This is a 🧵 that cuts through this CDC school guidance like the thread used in Netflix show "The Three Body Problem."

Their guidance will cut down the kids just like were cut down in the show.
Let's start with their tweet. It provides a framework to evaluate their actions against their words.

- preventing spread of infectious diseases.
-benefiting ALL students.
-maximize school attendance.

Let's start with preventing spread.

-Maximize school attendance
While preventing disease
Benefits all students is highlighted
The single most efficacious way to prevent the spread of infectious diseases is wearing respirators, as they stop both near and far field aerosols.

Are they mentioned in the intro page linked to? No. Masks are, but are buried.

People are logical.
cdc.gov/media/releases…

Teach and reinforce proper hand washing and respiratory etiquette. Take steps for cleaner air by improving ventilation in schools. Schools should consider ventilation enhancements and design when undergoing remodeling or when undertaking new building construction to optimize clean air. Clean, sanitize, and disinfect, when appropriate. Promote vaccinations for students and staff.
Long red arrow showing way down the page where masks are buried
They do the bullet points first.

Masking is not even in the bullet point sections.

PPE is in the 2nd group- for staff taking care of sick kids. Of course, this ignores the 58% presymptomatic transmission rate for SARS2, 38% for influenza.

Masks for kids are buried in the
"If illness activity is elevated, schools can consider implementing additional strategies"

section. Look at the action words...

Schools CAN CONSIDER implementing additional strategies.

Whoa! Your principal will be RUNNING to implement mask mandates. (Not mentioned). Image
"These additional strategies depend on several considerations, but include actions such as:"

What considerations? This is just such bad public health writing.

You don't say "there are several things" - and then not actually talk about those things. Image
Wearing masks are included with increasing space and distance between students and cohorts.

Really? The ONLY time that has been used in the US was during pandemics. (This does not include whole school closure for temporary outbreaks). Image
So, prima facie, the most effective NPI (NonPharmaceutical Intervention) is only listed in the pandemic section. And not even an effective version, masks, or the fact that mask mandates are necessary for wide uptake.

Especially in schools which are EVEN MORE subject to peer
pressure than adult society. (Mandates work by removing peer pressure).

But hey!

You can applaud the CDC because they actually mentioned the word masks.

✅ Everyone applaud the CDC for dropping the word into a page

You can. Not me.

Let's move on. Maybe it gets better? Image
Intro page here, but let's look at the quick (the fact) sheet



"Fact Sheet: Help Your Child’s School Prevent the Spread of Infections"



No masks found. Not in the pics.... cdc.gov/orr/school-pre…
cdc.gov/orr/school-pre…



Image

Image
Image
Not in the words

Instead it is respiratory etiquette, which....

Image
Image
Image
does not work.

Do little fingers magically stop aerosols from spurting from between them?

No. Neither do elbows.

And we DO NOT USE RESPIRATORY ETIQUETTE when WE BREATHE.

The @CDCgov is being so STUPID on this point.

In between the coughs? We all

still breathe. And we breathe about 11,000 liters of air every day.

A cough is about 2.3 liters of air. That is 5,000 coughs per day for respiratory etiquette to be used - if it actually worked, which it doesn't.

RESPIRATORY ETIQUETTE DOES NOT PREVENT OR SLOW TRANSMISSION.
But it is part of their main page to prevent or control the spread of infection.

As is Handwashing and Cleaning, Sanitizing.

Let me ask you a poll on this topic
Hand Washing Children washing hands at school Washing hands in school can help prevent the spread of respiratory and gastrointestinal diseases. Teaching and reinforcing proper handwashing can lower the risk of spreading diseases. Schools can set routines or scheduled opportunities for handwashing throughout the day. During times of increased illness spread or absenteeism, schools can evaluate hand hygiene routines and increase those opportunities. Schools could monitor and reinforce these behaviors, especially during key times in the day. Additionally, schools can provide adequate handwashi...

Wipe or soak up the blood or bodily fluid, clean, and then disinfect the surface. For more detailed information, see Cleaning and Disinfecting Your Facility.  Rarely, a school might need specialized or enhanced cleaning and disinfection for a particular infectious disease. This can occur when a new pathogen emerges and an ill student has been in the school space or an outbreak occurs with a specific pathogen like norovirus. Schools s...
Do we magically ooze viruses through our skin?
WHERE DO PATHOGENS PRIMARILY COME FROM?

Our mouth, nose, and anal orifices.

The anal orifice is covered by underwear and pants. A cloth mask.

The mouth and nose are not covered.

So, AFTER you wash and clean? Guess what gets dirty again from the uncovered mouth and nose?
Taking Steps for Cleaner Air leads off that page. Great. But masks should lead it off.

Oh SACRED BLEU! How dare I say that?

Ever hear of a hospital? Yeah, they have GREAT ventilation and filtration.

And they are still infecting lots of folks.

