there isnt much training required. I worked in a BSL 3 lab with aerosolized tuberculosis and the training was like 5 minutes.

Even if you touch the mask with your hands and it is contaminated, if you wash your hands after taking the mask off you will be fine.

The "you need training" is part of the media agenda.

I agree that statistically masks wont stop the virus from spreading in the public. While masks used by health care workers will stop the virus from spreading to health care workers. The reason is that most of the public wont use masks while all health care workers will.

I could have left out the training part of my comment because it's not important to my argument (although my guess is that you'd be very surprised how many people who wear these masks in public use them extremely cavalierly and improperly).

The rest of my argument stands if you drop the part about training.
