Non-pharmaceutical interventions have been key to containing the impact of the COVID-19 pandemic. This column examines whether the effectiveness of lockdowns on the virus’s spread and death toll has changed over the past year, using data from 152 countries from the onset of the pandemic through 31 December 2020. Initially, lockdowns are associated with a significant reduction in the spread of the virus and the number of related deaths, but this effect declines over time. Lockdown does not work as a continuous containment policy in the event of a protracted pandemic.
