Note
This repository archives the forecasts computed during season 2023/2024. To explore forecasts for the current season visit the new RespiCast Syndromic Indicators repository.
The European Flu Forecasting Hub collates weekly forecasts on Influenza-Like-Illness (ILI) incidence in EU/EEA countries. To view the latest forecast visit the Hub Website.
During the influenza season, participating teams submit weekly probabilistic forecasts from their models regarding ILI incidence for the upcoming four weeks. This data is communicated every week by the ECDC through the ERVISS report. Data is updated generally on Friday, and it reports ILI incidence related up to the previous week. Forecast submission opens right after updated data are uploaded to this repository and closes on the next Wednesday at 23:59 CET. In the event of changes in the timelines of data availability, the day of the week for forecast submissions may be adjusted accordingly. In such instances, participants will receive notifications at least one week in advance. Following the submission deadline, forecasts and the ensemble are published on the Hub website every Thursday. They cover the preceding week (which lacks consolidated public data), the current week, and the two subsequent weeks.
The 2023-2024 forecasting season has ended on May 1st. 2024-2025 season opens next fall.
This is a brief outline for anyone considering contributing a forecast. For a detailed guide on how to structure and submit a forecast, please read the technical Wiki or watch the following tutorial video on how to submit your first forecast:

After completing the preceding steps, you are now prepared to submit your first forecast. We are currently focused on the forecast target of Weekly ILI Incidence (notified cases per target-data folder of this repository.
Forecast can be submitted to the Hub either via GitHub website or GitHub Command Line. The submission will trigger automatic validations that check the forecast have the required format. Incorrect formatting will lead to errors, resulting in submission failure. If this occurs, kindly review and rectify your format.

The European Flu Forecasting Hub is part of the European Respiratory Diseases Forecasting Hubs consortium (RespiCast), which combines multiple forecasting hubs for several respiratory disease indicators, including influenza-like-illness (ILI), acute respiratory infection (ARI), and COVID-19. This consortium of hubs is run in collaboration between the European Centre for Disease Control and Prevention (ECDC), the ISI Foundation, and the London School of Hygiene & Tropical Medicine. Teams from anywhere in the world are invited to submit weekly forecasts for one or more disease indicators and for one or more countries. For more information visit the RespiCast website
