Media is now picking up on the senior @WHO advisor whose comment was NOT to provide N95 masks because they might lead to acne.

abc.net.au/radio/programs…

#COVIDisAirborne

Side note: his comment about decreased O2 is garbage. 3% diff, small N, and the ppl had no subjective effect
I have noted he has put this in print before.

The intro suggests the harms are severe, but pulling the _citations_, which I should not have to spend my time doing, revealed that they were about acne.

He also wrote this piece on behalf of the @WHO, which was meant to support droplets, but actually proved ventilation was great because they didn't check their citations well enough.

An unpublished email was used as a source, but not cited. Instead, a review citing the email was cited

This makes it difficult to discern that the data is coming from a personal communication. This does not meet style guide requirements for that reason

The thread on the ARTICLE about acne (3 posts up) may be broken for some people.

The continuation, with the citations, etc., is here:

Here, the ENTIRE thread together:

threadreaderapp.com/thread/1316381…
As for oxygen, he says small decrease his OWN study said no subjective effects at all (ppl did not notice).

Quick search and found ncbi.nlm.nih.gov/pmc/articles/P…

No effect of N95 masks. 1 hr slow walking = nothing. 4 hours = slight increase in respiratory effort prob the moisture. Image
When a view doesn't accord with actual science, the arguments become more specious and desperate. I leave to readers to decide if we hit that point.

It would be noteworthy and that's it, if it weren't deadly. No mask _will_ statistically lead to death.
No mask, or surgical vs N95. I treat them the same because surgical masks are not designed to stop aerosols. Period.

The arg against is technical, to say this study or that study is not proof ENOUGH that they work.

But since surgical never meant for aerosols, we are done here
Interesting side note:

Copernicus discovered that the Earth revolved around the Sun.

This upset lots of established people. They really wanted the Earth at the centre. They attacked Copernicus' ideas.

Want some fun?
Tolosani attacked Copernicus and his ideas.

What did he say?

** You have not sufficiently PROVEN your theory. **

Does this sound familiar?

What do I keep saying about humans repeating repeating repeating everything? ImageImage
The nice thing is that when you have looked at the totality of the evidence and you see that these things all spread in small aerosols and infection is statistics, you can just sit back and wait. You know the sea change is coming.

You'll be right.

It's just a matter of time. Image
Mask up people. Avoid indoors. Be safe.

#COVIDisAirborne

(psst, we'll solve acne after we get through this pesky viral pandemic.)
*Avoid if can, of course.

Minimize ppl and ventilate regardless.

Be safe.

Just one more study in a long line ...

Did you know we've been killing ferrets since 1945 to show viruses travel in the air?

And then others complain they're ferrets not humans, missing the forest.

(Different strains in animals may yes be more transmissible. They mght bind less well to the recipient cell receptor. Or bind only to a receptor deeper in the lung. But this is observing how well, not how, they transmit.)
Poor ferrets Image

Okay, apparently acne is trivial. I agree. It seemed a trivial thing to say.

So, let's focus on the impartial, unbiased science, right?

Because everybody's interested in truth, right?

Okay, let's go!

Uh oh, we know what that means.
A slide mentioned _no cultured SARS-CoV-2_.

It contained citations. Image
1. It quoted Santarpia, as a pre-print.

Unfortunately, Santarpia was later published in Nature. (nature.com/articles/s4159…)

And by the time it was published, Santarpia had cultured live SARS-CoV-2. See pic.

So.

Are we done? Image

CORONAVIRUSES WERE NEVER DROPLET ONLY (an droplet is a meaningless term and should be redefined as "airborne but not that infectious")

FROM A 2016 TEXTBOOK. YOU KNOW, A BIG BOOK OF KNOWLEDGE Image
AND ASYMPTOMATIC CASES OF SARS.

C'MON people. Enough with just repeating talking points. Image

Outbreak at Quebec gym now up to 171 people (not all at gym I am guessing) per CBC News At Six last night.

So that plexiglas and 6 feet did ... as everyone who knows aerosols said.

Filter the air. Ventilate. 6 feet not magic.
Anyone know any gyms that focussed on ventilation? Could see how they've done.
Anecdotal story of gym w ventilation in thread.

Yes cannot draw hard conclusions from one or two instances. This is in addition to all the other evidence. Also superspreading is random.

New variants more transmissible now, caution.

Still, this lesson repeats again and again

"... because #COVIDisAirborne."

Fixed it.

Psst, in actual fact, @WHO's committee on COVID-19 transmission modes is logjammed by some of its members. They refuse to admit SARS-CoV-2 is in the air.

So @WHO has to quote any old doc mentioning "air" to get around its own committee
That's why the committee in July 2020 said they were "actively discussing" whether SARS-CoV-2 transmits in aerosols

(see pic, from who.int/news-room/comm…)

Not very actively, apparently, since it's April 2021 now and no change.
The clear statement that SARS-CoV-2 transmits via droplets (that fall to ground) is found also in @WHO's mask guidance from June 2020 @ apps.who.int/iris/handle/10….

If only medical doctors can be called doctor in the media, then I demand we go back to calling surgeons "mister".
Backstory, see pic.

Apparently if it's anything like droplet theory, we should keep doing it for another hundred years.
