无锡市2004—2009年麻疹流行病学特征分析

Analysis on Epidemiological Characteristics of Measles in Wuxi during 2004-2009

目的了解无锡市2004-2009年麻疹流行病学特征，为制定防控新策略提供依据。方法对2004-2009年麻疹发病情况进行流行病学分析。结果2004-2009年麻疹年均发病率为5．52／10万，外来人口发病率高于本市人口，本市人口以20岁以上成人病例为主，外来人口麻疹病例集中在8月龄～6周岁年龄组儿童，发病均以无免疫史为主。结论外来人口存在免疫空白是导致麻疹发病率上升的主要原因。加强外来人口管理，杜绝免疫空白，是无锡市消除麻疹亟需解决的主要问题。
