Studies, expert's guidance, and anecdotal evidence are all over the map on this. Yes, I know, the studies that disagree with your position are flawed and the experts that disagree are quacks. The problem is, that statement applies equally to both sides of the argument.


Arguing that mask are worthless is foolish. Arguing that masks will save the world is foolish. Arguing that without masks we are all doomed is foolish.

Masks can help, if even a little bit, and are an important part of an overall strategy but that must also include avoiding high risk activities.

The hope is that if both people are wearing a mask that the viral load that is received from someone that might be positive is less than if neither is wearing a mask and exposed to a full viral load of the virus. There have been discussions that the amount of viral load someone receives may determine how sick they become.
