Forecasts of Flu Hospitalizations April 6, 2022
Updated April 14, 2022
Reported and forecasted new influenza hospitalizations as of April 4, 2022.
Interpretation of National Forecasts of New Hospitalizations
- 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 800 to 5,500 new confirmed influenza hospital admissions likely reported in the week ending April 30, 2022.
- This week, 14 modeling groups contributed one or more forecasts that were eligible for inclusion in the new hospitalization ensemble forecasts for at least one jurisdiction. Contributing teams are listed below.
- Ensemble forecasts combine diverse independent team forecasts into one forecast. They have been among the most reliable forecasts in performance for previous influenza and COVID-19 forecasts, but even the ensemble forecasts may not reliably predict rapid changes in the trends.
- The figure shows the number of new confirmed influenza hospital admissions reported in the United States each week from September 26 through April 2 and forecasted new influenza hospital admissions per week over the next 4 weeks, through April 30.
State-level forecasts show the predicted number of new influenza hospital admissions per week for the next 4 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.
