摘要
目的了解新疆乌鲁木齐市2007-2008年麻疹暴发疫情流行病学特征,为改进控制工作提供依据。方法用描述性流行病学分析方法分析乌鲁木齐市2007年11月至2008年6月麻疹暴发疫情流行特征;运用1∶2病例对照研究方法分析麻疹暴发疫情的危险因素,并对病例管理、应急接种等干预措施效果进行评价。结果 0~4岁年龄组发病水平较高(报告发病率为773/10万),其中散居儿童占92%;15~30岁组发病水平仅次于0~4岁组,报告发病率为169/10万,其中学生病例占40%。医院暴露是<8月龄和>18岁组人群感染麻疹的影响因素,未接种麻疹减毒活疫苗(MV)是8月龄~17岁组感染麻疹的影响因素。结论医院暴露和未接种MV是导致此次麻疹暴发疫情流行的主要原因,控制医院内感染和切实作好MV免疫接种工作是控制麻疹暴发疫情的关键。