In fact, when you Take Steps for Cleaner Air Person opening window Improving air quality can reduce the number of germs in the air by increasing airflow, cleaning the air, or moving gatherings outdoors. Cleaner air can reduce the likelihood of spreading disease, particularly respiratory viruses. See CDC’s Ventilation in Buildings webpage for information on how to improve ventilation in a school.  Strategies that can be implemented to have cleaner air include:  Ensuring existing HVAC systems are providing the minimum outdoor air ventilation requirement in accordance with ventilation design codes. Considering ...
take the same hospital and put in place universal masking? Infection rates go down.

And this is part and parcel of what the CDC recommends for all of our hospitals.

But not for our schools, WHICH HAVE WORSE VENTILATION.

(Vaccinations also on this page...good ).
Let's jump to the actual page with masks. Sorry, the Additional Strategies page.

Mandates are not mentioned. Despite that being one of the CORE lessons we have all learned is crucial.

Back when Biden first began to demask America?

cdc.gov/orr/school-pre…
Image
Masks had 84% or so support. But 84% of America sure wasn't masking.

👇 Masks recommended - as only an antimasker could recommend them.

Kids don't wear N95s in general. So, next best- KN95s? The counterfeited KN95s from Amazon?

You would think the CDC would mention KF94s, Cloth masks generally offer lower levels of protection to wearers, surgical/disposable masks usually offer more protection, international filtering facepiece respirators (like KN95 respirators) offer even more, and the most protective respirators are NIOSH Approved® filtering facepiece respirators (like N95® respirators).
from Korea with their much better regulatory process.

And most of all ? Why not mention elastomeric respirators for kids?

DISPOSABLE RESPIRATORS (N95, KF94, KN95) LOSE FIT!

Sure, @flo_mask is the best game in town for elastos in town, but at least mention the genre.
I assume someone from the @CDCgov reads the NYTimes?

The CDC goes on to recommend possibly adding masking to anti-bullying programs - acknowledging the issue with not having mask mandates. While not mentioning the word.

And a bit later, they point out that immunocompromised children should not be segregated...while ignoring the
Image
Image
fact that not having all in masks? Segregates those in masks.

These CDC guidelines are a touch better than what they had before, but it not only continues to hurt the kids? But the CDC and public health.

/Continued... Image
Which brings us to maximizing school attendance.

THE NEW CDC GUIDELINES WILL NOT MAXIMIZE ATTENDANCE, and hurt the public's view of the CDC.

That's right - the CDC is hurting public health. Hurting themselves. Hurting the kids. Hurting America.

With this guidance.

/Cont Image
I will say /fin when done.

Will infectious disease transmission be reduced by the new guidance?

Well, they already had handwashing, cleaning, sanitizing, formally before.

Ventilation was already there before, informally, thanks to Covid.

And infectious disease transmission
has only gone up since the end of public health emergency.

RSV, influenza, etc.

The Zeitgeist has Americans feeling constantly infected. Reddit, Facebook, x/Twitter, etc .

And this new guidance was already in place.

Let's take a simple example, "Jack and Diane".
They see the CDC guidelines. They think, "Yay! The CDC is stepping in to help keep Burt and Ernie from being sick nonstop."

But Burt and Ernie keep getting infected because nothing amhas actually changed since the end of the PHE.

Will Jack and Diane look favorably upon
public health? Or are they more likely to think, "Hey - maybe it IS the vaccines making our kids sick."

Because they already knew their kids school HVAC had been improved.

It is truly ironic that the CDC continues to hurt public health.

While trying to help public health.
I almost forgot to close out on the maximize attendance point.

The CDC is "trying" to maximize attendance. This ostensibly is to be done by preventing the spread of the flu, norovirus, strep throat.

Interestingly, covid not mentioned there.

And even more interesting?
Image
Image
All of those are airborne. But as Covid has shown, near field aerosol dominates transmission of airborne diseases.

The CDC is putting fomite and far field aerosol strategies at play.

MASKING is the THE near field aerosol NPI, and is shoved into the back of the closet.
(Note: far field improvements will result in small improvements in near field. Distancing as listed in Alternative strategies is also a near field aerosol NPI)
By ignoring the PRIMARY form of transmission in their HIGHLIGHTED NPIs?

The CDC WILL NOT MAXIMIZE ATTENDANCE.

COVID is as transmissible as measles?!

"BUT, BUT, measles can infect up to 90% of people they are in contact with!"

So can COVID.

Time to wake up. The lecturer tried to promote sales of a flax oil product, and many elderly people were lured to attend by the promise of free eggs, Xinhua News Agency reported.  He gave three lectures on Jan 10 and 11 in a Tonghua classroom while not wearing a mask, with each lecture lasting about 2.5 hours. A total of 97 people, most of them retirees, attended the lectures in a classroom whose doors and windows were closed, the China CDC report said. The lecturer went to a pharmacy at noon on Jan 10 due to muscle pain and other symptoms, indicating he was likely at an early stage of the disease then, it ...
So, some will be pushing back - always welcome, albeit this is anticipated.

Rnaught is just an estimate.

But the R0 of 6-8 has the most estimates.

Remember THAT scene from Outbreak with Dustin Hoffman - "It's Airborne." ?

