--- Quote from: imo on March 24, 2020, 08:30:41 pm ---I've never ever heard or seen somebody saying those general public face masks can protect you against the virus. In opposite, all say "be aware the simple mask do not protect against the virus".  All what CDC or WHO says is true, absolutely. The argument "you need trained medical personnel who can handle masks properly" is perfectly valid for laboratory and medical environment where the personnel is exposed to bacterial or viral infection.

The general public masks (ie DIY) protect the environment around the Wearer from droplets he/she is spreading by coughing and sneezing and talking. Those are his/her droplets with his/her viruses caught by the mask he/she is wearing. That has been explicitly said here many times, afaik.

An infected person tugging at a virus soaked mask sounds like a great idea.

An infected person who is not safely at home is a problem no matter what they are doing...

For varying values of 'work'. If you wear a mask incorrectly, does it do anything at all? I would suggest it has some effect - it won't be the 'proper' working fully protective effect, but it would surely be better than nothing at all, wouldn't it?

Kind of like if you wear a crash helmet incorrectly it's not going to be as effective as if you did it up properly, but there's a non-zero possibility that it will lessen a bash on your bonce all the same. [OK, not quite analogous because an incorrectly worn helmet might kill you whereas a mask won't, but let's not go down that kind of rabbit hole.]

Look for X-Ray pictures of people who had their feet on the dashboard of a car while the airbag exploded. Now think again about safety features used the wrong way. Just follow the advice from the experts.

In what circumstances would a mask not prevent or significantly reduce "spitting" from someone talking or sneezing?
