# European COVID-19 Forecast Hub - 2021/2024

> [!NOTE]
> This repository archives the forecasts computed from 2021 to the fall of 2024. To explore forecasts for the current season visit the new [RespiCast Covid19 repository](https://github.com/european-modelling-hubs/RespiCast-Covid19).

We are aggregating forecasts of new cases and deaths due to Covid-19 over the next four weeks in countries across Europe.

##### Latest forecasts

* View the [current forecasts](https://covid19forecasthub.eu/visualisation)
* We publish a weekly [evaluation](https://covid19forecasthub.eu/reports) of current forecasts
* Raw forecast files are in the [data-processed](https://github.com/european-modelling-hubs/covid19-forecast-hub-europe/tree/main/data-processed) folder

##### README contents

- [About Covid-19 forecast hubs](#about-covid-19-forecasting-hubs)
   - [European forecast hub team](#european-forecast-hub-team)
   - [Data license and reuse](#data-license-and-reuse)

## Quick start

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](../../wiki).

#### Set up

Before contributing for the first time:
- Read the guide for [preparing to submit](../../wiki/Preparing-to-submit)
- Create a [team directory](../../wiki/Creating-a-team-directory)
- Add your [metadata](../../wiki/Metadata) and a [license](../../wiki/Licensing)

###### Evaluating and ensembling

After teams have submitted their forecasts, we create an ensemble forecast. Note that the ensemble only includes the forecasts that completely match the standard format (for example those with all the specified quantiles). See the [inclusion criteria](../../wiki/Ensembling-and-evaluation) for more details.

We also publish some weekly evaluation across forecasting models.

## About Covid-19 forecasting hubs

This effort parallels forecasting hubs in the US and Germany. We follow a similar structure and data format, and re-use software provided by the ReichLab.

- The [US COVID-19 Forecast Hub](https://github.com/reichlab/covid19-forecast-hub) is run by the UMass-Amherst Influenza Forecasting Center of Excellence based at the [Reich Lab](https://reichlab.io/).

- The [German and Polish COVID-19 Forecast Hub](https://github.com/KITmetricslab/covid19-forecast-hub-de) is run by members of the [Karlsruher Institut für Technologie (KIT)](https://statistik.econ.kit.edu/index.ph) and the [Computational Statistics Group at Heidelberg Institute for Theoretical Studies](https://www.h-its.org/research/cst/).

### European forecast hub team

This repository was created by [Epiforecasts](https://epiforecasts.io), supported by grant funding from the [European Centre for Disease Control and Prevention (ECDC)](https://www.ecdc.europa.eu/). It was based on and supported by members of the US, and German and Polish Forecast Hubs and is now maintained by the ECDC.

Direct contributors to this repository include (in alphabetical order):
