【摘要】 目的探索以机代牛、改水改厕综合治理控制血吸虫病传播的效果。方法选择湖沼型血吸虫病流行村2个,1个为试点村,实施以机代牛、改水改厕措施,一个对照村,实施一般防治措施,分别观察其控制人群血吸虫和肠道寄生虫感染、野粪污染、钉螺感染的效果。结果对策实施2年后,试点村居民血吸虫感染率下降了46.3％,对照村人群感染率上升了19.7％,并且时有急性感染发生。试验村居民肠道寄生虫感染率下降了85.6％,对照村上升了152.2％,对照村滩地阳性螺密度上升的幅度是试点村的3.98倍。结论以机代牛、改水改厕综合措施,不仅能够有效地控制血吸虫病的流行,而且能够改善农村落后的卫生状况,降低肠道寄生虫病,提高人群整体健康水平,是新形势下控制血吸虫病的一条有效途径。更多还原

【Abstract】 Objective To learn the effect of the comprehensive measures of replacing cattle with machine and reconstructing water supply and lavatory to control the transmission of schistosomiasis.Methods To select two villages in the marshland endemic region,one was pilot village which carried out the measures replacing cattle with machine and reconstructing water supply and lavatory,one was control village which carried out the general measures.To ob- serve the control effect on the infection of schistosome and other helminthes,the contamination of wild feces and the infection of snail mere surveyed.Results After two years,the infection rate of schistoscrne of the people decreased by 46.3% in the pilot village and increased by 19.7% in the control village.The infection rate of helminthes decreased by 85.6% in the pilot village and increased by 152.2% in the control village.The scope of density of positive snail increased in the control village was 3.98 times higher than that of the pilot village.Conclusion The comprehensive measures of replacing cattle with machine and reconstructing water supply and lavatory not only can control the trans- mission of schistosomiasis,but also can improve the poor sanitation in the countryside,reduce verminosis,improve the health of the whole people.It was one of effective ways to control schistosomiasis in the present position.更多还原
