Had the idea of fixing the contact tracing form.


But CDC isn't doing contact tracing - (thank you Ian!),


but their training feeds into the states, which feed the counties, etc))
Tried acccessing the website that all of the states/ local authorities use to develop their contact tracing forms:
cdcpartners.sharepoint.com/Sites/CSTLTS/C…

But it's locked down.

Poked around Washington State's website, and couldn't find any actual forms.
All good.

Let's a look at the CDC's contact tracing information (that feeds the states, etc), and see how it's letting us down.

cdc.gov/coronavirus/20… - literally says, "Contact Tracing slows the spread of CoVid-19"

Maybe. But since we are
literally the absolute worst at CoVid?

statista.com/statistics/110…

Clearly, we are not doing it, correctly.

So, what is our contact tracing based on?

Key information to collect during a case interview.
cdc.gov/coronavirus/20…

The most important part? Close Contacts.
And what is the definition of close contact?

Anyone within 6 feet for a cumulative of 15 minutes within 24 hours.

Except if they're a kid - and then they are excluded if 3 to 6 feet away and wearing a well-fitted mask.

Quick note - the kid exception is

cdc.gov/coronavirus/20…
really, really
Anyway, where does the close contact definition come from?

Per this:
cnn.com/2020/10/21/hea…

From this:
cdc.gov/mmwr/volumes/6…

Highlights:
July 28, 2020 - a prison guard had 22 brief encounters, for a total of 17 minutes with 6 prisoners.
July 29, 2020 - all 6 tested positive
The guard had 2 other contacts - those people did not test positive.
All interactions were on video.
The guard was in a microfiber cloth mask and goggles the entire time.

So, ocular infection in this case was eliminated.

Anyway - was he infected from repeated exposures?
Possibly, but not probably.

No, he was probably infected during only one of those interactions.

But is that the end of the story?

It shouldn't be.

Where, oh where, can we possibly find someone who could help us see if there's a better definition of close contact?
Would you believe - the CDC?

wwwnc.cdc.gov/eid/article/27…

People infected from 45 feet away, with Patient Zero actually facing away from those he/she infected.

Caught on video. Genomically confirmed.

So, that would seem to be good place for the @CDCDirector begin to change the
definition to:
"Shared space up to 45 feet away for any amount of time."

And then, we will be closer to actually having contact tracing slow down transmission.

Until then, we only have Contact Tracing Theater.

Enjoy the show - though I hope you enjoyed this thread more.

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
Then they signed those nasty little affidavits,with two fingers crossed I am presuming, in April of 2021.

Deliberately to demask the nurses. Image

Guess what?

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.
/+

Image
But they have figure out "this one weird trick!"

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.

This is not an idle thing. Atle specifically used air filtration 👇@kprather88 @jljcolorado, as his example of a desired subject to give half of the class clean air in the beginning of a pandemic.

When we are MOST trying to stop the spread!

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.
journals.plos.org/plosone/articl…Image
As all of us who has ever worn a mask/N95, which is most of the world, knows, we don't suffer the effects of inhaling 30,000 ppm all day.

Lets look at this a different way.

What if we were in a room with huge CO2? That's what antimaskers are implying is going on.

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.

retractionwatch.com/2022/08/01/one…Image
Turns out that @TecnATox was founded, and is directed by Dr. Domingo.

You'll be hearing from me, Dr. Domingo - and a rather lot more people, once I get done writing all of this up.

You see, I found the pilot video.

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.

Where it sidles along until Image
Image
you and your family's bodies' thermal plumes pick up that air, and lifts it up to your faces to be breathed in.

Or....to put this in another way....if you go to a coffee shop as I like to do, and you see someone coughing next to a cold window? Do not dawdle.

Leave.

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
