Logically, mechanistically, and as shown in studies.

This pic below? The WHO is trying to get ahead of this one.

Unfortunately, for them, has the right stuff to blow down their house of cards. scholar.google.com
Image
A little dark humor to start, because, really, how many lies do we have to catch them in?

(As always, I am fan of public health. Not a fan of political health as the CDC is under Walensky and Redfield).

First study...

Approximately 90 minute viability in the usual Goldberg drum. At a very rough glance because this first step of the dance is boring.

Anywho, MVD is not very stable, thankfully.

As seen below, aerosol transmission possible.

mdpi.com/1999-4915/14/4…
Image
Next... Our monkey pals. Does MVD cause damage to the lungs, where aerosols are produced?

Not at first, but we see filoviruses like MVD use the aerosol route.

Later on, we see the lung pathology. Lots of it.

Yes, lungs involved (aerosols).

mdpi.com/1999-4915/8/4/…

Another bunch of monkeys.

Exposed to aerosolized MVD. Died.

Establishes that if virus gets into URT or LRT, can cause infection in nonhuman primate.

Also, this breed is a very good stand in for humans in respiratory disease testing.

We die, too.

journals.sagepub.com/doi/full/10.11…
Image
Same study... inhalation is not a "prominent" method of transmission.

But it is possible.

So, if there is a remote possibility of me catching a disease with 50% fatality?

You can bet that your boy will be in a 3M 6800 full face N100.

And so should you. Image
Symptoms of Marburg include vomiting.

Guess what generates huge amounts of aerosols? (Vomiting - don't tell @RWalensky, let's let it be a surprise.)

cdc.gov/vhf/marburg/sy…
Image
Symptoms also include coughing. Thank you, Mayo Clinic.

Guess what generates huge amounts of aerosols?

Coughing. (Fine - breathing, talking, laughing, singing, all produce aerosols.)

mayoclinic.org/diseases-condi…

We can take a look at our villian's origin story. Oops, they said aerosols.

That will disappear soon. Web. is our friend!

cdc.gov/vhf/marburg/tr…

Something to consider. The @CDCgov and @WHO's contact trace methods are based on direct contact.

They wouldn't know how to use the Gesundheit 2 to save @DrTedros's reputation. Or how to do full traces, including everyone in the room. Or in the next room.

To use smoke.
So, all of those epi studies?

About as useful as @RWalensky 's magical 5 day isolation policy, when trying to rule out airborne transmission.

How about this? You nay-sayers, explain the origin of the 6 foot distance rule. The 15 minute transmission rule used today.
I can explain where they come from, can you?

Sorry if I am being aggressive.

We have sat around for far too long. I am calling it like I see it, and it's all self-reinforcing bullshit.

I am talking directly to you, John Conly and others of his ilk.

Get out of the damn way.
Let me show you what I mean by self-reinforcing.

In this fascinating treatment of a lost case of Marburg, the authors explore how the wife got infected.

ncbi.nlm.nih.gov/pmc/articles/P…
Image
Notice how they did not discuss the fact they were breathing the same air?

Instead, they bent over backwards to pull a sexual event out of a medical article written after the fact.

Which just might have been crass boasting.

Who knows?

In any event, our attention is now
focused on sex and fluids.

Ignoring the 22,000 breaths they took back then per day - and we all still take (H/T @kprather88 for that fun factoid).

One final note for now.

Elite Panic. That is when the elite panic that the common person will freak out.
Let's stop that, right the eff now, @RWalensky @ashishkjha. Enough. Grow up.

Just tell us the truth. Because they did that here 👇👇. And it went just fine - when they were matter of fact.

When they told half-truths, as in Germany 👇, people lost their minds. Image
Oh, btw?

It's also transmitted all the usual ways as well.

Sexually, fomites, droplets, butterfly kisses (eye to eye).

But fortunately, it's just not too transmissible.
Not yet.
I sure did. Unlike the CDC, I don't delete uncomfortable truths.

(Though I believe my godforsaken Autocorrect did that to me.)

But - it is my responsibility, so my apologies!

Thank you, @Lysistrata2022

Tacking on #MarburgVirusIsAirborne
#MarburgVirus

Not sure what the first tweet's Marsburg is all about....
#marburgisairborne
Never mind this Marburg Virus update.

It's just the Department of Homeland Security saying it can be transmitted via aerosols.

dhs.gov/sites/default/…
MARV can be directly transmitted via blood and other bodily fluids. The virus may also transmit via aerosol and fomites; however, the stability of the virus is not well understood. • Limited data on MARV stability may be supplemented with available data pertaining to EBOV, as both viruses are members of the family Filoviridae and primarily transmit through direct contact. • EBOV maintains infectivity in whole blood and plasma after 5 days, even when the blood is stored at 37°C. • EBOV loses all infectivity in urine and semen at 37°C within 4-5 days and 5 days, respectively. • EBOV remains...

