Flu Hospital Admission as of May 4, 2024
Flu Hospital Admissions as of April 17, 2024
What to know
This week's ensemble predicts that the number of new weekly laboratory confirmed influenza hospital admissions will likely decrease nationally, with 890 to 6,200 laboratory confirmed influenza hospital admissions likely reported in the week ending May 4, 2024.
Interpretation of forecasts
* Reported and forecasted new influenza hospital admissions as of April 17, 2024.
* This week, 24 modeling groups contributed 29 forecasts that were eligible for inclusion in the ensemble forecasts for at least one jurisdiction. Contributing teams are listed below.
* Ensemble forecasts combine forecasts from diverse models into one forecast. They have been among the most reliable forecasts in performance for previous influenza and COVID-19 forecasting efforts, but even the ensemble forecasts may not reliably predict rapid changes.
* The figure shows the number of new laboratory confirmed influenza hospital admissions reported in the United States each week from September 1 through April 13 and forecasted new influenza hospital admissions per week for this week and the next 2 weeks, through May 4. Hospitals are required to report daily laboratory-confirmed influenza hospitalizations to the National Healthcare Safety Network (NHSN). COVID-19 Guidance for Hospital Reporting and FAQs has additional details on this guidance.

State Forecasts
State-level forecasts show the predicted number of new laboratory confirmed influenza hospital admissions per week for this week and the next 2 weeks by state. Each state forecast figure uses a different scale due to differences in the number of new influenza hospital admissions per week between states and only forecasts included in the ensemble are shown. Plots of the state-level ensemble forecasts and the underlying data can be downloaded below.

Unlike CDC’s traditional influenza (flu) surveillance systems, which measure flu activity after it has occurred, flu forecasting provides information about the future, allowing CDC to plan ahead and potentially reduce the impact of flu.
