The COVID-19 pandemic negatively impacted the 2019/20 WHO European Region influenza surveillance. Compared with previous 4-year averages, antigenic and genetic characterisations decreased by 17% (3,140 vs 2,601) and 24% (4,474 vs 3,403). Of subtyped influenza A viruses, 56% (26,477/47,357) were A(H1)pdm09, 44% (20,880/47,357) A(H3). Of characterised B viruses, 98% (4,585/4,679) were B/Victoria. Considerable numbers of viruses antigenically differed from northern hemisphere vaccine components. In 2020/21, maintaining influenza virological surveillance, while supporting SARS-CoV-2 surveillance is crucial.
COVID-19 大流行对 2019/20 年世卫组织欧洲区域流感监测造成了负面影响。与前 4 年的平均值相比，抗原和遗传特征分别下降了 17%（3,140 对 2,601）和 24%（4,474 对 3,403）。在已分亚型的甲型流感病毒中，56%（26,477/47,357）为 A(H1)pdm09，44%（20,880/47,357）为 A(H3)。在已定型的乙型流感病毒中，98%（4,585/4,679）为 B/Victoria。大量病毒的抗原与北半球疫苗成分存在差异。在 2020/21 年，维持流感病毒学监测，同时支持 SARS-CoV-2 监测至关重要。
