Data obtained from monitoring cases of severe influenza, cases of vaccinated individuals, and unique cases were used to describe influenza viruses that circulated in Russia in the 2018–2019 epidemic season. A high proportion of the mutations D222G/N in A(H1N1)pdm09 HA was detected in fatal cases. Viruses of the B/Victoria lineage with deletions in HA were detected in Russia, and a reassortant seasonal influenza A(H1N2) virus was identified. A C-terminal truncation in the NS1 protein was detected in a substantial proportion of A(H3N2) viruses.

2018-2019年俄罗斯严重季节性流感病例和季节性A（H1N2）检测。

通过监测严重流感病例，接种疫苗病例和特殊病例获得的数据被用来描述俄罗斯在2018-2019流行季节传播的流感病毒。在致命病例中，在A（H1N1）pdm09 HA中检测到很高比例的D222G / N突变。在俄罗斯检测到B / Victoria谱系中HA缺失的病毒，并鉴定了重配的季节性甲型H1N2流感病毒。在很大比例的A（H3N2）病毒中检测到NS1蛋白的C端截短。
