During the 2018-2019 flu season, 24 different teams participated in the flu forecasting initiative, each submitting 38 different weekly forecasts. Los Alamos National Laboratory, led by Dr. Dave Osthus, provided the most accurate national-, regional-, and state-level influenza-like illness forecasts. This marks the first influenza season during which forecasts from Dr. Osthus’ team have been the most accurate. The Delphi group at Carnegie Mellon University, led by Dr. Roni Rosenfeld, provided the most accurate national-level hospitalization forecasts. This marks the fifth season during which forecasts provided by Dr. Rosenfeld’s team have been the most accurate.
