Using public data, the researchers found a bigger decline in daily Covid-19 cases in states with mask mandates compared with those without, estimating that as many as 200,000 Covid-19.

Eric Boehm We show that mask mandates are associated with a statistically significant decrease in new cases (-3.55 per 100K), deaths (-0.13 per 100K), and the proportion of hospital admissions (-2.38 percentage points) up to 40 days after the introduction of mask mandates both at the state and county level. We used state-level data on mask wearing policy for the general public and on proportion of residents who stated they always wear masks in public. The United States, as of Friday, posted a seven-day moving average of 62,555 new COVID-19 cases reported daily, according to data from the Centers for Disease Control and Prevention.The last time .
