Potential scenarios for the progression of a COVID-19 epidemic in the European Union and the European Economic Area, March 2020

Two months after the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the possibility of established and widespread community transmission in the European Union and European Economic Area (EU/EEA) is becoming more likely. We provide scenarios for use in preparedness for a possible widespread epidemic. The EU/EEA is moving towards the ‘limited sustained transmission’ phase. We propose actions to prepare for potential mitigation phases and coordinate efforts to protect the health of citizens.
