Flu Hospital Admissions: Week ending July 16, 2022

Interpretation of forecasts

• Reported and forecasted new influenza hospitalizations as of June 20, 2022.
• This week, 15 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 18 and forecasted new influenza hospital admissions per week over the next 4 weeks, through July 16. 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).
