This paper, sent to me by someone in the biosciences field, is fascinating.
It purports to claim that coronavirus, but not rhinoviruses or influenza, may be stopped by surgical masks. That is, it’s one of those that people would cite as “source control.”
Well, actually not, if you read the study itself.
Because the entire premise behind source control for something like Covid is that unsuspecting people do shed the virus from their mouth and nose and this is the primary source vector for infection.
As I’ve noted I haven’t believed this since the outbreak began for several reasons, all of which are rooted in physics and basic logic.
