The Coronasurveys team (https://coronasurveys.org/) led by Antonio Fernandez from IMDEA, and involving Davide Frey from the WIDE team, were finalists in the Facebook Symptom Data Challenge (https://www.symptomchallenge.org/). They developed forecasting methods for the number of COVID-19 cases based on the signals collected by the FB Symptom Survey and by coronasurveys.org.
Congratulation to everyone involved!
