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…
Image
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...

This may be the biggest news of the decade. Completely overshadowed by shenanigans in the White House.

It looks like H5N1 reinfections are entirely possible. This means that our farms are going to be a never-ending circulating pump of H5N1.

This. Is. Not. Good.

/1 But reinfections suggest that the virus, called H5N1, could circulate on farms indefinitely, finding opportunities to evolve into a more dangerous form — a “high-risk” scenario, said Louise Moncla, an evolutionary biologist at the University of Pennsylvania. “You could easily end up with endemically circulating H5 in dairy herds without symptoms, obscuring rapid or easy detection,” Dr. Moncla said.
How long can our luck go on?

We now have Bobcats with the one mutation that we really don't want to see.

The PB2 E627K mutation.

"The PB2 E627K mutation is a dominant adaptation marker in most human-adapted influenza A viruses. " PB2 E627K is a mutation in the PB2 gene of the influenza A virus that changes the amino acid glutamic acid (Glu) to lysine (Lys) at position 627. This mutation helps the virus replicate more efficiently in mammalian cells. How it affects the virus Replication: The PB2 E627K mutation helps the virus replicate more efficiently in mammalian cells. Disease severity: The PB2 E627K mutation can cause more severe disease in mammals. Temperature: The PB2 E627K mutation helps the virus replicate in the lower temperatures of the upper respiratory tract of mammals. How it affects humans Human-adap...

If you are taking public transport like in NYC? Mask up.

Pretty cool Master's Thesis for Biology - on bioaerosols like SARS-COV-2.

Set up a prototype aerosol sampler?

And find it in 52.9% of the samples in Beijing Railway Station and 44.4% at Beijing Subway Station.

/1 The subway station selected for this experiment was Xidan Subway Station, a major subway station on Lines 1 and 2 in Beijing and serves as an important subway transit hub. The passenger flow of the station is expected to be around 7,000 – 12,000 during rush hours and less than 7,000 during non rush-hours. A total of 27 samples have been collected, with the first 10 collected around 9-10am in the morning or 3-4pm in the afternoon, which is considered non-rush hour and 17 collected during the rush hour period. Sampling was collected for 17 weeks in total, not necessarily consecutively taking ...
Bioaerosol Sampling in the Exit Area of Beijing Railway Station. BC500 was placed near the exit area of the Beijing Railway Station where passenger flow is expected to be the largest. Beijing Railway Station is one of the oldest train stations in Beijing with a large passenger flow that is around 60,000 passengers per day. The bioaerosol sampling device in this scenario is placed at the exit area of the train station, where passenger flow is relatively higher, ensuring better chances of sample collection. However, passenger flow, unlike the subway station is not divided into rush / non-rus...
Never mind this.

"Firstly, the high positive rate highlights the potential for airborne transmission of these viruses in crowded public areas"

Definitely do not flag this to anyone in a big city looking to ban masks.

Definitely do not do that with this new study. The findings of the experiments conducted in this thesis indicate that viruses including SARS-CoV-2 and influenza are not only present but also potentially widespread in these public spaces, which has several important implications. Firstly, the high positive rate highlights the potential for airborne transmission of these viruses in crowded public areas. This is consistent with existing literature that suggests densely populated environments with limited ventilation can facilitate the spread of respiratory viruses. The detection of multiple pathogens reinforces the importance of considerin...
Yes, nothing to see here.....

At Beijing Railway Station, positive samples were
52.9% SARS-CoV-2
47.1% Flu A
23.5% Flu B.

At Xidan Subway Station, positive samples were
44.4% SARS-CoV-2
18.5% Flu A
7.4% Flu B At Beijing Railway Station, 52.9% of samples tested positive for SARS-CoV-2, 47.1% for influenza A, and 23.5% for influenza B. Additionally, 29.4% of the samples were positive for two pathogens, and 11.8% were positive for all three pathogens. The total percentage of negative samples at this location was 29.4%. At Xidan Subway Station, 44.4% of the samples tested positive for SARS-CoV-2, 18.5% for influenza A, and 7.4% for influenza B. Moreover, 18.5% of the samples were positive for two pathogens, with no samples testing positive for all three pathogens. The total rate of negative samples ...

Sara Anne Willette's visualization tool - is not a list. It is a visual representation of a group of accounts, so that she can remove herself from them.

It uses only publicly facing data, available per the X TOS, and the API, not scraping.

IT WILL NOT EFFECT YOU AT ALL. Image

There are some accounts 👇 and their followers that SHE JUST WANTS NOTHING TO DO WITH.

It is her choice to remove herself from any account she wants.

The actual data?

✔️ account creation date
✔️ the username of the account,
✔️ who they follow.

All obtained legally per TOS. The list. Ooo so scary. You all are acting like high school kids.
Describes user name
The LOCATION that you saw in the blurry used to get you all fired up!?

Picked up from the front page of the profile, but NOT USED.

I live in Temporarily Enabled, USA - but it is not my physical location.

That's it.

Ozone. A pollutant no matter where it is - outdoors or indoors.

#DYK that indoor inhalation is 25% to 60% of total intake? Per Weschler?

iaqscience.lbl.gov/increases-ozone

#DYK that MOST indoor ozone comes from OUTDOORS? Per Weschler?

pmc.ncbi.nlm.nih.gov/articles/PMC16…

Truly worried?

🧵 Accounting for the differences between indoor and outdoor air ozone concentrations, Weschler [6] has estimated that indoor exposures to ozone are typically 45% to 75% of total exposures. Because breathing rates are lower when people are indoors, the indoor inhalation intake of ozone is typically 25% to 60% of total ozone intake. These estimates may be low for the population most affected by ozone—infants, the elderly, and those with respiratory and cardiovascular disease. Consequently, if there is no threshold concentration for the health effects of ozone, or if the threshold is low, roughl...
Although there are indoor sources of ozone, in most buildings indoor ozone has been transported from outdoors (Weschler 2000). Indoor ozone concentrations track outdoor concentrations with a slight time lag that depends on the air exchange rate. Ozone is removed by indoor surfaces as well as by gas-phase reactions, and hence, indoor concentrations tend to be smaller than co-occurring outdoor levels.
If you are TRULY worried, you should be focused on eliminating ozone, right?

You would be slipping into people's threads and sharing these cheap DIY activated carbon builds, right?

Because if you are TRULY concerned about ozone, you would not be slipping into threads of people showing pictures of their new FAR-UVC Torches - for any other reason, but to share the good word that the miniscule ozone generated could be eliminated.

VIRUS and OZONE free air.

ACH ACPH - Air Exchanges per Hour.

An important topic since way before 2020, but given fresh vigor with our collective interest in clean air. Not just disease free air, but VOC, PFA, microplastic, mold, UFP, PM 1, PM 2.5, etc.

The outside air will infiltrate inside.

That ☝️picture is not typical.

Typical ACH - there can be general estimates, but every house is different. You can determine your own, as shown by @jljcolorado with help 👇👇. Jump to the section shown 👇.

I am grateful for input and suggestions on this topic from Andy Persily, Shelly Miller, Dustin Poppendiek, Ty Newell, Rich Corsi, Bill Bahnfleth, and Jeff Siegel.
The thread about that article is here. Some excellent discussion on it by some very good scientists, including those Dr. Jimenez acknowledges. Those folks are also on Xitter.
