Maybe you can find a video from last year or earlier with a HCW wearing one, but no more. While it is more likely the patient has more viral load than the provider, we can not be certain any HCW is NOT spreading the virus.

Not sure how this matters for "Coronavirus and Travel", the subject of this board, because no HCW on a flight needs the same protection that they need at work, and the cabin is not an ICU.
