Face masks effectively limit the probability of SARS-CoV-2 transmission
This entire study seems to be centered around a theoretical, mathematical model, and I didn&#x27;t see any attempt to actually validate that model.<p>Basically, the authors seem to assume that the virus behaves according to their formulas, and show that under their assumptions, face masks work, but don&#x27;t actually prove that their assumptions match reality - or did I miss something?
