摘要
目的研究云南高原山区以传染源控制为主的血吸虫病综合防治策略的成本-效果和成本-效益,为血吸虫病防治策略的制定或调整提供科学依据。方法在高原平坝型(坝区)和高原峡谷型(山区)血吸虫病疫区各选择2个村,分别作为实验组和对照组。实验组实施改水、改厕、禁牧等综合治理措施,对照组实施常规防治措施。分析2005～2007年间2类疫区以及实验组与对照组的防治效果、成本-效果和成本-效益。结果实验组2个村3年后人群感染率分别下降93.36%和96.44%;对照组2个村分别下降83.24%和84.38%,实验组优于对照组;坝区实验组与对照组成本-效果差别不大,山区实验组优于对照组。坝区成本-效益显著高于山区,实验组和对照组效益/成本比值(BCR)相差不大。结论与常规防治策略相比,以传染源控制为主的综合防治策略具有较好血防效果和效益,在人群感染率较高时,适用于高原山区。
Objective To study the cost-effectiveness and cost-benefit of the integrated schistosomiasis control strategy with emphasis on infectious source control in mountainous areas of Yunnan Province, so as to provide the evidence for the establishment or adjustment of the schistosomiasis control strategy. Methods Xinlian Village in dam areas and Qieye Village in mountainous areas were selected as an experimental group where the integrated strategy with an emphasis on infection source control was implemented. Yonglian Village in dam areas and Qiandian Village in mountainous areas were selected as a control group where conventional control measures were undertaken. The control effect was observed and compared between the two groups from 2005 to 2007, and both the cost-effectiveness and cost-benefit were studied. Results The infection rates of two villages in the experimental group decreased by 93.36% and 96.44% , respectively, and the decreased percentages of the two villages in the control group were 83.24% and 84.38%, respectively. The difference was statistically significant between the experimental group and control group. The cost-effectiveness in the experimental group was significantly lower than that in the control group in the mountainous areas. While in the dam areas, the difference was not significant. The cost-benefit in the dam areas was significantly higher than that in the mountainous areas. The differences of cost-effectiveness ratio and benefit-cost ratio （BCR） between the experimental and control groups were not significant. Conclusions The integrated control strategy focusing on infectious source control has better control effects and benefits comparing to the conventional control strategy when the infection rate of residents is high, and the integrated control strategy is fit to apply in endemic regions of mountainous areas.
