Bob,
Are you suggesting that the science on masks helping to prevent the spread of Covid is not proven science at this point?
Rich: No, but now that you mention masks, studies of the use of masks to protect against the FLU VIRUSES have almost uniformly established that masks play no significant role in preventing spread of the flu.
This fact may be a non sequitur as applied to a novel coronavirus, but it is one of the chief reasons, IMO, why Fauci first stated (generally speaking) that masks were not necessary.
Why he later changed his mind and decided to start recommending the wearing of masks is not clear to me.
