摘要 目的探讨湖北省襄阳市手足口病(hand-foot-and-mouth disease,HFMD)的流行病学特征,为科学防治HFMD提供依据。方法对2012-2013年湖北襄阳市HFMD疫情资料进行描述性流行病学分析,并对主要病原人肠道病毒71型(enterovirus 71,EV71)VP1区利用one-step逆转录-聚合酶链反应方法扩增,进行测序及系统发育分析。结果襄阳市手足口病全年各时段均有病例报告,2012年手足口病发病整体水平高于2013年,发病高峰均约为4-6月。病例主要集中在0-5岁的散居儿童和托幼儿童,1-3岁儿童组发病率相对较高。男性发病明显高于女性,男女性别比为1.58∶1。手足口病病原检测仍以EV71型病毒为主,襄阳市14株EV71型流行株VP1基因的核苷酸序列和氨基酸序列的同源性分别为97.3%-99.3%和98.7%-100%。系统发育分析显示与中国大陆其他地区EV71型毒株均属于C4基因型的C4a基因亚型。结论湖北襄阳市手足口病发病有明显的季节性,存在地区、年龄、性别差异。主要病原为EV71型,其基因型为C4a亚型。通过在高发季节对重点地区、重点人群采取防控措施以降低手足口病的暴发与流行。
