Effect of wild feces detection in Oncomelania hupensis environments on sur-veillance of infection source of schistosomiasis / 中国血吸虫病防治杂志

ABSTRACT

Objective To evaluate the effect of wild feces detection in Oncomelania hupensis environments on the surveil?lance of infection source of schistosomiasis,and find the weakness in schistosomiasis control in Hubei Province,so as to put for?ward the targeted strategies and measures. Methods Four environments with O. hupensis snails in endemic areas of Hubei Provinces,where human and livestock often haunted,were selected according to the river systems,namely the Juzhanghe River beach in Jingzhou City,Changjiang River beach in Jiayu County,Hanbei River beach in Tianmen City,and Changshou River beach in Zhongxiang City,then the snail survey and wild feces detection were implemented in the selected environments. Re?sults There were O. hupensis snails,livestock,wild feces of cattle or sheep as well as positive cattle feces found in all the 4 environments,and the positive rate of schistosome miracidium incubation was 47.62%. Conclusion The schistosome miracidi?um positive rate of wild feces of cattle is high in the environments with snails in endemic areas of Hubei Province ,which has high risk for schistosomiasis transmission.
