Also, well fitted N95 style masks are very different from a loose mask around the face.

Still makes a world of difference though, especially because your mask (unless N95) isn’t for you as much as it’s for others. If two people interacting are both wearing - even loose fitting - cloth masks over their nose and mouth, the chance of spreading disease is orders of magnitude less.

  We do not actually know that. That is the point.

    We actually DO know that

      Well, then where is the scientific evidence that simple masks reduce chance of spread by an order of magnitude, as described? There is none, because the science hasn't been done. There's a viral JPEG on the internet that claims this, it's just that. If we don't have that evidence, the we don't really know, plain and simple. That's not to say people should stop wearing masks. It's plausible that they help. It's just that we don't know the extent to which they help.

      That's a projection based on assumptions on the efficacy of masks. The point is that we don't have a number for that efficacy. We just don't know.

    People are talking elsewhere in the thread about glasses fogging up. That, even with an extremely non-airtight mask, that is reused, touched constantly, etc. seems like prima facie evidence to me that it deflects the stream of droplet-laden air from your face, thus inhibiting it from spraying on to others. Like others have said, if this were a different disease, maybe it would be spread more by contact and masks wouldn't be worth bothering. And if you're only focused on how a mask can protect you, maybe it doesn't help that much. But if you are infected without knowing it... Edit: my pun was unintentional...really, I swear.

    But we literally do. Do a cursory google search. Hell even Pence wears one.
