[ARC5] AB5S Kung Flu Update, 13 June - source?

[Scott Johnson]

I consider the primary reason for masks, or bandanas, or whatever, not to
protect yourself, but to protect other from you.  It is a courtesy, if you
sneeze, cough, or slobber when you talk, it effectively prevents the aerosol
from going further than the fabric.  Not wearing anything in proximity to
the public identifies one as  careless and reckless.  If you are in a high
risk group, and truly worried about your own safety, then you shouldn't be
exposing yourself needlessly.  I have heard so many opinions, some that are
diametrically opposed, and all from supposed experts.  Don't care to hear
any more. Common sense coupled with common decency should prevail.  BTW, one
of my engineers did a CFD model in Solidworks of a sneeze in a room with
closed loop HVAC.  It propogates and dissipates pretty much like a fart.

Generally good advice, but I question the non-cough non-sneeze 26 foot
business, no matter what your doctor said.
I have read several articles in the New York Times precisely on this
question, and those articles are well informed, very well informed,
frequently updated. Ask your doctor his source for his information. I recall
now they also had an article comparing actual effectiveness of different
kinds of masks, both homemade and commercial, and gave actual numbers
compared to N95, and what thickness required even with homemade.
Also, masks are dry material, so what is your informed reckoning of how long
virus lives on them ? 
As for health professionals dying despite masks, well, you would have to
know the extent of their exposure and their full suiting equipment to assign
this to mask inefficiency.
Don't forget UV exposure either, to kill virus. These parameters apply
outside also. 
I found Elderberry anything to be pretty much sold out locally last time I
shopped, but I'll take another look in the next days.
