The Data Against Corona Taskforce is an initiative set up by the Belgian Ministers of Health and Digital Agenda to analyze the spread of COVID-19 through telecommunications and health data. The task force, which includes data scientists, data privacy experts, epidemiologists, bioethicists, a medical lawyer and others, will analyze data from the telecommunications providers Proximus, Telenet and Orange. This analysis will inform government actions to control spread and communications efforts through BE-Alert, the Belgian federal government’s emergency alarm system. All work is compliant with GDPR and overseen by an ethical council.
