Predicted daily COVID-19 mortality over time in countries with and without facemask policy.

Note: This figure illustrates the daily mortality trend. The rate of increase of daily mortality per million population is significantly lower in countries with a facemask policy compared to the rate of increase in countries without a facemask policy. The illustration shows the gap between countries with and without facemask policy widens across time.
