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.

Trump is trying to distract from the economy. He just pumped out the Lab Leak from the official whitehouse.gov website.

Simultaneously making masking advocacy both more difficult and easier.

The Shrodinger Presidency. If only he had.... /+

Of course I don't wish him dead in a box. That is against Twitter's TOS.

But, anyway, what do I mean? On the one hand, pointing out that Covid is probably a bioweapon means that you can point out the silliness of not protecting yourself against it.

On the other hand, this: Image
Which, of course, is silly as workers in BSL2-4 labs wear N95s and better to protect against bioweapons.

Heh. I can tell an antimasker wrote that because they screwed up the logic on it.

Mask mandates do NOT equate masks.

@TheAtlantic @danengber Heh - I suspect Mr. Engber has been eavesdropping on my (and my fellow Covid Conscious) swimming safer threads. I have a new solution for showering safer for that I will be rolling out tomorrow.

For future articles by those who will come along, let me point out a few things /+
@TheAtlantic @danengber Thank you very much for pointing out that 4% of America is still masking 100% of the time! That is 13.2 million Americans.

The Masking Nation is larger than 38 states. :)

But, 18% of us masking some of the time in the SAME PEW POLL (tch tch). You would think that would be/+ At a basic level, their COVID-conscious attitudes may not be so far from the mainstream. Twenty-one percent of Americans still think of the disease as “a major threat” to public health, according to a recent poll from Pew Research Center. Thirty-nine percent say we’re not “taking it seriously enough.” But if 50 million to 100 million adults harbor such concerns, very few are doing much about them. Masking rates were once as high as 88 percent; now they’re close to nil. For those who still maintain their masking habit—4 percent, says Pew—the whiplash in social norms has been a shock.
@TheAtlantic @danengber be mentioned, @TaylorLorenz, by Mr. Engber, since 18% lines up pretty closely to the 21% still worried that Covid is a big deal (it is) - that he mentioned.

And suddenly, Masking Nation has 59.4 million residents. We are the largest state. Canada /+

This may be one of the most important studies in a decade.

#LongCovidBinder.

"The models produced correctly classified those with severe ME/CFS from recovered controls with an accuracy of 97%, sensitivity of 94%, and specificity of 100%. "

THAT IS HUGE.
"We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. " We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. IL-5 enhances the production of B1 cells which are anti-inflammatory (impaired B1 cells have been found in multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis), and IL-13 has anti-inflammatory properties. Jason et al. [26] also found that students who failed to recover from IM had more restricted, inflexible cytokine networks whereas those who recovered had more flexible, less interconnected networks. Network analysis suggests that IL-5 and IL-13 influe...
So, this means ME/CFS can be predicted.

And what can be predicted - treatments can be found.

And they are studying LongCovid as well.

This study is easy to read, And everyone should.

A new study just showed what I have been saying since the start of bird flu. H5N1 is airborne.

Still in place?
USDA: YOU ONLY NEED TO TEST LACTATING COWS.

oops.

USDA: FOMITES (infectious objects) SPREAD IT.

oops.

WASHING YOUR HANDS WILL STOP IT.

oops. This new Federal Order does not override or supersede USDA's April 24 Federal Order, which still requires the mandatory testing of lactating dairy cows prior to interstate shipment and requires that all privately owned laboratories and state veterinarians report positive test results connected with those tests. The new Federal Order announced today is intended to complement and enhance this existing order.
Question [00:51:52] Given the CDC's vaccination program, I'm wondering if this means you think it's no longer realistic to expect that the outbreak will be contained this year? Eric Deeble, USDA [00:52:12] Just on the animal side and all that Dr. Nirav speak to the human side, there's a lot about this disease that makes us feel as if we can arrest its progress. And we've actually seen some success demonstrated to date. With this disease, it does not appear to move by respiratory transmission. We know that there are high viral loads in milk, and we've identified through close, collabora...
In addition to testing, biosecurity is the key to containing this virus, and ultimately ensuring that it is eradicated so that producers do not have to deal with this virus in dairy cattle permanently. Good biosecurity including cleaning and disinfection of vehicle and equipment - is critical to minimizing the risk of disease spread. USDA works closely with state animal health official, producers, and industry organizations to provide guidance and resources for cleaning and disinfection not only on affected farms but for all livestock producers as a part of practicing good biosecurity. APHI...
The study.

✅ 20% of the cows showed up as sick. Had symptoms. But....

✅ It turns out that 89.4% were actually infected.

✅ 83.7% of those had no symptoms. Remind you of any other airborne diseases?

✅ 40.5% of the dry cows not being milked? Infected. So, no Image

fomites or milk aerosols involved, most likely.

There is not much that scares me. Freaks me out.

I am freaking out.

You should be, too.

Do you know what this shows?

Do you know how to avoid this? Holy cow.
This is the continued accumulation of dementia-causing microplastics in your brain. Simple linear regression (shown with 95% CI represented by dashed lines) was performed for total plastics, polyethylene, polypropylene, polyvinyl chloride and styrene-butadiene rubber measured in normal decedent brains from 2004 (average of east coast samples), 2016 and 2024 (NM OMI samples).
See how it increased from 2016 to 2024?

And it actually is worse - they found less plastics in brains from a decade earlier.

Great interview of Ed Yong - I am just covering the C0V1D part.

/1 The Interview Ed Yong Wants to Show You the Hidden Reality of the World Ed standing with his arms folded. His eyes tell you COVID is not over.
You've been clear in saying that C0V1D has not gone away. You ask people to wear masks at your events..... You’ve been clear in saying that Covid has not gone away. You ask people to wear masks at your events. But that attitude is not necessarily where the rest of the world is. How do you think about continuing to take precautions and advising others to do so when it feels as if society has moved on? I do it for a bunch of reasons. Firstly, I have learned that I enjoy not being sick. I know that the cost of long Covid is real and substantial, and I don’t want to run that risk lightly.
"I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird." . I also know that I have many friends and people I’m close to who are immunocompromised. So for the sake of the people around me, I also don’t want to get sick. When I do events, I wear a mask for those reasons, and because I know that every time I do a talk, while the vast majority of people in the audience have probably moved on, there are going to be other people who haven’t. I think it makes a huge difference to them to have the person at the front of the stage wear a mask. It tells them, It’s not weird. So I do it for that reason, too. In terms of holding this line at a point when a l...
