Article: 54/3502

The European Centre for Disease Prevention and Control (ECDC) periodically publishes influenza characterisation reports, giving an overview of circulating influenza viruses. These reports provide details on the current vaccine strains, summarise the development of the viruses since the last report and closely follow the main developments for the ongoing influenza season.

On 24 August 2020, the ECDC published the ninth virus characterisation report for the 2019 to 2020 influenza season. As of week 30 in 2020, a total of 164,887 influenza detections had been reported across the World Health Organization (WHO) European Region. Of these, 73% were type A viruses, with A(H1N1)pdm09 prevailing over A(H3N2), and 27% type B viruses, with 4,479 (98%) of 4,505 ascribed to a B/Victoria lineage.
