Anyone: how true is it that COVID-19 is NOT airborne?
Good question. I am off to Google more about that.
I’ve heard doctors say it IS airborne.
Since he was in “hot spots” I’ll take his word for over some egg head on TV.
Some reports are that it is active airborne for 3 to 4 hours, and on hard curved plastic and metal surfaces for 3 -4 days.
This implies any large facility, mandated by the Democratic Socialists to conserve energy by recirculating air conditioned or heated spaces, is that in any large bldg, anybody who is not exhibiting symptoms, but is still infected with COVID-19, can now sread it to anybody else in the same bldg if the air is recirculated within 3 hours.
Next, if the HVAC manager is saavy enough to quadruple his energy costs, by using all Outside Air, he must also exhaust the contaminated air, so flues now must be installed on HVAC Exhausts to insure exhausted air never reaches the Outside Air Inlets within 3 hrs of exhaust.
Likewise, exhausted air must not be able to venture into adjacent bldgs and their HVAC systems.
Meanwhile, all door locksets would need to be replaced with push bars and until such time, always carry a disposable hand towel to wipe of surfaces before touching them, such as elevator push buttons, handrails, door knobs, pull handles, valve handles, hand dryer buttons, etc.
It will be another AIDS warning behavior to use your foot to open everything.
Not airborne - carries in droplets from coughs/sneezes and drops put of “circulation” fairly quick....if it was airborne, we’d have a billion cases by now.
Covid19 lasts:
About a day on cardboard
Lasts 2-3 days on steel and plastic (13,16 hour half lives respectively)
lasts only 4 hours on copper
lasts 3 hours floating around in air (tested at room temp and 40% humidity)
Lasts longer in cold air and dry air.
Other papers show that half life drops dramatically in air with higher absolute (not relative) humidity. So Florida might have slower spread?
Nosocomial (I had to look it up) refers to an infection acquired in a hospital or other health care facility.
