Type: article

Abstract: Influenza activity peaks in southern (59.62%) and northern China (57.60%) during the 2022/2023 season reached the highest levels in the past 10 years. The 2023/2024 season witnessed a longer duration of the winter-spring epidemic weeks and a higher disease burden compared with previous high-epidemic years. The A(H3N2), A(H1N1)pdm09, and B/Victoria lineages alternated among the predominant circulating strains from the 2022/2023 season to the 2024/2025 season. After the 2022/2023 and 2023/2024 seasons of disruption and fluctuation, influenza in the 2024/2025 season has reverted to its previous epidemic pattern.
