[ Objective ] To analyze the distribution characteristics and epidemiological trend of hand-foot-mouth disease （HFMD） in Liuzhou City from 2009-2012, provide a scientific basis for making prevention measures of HFMD. [ Methods] The data of HFMD cases in Liuzhou City from 2009-2012, which were reported by the Disease surveillance information management system, were ana-lyzed. [ Results] A total of 65 735 HFMD cases were reported in Liuzhou City from 2009-2012, and there were 409 severe cases and 23 death cases. The annual reported incidence rate was 205.54/lakh, 437.94/lakh, 456.81/lakh and 624.42/lakh, respectively. The peak season was April to June, and the cases were found in all 11 counties/districts. The incidence rate in males was higher than that in females. 95.68% of patients were children under 5 years old. The scattered children and nursery children accounted for 67.79% and 28.95% respectively. Among 366 cases confirmed by laboratory examination, 71.86% were positive for enterovir-us 71 （ EV71 ）, 9.29% were positive for coxsackie virus A16 （ CoxA16 ）, and 18.85% were positive for other enteric virus. [ Conclusion] The incidence rate of HFMD shows a rising trend in Liuzhou City, so HFMD prevention and control can not be ig-nored. It is necessary to strengthen multi-sector cooperation, and improve the prevention and control among scattered children and nursery children, to reduce HFMD outbreak.
