Observation on comprehensive control strategy for schistosomiasis with emphasis on infectious source control in Poyang Lake areas from 2009 to 2014

To evaluate the long-term effect of the comprehensive control strategy for schistosomiasis with emphasis on infectious source control in marshland-type endemic areas of Poyang Lake.Three heavy endemic villages with schistosomiasis in the lake areas were selected as pilots for the comprehensive control strategy which included replacing bovine with tractors and forbidding grazing on marshlands. The data of schistosome infections of residents and Oncomelania hupensis snails were collected and analyzed statistically from 2009 to 2014.There were no patients with schistosomiasis through feces examinations in the 3 pilot villages. The average density of live snails in Niuzhou marshland showed a decline trend and the density was stable in Liulingwei marshland. There were no infected snails in the 2 marshlands, and no schistosome adult worms were found in the sentinel rats.The implantation of the comprehensive control strategy for schistosomiasis with emphasis on infectious source control can control the prevalence of schistosomiasis during a long period.
