Abstract: Objective Objective To analyze the spatial?time distribution characteristics of schistosomiasis in Jiangling County，Hubei Province from 2006 to 2011. Methods Methods The surveillance data of schistosomiasis of Jiangling County from 2006 to 2011 were col? lected，and a spatial database was established. The spatial?time permutation cluster analysis was performed by SaTScan 9.1.1 to detect the spatial?time cluster areas of schistosomiasis，and a risk map was drawn by ArcGIS 10.0. Results Results Compared to 2006， the infection rates of human，cattle and Oncomelania hupensis snails decreased by 47.67%，93.34% and 52.41%，respectively in 2011. The space? time permutation clustering analysis of the infection rates of human，cattle and snails showed 4，3 and 4 clusters，respectively，and all the clustered areas were distributed in inner embankment areas. Conclusions Conclusions From 2006 to 2011，the schistosomiasis endemic situation presents a decline trend in Jiangling County. The detected cluster areas are the im? portant areas for schistosomiasis control. The space?time permutation statistics could be used in the analysis of endemic situation of schistosomiasis.
