😷Masks have been found to be very protective against the virus that causes #Covid, esp. N95:

N95 masks are most effective at slashing the amount emitted by infected people, acc to a new Univ. of MD-led study.

"Duckbill” N95 masks scored highest in the study *measured the exhaled breath of participants who were tested both masked & unmasked to measure comparative outputs of SARS-CoV-2. The inexpensive masks, which have 2 head strps -captured 98% of exhaled virus.
