Abstrakt:	Objective: To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in Hanchuan City (marshland and lake endemic regions). Methods: The data of comprehensive schistosomiasis control in Hanchuan City from 2004 to 2013 were collected, and the change trends of the Oncomelania hupensis snail status and the infection situation of human and livestock were analyzed to evaluate the control effect. Results: After the implementation of the comprehensive measures, the infection rates of residents and cattle decreased from 6.38% and 8.11% in 2004 to 0.16% and 0 in 2013 respectively. There were no acute schistosomiasis patients since 2007, no new infection cases since 2011, and no infected snails since 2012. Compared with 2004, the occurrence rate of frames with living snails and the average density of living snails decreased by 56.78% and 68.35%, respectively, but the snail area and susceptible area increased by 0.62% and 7.10%, respectively. In 2013, all the 367 endemic villages in 26 townships reached the criteria of transmission controlled. Conclusions: The comprehensive schistosomiasis control measures based on infection source control can control the schistosomiasis transmission effectively in marshland and lake endemic regions. When consolidating the achievement, the snail area in inner embankment should be compressed to prevent the schistosome re-infection in human and livestock.
