Purpose
This week's ensemble predicts that the number of new weekly confirmed influenza hospital admissions will remain stable or have an uncertain trend nationally, with 300 to 2,900 new confirmed influenza hospital admissions likely reported in the week ending March 11, 2023.
Interpretation of forecasts
- Reported and forecasted new influenza hospitalizations as of February 28, 2023.
- This week, 20 modeling groups contributed 21 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. 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 influenza hospital admissions per week for 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.
