一起麻疹局部流行疫情的分析

Analysis of a focal prevalence of measles

目的分析本起麻疹流行的流行病学特征及意义,为防制工作提供借鉴。方法对流行期间发生的85例患者的相关调查资料进行流行病学分析。结果85例中,实验室确诊43例,临床诊断42例。年龄分布为：1岁内婴幼儿16例(18.8%),1～6岁22例(25．9%),7～15岁10例(11.8%),16岁以上37例(43．5%)。其中27例接种过麻疹疫苗。结论本起麻疹流行与易感人群增多及免疫力下降有关,特别是流动人口的麻疹免疫水平偏低；因此,在重视婴幼儿麻疹基础及强化免疫的同时,应加强成人麻疹疫苗的补种工作。
