安徽省2009年麻疹减毒活疫苗补充免疫活动效果评估

Effectiveness Assessment of the Supplementary Immunization Activities for Measles Attenuated Live Vaccine in Anhui Province in 2009

目的对安徽省2009年麻疹减毒活疫苗(Measles Attenuated Live Vaccine,MV)补充免疫活动(Supplem entary Immunization Activities,SIA)的流行病学效果进行评估,为消除麻疹提供参考。方法 采用描述流行病学方法 ,对安徽省2009年MVSIA前后的相关数据进行统计分析。结果安徽省于2009年10月,对全省8月龄～14岁儿童开展MVSIA。SIA后的2010年,安徽省麻疹发病数和发病率均降至2004年以来的最低水平,分别为439例和0.72/10万;削平了麻疹发病高峰;2010年≤14岁各年龄别麻疹发病率均比2009年大幅度下降。结论适时开展高质量的MVSIA,能有效控制麻疹流行,减少麻疹发病。MVSIA作为常规免疫的补充,是消除麻疹的重要策略之一。

Objective To evaluate the effect of measles attenuated live vaccine （MV） supplementary immunization activities （SIAs） in Anhui province in 2009, and to provide the reference for measles elimination. Methods Collecting measles epidemiology data before and after the MV SIA of 2009. Analyze the data with descriptive epidemiology. Results The MV SIAs in Anhui province were implemented in the October of 2009. The target population of the SIAs are the children aged from 8 months to 14 years. In 2010, both the number of reported measles cases and the measles incidence dropped to the lowest level since 2004, which were 439 cases and 0.72/100,000 respectively. The measles incidence of each age group among the children of 0-14 years old in 2010 dropped a lot comparing with that of 2009. Conclusions Carrying out high quality of SIAs at suitable time can control the epidemic of measles quickly, and decrease measles morbidity. Being a supplementary method for routine immunization, SIA is one of the important strategies to eliminate measles.
