深圳市2008～2009年上半年手足口病流行病学发病特征及预防控制策略分析

Analysis on epidemiologic characteristics and control strategies on hand,foot and mouth disease in Shenzhen

目的对2008年～2009年6月深圳市手足口病病例的基本流行病学特征进行分析,为研究该病重点人群和预防控制策略提供基础信息。方法采用SPSS 16.0对2008年1月～2009年6月通过中国疾病预防控制系统报告的深圳市手足口病病例进行核实和分析。结果发病曲线显示深圳市手足口病报告从2008年3月下旬至4月份开始增加,高峰持续到7月中旬。2008年10、11月份出现发病次高峰。在全部12112例病例中,5岁及以下年龄组占92.5%。其中1岁组男性2019例,占全部病例的16.7%。2008年～2009年6月,发病主要集中在散居儿童。2008年发病至诊断的时间平均为1.86d(s=2.44),2009年为1.58d(s=2.03)。结论手足口病已成为深圳市公共卫生的挑战之一,预防控制策略应考虑手足口病的高危人群和季节性发病高峰。
