Objective To understand the endemic situation and control effect of schistosomiasis in the Fu River system in Yangxin County in recent 10 years. Methods The data of endemic situation and control of schistosomiasis in this area from 2003 to 2012 were collected, and the variation trends of morbidity and snail situation were analyzed longitudinally. Results Compared to 2003, the infection rates of human and cattle decreased by 97.50% and 99.44%, respectively. The total number of patients with acute schistosomiasis and advanced schistosomiasis decreased by 100% and 21.09%, respectively, and the number of schistosome infection of cattle decreased by 99.85%. Meanwhile, the Oncomelania snail area and the infection rate of snails decreased by 26.97% and 100%, respectively. Conclusion Though the endemic situation of schistosomiasis in the Fu River system in Yangxin County decreased obviously year by year, the comprehensive control measures and management of floating population in this arrea should still be strengthened to prevent the endemic situation from rebounding.
