Off the top of my head, 30% risk reduction if the uninfected person is wearing a mask, 70% reduction if the infected person is wearing a mask, 95%+ reduction if BOTH are wearing a mask. So while it's most important for infected people to be wearing one, it's optimal for both parties to be wearing one, and has SOME protective factor if just the healthy person is wearing one. These studies were carried out quite quickly and extensively in the US because they are desperate for an alternative to closing businesses, so the data has only become available since they started getting many more cases.

That is true however the WHO changed the advice several weeks ago and the UK has been dragging their heels deciding on whether or not to implement it being mandatory. This isn't a Scottish brag either - it was only made mandatory here at the end of last week. It's been mandatory in other European countries for much longer.