AVERAGE CO2 in the dead space below an N95? 1-3% - or 10,000 to 30,000 ppm. Scary?

No. You see that's the average.

Humans have focused on average or peak exhalations/waveforms.

We haven't studied the LOW POINT with capnography.

We have done it with simulations. Image
There are no published experimental (human) capnography studies inside N95 dead space that show the CO₂ dropping down as low as ~0.4% within a single exhalation. Human trials typically measure peak or average values rather than full breath waveforms.
As you can see, the amount of CO2 in the N95 goes down.

Why? Because the air around us has so much less CO2. When we inhale, it mixes with that high CO2.

Dilution and diffusion both at play.
journals.plos.org/plosone/articl…Image
As all of us who has ever worn a mask/N95, which is most of the world, knows, we don't suffer the effects of inhaling 30,000 ppm all day.

Lets look at this a different way.

What if we were in a room with huge CO2? That's what antimaskers are implying is going on.

How NOT to Science. A time travel thread and magic.

This is Helmut Traindl - the engineer who devised the procedure behind Walach CO2 study that was retracted after 16 days:
jamanetwork.com/journals/jamap…

Then, republished by Dr. Domingo just 6 months later.
sciencedirect.com/science/articl… Image
@RetractionWatch had an interesting write-up on how it was republished by Dr. Domingo.

It rings of plausible deniability. Except it smells vaguely of bad faith.

retractionwatch.com/2022/08/01/one…Image
Turns out that @TecnATox was founded, and is directed by Dr. Domingo.

You'll be hearing from me, Dr. Domingo - and a rather lot more people, once I get done writing all of this up.

You see, I found the pilot video.

So, in your apartment or hotel, we saw below how its heated facade, or front, could drive your downstairs neighbor cough into your lungs.

Let's step inside your living room now, and step forward in time to winter.

What happens if your sick neighbor is seated in that living /1
room?

Where is the worst place for them to be seated if you have your heat coming from a heat register up on the wall?

Next to your cold window.

The cold air cools your sick neighbor's exhaled infectious air, and drives it to the ground.

Where it sidles along until Image
Image
you and your family's bodies' thermal plumes pick up that air, and lifts it up to your faces to be breathed in.

Or....to put this in another way....if you go to a coffee shop as I like to do, and you see someone coughing next to a cold window? Do not dawdle.

Leave.

I looked at your thread @moog77 . The reason that epidemiological didn't work (cases continued to go up)? Is the same reason the 2023 Cochrane fails, ironically, after you touted it as the "gold standard."

Not because clean air doesn't reduce cases. It empirically does. It
just doesn't do it where it's not being applied.

What do I mean?

2023 Cochrane "the gold standard" - for community masking is based on a few studies.

One is Alfelali (2020) set in the Haji season

Do you live in an apartment or stay in hotels?

Got a "oops, outside air can get you" study. Coming out of Beijing University of Technology - taking airborne transmission seriously.

They rented 50 rooms of a building. Did some very cool CFD work - then, be still my heart, Image
followed it up with tracer gas experimentation.

See room 303 above? 403 and 503 got whatever came out of 303.

With studies like these, there are so many variables. But, if I lived in an apartment, I would set have at least a PC fan CR Box next to those open windows.
Or an HRV set up in that window. And for sure a PC fan CR box next to the front door for under the door airflow.

Not HRV, but equally valid

Swimming and showering.

Below is the thread of collected "swimming/ showering safer in indoor shared air" solutions, so far.

You might be thinking that the chlorine smell protects you near the pool. Chlorox is great.

But you would be thinking incorrectly.

Thread. Filti media wrapped out an inside brace made out of zip ties. Laugh all you want, but it works, yo.
Have there been indoor swimming pool transmission events? Yes.

jamanetwork.com/journals/jaman…

pubmed.ncbi.nlm.nih.gov/34606662/

And more.

Were they in the swimming pool or in the more likely shower/ locker rooms or lobby? Nobody has teased that out.
You do not smell chlorine gas in the pool. If you were actually smelling real chlorine gas, you had better start running for the door.

You are smelling trichloramine - from sweat, urine, body oils when there is not enough free chlorine.

frontiersin.org/articles/10.33…“It is a common misconception that a strong chlorine odor is caused by too much chlorine in the water. The odor is actually caused by chloramines (combined chlorines) off-gassing from the pool water surface. Chloramines are formed in the pool water when there is insufficient free chlorine in the pool to address the nitrogen-containing compounds brought into the pool water by the swimmers. These nitrogen compounds are naturally occurring and contained in sweat, urine, body oils, and other proteins that get released into the pool water. If the introduction of these nitrogen compounds outpace...
