OBJECTIVE
To evaluate the effect of a water-saving irrigation project on schistosomiasis control.
METHODS
The Oncomelania snail situation before and after the water-saving irrigation project was investigated, and the data of snails and schistosomiasis of people in the area of the water-saving irrigation engineering were collected and analyzed statistically.
RESULTS
The incidence of frames with snails declined from 10.70% to 2.27% after actualized water-saving irrigation project, and the snail density declined from 0.42 snails/0.1 m(2) to 0.10 snails/0.1 m(2). The snails were eliminated in 57% of the ditches. The snail area and schistosome infection rate of residents declined obviously.
CONCLUSION
The water-saving irrigation project is effective in schistosomiasis control and has good social and economic benefits.
目的
评估节水灌溉项目对血吸虫病防治的效果。
方法
调查节水灌溉项目实施前后的钉螺情况，收集节水灌溉工程区域内的钉螺及人群血吸虫病数据并进行统计学分析。
结果
实施节水灌溉项目后，有螺框出现率从10.70%降至2.27%，钉螺密度从0.42只/0.1平方米降至0.10只/0.1平方米。57%的沟渠内钉螺被消灭。居民的钉螺面积和血吸虫感染率明显下降。
结论
节水灌溉项目在血吸虫病防治方面有效，具有良好的社会和经济效益。
