Update 6-14-2020: 3 paragraphs in original article highlighted, and two more appended below as part of this update, which addresses the recent spike-up in cases as we re-open.
--------------------
When there is a new disease,
for which there are no treatments (other than support) and no
preventatives (such as vaccines), there
is only quarantining, at one level or
another, available to use as a tool to
stop the spread of the disease. This
tool is centuries old, but it
works, and combined with modern
knowledge of the microbe theory of disease,
it can be rather effective.
That’s the result of the accumulation of factual knowledge
through science. There are no
“alternative facts”, there are only
lies. It is now, and it always has been, best to use what we know to be true. And there is no better way to know
what is true than science!
When this SARS-CoV-2 (“Covid-19”) pandemic started, we knew next-to-nothing about its
characteristics. Very quickly, we learned that it is transmitted from person
to person by virus particles contained in the tiny respiratory droplets we
expel when we breathe, talk, cough,
or sneeze. The virus particles
cannot live in the air outside those droplets.
These droplets tend to fall to ground fairly rapidly, and they can persist on surfaces where they
fall, or are otherwise deposited.
That it spreads in droplets means that face masks are
moderately effective in stopping disease transmission, as the size of these droplets is large enough
to be stopped by filter media through which we humans can still breathe. That would include both paper and cloth
masks, even simple bandanas. The physics of this says that in most
situations, the mask does not protect
the wearer, but it does protect others
from any disease the wearer might have.
Only when up close, really
“in-your-face”, does the mask
significantly act to protect its wearer (such as medical workers).
That these droplets tend to rapidly fall to the ground is
the origin of the 6-foot rule (or in other metric parts of the world the
2-meter rule) for physical distance between folks. If you get closer, that’s rapidly becomes the “in-your-face” situation. Like the face mask, this distancing is also moderately effective
at stopping disease transmission.
Now, acting
together, masks and the 6-foot rule
are far more effective at preventing disease transmission than either is
alone. That’s why the CDC
recommendations say do both. It’s an
“and” situation, not an “either-or”
situation. And it is not supposed to be
optional: when I go to the grocery
store, I see too many shoppers not
wearing masks, and getting too close to
each other. Shame!
There is a third thing that can be done, also moderately effective by itself. That is wearing disposable gloves when
handling items in public that are touched by many. If you add that to the masks and the 6-foot
rule, there is little risk of
transmission of disease, such as when
you go to vote. This would be true even if the crowds were large, and the voting machines were not disinfected
between voters (which they should be).
You will note in some news stories that workers in some businesses are
using these three tools together. Now
you know why.
What we have learned over the last couple of months is that
this SARS-CoV-2 / Covid-19 disease is more infectious than most ordinary
influenzas, and (more alarmingly) that a
large fraction of infected people show no symptoms. They do not know they are sick with it. And for a couple of weeks while they have
it, they are spreading it like “Typhoid
Mary”. Not feeling ill is NO INDICATION
you are not infected and infectious!
Again, that’s just a scientific
fact. Doesn’t matter how you feel about
it, it simply “is”.
When this started, we
didn’t know so much. It was wise to
close down all gathering places of any kind where disease might be spread from
person to person, same as in centuries
past.
Now that we know as much as we do, there is no reason these businesses and
activities cannot resume, as long as
the transmission of disease is interrupted!
The main tools are face masks and the 6-foot rule, augmented by gloves and face shields and
frequent disinfection, as
necessary. Every such activity is
different.
And it is morally incumbent on the operators of any
activity to look closely at what is done,
by whom, and how exactly it is
done, to determine how best to use these
tools to stop disease transmission.
There are a few activities which cannot comply. For public safety, these must remain closed.
The ideology-based objections to these quarantining tools
and the activity shutdowns have no basis in our law or our society’s
history, dating back to before the
founding of the Republic. Public health
has always taken precedence, even in
George Washington’s revolutionary army.
There is a longstanding legal tradition that my right to
swing my fist ends before I strike you with it. Likewise,
your right to behave as you wish ends before you infect me by
your behavior. So, wear the damned mask! Stay 6 feet away! Don’t open your business until and unless you
can stop disease transmission in it.
Simple as that!
It could be a lot worse.
There are diseases (like chickenpox and measles) which can exist as bare
virus particles floating around in the air.
No mask you could breathe through, could ever stop them, not by a long shot (science again). Walk into any confined space where such
are, and you will be infected! If this pandemic were one of those, we could not safely reopen anything.
It is not. So, count your blessings, do this right, and let’s get on with the war.
And quit bitching about how public health orders violate
your rights. They don’t. Your rights are NOT absolute. They never have been.

Update
6-14-2020:
It’s
official, Covid-19 cases are on a sharp
rise after re-opening, even here in
Texas. Not enough people are taking the
mask and 6-foot rules seriously. Not
enough reopened businesses have taken seriously giving their operations a hard
look for how to prevent disease transmission.
This is exactly what the medical experts warned us would happen.
To
those who have not complied: either you
take this seriously, or we will have to
shut down and stay at home again. If you
take preventing disease transmission seriously,
then you don’t have to shut down or stay at home. It’s your choices that make people sick and
dead, or not.
Update 7-14-2020: Well, we opened up too quickly, and with too many people behaving like there is no disease problem. There is no reason why businesses and other things cannot be open, as long as careful attention is paid to stopping disease transmission. But too many people are either too stupid to understand the science, or too incapable of critical thinking not to be deceived by internet lies and conspiracy theories. The worst of which keep coming from our president and his ardent supporters, instead of actual leadership in a crisis. November is coming ---

It has been found that rioting is 100% effective at preventing the spread.
