Governments are taking a wide range of measures to tackle the COVID-19 outbreak. We aim to track and compare worldwide government responses to the coronavirus rigorously and consistently. Systematic information on which measures governments take, and when, can help us understand the responses in a consistent way, aiding efforts to fight the pandemic. Our team collects information on common policy responses, scores the stringency of such measures, and aggregates these into a Stringency Index. University of Oxford, Blavatnik School of Government
