深圳市罗湖区1998～2004年麻疹监测分析

目的 了解罗湖区开展麻疹监测以来麻疹流行病学特点。方法 对1998-2004年麻疹疫情和监测系统运转情况进行分析。结果 1998-2004年全区报告麻疹疑似病例670例，实验室和临床确诊378例，年平均发病率为7．79／10万，其中户籍人口年平均发病率为1．79／10万。发病高峰集中在每年3～7月，呈现低年龄组儿童和青壮年居多的“双相移位”现象，14．55％的病例无麻疹疫苗免疫史，68．78％的病例接种史不详。经分子生物学检测初步显示目前流行的麻疹病毒株为H1基因型。全区麻疹监测系统运转基本正常，敏感性较高，麻疹发病已控制在较低的水平。结论 为加速控制麻疹，今后要提高儿童麻疹疫苗的基础免疫接种率和成人麻疹疫苗复种。
