Currently, WHO Europe and ECDC’s February virus characterization report is available and describes available data from circulating viruses for the early weeks of the 2022-2023 influenza season.
Between weeks 36 and 39/2023, 8 virus was assessed for susceptibility to neuraminidase inhibitors and 7 to baloxavir marboxil. Phenotypically and/or genotypically, no markers associated with reduced susceptibility were identified.
