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 ... weekly.chinacdc.cn/en/article/doi…

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.

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.

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

People often underestimate the power of having someone with the reputation of Wolfgang Leitner, weighing in.

This is truly a significant development.

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

Microplastics.

In your testicles. Or your ovaries. Your brain and other organs.

But where do they come from? Are you eating, drinking, or breathing them in?

3 biggest fixes you can do? Get a water filter that handles PFAs - it will also do Image also handle microplastics easily. Next, rinse off your vegetable and fruit with that filtered water.

When driving around in your car? Have a little HEPA running. @cleanairstars is a great resource. @ThisHouseFresh has a handy RV HEPA review article.

Someone in the 7 Oaks School of Ontario IPC, like @zchagla, @DocDominik, @HotaSusy, @BogochIsaac @skepticalIDdoc has gone anonymous.

Remember - that group personally signed affidavits saying surgical masks are good enough to de-N95 nurses, who went on to die .... At greater numbers than the population.

Who were sentenced to lives of LongCovid.

It all started in March of 2020, when the 7 Oaks School of Ontario IPC signed a nasty, but quiet, little petition to deny airborne precautions. Image

In the next pandemic, these "RCT or STFU" worshippers plan on sacrificing you on the alter of RCTs.

This is Dr. Atle Fretheim 👇 talking about how they attempted to get masks randomized from his government.

And thankfully, shot down.

They are working on getting pre-approval from the WHO for what is called their "Master Protocols 👇," to then help smooth the way with their local government.

AVERAGE CO2 in the dead space below an N95? 1-3% - or 10,000 to 30,000 ppm. Scary?

No. You see that's the average.

Humans have focused on average or peak exhalations/waveforms.

We haven't studied the LOW POINT with capnography.

We have done it with simulations. Image
There are no published experimental (human) capnography studies inside N95 dead space that show the CO₂ dropping down as low as ~0.4% within a single exhalation. Human trials typically measure peak or average values rather than full breath waveforms. As you can see, the amount of CO2 in the N95 goes down.

Why? Because the air around us has so much less CO2. When we inhale, it mixes with that high CO2.

Dilution and diffusion both at play.

How NOT to Science. A time travel thread and magic.

This is Helmut Traindl - the engineer who devised the procedure behind Walach CO2 study that was retracted after 16 days:
jamanetwork.com/journals/jamap…

Then, republished by Dr. Domingo just 6 months later.
sciencedirect.com/science/articl… Image @RetractionWatch had an interesting write-up on how it was republished by Dr. Domingo.

It rings of plausible deniability. Except it smells vaguely of bad faith.

So, in your apartment or hotel, we saw below how its heated facade, or front, could drive your downstairs neighbor cough into your lungs.

Let's step inside your living room now, and step forward in time to winter.

What happens if your sick neighbor is seated in that living /1 room?

Where is the worst place for them to be seated if you have your heat coming from a heat register up on the wall?

Next to your cold window.

The cold air cools your sick neighbor's exhaled infectious air, and drives it to the ground.

I looked at your thread @moog77 . The reason that epidemiological didn't work (cases continued to go up)? Is the same reason the 2023 Cochrane fails, ironically, after you touted it as the "gold standard."

Not because clean air doesn't reduce cases. It empirically does. It just doesn't do it where it's not being applied.

What do I mean?

2023 Cochrane "the gold standard" - for community masking is based on a few studies.

One is Alfelali (2020) set in the Haji season

Do you live in an apartment or stay in hotels?

Got a "oops, outside air can get you" study. Coming out of Beijing University of Technology - taking airborne transmission seriously.

They rented 50 rooms of a building. Did some very cool CFD work - then, be still my heart, Image followed it up with tracer gas experimentation.

See room 303 above? 403 and 503 got whatever came out of 303.

With studies like these, there are so many variables. But, if I lived in an apartment, I would set have at least a PC fan CR Box next to those open windows.

Swimming and showering.

Below is the thread of collected "swimming/ showering safer in indoor shared air" solutions, so far.

You might be thinking that the chlorine smell protects you near the pool. Chlorox is great.

But you would be thinking incorrectly.

Thread. Filti media wrapped out an inside brace made out of zip ties. Laugh all you want, but it works, yo. Have there been indoor swimming pool transmission events? Yes.

And more.

Were they in the swimming pool or in the more likely shower/ locker rooms or lobby? Nobody has teased that out.

I am deep in NCL3 studies as someone pushed back on swimming pool transmission-and I take my disease transmission prevention very seriously.

Wait - what? NCL3? Image NCL3 is trichloramine. That actually maybe most of what you are smelling in the pool.

Hold onto this golden nugget - swimmer's sweat and body oil ALSO results in trichloramine.

DO NOT THINK about the urea (ahem, urine).

As a lap swimmer, I did NOT know that. Image

So, I got curious.

Despite the pore sizes of the N95 filtration being so much larger than CO2 molecules, there is a greater concentration of CO2 in the N95, than outside.

Why?

We exhale 4–5% CO2 (40,000–50,000 ppm), much higher than the ~0.04% (400 ppm) in ambient air. Image What is the the AVERAGE CO2 in the dead space below an N95? 1-3% - or 10,000 to 30,000 ppm.

Sounds scary high, right? It's the AVERAGE. Below you can see it rise and fall. See how at the end of the inhalation it's almost zero?

But what happens to that CO2? We inhaled it Image

Are you reading this thread because you said you were worried about CO2 in an N95?

Hypercapnia?

1. Don't worry - be happy. This thread explains why you should not be worried about those things.

2. If still worried? We'll get to what YOU can do about it. In 1998, long before the mask controversy of 2020, the OSHA Respiratory Protection Standard was passed.

Tired: Infectious fecal and respiratory aerosols.
Wired: Infectious urine aerosols.

Do you know how many aerosols you generate at the urinal, standing up?

Do you know how many aerosols you generate on the toilet, sitting down?

Do you know you have a thermal plume lifting both up to your breathing zone?

Do you know that you can get an N95 at Home Depot or Lowes - and you can wear it into their public restrooms?

Studies to come to avoid the Musk Masking algorithm.
