安徽省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。方法在安徽省7个县选择8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8个试点村人群感染率平均下降了91.8%,有螺环境感染螺密度及钉螺感染率分别平均下降了97.2%和89.9%;每百人感染率下降1%的费用平均为841元,每千平方米有螺环境感染螺密度下降1%的费用平均为106元,每千平方米有螺环境钉螺感染率下降1%的费用平均为115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,并对其费用-效果进行了定量分析。

Objective To evaluate the effectiveness and cost-effectiveness for schistosomiasis control by synthetic measures with emphasis on infection source control.Method 8 high endemic villages in 7 counties were chosen to implement the synthetic measures of infection sources control,environmental modification,and other preventive measures implemented by public health workers for schistosomiasis control.During the intervention period,we observed changes in schistosome infection in humans,measured the rate of infection in snails,and the costeffectiveness. Results The schistosome infection rate of residents reduced by 91.8%, the density of infection snails reduced by 97.2% and the infection rate of snails reduced by 89.9% in average. The cost of infection rate reducing 1% for 100 persons was 841 Yuan, the cost of the infected snail density reducing 1% for 1 km2 area with snails was 106 Yuan,and the cost of the infection rate of snail reducing 1% for 1 km2 area with snails was 115 Yuan in average. Conclusion The synthetic measures with emphasis on infection source control were effective in schistosomiasis control, and its cost-effectiveness was analyzed.
