#EbolaIsAirborne
Ebola is airborne.

H/T @AeonCoinb for below.

Quick 🧵.

We are, after all, just evolved primates.

ncbi.nlm.nih.gov/pmc/articles/P…
Cynomolgus macaques - the unfortunate golden primate perfect for respiratory virus transmission studies. CoVid was found to be airborne long before the monkeys at the @CDCgov decided it might be.

Also airborne here.

Still monkeying around.

Clinical progression includes diarrhea and vomiting.

Vomiting Larry, seen below, indicates you need to clean up to 24 feet away.

Yeesh. Stuff of nightmares.

journals.sagepub.com/doi/full/10.11…
Bioaerosol Sampler captured aerosols during vomiting.

journals.plos.org/plosone/articl…
Not going to bother with diarrhea, except to say Ebola virus has been found in stool samples, and toilet flushing has been amply studied and proven to generate infectious aerosols.

Moving on.
Next, is a study by Dr. @brosseau_lisa. She has forgotten more about airborne transmission than most will learn in 10 lifetimes.

sci-hub.hkvisa.net/10.1097/jom.00…
So, is Ebola airborne?

It is possible, plausible, probable, and yes, certainly airborne via aerosols.

If you screenshot this, and cry it is not? Then, you need to put down the ID textbook, and pick up an Aerosol textbook.

Or....
Put on a face shield, and go volunteer in Uganda.

A face shield will stop all droplets.
#EbolaIsAirborne
Another group of scientists invented another Vomiting Larry to test aerosols.

A million aerosols spewed out. At least 13,000 virus aerosols (virusols) included.

Oh, we are cooked. Just cooked.

"Brain Mitochondrial dysfunction, known for ~20 years is finally recognized as a central upstream driver of Alzheimer’s disease (AD), not just a downstream effect."

And SARS2's targeting of mitochondria is well-known.

Even in the brain.
/1 We identified dysregulation of mitochondrial and synaptic pathways in deep-layer excitatory neurons and upregulation of neuroinflammation in glia, consistent across both mRNA and protein. Remarkably, these alterations overlapped substantially with changes in age-related neurodegenerative diseases, including Parkinson’s disease and Alzheimer’s disease. Our work, combining multiple experimental and analytical methods, demonstrates the brain-wide impact of severe acute/subacute COVID-19, involving both cortical and subcortical regions, shedding light on potential therapeutic targets within pat...

@neiljshaw - — a few tips on your excellent article from a clean air advocate

"Consider Wearing a Mask" ?

No, "It is incredibly important to wear a well-fitting mask such as a N95, KN95, or KF94, for the best protection."

You two are doing Image
public health with this article.

Public health is best done with simple clear instructions.

No:
"These masks act as a barrier, reducing the spread of respiratory droplets when people talk, sneeze or cough."

Yes:
"These masks act as a HEPA air cleaner for the face,
cleaning the air of respiratory aerosols when people breathe, talk, sneeze or cough."

The barrier carries the idea of an immovable wall. Unable to be penetrated by things like oxygen and CO2 - which feeds antimaskers.

As an who debunks antimaskers, it is

As an anonymous clean air advocate, I've put a bit of thought into how to present, well, my expertise.

If someone were to say, "How do I know you know what you are talking about? Are you a doctor, or a virologist?"

To which, I would say...."No, but that's a good thing.
/1
I have focused on aerosol and masking science. Because it is those fields that give us the most information on how airborne particles, aerosols, get from Person A to Person B.

My expertise is derived from the great studies of Dr. Lindsay Marr, MacArthur recipient. Dr. Prather,
double National Academy member, Dr Milton, inventor of the Gesundheit, aerosol scientist and medical doctor; Dr Coleman whose group found that duckbill N95s captured 98% of emitted respiratory aerosols, and more excellent individual aerosol scientists.

I am not a fan of nasal sprays to stop The 'Vid, but I respect you having it as a layer in the Swiss cheese package.

But, some people have said they got bloody noses.

While at the ER yesterday, I picked up a pretty good at home technique. Let our $1,000 lay-out
Image
save you money.

Use tongue depressors to make a nose pinch clamp.

Leave it on for 30 minutes. Still a problem? Two sprays of Afrin, and re-apply nose pinch clamp. Wait 30 minutes.

Still a problem? Cotton balls sprayed with Afrin, clamp, 30 minutes

Afrin- in generic form is $3.32 at Walmart.

Also, put a ice compress at the back of the neck, while doing the above.

"Cooling the nape of the neck is said to induce reflex constriction of the mucosal vessels of the nose"

✅ I agree with the authors.

A study demonstrated 100% PERFECT protection against SARS2 w/ readily available KF94s

✅ 181 HCWs
✅ 1 got SARS2 antibodies, but an epi investigation -> the infection happened elsewhere.
😡 The final checkpoint was March 2021. N95s only became freely available 1 month later
/1 FDA: N95 masks, now plentiful, should no longer be reused By MARTHA MENDOZA and JULIET LINDERMAN (Associated Press) April 23, 2021 12:44 p.m. Medical providers may soon return to using one medical N95 mask per patient, a practice that was suspended during the pandemic due to deadly supply shortages
What is described in the tweets
in the USA.

Korean study:
jkms.org/DOIx.php?id=10…

This is in comparison to a Swiss study during the same rough time-frame. A study which did NOT show the same excellent results, but dismal results. Why?

The Swiss had the same sort of fit testing,

pubmed.ncbi.nlm.nih.gov/35123572/ Results: We enrolled 3259 participants from nine healthcare institutions, whereof 716 (22%) preferentially used FFP2. Among these, 81/716 (11%) reported a SARS-CoV-2-positive swab, compared to 352/2543 (14%) surgical mask users; seroconversion was documented in 85/656 (13%) FFP2 and 426/2255 (19%) surgical mask users. Adjusted for baseline characteristics, COVID-19 exposure, and risk behaviour, FFP2 use was non-significantly associated with decreased risk for SARS-CoV-2-positive swab (adjusted hazard ratio [aHR] 0.8, 95% CI 0.6-1.0) and seroconversion (adjusted odds ratio [aOR] 0.7, 95% CI ...
PPE monitoring.

What was the big difference?

Are N95s/FFP2s inferior to KF94s?

No, it was supply - and other reasons.

@tomhanks has just been savaged by people screaming masks don't work.

All hospitals have fiduciary responsibilities to not waste money.

Here is a light sampling of hospitals mandating masks because they work.

Proving that not only do masks work, but mask mandates work.
