目的分析2012—2014年手足口病季节性特征及病原菌变化情况,为地方卫生部门制定政策提供参考。方法收集中国疾病预防控制信息管理系统中本市手足口病报告数据,采用集中度与圆形分布法进行分析。结果 2012—2014年共报告报告手足口病578例,2012、2013、2014年分别为144例(96.57/10万)215例(145.12/10万)、219例(156.65/10万);4—7为发病高峰期,分别占63.89%(92/144)、59.07%(127/215)、52.97%(116/219),共占57.96%(335/578);3年平均角为162.51°,平均角标准差为92.12°,可信区间102°~254.3°。结论本市手足口病有着明显的季节性特征,病原体优势毒株发生了变化,应加强监测分析,以预防控制手足口病的爆发与流行。
Objective To analyze the seasonal characteristics of hand-foot-mouth disease and the changes of pathogenic bacteria in 2012-2014 so as to provide references for local health departments to formulate policies. Methods Data of hand, foot and mouth disease reported in China Disease Prevention and Control Information Management System were collected and analyzed by concentration and circular distribution method. Results A total of 578 HFMD cases were reported in 2012-2014, including 215 cases (145.12 / 100000) and 219 cases (156.65 / 100000) in 144 cases (96.57 / 100000) in 2012, 2013 and 2014 respectively. 7 accounted for 63.89% (92/144), 59.07% (127/215) and 52.97% (116/219), respectively, accounting for 57.96% (335/578) of the peak incidence. The average angle of three years was 162.51 °, The standard deviation of the average angle was 92.12 °, and the confidence interval was 102 ° ~ 254.3 °. Conclusion Hand, foot and mouth disease in this city has obvious seasonal characteristics. The dominant strains of pathogens have changed. Monitoring and analysis should be strengthened to prevent and control the outbreak and epidemic of HFMD.
