Abstract Objective To learn the temporal-spatial distribution and clustering of hand-foot-mouth disease (HFMD) in Xiaoshan in 2014,and to provide reference and basis for prevention and control.Methods The HFMD data of Xiaoshan in 2014 was derived from the China Information System for Diseases Control and Prevention. The vector map was created by Map Info 10.0 on the background of 1∶65 000 zoning map ,extracted village and community geographical position information from Baidu map. At the village level,the spatial autocorrelation analysis and spatial scanning analysis were made using software ArcGIS10.2 and SaTScan9.2. Results In Xiaoshan, the epidemic curve of HFMD in 2014 showed two peaks, during April to July and during September to October. The global spatial autocorrelation Moran's I index was 0.442 7(P<0.001),and the global Getis-Ord G value was 0.003 3,(E(G)=0.002 1,Z(G)=11.82, P<0.001). Local autocorrelation analysis showed that the cluster state was high- high. Ningwei Street had the most hot spots. Five statistically significant HFMD clusters were identified by space-time scan statistics, the most likely cluster was located in Heshang Town,from January 6 to February 4 (RR=23.00, LLR= 17.45,P<0.05). Conclusion In Xiaoshan, the major epidemic peak of HFMD in 2014 was from April to July. A positive spatial correlations was found, and the disease showed a distinct regional distribution feature and temporal-spatial clustering. The clusters were observed including the villages and communities of rural-urban continuum and in vicinity of industrial development zone in countryside.
