That is true. I realised that after I sent the message. In a way we are all

I believe you are wrong about that. Surgical masks are worn to protect the
patients as much as the doctors.

When you think about it, I don`t think masks have ever been designed
explicitly to keep stuff in.
As far as I know masks have traditionally been designed to keep stuff out.
Keeping stuff in is a new concept.

[Vo]:Useful information on masks

2020-08-09 Thread Jed Rothwell
This is off-topic, but important.

It turns out that cheap, throw-away "surgical mask, 3-layer" type masks
work best. These are the ones you can buy anywhere nowadays. Office Depot
sells them cheap.

See this research article in Science:

Knitted and bandana types are not recommended.
