2008—2010年内蒙古自治区麻疹流行特征

Analysis on epidemiological features of measles in Inner Mongolia from 2008-2010

目的了解2008—2011年内蒙古自治区麻疹流行特点,为消除麻疹提供科学依据。方法根据内蒙古自治区传染病报告系统和年度麻疹发病统计表,对2008—2011年麻疹发病资料进行分析。结果 2008—2011年内蒙古自治区共报告麻疹病例4 873例,年均发病率为5.01/10万,2008年发病率最高,达10.90/10万;2011年发病率最低,为0.44/10万。各盟市均有病例报告,各月份均有发病,以3—7月份发病最多,占86.6%。发病年龄集中在大年龄组(≥15岁)和<1岁组病例,分别占病例总数的43.0%和22.3%。结论针对易感人群继续进行麻疹疫苗查漏补种可有效降低麻疹发病。

[Objective]To understand the epidemiological features of measles in Inner Mongolia from 2008-2011,provide scientific evidences for measles elimination.[Methods]Based on Inner Mongolia infectious disease reporting system and the annual statistics of measles,the data of measles from 2008 to 2011 were analyzed.[Results]During 2008-2011,a total of 4 873 measles cases were reported in Inner Mongolia with the average annual incidence rate of 5.01/lakh,while the incidence rate in 2008 was the highest（10.90/lakh）,and that in 2011 was the lowest（0.44/lakh）.The cases were reported in every city and league.The cases were found in every month,and most of the cases occurred March to July,which accounted for 86.6%.A majority of cases were children over 15 year-old and under 1 year-old,which accounted for 43.0% and 22.3% respectively.[Conclusion]The supplementary immunization of measles among susceptible population can remarkably reduce the incidence rate of measles.
