I've read repeatedly (and heard on the radio several times) that wearing a mask if YOU are infected will help protect other people, but if you are not infected then it has no known protective effect ie. is not thought to be any more protective than not wearing one.
Do you have any evidence to back up you talk of masks?
(And if YOU are infected you should not be out anyway)
Edit: I was thinking of non-medical situations. @j7ake below, clearly pointed out they work in medical situations, something I was not contesting at all but did not make clear. The original post talked of "wearing masks in public" which was clearly not in medical situations and I was following through that.
