Interpretation of forecasts
- Reported and forecasted new influenza hospital admissions as of March 20, 2024.
- This week, 25 modeling groups contributed 30 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 March 16 and forecasted new influenza hospital admissions per week for this week and the next 2 weeks, through April 6. 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.
