阜阳市2009～2011年麻疹监测与消除麻疹效果分析

Analysis on measles surveillance and effect of measles elimination in Fuyang,2009-2011

目的分析阜阳市2009～2011年麻疹监测结果与消除麻疹干预效果,为如期消除麻疹提供理论依据。方法采用描述流行病学方法对麻疹监测数据进行统计分析。结果 2009～2011年麻疹监测系统报告疑似麻疹1 447例,实验室诊断为麻疹394例,临床诊断399例,≥15岁及﹤18个月龄儿童发病较高,分别占25.3%和28.6%。18个月龄内儿童发病率逐年增高;8个月龄以上人群未免疫接种和免疫史不详者占57.7%,应免疫2剂次无确切全程免疫史的占85%以上。结论阜阳市消除麻疹干预措施效果显著,通过麻疹疫苗强化、查漏补种等,麻疹发病率逐年下降,2011年达历史最低水平;≥8个月龄人群麻疹疫苗漏种或不全程接种是麻疹发病的主要因素;﹤8个月龄和﹥15岁人群属免疫空白和薄弱人群,推行育龄妇女和15岁以上麻疹疫苗强化免疫工作值得探讨。
