目的分析海珠区2008—2011年手足口病(HFMD)的流行病学特征,为防控提供依据。方法对国家疾病预防控制信息系统报告的手足口病例进行分析。结果海珠区2008—2011年报告HFMD的发病率逐年上升,全区各行政街道均有病例,无死亡病例报告。各年度流动人口密集区发病率均高于非流动人口密集区;每年的4～7月和9～11月出现2个高峰期,发病有明显的季节性和年龄、性别差异;各年度男性发病数均高于女性,发病以散居儿童为主,≤4岁者占90.0%,暴发病例多为幼托儿童;病原主要为EV71和CoxA16。结论海珠区HFMD流行形势较严峻,应密切关注发病高峰时期的疫情动态,防控的重点是4岁以下散居和幼托儿童,应进一步对儿童抗体水平与HFMD的关系进行研究,加强疫苗开发力度,才能真正有效地控制疫情发生。
Objective To analyze the epidemiological characteristics of hand-foot-mouth disease (HFMD) in Haizhu District from 2008 to 2011 and provide the basis for prevention and control.
