【摘要】 目的了解耕牛在四川省血吸虫病传播和防治中的作用。方法普查全省流行村耕牛存栏情况 ,按 2 0 %流行村比例抽样调查耕牛感染情况。结果耕牛是四川省血吸虫病传播的主要污染源 ,IPC为 87.70 % ;耕牛养殖量与人群感染呈正比 ,养殖越多 ,感染越重 ;养牛户人群感染率明显高于无牛户 ,有病牛的家庭人群感染率是其它家庭的 4～ 70倍。结论加强耕牛血吸虫病防治是当前山丘型血吸虫病流行区的主要任务。更多还原

【Abstract】 Objective To study the roll of farm cattle played in trnasmission and control of schistosomiasis in Sichuan. Method The farm cattle in shed in endemic villages of Sichuan were generally surveyed, and a sampling survey on infected cattle in 20% endemic villages was carried out. Results The farm cattle constituted the main transmission resource of human schistosomiasis infection in Sichuan and IPC (index of potential contamination) reached 87.70%. The amount of cattle and human infection rate revealed direct ratio, i.e. the more the number of cattle was, the higher the infection rate of villagers would be. The human infection rate in households with cattle was significantly higher than that in households without cattle. The human infection rate in households with infected cattle was 4~70 folds higher than that of other households. Conclusion The main task of schistosomiasis control in mountainous region is to strengthen the shistosomiasis control in cattle.更多还原
