以传染源控制为主的血吸虫病综合防治策略实施效果与费用——效果分析

Analysis on effectiveness and cost-effectiveness for schistosomiasis control by synthetic measures with emphasis on infection source control

目的评价以传染源控制为主的综合防治措施预防血吸虫病的效果及其费用-效果。方法在当涂县选择1个较严重的血吸虫病流行村实施传染源控制、综合治理和卫生血防项目等综合防治措施,通过2年措施的实施观察其预防血吸虫病效果及费用-效果情况。结果试点村人群感染率平均下降了100.0%,有螺环境钉螺密度下降了94.5%,并保持无感染性钉螺状态;每百人感染率下降1%的费用平均为441元,每千平方米有螺环境活螺密度下降1%的费用平均为23元。结论实施以传染源控制为主的综合防治策略具有很好的预防血吸虫病效果。

Objective To evaluate the effectiveness and cost-effectiveness for schistosomiasis control by synthetic measures with emphasis on infection source control. Methods 1 higher endemic village was chosen to implement the synthetic measures of infection sources control , environmental modification , and other preventive measures for schistosomiasis control. The effectiveness on schistosomiasis control and the cost-effectiveness were observed after the intervention measures carried out for two years. Results The infection rate of residents reduced by 100.0%, the density of living snails reduced by 94.5% , and infective snails were not found. The cost of infection rate reducing 1% for 100 persons was 441 Yuan, and the cost of hying snail density reducing 1% for 1 km^2 area with snails was 23 Yuan. Conclusion The synthetic measures with emphasis on infection source control were effective for schistosomiasis control.
