In this project, we aim to combine our existing frameworks for generating infectious disease forecasts and scenario-based projections. Next, we will apply them specifically to seasonal influenza during the 2022-23 season. The forecasting pipeline incorporates various statistical and machine learning methods and is being combined through a phase-informed ensemble. Scenario-based projections are generated through mechanistic metapopulation models using age-stratified and spatially explicit models. The project will also leverage our work developing meaningful indicators of disease activity which will provide useful insights for policymakers.
We find that phase-informed ensembles are more robust across the different epochs of the COVID-19 pandemic than a traditionally trained ensemble. We also find that using auxiliary sources, such as search activity and outpatient syndromic surveillance leads to more robust ensembles. These findings were reported in a series of papers at the IAAI 2022 and IEEE BigData 2022 conferences. The latter was recognized as the Best Paper submitted.
