Background and aim To investigated the epidemiological and etiological characteristic of Hand-Foot-Mouth disease in Chongqing, China from 2010 to 2013. Methods Descriptive epidemiological methods were used to describe the epidemic characteristics of 3760 hospitalised cases with HFMD in Chongqing children’s hospital during 2010 to 2013. The pathogens from 830 stool samples were determined by nested RT-PCR and the molecular characteristics were analysed by the phylogenetic trees. Results There were two epidemic peaks every year during 2010 to 2013 in Chongqing. One occurred from April to July and another occurred from October to December. Most (91.22%) of the patients were under 5 years old and 76.28% were Conclusions HFMD had two epidemic peaks each year in Chongqing from 2010 to 2013.
