2007-2011年承德市双桥区麻疹监测分析

Surveillance on Measles in Shuangqiao District of Chengde City,2007-2011

目的了解河北省承德市双桥区麻疹疫情动态和监测系统运行情况,为制定防治工作重点提供参考依据。方法分析双桥区2007-2011年麻疹监测系统上报的疑似麻疹病例个案调查表。结果全区2007-2011年报告疑似麻疹199例,经血清学检测确诊135例,其中区外流动人口83例,占确诊总病例数61.5%,本区病例52例,占确诊总病例数的38.5%。本地确诊病例年平均发病率3.12/10万,流动人口确诊病例年平均发病率4.99/10万。发病年龄最小4个月,最大45岁。135例麻疹病例中,有麻疹疫苗接种史的42例(31%);未免疫的63例(47%),免疫史不详的30例(22%)。结论麻疹发病以婴幼儿和成人为主,流动人口发病率较高是不容忽视的群体。应加强8月龄儿童麻疹类疫苗接种的及时率,加大流动儿童的规范化免疫成功率,控制成人麻疹疫情。

Objective To study the epidemic status of measles and the operational condition of the surveillance system,and to provide references for formulating targeted prevention and control measures.
