Putin May Have a Point.

When I see a person in the street wearing any sort of mask.

I just see an invitation to punch.

Likewise if I were a frontline healthcare worker. Being told by a manager to wear the same respirator all day.

I would tell that manager to go forth and procreate.

In not so many words.

I would rather risk going without respirator. Rather than carrying a virus reservoir on my face all day.

For frontline healthcare workers though it is a serious risk.

They will be hit with a viral load that not even the sickest patient could imagine. Let alone some idiot on the street.

For unconscious patients in ventilator beds gas masks may well be a viable alternative. Ideally of the fullface/visor type

You keep the mask on and just switch the filter cartridges out.

I suspect most militaries have decent stockpiles of the right sort of filter.

Much of which is probably going out of date. This long after 9/11.
