H/ T @healthyheating for a VERY cool study!

Robot babies, Covid, and resuspended aerosols!!

Hang onto your nappies, kiddos - it's a good old Tweetorial 🧵 with a pay to play study. So, free!

TLDR? Vacuum your carpets, and run the most air cleaning filtration you can afford Image
"We are perpetually surrounded by a cloud of self-induced resuspended particles, referred to as the".... Pigpen effect (my thread, my word, Pigpen).

It is on the order of smoking in terms of particulate rates emitted. twitter.com/i/web/status/1…
Infants can travel up to 20 football fields during a day, with a path as crazy as a cat zigzagging through a room full of Roombas.

If we can kick up our own dust, you would think infants could. And that's what they set out to measure. twitter.com/i/web/status/1…
That dust cloud is a mix of chemical and biological stuff. Like living and dead microorganisms such as bacteria. Biological excretions like animal and mite allergens.

And PFAs, phthalate plasticizers, and flame retardant.

And might include toxic metals like lead. twitter.com/i/web/status/1…
So, they put together a robot infant and ran her over 12 carpets methodically.

And when I say methodically, I mean it.

In the Methods section, there is a link

(I made the mistake of starting this thread last night. Chuckie, below, made his appearance in a nightmare.) ImageImage
that Adobe Acrobat is not letting me grab from the PDF. So, here is where you can find it.

Aerosol and airborne nerds will want to.....fascinating! Image
When the baby started crawling, there was a significant increase in airborne particle concentrations, right where it would breathe those particles.

1.5 and 4 μm size particles? Possibly bacteria and fungal spores.

>6 μm - thought to be biological in origin.
Now, a truly interesting nugget?

When we walk, our personal cloud gets mixed pretty quickly into the overall room air.

Nobody puts Baby in a corner - but they sure put her into her own little cloud.

Because her crawling is not enough to mix that little cloud of resuspended ImageImage
particles.

Another interesting nugget - older, cheaper carpets, counter-intuitively, might be better for Baby. Image
Finally, were the particles inhaled?

Absolutely - see below.

If SARS-COV-2 was brought in on your shoes? It could be kicked up by the baby. Of course.... Image
the most likely source for those Covid particles are from us breathing them out, and then settling on the floor.

So, how can we help our floors stay cleaner?

Vacuuming, of course, but also by cleaning the air with HEPAs and #CorsiRosenthalBoxes (👇).
I strongly encourage you to go read the study yourself as it is methodically well-done.

And just a darn good read!

Here it is, free. (Click the blue button, "Open", on the right.)

Thank you very much, Dr. Stone for laying out this 20 hour meeting so very clearly and concisely!

The HICPAC voted to deny HCWs N95s, deny ALL the protection of universal source control, and have HCW illness time to be so short as to be GUARANTEED to bring more LongCovid.

/1
We can see their lies by just looking at just a few seconds of one doctor's testimony.

To wit:
Doctors don't need N95s because the room has a PPE note on it.

But, after asking a few questions, they go get better PPE.

Here it is
Erica Shenoy, MD, PhD, Chief of Infection Control at Mass General Brigham, and a prominent committee voice who has published against masking in healthcare settings, argued that wearing an N95 respirator for initial patient contact was excessive. She told the committee that her practice is to go into a patient's room (without a respirator), ask a few questions, and then determine the level of protection needed. I understand that since I sometimes did the same—but that was long ago, and when I suspected my exposure would be minimal during that brief period.
To me, this is just a massive self-own by Harvard's Dr. Shenoy. She is too intelligent to be stupid, so this must be deliberate obtuseness.

Let's ignore her condescending tone (she was addressing a fellow HCW who knows exactly what the process is), and look at the facts.

Zombie Deers. Chronic Wasting Disease. Misfolded PRIONS in the brain - like Creutzfeldt-Jakob disease in humans.

✅ In 35 states.
✅ Incredibly stable in the environment.
✅ Highly contagious.

They are not sure how it's transmitted.

It's airborne. Can Rudolph infect Santa?

Normally, I do long threads, but busy, today.

So, here is the source for the basics on CWD:

Fascinating educational article about vaccines and the immune system.

