A comparative study of influenza surveillance systems and administrative data in England during the 2022-2023 season.

ABSTRACT: Accurate and representative surveillance is essential for understanding the impact of influenza on healthcare systems. During the 2022-2023 influenza season, the Northern Hemisphere experienced its most significant epidemic wave since the onset of the COVID-19 pandemic in 2020.
