Sweden’s disease expert says just wearing face masks could be ‘very dangerous’

“Thus the popularity of the masks with valves that don’t filter exhaled air.”

You mean full medical PPE? A full setup will go a long way toward not catching the virus - otherwise medical personnel would be dropping like flies - it’s function is to protect the wearer, not so much as to stop the wearer from spreading.

If we all went about out daily lives decked out in hazmat-like threads the infection rate would doubtless go down to almost zero. But you’d have a hard time getting everyone to go along with that!

[Karl Spooner]

Yup, masks help spread the disease. That’s why they want you to wear them.

A mask may indeed catch some moisture laden with COVID, but that which escapes likely is forced out through the mesh at a far higher velocity, thus traveling farther.

Compare a water hose to a water hose w/ nosel.

Who knows anything.....it’s all ridiculous.

[heartwood]

Misleading headline. Mask wearing mot dangerous in itself, only if it leads to other risky behavior.

[PIF]

Do the test your self ... put your mask on, get a vap pen, inhale the smoke particles (3 microns, same as virus) and then exhale through the mask. You will find that smoke comes out of the mask everywhere. Most masks will behave similarly. the only type which is different is the rubber kind with goggles and interchangeable filters; smoke will not penetrate but exhausts at bottom.

It is very important to emphasize that the virus aerosol particles are 3 microns in size. This is very small and there are few, if any, masks that protect you or the other guy against particles that small - short of a bubble suite with it own oxygen supply.

Last kind protects you but not the other guy - all others protect no one and are only good to remind you not to touch your face.

Then there is this problem

And this

There are N99 masks which are expensive (like $20 each) and usually single use of limited duration which have dual valves - in and out. However, the out valve does not protect the other guy from you.

until a reasonably-effective vaccine is widely distributed for that to work.

[Verginius Rufus]

There was a cartoon a few days ago with a woman wearing a mask talking to a man who was building a chain-link fence—to keep mosquitoes out of his yard.

That’s the problem with most solutions; until it’s out there in the real world you don’t know how well it’ll work. All you have are test runs.
