Masks wouldn't even bring BA.2 to BA.1 transmissibility. > According to early research, BA.2 is roughly 30% to 60% more transmissible than BA.1 https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#Affected_countries_and_transmissibility https://en.wikipedia.org/wiki/SARS-CoV-2_Omicron_variant#Aff...
