Objective: To understand the schistosomiasis epidemic situation after the attainment of criteria for infection control, and evaluate the effect of control measures in Jinxian County, Jiangxi Province.
Methods: The data of schistosomiasis epidemic situation including the infection rates of residents and Oncomelania snails were collected and analyzed statistically in the infection-controlled, transmission-controlled, and transmission-interrupted areas in Jingxian County from 2008 to 2011.
Results: The antibody positive rates of population were decreasing year by year from 2008 to 2011 with the rate in the infection-controlled area being higher than the rates in the transmission-controlled and the transmission-interrupted areas. In the infection-controlled area, the stool examination positive cases decreased from 29 cases in 2008 to 1 in 2011. In 2008, the spots with infected snails in the infection-controlled area and the transmission-controlled area were 63 and 5 spots, respectively. The spots with infected snails in the infection-controlled and transmission-controlled areas in 2011 decreased by 95.23% and 80.00%, respectively compared with that in 2008.
