chemotherapy -pritiquantel was effective for new cases rather than reinfection. As to the overall achievement, most of the objectives set for the project had,been achieved, especially the decrease in prevalence, in both human population and cattle and buffaloes. However, the achievement of snail control was not so ideal, which calls for rectification for a more applicable and practical strategy of snail control in China. (C) 2002 Elsevier Science B.V.
