An immunocompromised child with influenza A/H3N2 virus infection, treated with oseltamivir from day 1, had nasal swabs taken on days 1, 4, 7, and 10 of the illness. Pyrosequencing showed increasing proportions of viruses with R292K (neuraminidase gene) and G186D (hemagglutinin gene) mutations, resulting in a viral load rebound by day 10.
一名感染甲型H3N2流感病毒的免疫功能低下儿童,从发病第1天开始接受奥司他韦治疗,在发病第1、4、7和10天采集了鼻拭子。焦磷酸测序显示,具有R292K(神经氨酸酶基因)和G186D(血凝素基因)突变的病毒比例不断增加,导致到第10天时病毒载量反弹。
