Apparently, none of the "infectious" diseases have ever been proven to transfer from one person to another.
I am open to any difference of opinion.

I found this Comment paper to be very informative and unsurprising. Following back the mountain of information given to the public (to which I belong), (including Dr. Fauci's & others' intentionally misleading, but well-intended, mask-wearing guidance and reasoning), I recall that very early in the onset of the stay-at-home directive, the medical community, incl Dr. Fauci, were explaining & demonstrating graphically how long in suspension certain-sized aerosolized droplets/particles remained from an infected person having been in, but no longer present in a room. It was communicated clearly that virally-contaminated particles (droplets, areosols, whatever they may be called under specific conditions) remained suspended for a period of time.

Also showed was an example of how far a person's cough or sneeze traveled with and without a mask, including the air excape from the poorly-sealed non-N95 masks people are wearing, which validated the 6' recommended social distance. They also spoke about the settling of these droplets on surfaces and how long they remained infectious on various substrates (hence the sanitizing of foods & products, until it was decided that it didn't hold as much of a risk as earlier thought).

When people quarantined at home where others resided, they sealed the vents and put towels under doors to minimize as much as possible air flow between rooms.

From my memory of these early explanations, demonstrations, & guidelines, I'd say the CDC & NIAID knew it was aerosolized AND dropletized, since the difference between them comes down to the droplet size that the virus is carried on & its relationship to viral load. It also appears that in the preparation of information for public consumption, the selectivity of the information (including guidelines), the context given it, and how it's been presented at any given time, has gotten a bit tangled under their feet at times (again, the mask & type of mask-wearing's a good example).

In my opinion, the CDC, NIAID & other experts leading the country and the world through this nightmare have done a superlative job. Mistakes or what turned out to be errors in judgment in what and how information was given have been minor in view of the whole. If not for Trump, I strongly believe a significant number of deaths would have been avoided. The medical teams did their jobs.

When studying it in retrospect, there will be a lot to learn about communicating with the public to achieve trust and a partnership in ensuring the best outcome for everyone. Straight and direct garners greater & more durable trust & confidence than molding & shaping, because there are enough smart & savvy people to see through it & sound the alarm that something doesn't add up (again, the masks; Fauci's rationale made no sense to me, tho I knew why he did it; still, a loss in trust & a watching-out for other half-truths). I believe it is better to cater to the intelligence of people, rather than to the ignorance of.

It should make for many very interesting and challenging meetings, confedences, and educational courses, when considering the catastrophic (& hopefully unique) circumstance of two completely different publics!

Anecdotal supposition is not enough to support this claim. It is surprising that aerosol sampling techniques have failed to produce evidence of viable SARS-CoV-2 particles for culture.
Thus we must continue to assume that methods of transmission include aerosol, large droplet and fomites.


John Welden

In other words, at the start of 2020, “decades of research” demonstrated covid transmission was most likely airborne, but public officials ignored this and for some as yet unexplained reason adopted a health policy from 1918.
