A Center for Disease Control and Prevention report released Friday found that the effects of mask mandates and restaurant restrictions on coronavirus cases and deaths were smaller than people thought.

The CDC examined county cases and deaths from March to December 2020 in the first 100 days after masks were mandated and restaurants could reopen.

Counties that issued mask mandates saw cases drop by half a percentage point in the first 20 days of the mandate. Deaths dropped by 0.7 percentage points during the same time period.
