An Official Conference CoVid Mask Rater Thread: #2022ASA

These folks get a 9.5/10. Period.
A presenter in a respirator? What?!
More folks in respirators?! What!? So confused...The Public Health conferences never looked like this!?
@AmerStudiesAssn is swinging for the fences!

Respirators only, please!

Receptions outdoors? Can one fall in love with a conference? Pitter patter.

No one but us transmission prevention specialists know that transmission can still happen outdoors. But. Super-spreading is bloody well much less likely to happen.

So kudos.
Testing with 24 hours of conference start?
Rapid testing? Every day?!
"Have the bivalent boosters - or you are dead to us.".
A personal attestation....love to see it!

Would have loved to see #corsirosenthalboxes or HEPAs involved. Headband N95s instead of KN95s (60-70% fake on Amazon), as those earloops slowly ease forward.

And of course, having virtual - but they went out of their way to talk about that...this entire clip is about it.
So, not perfection, but you can tell they are trying, and have done a fine job.

And that's 1000% better than some of the others we've seen.

Over a year's worth of conferences:

"COVID IS OVER, YOU DON'T NEED THAT!"

Reason 4,657 on why I mask now that I understand aerosols and transmission. It's not all about COVID.

This is Chicago, but it's really Anytown, USA. Image

EV-D68. An enterovirus - many people think enteroviruses are strictly fecal-oral.

They think wrong ( this is not a subtweet at Dr. Johnson).

How do we know TB is airborne?

71 guinea pigs gave their lives between 1956 and 1958 in the eponymous study by Riley et al, getting TB air piped in from some TB patients, to prove TB is airborne.

Influenza is kind of airborne per most doctors. But kind of not.

So....

We need some volunteers.

Will horses be those volunteers that finally lay it all out?

Yes - but none of them lost their lives.

Air samplers were deployed and tracked horses inoculated with Equine influenza virus (EIV).

From the very first day post inoculation (dpi), until the Image
12th day, EIV was found in the air, in this new study.

With no horses, or guinea pigs, hurt in the process.



But sure, influenza's not airborne - if you are the USDA, right, @nirav_maine?

Of course, yet another new study points an accusatorysciencedirect.com/science/articl…

Thank you @BarryHunt008 for flagging this.

@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.

Lol.

They are just apparent supplement grifters.

I noticed they were using @NukitToBeSure's excellent torches as their example picture.

Strange to be so selective of an example picture for someone purporting to be an independent news source on health.

Hmm. I helped defend Nukit against charges of Image
racism by a very nasty couple who it turned out just do not like UVC, personally. I wonder....

Yep, ThailandMedicalX has blocked me.

But, it's weird for a purported news source to block someone like me @gorskon
@doritmi @19joho.

And them blocking me, is probably because Image

You've heard of "The Three Problem." - great book, and excellent Netflix series.

If you want to be avoid catching Covid, you probably have "The Empty Room" situation in the back of your mind.

How long after a room had people in it, can you safely demask?

Measles was thought to be airborne after a child caught measles an hour after the infected child left the same office.

.

Interestingly, you can see the reluctance in blue below to call measles airborne. Much like the WHO with @mvankerkhove researchgate.net/publication/19…In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The...
which spent millions to rebrand SARS2 as "through the air" rather than airborne.

It is an inconvenient truth that then leads us to the study showing an #EmptyRoom SARS2 infection at 1 hour and 43 minutes, and FOUR HOURS and FORTY-FIVE MINUTES.

In this study, it comes with Experimental evidence suggests that SARS-CoV-2 remains viable within aerosols with a half-life of approximately 1-3 hours, though changes in aerosol microenvironment may shorten viability to minutes. However, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing of nasopharyngeal samples obtained from patients on an outbreak unit suggested in-room transmission of the delta variant, AY3 lineage, of SARS-CoV-2 to two patients admitted 1 hour, 43 minutes and 4 hours, 45 minutes after discharge of an asymptomatic infected patient. These findings suggest...

Mum's the word - if @SecKennedy is Mum.

You see, I have been a VERY FOCAL CDC critic. But you can't criticize without listening.

And I have been noticing that that the CDC has been very, very quiet.

NPR noticed as well. Image
This is crazy. Image
Yes, the @CDCgov has been deathly quiet.

90 times last year, versus 4 this year.

This is not MAHA.

This is MASA - Make America Silent Again.

And as one of the CDC's most focal critics? We NEED them to be sharing Public Health information. Image

Fit factor of 250- 4000 versus the normal 100-200 for an N95? Where do I sign up?

Oops, that's here. With me. Starting a build with an Ebay'd Bullard EVA PAPR's filter - and some DIY loving goodness of a heat gun and PVC pipes.

The benefit of this build will be the over 10
hour run-time of the massive battery on the PAPR.
Got a long dental appointment? This will be the answer.

Let's get cracking!
