The virus quickly spread through Europe, and according to the European Centre for Disease Prevention and Control (ECDC), there were many millions of cases and significant numbers of COVID-19-related fatalities in Europe. The spread occurred in various time waves in the period 2020–2021 and with variable epidemiology across European countries.
