Tóm tắt :

31 p. The November 2022 characterization report was the second report for the 2022-2023 influenza season. As of week 52/2022, 109 321 detections had been reported. Of these detections, 94% were type A viruses, with A(H3N2) and A(H1N1)pdm09 showing near equal proportions, 51% and 49% respectively, and 6% type B of which 707 were ascribed to a lineage, with all being B/Victoria. This represents a 5-fold increase in detections compared to the 2021-2022 season, despite only a modest increase (5%) in the number of samples tested. The epidemic threshold of 10% positivity within sentinel specimens was crossed in week 45/2022.
