Doctors and nurses get infected in their own hospitals unfortunately.

But there is one hospital in America that has had zero of these infections in over 25 years.

Not one single doctor or nurse in that hospital has been infected.

Not one.
Would you believe that it's a hospital dedicated to an airborne disease, tuberculosis?

The Texas Center for Infectious Diseases, while not a large hospital, does have 170 employees.

In 1996, they gave everyone reusable N100 elastomeric respirators.

Image
Since then, no Hospital Acquired Infections. And - they saved a ton of money by using them instead of N95's. Image
Not only do they save money, but the respirators are very comfortable. I wear a 3M version myself, and they are so much more comfortable than scratchy FFP3's.

They are also much more protective: Image
And the HCW's loved them; Image
I understand if this sounds too good to be true. Here's their website:



At the bottom of that page, is their Respiratory FAQ:


Here's their contact info: dshs.texas.gov/tcid/default.s…
dshs.texas.gov/tcid/Respirato…
Image
Here's the same basic story on this hospital, for your verification purposes:

Late addition to this surprisingly popular thread:

Regular folks wear them, too:







Look for N100.
Patientknowhow.com
cleanaircrew.org/elastomeric-re…
One more addition...Nicolas has forgotten more about respiratory PPE than you can shake an N100 at.

Absolutely endorse this webinar.

This is the viral TB hospital thread where no HCW has caught TB because of elastomeric respirators.

And it now has happened for CoVid.

And yet another zero nosocomial transmission of airborne diseases for HCWs.

Finland, FFP2/FFP3.

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.

@mvankerkhove - a follow-up question on today's press conference.

In this bit, you were thanked for being very clear.

But, you said that the medical personnel taking care of those sick would be wearing PPE.

N95s are not PPE. They are Respiratory Protective Equipment. /1
Surgical masks are PPE.

So, is the WHO advising them to wear surgical masks or N95s/FFP2/KF94/KN95 (respirators)?

Second followup, @mvankerkhove, you referred to "really close contacts"

Close contacts are defined by the WHO as within 3 feet.
Cases 1 & 2 were close contacts.

How did the other cases get it? I realize you cannot possibly have an answer...but you are labeling this as "really close contact" for those cases - as well.

Staterooms are typical 2 person rooms.

It doesn't add up. Image

I've become a bit of a Dental Nerd after just getting savaged by avoiding the dentist due to COVID.

But, now, I have a Dental Nasal PAPR, know all about Stephan's Curve, use a waterpik, Oral-B iO Series 10, chew 8 pieces of xylitol gum - and the dentist just said that.....
He has never seen anyone reverse course so perfectly before.

"Immaculate."

And bonus...I ran into a fellow masker in his lobby!!

She had never heard of Readimask, so I was super happy to share the Good Word with her.

Sharing the Good Word - not COVID!
Good point.

Now, this is a very interesting PREPRINT.

We've all heard that shingles vaccination reduces risk of Alzheimer's.

And we all know that Covid increases the risk of Alzheimer's by 50-80%.

What happens when you mix them? Will the vaccination offset a different disease?

/1 Opposing effects of SARS-CoV-2/COVID-19 infection and recombinant zoster vaccination on the risk of late-onset Alzheimer disease View ORCID ProfileCarly M. Rose, Shiying Liu, View ORCID ProfileWilliam S. Bush, Jonathan L. Haines, Scott M. Williams, View ORCID ProfileDana C. Crawford N3C Consortium doi: https://doi.org/10.64898/2026.01.21.26344555 This article is a preprint and has not been peer-reviewed [what does this mean?]. It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice.
Yes.

But by how much? Conclusions and Relevance SARS-CoV-2/COVID-19 infection and recombinant zoster vaccination are modifiable risk factors for LOAD among older individuals, with a modestly significant interaction between the two. Recombinant zoster vaccination reduced LOAD risk regardless of sex and race, though the protection is greater in those without documented COVID-19 infection. Recombinant zoster vaccination and reduced exposure to COVID-19 infection in the later decades of life reduce the risk of developing Alzheimer disease over at least a five-year period.
Useful for below - "Late-onset Alzheimer disease (LOAD; onset age ≥65)"

"odds of LOAD are 16% higher among those with at least one reported COVID-19 infection" Image
