Good point!
> If someone sneezes at you, even most simple mask will stop at least 50% of viruses
sounds plausible, but any reference for that figure?
FFP2 / N95 respirators - 90-something percent, medical "blue" masks - 80 percent, home-made piece-of-cloth style ~ 50%.
Wearing sunglasses is encouraged too. Both to stop the load if someone sneezes at you and discourage from touching your eyes.
Medical mask - 96,4%.
Home made mask - 60-96% (depends on cloth and sewing).

The main problem with blue masks and home made is that they tend to get wet from breath and their effectiveness go down the drain.
