【摘要】：目的评价以传染源控制为主的血吸虫病综合防治措施在云南山区的效果。方法 2006-2014年在鹤庆县金墩乡高原峡谷和高原平坝2类流行区各选择2个行政村作为观察区,实施查治病、查灭螺、健康教育、改水改厕、禁牧、建卫生畜厩、以机代牛等防治措施。以2006年螺情和病情作为基线资料,评价该综合防治措施的效果。结果高原峡谷地区人群血吸虫感染率由2006年的4.94%下降到2014年的0.06%,家畜感染率则由1.11%降至0。高原平坝地区2007年在孝廉村查出1例血吸虫病病例,其余各年均未发现病例;家畜血吸虫感染率由7.38%降至0。2014年高原峡谷和高原平坝地区钉螺面积分别较2006年下降了74.89%和75.30%;两类地区钉螺面积百分比、有螺框出现率、活螺平均密度均下降,2008年以来未再发现感染性钉螺。高原峡谷地区西甸和新庄村于2009年达到血吸虫病传播控制标准,高原平坝地区的孝廉和康福村于2014年达到血吸虫病传播阻断标准。结论以传染源控制为主的血吸虫病综合防治措施能有效控制云南高原山区血吸虫病疫情,今后应将控制传染源与消灭钉螺并重,以巩固和扩大血防成果。
[Abstract]:Objective to evaluate the effect of integrated control measures of schistosomiasis in Yunnan mountain area. Methods from 2006 to 2014, 2 administrative villages were selected as observation areas in Jinduanxian plateau canyon and Pingba plateau endemic areas in Heqing County from 2006 to 2014, to carry out investigation and treatment, to check and control snails, to improve health education, to change water into toilets, to ban animal husbandry, and to build sanitary stables. Prevention and cure measures such as replacing cattle with machine. The effect of the comprehensive control measures was evaluated by taking the snail condition and the disease condition as the baseline data in 2006. Results the schistosomiasis infection rate in plateau canyons decreased from 4.94% in 2006 to 0.06% in 2014, while the infection rate in livestock decreased from 1.11% to 0. In 2007, one case of schistosomiasis was detected in Xiaoliancun in Pingba area, and no cases were found in other years. The infection rate of schistosomiasis in domestic animals decreased from 7.38% to 0.The snail area in plateau canyon and plateau Pingba area decreased by 74.89% and 75.30% respectively compared with 2006. The percentage of snail area, the occurrence rate of snail frame and the average density of live snail decreased in the two regions, but no infected snails were found since 2008. Xidian and Xinzhuang villages in plateau canyons met the control standards of schistosomiasis transmission in 2009, and Xiaolianand Kangfu villages in Pingba area reached the standard of blocking schistosomiasis transmission in 2014. Conclusion the comprehensive control measures of schistosomiasis mainly on the source of infection can effectively control the epidemic situation of schistosomiasis in mountainous areas of Yunnan Plateau. In order to consolidate and expand the results of blood control, we should pay equal attention to the control of source of infection and the elimination of Oncomelania hupensis in the future.
