目的了解本地区七种常见呼吸道病毒临床分布特征,旨在为呼吸道病毒的预防、治疗提供帮助。方法随机选取2 001例呼吸科住院患者样本,采用直接免疫荧光法进行呼吸道病毒抗原检测。结果 2 001例患者样本中,共检测出629例阳性病毒,阳性率为31.43%,阳性率前三位的病毒依次为甲型流感病毒(FluA)、呼吸道合胞病毒(RSV)、乙型流感病毒,分别为12.14%、9.90%和3.80%,而副流感病毒II型检出率最低,为0.50%。冬、春季节为呼吸道病毒高发季节,其中一月和二月的检出率高达56.91%和43.15%;而夏、秋季节检出率相对较低,六月的检出率仅为7.00%;1岁年龄组病毒阳性检出率最高,且随年龄增大,阳性检出率明显降低。结论冬、春季节是呼吸道病毒的高发季节;FluA和RSV是呼吸道感染中最常见的病毒;1岁年龄组病毒阳性检出率最高。 相似文献
