ABSTRACT

Objective To understand the correlative factors of impacting schistosomiasis prevalence so as to provide the scientific evidence for drawing up the control project in Three Gorges Reservoir areas.Methods The report system of schistosomiasis was set up,and the cases were investigated.The population were screened by indirect haemagglutination test(IHA),and the serum-positive people were examined with Kato-Katz technique.The livestock and plants imported from the schistosomiasis endemic areas were investigated.Results Eighty-eight floating people returning from schistosomiasis endemic areas and 107 floating persons from endemic areas were investigated,and the serum positive rates were 1.14% and 1.87%,respectively.No schistosome eggs were found in stool examinations.There was no livestock and plant imported from schistosomiasis endemic areas.The production of local inhabitants depended on mainly cattle,and the river water contact was popular.Conclusions There are infection resources of schistosomiasis imported from endemic areas,which has a potential risk of schistosomiasis prevalence.
