为了解我国大陆流行的季节性流感病毒对抗流感病毒药物的敏感性,本文对2023-2024流感监测年度分离的季节性流感病毒进行了神经氨酸酶抑制剂和巴洛沙韦的耐药检测。基于表型方法检测的5 341株季节性流感毒株中,9株A(H1N1)pdm09亚型对Oseltamivir敏感高度降低,NA基因上有H275Y位点的变异;2株B/Victoria系对Oseltamivir和Zanamivir敏感性均降低,NA基因上分别有I348T和D197N位点的变异。基于基因型方法检测的1 207株季节性流感毒株中,1株A(H1N1)pdm09亚型在PA基因上有K34R和E198K位点的变异,2株A(H3N2)亚型在PA基因上有L28P位点的变异,提示对巴洛沙韦的敏感性降低。因此,上述监测数据表明2023-2024年我国大陆流行的季节性流感病毒总体上对神经氨酸酶抑制剂和巴洛沙韦敏感,这两类药物依然是治疗流感病毒感染的适当选择,而密切监测病毒对抗病毒药物的敏感性是必要的。
