Abstract:

Objective  To assess the schistosomiasis endemic status in the surveillance sites in Hanchuan City for scientific evidence for prevention and control of local schistosomiasis. Methods  Surveillance over the schistosomiasis endemic was performed from 2009 through 2014 in separate sites in Hanchuan city in compliance with the Surveillance Protocol Across Hubei Province. Results  The infection rate of Schistosoma japonicum was declined by 73.30%(from 1.76% in 2009 to 0.47% in 2014), and no single cattle infection occurred in 6 years of period. The density and rate of infected snails were both decreased by 100%. Conclusion  The data from the surveillance sites show that the schistosomiasis endemic is effectively controlled in Huachuan city. In order to lay a foundation for complete interruption of the transmission of schistosomiasis in this area, enhanced surveillance is necessary in our following targets.
