Effect of integrated control of schistosomiasis in Shashi District from 2009 to 2013

OBJECTIVE: To evaluate the effect of integrated schistosomiasis control in Shashi District from 2009 to 2013, so as to provide the evidence for the development and adjustment of schistosomiasis control strategies. METHODS: The data of integrated schistosomiasis control from 2009 to 2013 were collected and analyzed for the epidemic situations of human, livestock and Oncomelania hupensis snails. RESULTS: From 2009 to 2013, the infection rates of human and cattle decreased from 2.24% and 1.92% to 0.63% and 0, with decrease rates of 71.88% and 100%, respectively; the area with snails decreased from 760.40 hm2 to 715.08 hm2, with a decrease rate of 5.69%; the occurrence rate of frames with living snails and the average density of living snails decreased from 26.32% and 0.67 snail/0.1 m2 to 18.30% and 0.53 snail/0.1 mi2, with decrease rates of 30.47% and 20.90%, respectively. No infected living snails were found from 2012 to 2013. CONCLUSION: The integrated schistosomiasis prevention and control strategies with emphasis on infectious source control could effectively reduce the infection rates of human and cattle as well as the snail situation.
