Abstract：Objective To explore the epidemiological characteristics and spatial-temporal clusters of hand, foot and mouth disease (HFMD) in Changsha City in 2011-2014, and to provide evidence for HFMD prevention and control strategies. Methods HFMD surveillance data in 2011-2014 were collected. The SatScan software was employed with month as the time unit and township as the spatial unit to identify spatial-temporal clusters of HFMD. The MapGIS software was used to establish the database and to map case spatial-temporal clustering areas. Results A total of 100,199 HFMD cases were reported in Changsha City in 2011-2014, with the male to female ratio of 1.52:1. The cases mainly clustered in children aged 1-4 years, and scattered children acccounted for 76.03%. HFMD had double incidence peaks and occurred in all streets and townships. Pure time clustering analysis showed that the cases clustered from April to July, and pure spatial analysis indicated that the first level clusters occurred in Xingsha Street, Quantang Street, Xianglong Street and Xiaohe Township. The temporal-spatial clustering analysis revealed that HFMD clusters most likely occurred in the central and southeast areas of Changsha City from April to June, 2014. Conclusions HFMD has an obvious seasonality and high-risk areas in Changsha City in 2011－2014. The comprehensive preventive strategy should be implemented from April to July and focused on scattered children aged 1-4 years.
