The surveillance of schistosomiasis in Shicheng Village, a national schistosomiasis surveillance site in Yangzhong City from 2005 to 2010 showed that snail areas were 16.43 hm2, the occurrence rates of frames with living snails and mean densities of living snails exhibited a declining trend year by year, and the infected snails were only found in 2007. The sero-positive rates in residents were 1.81%, 0.98%, 0.29%, 0.28%, 0.47% and 0.51%, respectively from 2005 to 2010. However, no stool-examination -positive persons were detected. During the period, no acute infections occurred, and no advanced cases and infected animals were detected. It is indicated that schistosomiasis has been effectively controlled in the surveillance site. However, snails remain present, so comprehensive control and surveillance of infectious sources should be further strengthened.
