Objective To understand the effect of schistosomiasis control in Zhuxi Village, Xingzi County, Jiangxi Province. Methods According to the national scheme of schistosomiasis surveillance, we investigated the schistosomiasis epidemic in Zhuxi Village from 2005-2010. The epidemic data of schistosomiasis on the humans, farm cattle, and Oncomelania snails were collected, respectively and analyzed by using the method of Cochran-Armitage test. Results Human infections and snail infec-tions showed dynamic fluctuations （Z = 3.35, P = 0.000 8 ） and the density of alive snails tended to decrease gradually. The majori-ty of the infections were peasants and students. The infection rates of farm cattle were 12.31%, 3.23%, 2.94%, 3.33%, 4.44% and 2.15%, respectively from 2005-2010. Conclusion The effect of schistosomiasis control is very fine and schistosomiasis has been well controlled.
