Aim To survey the epidemiological features of hand-foot-mouth disease （HFMD）in Guangxi and provide scientific evidence for formulating HFMD control strategies. Methods The descriptive epidemiological method was applied to analyze the epidemiological and laboratory data of HFMD epidemics in Guangxi. Results Guangxi reported an accumulative total of 45 644 HFMD cases in 2009,with an incidence rate of 94.77/100 000,which mainly occurred during March-June. The cities of Nanning,Liuzhou and Fangcheng were among the regions with highest incidence rates. The majority （90.52%）of cases were found sporadically in children under 5 years old. The ratio between males and females was 1.78：1.Coxsackievirus A16 accounted for 61.3% of the total 222 laboratory-confirmed cases. Conclusion Significant seasonal,regional,gender and age variations have been noticed. Therefore,intensified surveillance and effective control are the key for prevention and control of HFMD.
