It will be a miracle if H5N1 does not go full explosive pandemic.

I actually spent a chunk of time trying to figure out how to get OSHA involved.

🧵 on what THEY know, and TRANSMISSION.

tinalexander.github.io/notes/2024/06
So, the USDA wants you to not be worried. They EXPECTED numbers to go up.

But they forgot to tell their boss, @SecVilsack, who says it will be isolated and burn out, because they have biosecurity plans available, and understand how it's transmitted.

agriculture.com/usda-aims-to-i…


We do see it as kind of a naive population where we see those numbers go up that’s expected. That’s not necessarily alarming in the sense of we understand how this disease spreads. However, to get really further ahead in this space. Again, it goes back to the biosecurity we’re really wanting all industries all to really up their biosecurity, have those enhanced biosecurity plans. We do have through our funding mechanisms, again, options for unaffected, as well as affected herds to both be able to increase biosecurity plans on site to one, keep disease out of their herds. And two, to keep d...
“We are trying to essentially corner the virus” within infected herds so it eventually dissipates, he said during a teleconference.
The USDA’s strategy against bird flu in dairy cattle is to identify infected herds and wait for the virus to die out within the herds, said Agriculture Secretary Tom Vilsack on Monday. “I’m confident we have a good understanding of the virus and how it is being transferred,” he added.
He said that on June 4th, and when there were 80 herds, 9 states.

Now, there are 97 herds, 12 states.

Their preventive measures have been in place since May 1.

THEIR PREVENTIVE MEASURES ARE NOT WORKING.

Why? We have to know HOW it is transmitted.

A reporter asks the task force - obviously, you think contaminated clothes are the source.

Here's a good synopsis of the Michigan report they mention. That synopsis mentions that it would be good to implement the Secure Supply Biosecurity Plan.
. michiganfarmnews.com/usda-releases-…

I saw in the Michigan report, it talked about shared workers being that only transmission link between dairy and poultry. I mean, have you looked into the possibility that infected workers were the vector? Or is there a reason that you think contaminated clothing is more likely? Thanks.
Image
USDA APHIS replies that they know that shared clothing is a risk factor.

Got that - just a risk factor. We'll come back to that because I went digging.

@USDA_APHIS then goes on to state that they DEPEND ON PUBLIC HEALTH TO TELL THEM IF PEOPLE ARE INFECTED. I saw in the Michigan report, it talked about shared workers being that only transmission link between dairy and poultry. I mean, have you looked into the possibility that infected workers were the vector? Or is there a reason that you think contaminated clothing is more likely? Thanks. Kammy Johnson, APHIS [00:20:22] That’s a great question. And thank you for bringing that up. When we look at those genetic sequences, we do see that there are relationships and between those viruses, and we are relying on our public health colleagues to tell us and have some indicator on whether or not pe...
45 people have been tested. Total.
Across 12 states and 97 farms.

So, the USDA is telling us not to worry because they are depending on public health to test people to let us know if it is spreading in people.

Who are not being tested.

cdc.gov/bird-flu/h5-mo…
Image
Not coincidentally, did you know that 10% of poultry workers test positive for H5N1?

Per @NIOSH, in DHHS (NIOSH) Publication Number 2008–128



"Protecting Poultry Workers from Avian
Influenza (Bird Flu)"

In which they recommend respirators or PAPR. cdc.gov/niosh/docs/200…

Image
Image
Which brings us back to the vaunted @USDA_APHIS Secure Supply "No respirators required" plan from 2017 👇.


Image
Did you notice that @USDA_APHIS actually did NOT ANSWER if infected workers were the reason for the spread? Image
They just focused on the clothes.

But speaking of clothes - is it because your pants leg sneaks up into your nose?
No. It's because virus contaminated aerosols (dust, respiratory, fecal, milk - all possibilities) land on your clothes.

As you move, or wind hits them, they resuspend into the air., and they get inhaled.

This is why Secure Supply has Tyvek coveralls.

NIOSH also has Tyvek Image
coveralls. But NIOSH ALSO HAS RESPIRATORS, AND has a full on donning and doffing procedure. It is deliberately designed to lower the risk of inhaling those aerosols as you take off the overalls, gloves, boot coverings.

Remove clothes, coverings with respie and goggles on. Image
Then remove goggles and respirator. Wash hands. Image
Shower. Image
And that is just for clothes.

Respirators are also so workers don't inhale the aerosols straight from the dust, cow breath, dried fecal particles, milk aerosols.
When we turn to the vaunted Secure Supply BIOSECURITY website for dairy producers, not a respirator in site.

More examples....

So, I am really at a loss as to get someone to change that Secure Supply website done in 2017 in light of the airborne aerosols of H5N1.

@CorsIAQ, I couldn't help notice that UC Davis was one of the contributors.

Any chance you can gt that dept to reach out?

Cheers either way!
Image
Image
@CorsIAQ Almost forgot - an assumption that @USDA_APHIS is making.

That public health will be able to have some indicator if people have been infected.

There is no such guarantee. There will be asymptomatics. Presymptomatics. Symptoms like SARS2.

I was wrong. I said 97.

104 herds infected.

From 36 on May 1st which is when all of their current mitigations were all in place.

At what point, @Alexander_Tin @HelenBranswell, for the USDA and CDC, do they say the current strategy is not working?

Is this considered success @SecVilsack ?

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"

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.
