Epidemiological Characteristics of Mumps in Inner Mongolia,2005-2014

目的分析内蒙古流行性腮腺炎（流腮）的流行病学特征,为进一步防控爆发疫情提供依据。方法采用描述流行病学方法对流腮流行特征变化进行分析。结果 2005~2014年共报告流腮病例42 770例,年发病率在7.75/10万~44.12/10万之间,共报告爆发疫情42起,均发生在学校,经检测分析是由F基因型腮腺炎病毒引起。每年4~7月份和11~翌年1月为发病高峰。以5~14岁人群发病率最高,0~9岁儿童中发病高峰的年龄出现前移。学生占71.09%,托幼儿童占13.89%,散居儿童占7.45%。结论内蒙古流腮发病和流行以儿童特别是中小学生为主,应加强学校疫情监测,开展入学儿童的查漏补种或推广2剂次含腮腺炎成分疫苗的接种。

Objective To analyze the epidemiological characteristics of mumps in Inner Mongolia and provide evidence for further prevention and control of outbreaks.Methods Descriptive epidemiological methods were used to determine characteristics of mumps.Results 42770 mumps cases were reported from 2005 to 2014; the annually-reported incidence rates ranged 7.75-44.12 per 100000 population.Forty-two mumps outbreaks occurred in schools.There were two seasonal peaks-from April to July and from October to next January.The highest incidence was among 5-14 year olds.The seasonal peak among the 0-9 year old group was earlier than the average peak occurrence.Among all cases,students accounted for 71.09%,nursery children 13.89%,and scattered living children 7.45%.Conclusions Most cases and outbreaks of mumps in Inner Mongolia occurred among children,especially primary and middle school students.Disease surveillance in schools should be strengthened,the school entry vaccination record check should be strengthened,and consideration should be given for a 2-dose mumps-containing vaccine immunization strategy.