And this was an interesting bit -
Bacterial and viral infections predispose to other infections.

Get the flu? You are at greater risk for pneumococcal pneumonia.
/1 Bacterial and viral infections, on the other hand, often predispose children and adults to severe, invasive infections with other pathogens. For example, patients with pneumococcal pneumonia are more likely to have had a recent influenza infection than matched controls.62 Similarly, varicella infection increases susceptibility to group A-hemolytic streptococcal infections such as necrotizing fasciitis, toxic shock syndrome, and bacteremia.63
Those 👇 post influenza infection effects look familiar.

Where have I seen those types of symptoms before?

COV_D. Which we are getting every year, unlike the flu which is every 5-6 years.

Anywho.....

wellesu.com/10.1086/313772The theoretical bases for susceptibility to bacterial pneumonia following influenza infection are plentiful and include decreases in the function of polymorphonuclear leukocytes, macrophages, lymphocytes, and monocytes; increases in the adherence of bacteria to the respiratory epithelium; and decreased mucociliary clearance [14–19]. In studies of pneumococcal pneumonia in mice and squirrel monkeys, greater severity of disease and mortality resulted from infections due to pneumococcus and influenza virus together than from infections of either organism alone [20–21]. These animal studies sup...
Varicella (chickenpox)? Leads to Group A-hemolytic Streptococcal infection. Known affectionately as GAS, and exhibiting as
necrotizing fascitis.

researchgate.net/publication/12…VZV infection itself may cause a predisposing immune aberration or may allow invasion via another less apparent portal, such as lesions on the oral mucosa or the respiratory tract. In favor of an immune aberration is the fact that NF, the most severe manifestation of soft tissue infection, tended to occur more commonly in association with chickenpox than in nonchickenpox cases. Furthermore, Fujimara et al33 have presented evidence of a switch of the CD41 T cell profile in patients with varicella and underlying atopic dermatitis from a TH2 toaTH1 dominant type with a relative immunosuppressi...

I have my head so far up the governmental cow's butt on this one, I think I am uniquely qualified to answer on the difference between Biden and Trump on H5N1.

Ready for a🧵?
Biden's USDA is still denying airborne, and is still not telling the Spanish-speaking dairy workers that it is airborne. Or to wear an N95.

Biden's CDC is running Spanish ads on the radio and Facebook. Offering testing. Workers still not trusting the CDC.
Trump will get the CDC to continue to offer free testing clinics - and arrest the workers when they come in.

Nobody will want to milk or take care of the cows. They will continue to get sick, but really die without the intensive care they actually need with H5N1.

You go to the doctor to get better, not sicker.

There is a group called the HICPAC that tells the CDC what they should do regarding whether or not the guy with bright pink eyes in the bed next to you is wearing an N95 or not.

Whether your doctor comes back from Bermuda with
Covid - and either wears an N95 when he sees you or not.

Whether the hospital gives you attitude about your N95 - or joins you in wearing an N95.

They are going to vote today to say that Surgical Masks are Respiratory Protective Equipment - which is a lie. Per NIOSH/ OSHA.
What can you do?

Read this thread and then call the Inspector General’s office is very receptive. The direct phone number is 202-619-3148. Tell them the HICPAC did what is in that thread, and about them ignoring all airborne evidence.

The Canada BC teenager is in a hospital that barely uses surgical masks, under Bonnie Henry who screwed up SARS1, then C0V1D.

She thinks aerosols only come in cans.

⚠️ Trigger ⚠️

I am going to lay out the worst case for you. Going to get dark.
First, the subclade, or variant, that this poor kid has is D1.1.

It is not the dairy cow subclade - that is B3.13.

Good breakdown of what a clade is here:
cdc.gov/flu/about/viru…

D1 is lighting up the Pacific flyway.

33 outbreaks in 2.5 weeks.

x.com/0bFuSc8/status… Pacific flyway is basicallywedt of the western tip of Texas, Wyoming etc.
"Genotype D1.1 has:
• Eurasian HA, PB1, MP, NS – all ea3
• North American PB2 (am24), PA (am4), NP (am13), NA [am4(N1)]"

PB2 is not good.
