So could this be more about sizes of droplets containing virus particles? That is the heavier droplets will fall because of their weight but the lighter droplets or aerosols remain suspended in the air longer and can be carried longer distance by the HVAC.

Or they just build up and you get a cloud of aerosols. Even though they carry much less virus load per aerosol than large droplets, collectively they may pose a transmission factor if enough of them build up and form a cloud in indoor spaces where people spend a long time, such as bars, night clubs, restaurants, etc.

It would be more alarming if there would be documented cases of aerosols causing infection outside. But there's no easy way to differentiate between whether people were infected by droplets or aerosols or maybe even fomites.

I omitted it because it doesn't save the bad data.

TTT

If it was truly airborne, wouldn't we have more cases of infection in healthcare settings? I know many clinics and hospitals aren't using airborne precautions for covid patients unless undergoing specific procedures. If it was hanging in the air of clinic exam rooms and hospital hallways, wouldn't there be more infection in healthcare workers and other patients?

WWWNCDC is the Emerging Infectious Disease journal made to help scholars in Asia get publications under the "CDC" name.
it is not CDC work.

And much of that work has had a very low threshold for publication and suffer from lack of peer review. So take anything from that journal with a grain of salt.

As for the elevator paper, it is a nice story, but just like the one where they plotted the tables in the restaurant with the air conditioning direction, but never tested the waitstaff, it is meh.
Remember the one that plotted the people on the same bus who all caught COVID? that one was retracted.
Also, the genetic clades seen in China are pretty tight with little variation, so not sure if it proof it came from a single source.

As a follow up to this story, in the WSJ today (Behind a pay wall)

Red flags raised over Chinese Research Published in Global Journals

"Internationally peer-reviewed journals published more than 100 scientific research papers from China-based authors that appear to have reused identical sets of images, raising questions about the proliferation of problematic science as institutions fast-track research during the coronavirus pandemic."

There is also a similar article in Forbes published last month

An interesting BBC report from Wuhan, with interesting graphics on the functioning of Sars-CoV-2 - quite enlightening for the layman like me.

Interesting indeed. So many unanswered questions still.

And finally Common Cold Coronavirus T-cell priming makes it into the mainstream.
Joe is a character, but he does have a masters from MIT in molecular biology, so...

"It doesn't seem that high" possibly because we are not looking for it enough yet in the quest for a proprietary and profitable vaccine.

I didn't see that segment but apparently NovaVax got like a $1.5 billion grant, the biggest among Project Warp Speed vaccine candidates.

Their vaccine supposedly will try to stimulate a T-cell response but the CEO admits he's not sure the vaccine will work.

Although @FlitBen had already mentioned the Henry Ford study on HCQ, thought that everyone interested should be able to read the actual paper that has been published.

"Treatment with Hydroxychloroquine, Azithromycin, and Combination in Patients Hospitalized with Covid-19"

It is an observational study with the following findings

• According to a protocol-based treatment algorithm, among hospitalized patients, use of hydroxychloroquine alone and in combination with azithromycin was associated with a significant reduction in-hospital mortality compared to not receiving hydroxychloroquine.
• Findings of this observational study provide crucial data on experience with hydroxychloroquine therapy, providing necessary interim guidance for COVID-19 therapeutic practice.

What I found interesting was that none of the national media such as Wapo, NYT, USA Today, AP covered the story (at least with any fanfare).

Who wants to claim that their vaccine will work when they don't know if it will

This is a public company. You can get into big trouble with the SEC making false forward claiming statements

How is this observational study any different from what Didier Raoult did in Marseille, when he was the first one to promote HCQ?

I saw another observational study by a doctor trying to promote Famotidine and Zyrtec as a "double antihistamine" therapy for C19. He's actually trying to patent the idea.

They obviously didn't have a control arm so he published his findings vs. the observed data from other sources for how people who didn't take these two antihistamines fared.

The Oxford developers have expressed confidence, based on their previous work with other coronaviruses.

The Moderna people especially the CEO are known to be huge self-promoters.

This NovaVax CEO's comment was notable because it was in contrast to what the others connected to other vaccine efforts have said publicly. That and the fact that his company is getting $1.5 billion from the govt.

Researchers from Univ. of Arizona and Univ. of South Florida have tested and identified 4 protease-inhibitors which have shown antiviral activity against the virus in the lab.

Interesting is that they reference some other antivirals which did not work as well, such as some AIDS drugs, camostat and others.
