Objective To understand the epidemiological characteristics of hand-foot-mouth disease (HFMD) in Napo County, Guangxi Province, and to provide a scientific basis for making prevention and control measures. Methods Descriptive epidemiological methods were used to analyze HFMD case data reported in Napo County. Results A total of 1 560 HFMD cases were reported from January to October 2012, with an incidence rate of 763.92 / 100 000; 15 severe cases and no deaths were reported. There were 1,103 males and 457 females, which were significantly higher in males than in females (P <0.01). The highest prevalence was in children under 4 years of age with diaspora. The prevalence was mainly between May and July, 10 Month for the peak incidence. The positive rate of enterovirus nucleic acid in 33 etiological samples was 63.64% (21/33), of which 19 were enterovirus EV71, accounting for 90.48% (19/21) of the positive cases. The positive rates of CoxA16 and CoxA17 In 1 case, each accounted for 4.76% of the positive cases (1/21). Conclusion HFMD outbreak in Napo County, 2012, is in a high prevalence state. HFMD prevention and control in high incidence areas and diaspora should be emphasized.