SARS-COV-2 is airborne via HVAC. Just like TB is - but it is way more contagious.

Still no panic, right? We know how to be safe.

Motel 6, or AirBNB - no shared HVAC, is best.

But HOW do we know?

🧵
A recent study in South Africa used Syrian Hamsters to duplicate the study that finally convinced everyone that TB was airborne.

The TB study is interesting because the military vets in VA hospitals were getting infected disproportionately.

So, they used HVAC ducting to In 1956, tuberculosis was a major global killer, and it disproportionately affected military veterans hospitalized in the Veterans Administration hospital system. Then, as now with COVID-19, epidemiologists held that tuberculosis and other respiratory diseases were spread by large infected droplets through person-to-person contact or contaminated surfaces. But Richard L. Riley, an expert on lung physiology at the then Johns Hopkins School of Hygiene and Public Health, and his mentor, William F. Wells, had identified another possible mode of transmission.
connect a 6 room TB ward to 150 guinea pigs.

Of those 150, only 3 PER MONTH got infected.

Illustrating that TRANSMISSIBILITY is just a CLUE to if something is airborne.

Dr. Riley went on to patent UVC tech, and develop the Wells-Riley equation which is so important in airborne Atop the Baltimore VA Hospital, they constructed an air-tight closed ventilation system that connected a six-room tuberculosis ward to an exposure chamber with 150 guinea pigs. (Among rodent animal models, only guinea pigs could cough and sneeze, making them ideal for studying how respiratory diseases spread.) The guinea pigs were exposed to the infected air over a four-year period. A second group of 150 guinea pigs acted as controls: their air ducts were irradiated with UV-C lamps to kill TB bacilli.
In the test group, an average of three guinea pigs per month contracted TB, while no controls were infected. The experiment not only proved the airborne disease transmission of tuberculosis for the first time, but also quantified how many TB infections could be expected to result from exposure to a given number of patients over a defined interval.
The insights from the Baltimore VA Hospital studies were later used to develop the Wells-Riley equation, which quantifies infection risk and informs strategies to ensure staff and patient safety in contagious clinical environments. The model can also calculate the risks of transmission for airborne infections on planes and trains, in prisons, and in other public and institutional spaces.  As chair of the Department of Environmental Medicine from 1960 to 1977, Riley warned that the danger of infection from airborne diseases was increasing as people spent more time indoors and air conditionin...

Plaque, Stephan's Curve (Imperative) mixed with breakfasts that you can brush immediately after.

It's actually best if you brush immediately up on waking up. This gets the overnight plaque.

It starts forming 4-6 hours after you sleep - your saliva is 20 millititers/hr Dental Plaque on the bristles of a used toothbrush.  Yep, that came out of your mouth.
- during the day. At night? Just 3-6 ml.

Saliva washes away the bacteria, it contains bicarbonate, phosphate, and protein buffers that neutralize the acids being pooped out by the bacteria.

It also has the below ingredients. Who knew saliva was so cool?!

Or plaque? Antimicrobial Components  Lysozyme: breaks down bacterial cell walls.  Lactoferrin: binds iron, starving bacteria.  Peroxidases: inhibit bacterial metabolism.  Immunoglobulin A (IgA): prevents bacterial adhesion to teeth.
Plauque forming bacteria.
By brushing first thing, fluoridating, and then waiting a 1/2 hour before eating, you just prepped your teeth for their Acid Trip through the day.

Like if you like salsa on your breakfast burrito like I do.

But what is a good breakfast if you have NO TIME to wait for the 60 tripping the light fantastic.

Ah, it's that time of year again. The pitter patter of children's feet. The laughter of high school students as they flirt with each other.

The coughs of their parents.

Is a Portable Air Cleaner (PAC) on a desk aimed at the wee ones' faces going to protect them? Spicoli from Fast Times at Ridgemont High with a Levoit Air Cleaner pointing at his face braced up with a weight.  In the middle of his pizza.  Not cool, man, not cool.
TLDR? No. They need to be in a N95 or KF94 purchased from legit distributors, not from Amazon, and eat their food outdoors, spaced far enough away from their friends so as not get infected. Or use @sipmask and protein shakes at lunch in the cafetaria.

You need to teach them
about how it can take as little as one breath of uncleaned-air to get infected (100 virions study on my profile). How it can mess them up in terms of their entire body.

You need to have the "Birds and the Bees and Covid" talk, in other words.

But will a PAC aimed at their

Calley is lying from the very first sentence. The media is not cheering for MAHA to fail. They are cheering for antivaxxers to fail.

We all want to see better food, less chemicals.

But we are not idiots.

The single largest gain in American life expectancy was
between 1900 and 1940, primarily because of improved water & sewer sanitation. Adding 16 years of life expectancy.

And vaccines are a close second - adding 5-10 years a bit later - in the last half of the century.

If we get rid of vaccines? We lose 5 to 26 years, depending
if we lose smallpox and diptheria.

There's another thing. Calley wants us working on the below things.

The Red Arrows point to things that will not mean a thing because of the next tweet. Image
