Suddenly I have seen a couple of companies advertise plastic shields as an alternative to wearing masks on tv. They are NOT a replacement for masks, they are a reinforcement. The direct contact of a mouth nose mask is the first and best line of defense.
The plastic shields are intended for surgery and possible splatter, not air born contagions. They are certainly excellent back up for a mask, but they are NOT a replacement.
Laypeople who buy this dangerous marketing, don't understand it isn't about sneezing or coughing or even feeling sick. A virus can float in the air unseen, and it can go through air conditioning/heating systems and circulate in any direction, up or down depending on air flow in the building you are in. And it isn't just about airflow, it is also about touching things and transferring by touching other surfaces that others touch.
There is ultimately no replacement outside a vaccine for a mouth nose contact mask.
And not even a mask it all there is to it.
It is a combo of things.
Washing your hands frequently.
Cleaning all surfaces constantly.
WEARING A MASK
Keeping your distance from others.
And every time I see these new ads, all I can think is has the FDA or AMA approved the use as advertised?
