The 2023 2024 influenza season saw low vaccination uptake, tens of thousands of deaths, and elevating concern over the pandemic potential of the worst avian influenza outbreak in the nation’s history.
2023 2024 United States Flu Season Preliminary In Season Severity This study examines trends in influenza incidence, vaccination rates, and mortality in the united states from the 2018–2019 through to the 2023–2024 influenza seasons. Continuing this trend, the first half of the 2023–2024 season saw classic influenza a circulation, but was marked by the return of typical late season influenza b circulation for the first time since the onset of the pandemic, highlighting persistent shifts in influenza dynamics. Using healthcare encounters data from health systems in 8 us states, we evaluated influenza vaccine effectiveness (ve) against influenza associated medical encounters from october 2023 to april 2024. This summary of influenza disease burden, influenza disease burden prevented by vaccination and influenza severity assessment for the 2023 2024 season is an addendum to the 2023 2024 influenza activity report.
