Objective To evaluate the final effect of long-term planning of prevention and control of schistosomiasis in Fanchang County. Methods Blood samples were collected from Fanchang County in 2004-2014. The epidemic situation of schistosomiasis was analyzed to evaluate the control effect. Results A total of 1 938 schistosomiasis patients were treated in the county from 2004 to 2014, and 64 256 people were treated to expand the chemotherapy. Twelve first-time patients were treated and 2,745 first-time patients were treated for chemotherapy. A total of 7 758.1 hm 2 of drugs were used to cure schistosomiasis, 36.0 hm ~ 2; all key villages have implemented source control measures. The prevalence of schistosomiasis in the population decreased to 0.27% by 2014; the incidence of acute schistosomiasis infection and cattle infection rate dropped to 0; the area of Oncomelania snails reduced to 103.20 hm ~ 2; and the oncomelania and infectious Oncomelania showed an overall downward trend. Conclusion The implementation of a comprehensive blood-protection strategy dominated by human and animal screening chemotherapy, snail control, health education and infection source control has achieved remarkable results. The county has reached the standard of transmission control of schistosomiasis.
