Note: The stringency level is a composite index of nine policy measures: school closing; workplace closing; cancel public events; restrictions on gatherings; close public transport; stay-at-home requirements; restrictions on internal movement; international travel restrictions; and public info campaigns. The index ranges from 0 to 100. A higher index indicates a higher stringency. The size of a bubble is proportional to a country’s total number of cases. Countries below a tests-per-million threshold of 20,000 are excluded to reduce under-detection bias, with the exception of China. A similar picture is observed with the total number of deaths. Data as of May 20, 2020.
