Yes that's right. As the signs at my workplace say: "My mask protects you, your mask protects me." The point of cloth or disposable surgical masks has never been to protect the wearer, but to diminish the chance the wearer will spread the virus. The same way the point of a surgeon wearing a mask is not to protect the surgeon, but to protect the patient from the surgeon.
Ahh. Must be some of that magical, mystical quantum spookiness Einstein was so concerned with.
So, these masks, these quantum masks, they can stop a virus from being expelled through them, despite the fact that the cause of the expulsive force is pressed up against the mask, but once that virus gets past the first mask, every other mask in the room suddenly becomes powerless to stop that self-same virus from penetrating the mucous membranes of every other person ... in the room, in the region, in the world?
Wow. Quantum masks. Who knew?
On another subject, there's an interesting little device stuck on the end of all my faucets at home. It quite resembles a woven cloth mesh. The openings in the mesh are quite small, but still substantially larger than water molecules. And interestingly enough, while it does create some measure of back pressure on the plumbing system, it effectively takes large globules of water and breaks them up into smaller globules. Of course any small particulate matter contained in the water stream, like dissolved minerals that discolor the water, have no trouble passing through the diffuser.
Something else I've noticed (by accident): I installed one of these new-fangled twisty, snaky faucets that can be pointed in many directions, and the water spray goes much, much further with the diffuser attached than it does without the diffuser.
So, it seems to me that, other than catching a few gross droplets here and there, these cloth masks - as opposed to a properly fitted, properly exchanged, N95 mask - merely act like diffusers on a water faucet, effectively aerosolizing large droplets into smaller droplets and ensuring that they get spread farther, and wider, than would otherwise be the case if the person in question was going face-free.
But, that's just my two cents' worth.
