摘要
目的:分析鄂尔多斯市2012年流感检测结果,为本地区流感预防控制提供科学依据。方法采用Real-time RT-PCR法对哨点医院采集的流感样病例咽拭子标本进行病毒核酸检测。结果共检测流感咽拭子标本281份,流感病毒核酸阳性35份,总阳性率为12.46%。其中乙型16份,占5.69%,季节性H3亚型15份,占5.34%,甲型H1N12份,占0.71%,甲型未分型2份,占0.71%。2012年1月~3月阳性率分别为11.36%、27.50%、37.50%,10月和12月阳性率均为5.00%,其它月份未检出阳性。结论监测显示鄂尔多斯地区流感流行季节主要为冬春季,流行毒株主要是乙型和季节性H3亚型。
