Wearing Masks While Inside Benefits Everyone

The U.S. CDC published a scientific briefing on November 10, 2020, which concluded 'experimental and epidemiological data support community masking to reduce the spread of the SARS-CoV-2 coronavirus. Multi-layer cloth masks have been found to both block up to 70% of fine droplets (10 microns) and limit the forward spread of those particles that are not captured.

The CDC says 'the relationship between source control and personal protection is likely complementary and possibly synergistic so that individual benefit increases with increasing community mask use.'

Note: none of the studies reviewed for this CDC briefing focused on the benefits or risks to a person when wearing a mask outside.
