Masks are part of the equation, not a magic bullet. I use my mask when in crowded moments (2 is company, threes a crowd).
Nope. Either masks reduce the viral load or they dont. If you are going to advocate that you dont need masks because they dont work ...then dont require them on public transport.
I personally believe they are part of the equation..but this story says they dont work....but uh...we are going to make them mandatory anyway on public transport.
