Abstract：Objective To analyze the epidemiological features of hand, foot and mouth disease (HFMD) in Chenzhou City from 2012 to 2014 so as to provide scientific evidence for HFMD prevention and control. Methods Descriptive epidemiological methods were used to analyze the monitoring data about HFMD in Chenzhou City from 2012 to 2014. Results A total of 33,587 cases of HFMD were reported in Chenzhou City from 2012 to 2014, and the annual average incidence rate was 214.89/100,000. There were statistically significant differences in the reported incidence rates among the three years (χ2=2,610.41, P<0.05). 579 severe cases including 16 deaths were reported during 2012-2014, and the reported incidence rates of severe cases in the three years showed statistically significant differences (χ2 =431.355, P<0.05). The epidemic showed a clear seasonality, and the peak incidence was from April to July. More than 86% cases in each year were children aged 3 years or younger, and more cases occurred in males than in females. More than 86.12% cases in each year were reported in the scattered children. The results of pathogenic surveillance showed that the main pathogen in 2012 was human enteroviruses 71(HEV71) (61.71%), while those in 2013 and 2014 were other human enteroviruses (81.36% and 48.57% respectively). The main pathogens of the severe cases in 2012, 2013 and 2014 were HEV71(75.08%), other human enteroviruses (77.42%), and HEV71 and other human enteroviruses (50.00%, 40.00%). Conclusions There are statistically significant differences in the reported incidence rates and the severe case rates of HFMD among different years in Chenzhou City in 2012-2014. April-July in each year and scattered children aged 3 years or younger are the key points of HFMD prevention and control. The main pathogens show rapid dynamic changes in different periods, and the main pathogens of severe HFMD cases are not merely HEV71.
