DYK that you, and me, and everybody are Pig Pen from Charlie Brown?
We shed our entire outer layer of skin every 2-4 weeks, about 500 million cells daily.
Your corneocytes (outermost cells) lift off of your body with the
gentlest of micro-air currents. Like a leaf picked up off the ground for the briefest of moments in fall.
They act like 12 micron aerosols in float time, but 25% of total skin flakes are sub 5 microns...and you know what that means. Deep deposition - or shallow as
sub 5 likes to also deposit in the nose.
It's funny...I embrace push-back in debate. Tightens up my game.
Imagine if those skin flakes now have Ebola on them?
Two studies show that Ebola literally oozes through the skin - both ways. In and out.
"...due to the desirability of an off-
the-face design, and not for protection from aerosols, respirators may be used instead of medical masks"who.int/publications/i…
If you can stay 3 feet away while screening? No medical mask needed.
PCDH1 (protocadherin-1) is primarily expressed in the airway epithelium of the respiratory system, especially in the bronchial and nasal epithelial cells, and in pulmonary endothelial cells.
