Abstract: Objective　The present study was conducted to research the dynamic endemic situation in Jiangsu, so as to provide evidence and basis for policy-making and evaluation of schistosomiasis control in Jiangsu province. Methods　According to the National Scheme of Schistosomiasis Surveillance, the endemic situation of schistosomiasis was monitored in 8 national schistosomiasis surveillance sites in Jiangsu. Results　Schistosomiasis patients were found positive in fecal examination in 2 surveillance sites, and the infection rate of permanent residents were 0.10%. Oncomelania snails were found at 5 surveillance sites, and in 4 of the 5 sites infectious oncomelania snails were found. The overall density of infectious oncomelania snails was 0.002 24/0.1m2. At 1 site, sheep were found to be positive in fecal examination; positive cattle were not found; and the overall infection rate was 0.90% of the livestock. Conclusion　Compared with the situations in 2005 and 2006, the endemic prevalence in the surveillance sites decreased in 2007. However, in some places the area and density of local infectious oncomelania snails were still high, and the the schistosomiasis infection rates of fishermen increased. Therefore, stronger control is necessary in the future to further reduce the prevalence of schistosomiasis.
