摘要
目的 探讨内蒙古自治区2010年至2012年流感流行特征.方法 在全区选择19家医院为哨点医院,统计监测科室的流感样病例数和门诊就诊人数,计算流感样病例(ILI)就诊百分比.每周采集流感样病例呼吸道标本5~10份,采用鸡胚进行病毒分离;采用EpiData 2.1编制的数据库,应用Spss 10.0 for windows软件进行统计分析,统计指标包括绝对数、率、构成比等.结果 2010年至2012年,累计报告流感样病例74 169例,5岁以下,5~ 10岁,10~15岁,25~60岁以及60以上分别占51.8%、20.8%、6.4%、15.4%和5.5%;流感样病例就诊比例最高值分别出现在7周、5周和52周,均值分别为6.4%、2.3%和2.7%.共检测10031份ILI呼吸道标本,阳性率为12.0% (1203/10031).阳性标本中B型流感病毒占43.9%(528/1203).结论 内蒙古2010年至2012年流感流行高峰出现在冬春季节,流行毒株以B型为主,低年龄组儿童是高发人群.
