Forecasts of Flu Hospitalizations June 13, 2022

Updated June 14, 2022

Reported and forecasted new influenza hospitalizations as of June 13, 2022.

Interpretation of National Forecasts of New Hospitalizations

  • This week’s ensemble predicts that the number of new weekly confirmed influenza hospital admissions will likely decrease nationally, with 800 to 3,300 new confirmed influenza hospital admissions likely reported in the week ending July 9, 2022.
  • This week, 16 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 June 11 and forecasted new influenza hospital admissions per week over the next 4 weeks, through July 9. Effective February 2, 2022, hospitals are required to report laboratory-confirmed influenza hospitalizations to HHS Protect daily. Prior to this update, reporting influenza hospitalizations was optional (noted as grey in the above figure). See COVID-19 Guidance for Hospital Reporting and FAQs [680 KB, 52 pages] for additional details on this guidance.

State Forecasts

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.
