摘　　要：目的评价基于垸尺度的实施以控制血吸虫病传染源为主综合措施的效果。方法以"垸"为单位收集安乡县血吸虫病病情、螺情等数据,采用趋势χ2检验对数据进行统计分析。结果安保垸累计淘汰牛2 606头,干预后第5年,人群感染率由干预前的8.04%降至0.70%,垸外钉螺感染率由0.56%降至0.05%;安澧垸累计淘汰牛535头,干预后第3年,人群感染率由干预前的5.87%降至1.09%,垸外钉螺感染率由0.17%降至0.07%;安造垸累计淘汰牛62头,干预后第2年,人群感染率由干预前的2.67%降至0.39%,垸外钉螺感染率由1.12%降至0;安昌垸未淘汰牛,人群感染率由干预前的1.76%降至1.23%。结论以淘汰牛为主的血吸虫病传染源控制综合措施能较大幅度降低疫区人群和钉螺感染率。Objective To evaluate the effects of comprehensive measures with emphasis on schistosomiasis infectious source control at the embankment level. Methods The comprehensive measures with emphasis on schistosomiasis infectious source con- trol were carried out, and the data of human and Oncomelania snail infection rates were collected and analyzed statistically at em- bankment levels. Results In Anbao Embankment, except the other comprehensive measures were performed, 2606 buffaloes were removed. The infection rates of residents reduced from 8.04% before the intervention to 0.7% after the intervention, and the infection rates of snails reduced from 0.56% to 0.05%. In Anli Embankment, 535 buffaloes were removed. In the third year after the intervention, the infection rates of residents reduced from 5.87% to 1.09%, and the infection rates of snails reduced from 0.17% to 0.07%. In Anzao Embankment, 62 buffaloes were removed. In the second year after the intervention, the infection rates of residents reduced from 2.67% to 0.39%, and the infection rates of snails reduced from 1.12% to 0.00%. In Anehang Embank- ment, the buffaloes were not removed. The human infection rates reduced from 1.76% before the intervention to 1.23% after the in- tervention. Conclusion The comprehensive measures with emphasis on schistosomiasis infectious source control, especially the buffalo＇ s removal, are effective in the control of schistosome infection rates of residents and snails.
