血吸虫病防控技术集成研究与示范 Ⅱ疫情纵向防治效果评价

Research and demonstration of comprehensive measures of schistosomiasis prevention and control technology Ⅱ Longitudinal evaluation on control effect

目的评价血吸虫病防控技术集成研究与示范对控制血吸虫病疫情的防治效果。方法通过在示范区实施封洲轮牧、改水改厕、健康教育等控制血吸虫病流行的综合措施,并开展血吸虫病疫情调查及相关问卷调查,评价其防治效果。结果通过连续3年的血吸虫病防控技术实施,示范区居民血吸虫感染率由3.57%降至0.83%,耕牛血吸虫感染率由17.14%降至0,洲滩未发现阳性钉螺。结论封洲轮牧、改水改厕、健康教育等综合防治技术是控制鄱阳湖区血吸虫病流行的有效措施。

Objective To evaluate the effect of comprehensive measures of schistosomiasis prevention and control technique. Methods The comprehensive measures including forbidding grazing on marshlands, renovating latrines and supplying safe water, and health education were carried out in a demonstrative area, and the schistosomiasis endemic situation and other relative factors were investigated. Results After the control measures were carried out for 3 years, the prevalence of schistosomiasis in human decreased from 3.57% to 0.83%, and the infection rates of cattle decreased from 17.14% to 0. No infected Oncomelania snails were found on the marshlands in the demonstration area. Conclusion The comprehensive measures aforementioned are effective in the control of schistosomiasis in Poyang Lake region.
