I'd like to invite you to go scilunking with me.

What is scilunking? It's spelunking within studies.

First cave we enter, Dr. Gurdasani's headlamp shows us that kids infect each other...and their parents.

This is a great thread! Read it, then come back for .... gold!
Her second tweet had this study. A genomic tracing study and confirmation of transmission within schools.

wwwnc.cdc.gov/eid/article/27…

But something in this cave caught the corner of my eye.

A furtive movement.

"most school-associated cases are acquired outside of school"
Hoeg.

A cold wind blows from the depths of the cave.

Dare we?

"Hey, I was promised GOLD, not HOEG!"

You are right, let's go deeper.
ncbi.nlm.nih.gov/pmc/articles/P…

Our headlamps have found gold! 37% less transmission in school!

Where will you spend yours?

Wait a second though. There's something off about this gold.

It's fool's gold.
✅ Kids are often asymptomatic.
⚠️Absence of child to staff transmission does not mean transmission in school is uncommon. We'll come back to this.
⚠️ Reference #5 says asymptomatic attack rate is only .7% within household, so we are to believe kids don't transmit.
So, we move sideways into that cave, and we see what that study says.

jamanetwork.com/journals/jaman…

It says asymptomatic index cases are .7%.

Which means the first person found to be infected was asymptomatic.

Does not state if child or adult.
Were children actually addressed?

Yes. Data was limited, but a study was found indicating relatively high transmission from kids!

The exact opposite of what Hoeg tried to fool us into believing!

And thus, we have our fool's gold.
Remember I promised to come back to child to adult transmission?

About that. Hoeg's study was in Wood County, Wisconsin, September-November 2020.

Guess what they had in school?

Teachers and students wearing masks.

In rural Wood County, did they have a mask mandate? Yes.
Technically.

The state was under a mask mandate.

But the sheriff said there would be no enforcement.

waow.com/2020/07/31/lis…

So, in all likelihood, there was much less mask wearing in the community than the 92-97% mask wearing in the school.
And for sure there was no cohorting, etc. in the community.

But all of those NPI's were in the school.
And this is the real gold from this scilunking expedition:

NPI's work.

Ebola - it's not all about respiratory aerosols.

DYK that you, and me, and everybody are Pig Pen from Charlie Brown?

We shed our entire outer layer of skin every 2-4 weeks, about 500 million cells daily.

Your corneocytes (outermost cells) lift off of your body with the
gentlest of micro-air currents. Like a leaf picked up off the ground for the briefest of moments in fall.

They act like 12 micron aerosols in float time, but 25% of total skin flakes are sub 5 microns...and you know what that means. Deep deposition - or shallow as
sub 5 likes to also deposit in the nose.

It's funny...I embrace push-back in debate. Tightens up my game.

Imagine if those skin flakes now have Ebola on them?

Two studies show that Ebola literally oozes through the skin - both ways. In and out.

Not shown in vivo, but

The WHO forbids contact tracers from masking or gloving up.

"Do not conduct home visits wearing personal protective equipment like masks, gloves, or
gowns."

It gets worse. Do not conduct home visits wearing personal protective equipment like masks, gloves, or gowns.
They have a handy how to reduce risk of catching ebola at home.

It even has 5 masks listed on it.

But not for the other family members.

"7. If the patient has vomit, diarrhoea or bleeding, a mask or a dry towel wrapped around the face can be used to protect the nose and mouth Image
7. If the patient has vomit, diarrhoea or bleeding, a mask or a dry towel wrapped around the face can be used to protect the nose and mouth when touching the patient or items soiled with blood or body fluids. A waterproof gown, eye protection, gloves and rubber boots should also be worn in these circumstances.
Here are the 5 face masks. Image

The "epidemiology" of Ebola tells us that it's not airborne. You've heard this over and over.

What drives it? The questions on the contact tracing form.

Quick 🧵. Image
COVID - the WHO and CDC said it wasn't airborne via aerosols, right?

The CDC said it was spread person to person via close contact - within about 6 feet.



And you remember it took FOREVER to get changed.

The contact tracing form was web.archive.org/web/2020032817…Image
Image
arranged around close contact. These are the questions driving the stats of how many and how are infected.



So, the CDC will only hear back what it's asking. This was the epidemiology of COVID - until it wasn't. web.archive.org/web/2020052514…Image

Speaking of silly, can we agree that the WHO has Ebola experts?

Let's talk about PPE, and a bias towards "less PPE is better." Image
The WHO EBOLA IPC guidance:


Foreshadow on PPE

"...due to the desirability of an off-
the-face design, and not for protection from aerosols, respirators may be used instead of medical masks"who.int/publications/i…
If you can stay 3 feet away while screening? No medical mask needed. Image

Great article by @EmilyJoshu here.

Emily, there's another article in this that's even more shocking.

The aerosols from milking have long been discussed by many of us on X.

People like myself, @sri_srikrishna, @AbraarKaran have long advocated for comfortable aerosol
protective gear like PAPRs. But, have been ignored by the USDA who, of course, thought it was only contaminated milking gear like the claw.

But there is one more source of aerosols besides cow breath.

The wastewater. When you spray anything you generate huge amounts of Image
aerosols. And that farm wastewater, filled with milk dumped from being full of H5N1, gets reclaimed and reused.

Those milk and wastewater lagoons are on most dairy farms (my grandfather owned a dairy farm).

And there's something you should know.

Humanity's hubris vs the precautionary principle.

The virus, ANDV, will do what it will do. Pandemic? History tells us "NO." But history is in the past.

Let me show you what the studies tell us - and why I am livid that the WHO is insisting that surgical masks are ok.

🧵
Incubation time, or how long until symptoms show up?

The high risk time frame is 14–32 days. Not to put too fine a point on that, but that can mean a full month later

pmc.ncbi.nlm.nih.gov/articles/PMC32…

There have been some out to 8 weeks, but let's ignore those

gov.uk/guidance/andes… Image
Clinical features The most important complication of ANDV infection is HCPS, which is associated with a high mortality rate. Milder illness without significant cardio-respiratory compromise may also be seen. Illness usually develops 2 to 4 weeks following exposure, but incubation periods as early as 4 days and up to 8 weeks have been described.
But, what receptor does the ANDV attach to?

PCDH1 (protocadherin-1) is primarily expressed in the airway epithelium of the respiratory system, especially in the bronchial and nasal epithelial cells, and in pulmonary endothelial cells.

So, that means in the URT and the LRT.
