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.

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...

I am sorry if this will upset you. A lot of people depend on NASAL SPRAYS for C0V1D.

I have been iffy on them, but viewed them as "if they don't hurt, why not" but not for me.

There's an analysis
on Reddit that you should read in detail, and make up your own mind.
/1
Here is the link:


Here is a 4 tweet TLDR version.

Here is how it starts - the author goes HARD at the underlying studies. reddit.com/r/ZeroCovidCom…There is no convincing evidence that nasal sprays prevent COVID-19 There is a lot of misinformation out there about nasal sprays preventing COVID-19. Unfortunately, there are no convincing studies showing that nasal sprays prevent COVID-19. The published studies investigating whether or not nasal sprays prevent COVID-19 each have major issues, which I will detail here. I have a PhD in biochemistry and one of my PhD projects was on COVID-19. The main takeaway of this post is that there is no sound evidence that nasal sprays prevent COVID-19. Thus, nasal sprays should not be used for COVID-...
Some pretty harsh language, but to me the important thing is we still have clean air.

Which is good, because it boils down to only 2 studies saying that nasal sprays work, per them. 5. Summary/TLDR and final thoughts Unfortunately, many people including covid influencers have fallen for the grift of nasal sprays preventing COVID-19. Some such influencers have promoted these nasal sprays for free and helped spread the misinformation that they prevent COVID-19. Unlike with nasal sprays, there is ample, sound evidence that high-quality well-fitting respirators, ventilation and air purification prevent COVID-19. The human clinical trials testing whether or not nasal sprays prevent COVID-19 are garbage, and to my knowledge there are only two! Please don't lower your covid...

Guillain-Barre Syndrome linked to poultry eggs? H5N1?!

The BBC had a good article from February 3 that talks about how these Indian states' cases are linked to campylobacter jejuni, a bacteria. It IS the most common root-cause, globally.

And IT is commonly found in poultry. AVOID CHICKEN AND EGGS RIGHT NOW SIGN showing for the country of India in a tweet from @alwaysmadesh. Due to Guillain-Barre Syndrome.
"Campylobacter jejuni infection is the common associated microorganism (25–40%), followed by cytomegalovirus (6–15%), Mycoplasma pneumoniae (3–21%), and Haemophilus influenzae (1–9%)"

BTW - Cytomegalovirus is also an airborne virus - that just happens to cause brain cancer.
Mycoplasma pneumoniae - also airborne.

And...drum roll please...Campylobacter jejuni also airborne.

Don't get me wrong - jejuni most definitely is also fecal-oral, no question.

But it's also airborne.

Sampled from the air below. Figure 7. GCN/m3 results using microorganism-specific primers. These microorganisms were chosen for their pathogenic and opportunistic nature. Samples 1–12 indicate the WWC collections in House A, 1R–12R the WWC collections in House B and 1F–12F the filter collections in House A.

Just a little bit closer to acknowledging H5N1 is airborne.

3 vets asymptomatic, + for bird flu antibodies. Did not wear respiratory gear or glasses.

Did wear gloves and coveralls - so rules out fomites.

One practicing in states with NO H5N1.

Vets get very close to /1 No seropositive practitioner knew that they were working with dairy cattle with known or suspected HPAI A(H5) infection. None of the seropositive practitioners reported wearing respiratory or eye protection while providing veterinary care to cattle. Neither respiratory or eye protection is recommended when working with uninfected animals in regions without confirmed cases; however, safety goggles and a respirator are recommended when working with uninfected animals in regions where there are confirmed or potentially infected animals (4).
Among 150 bovine veterinary practitioners, three had evidence of recent infection with HPAI A(H5) virus, including one who only practiced in two states (Georgia and South Carolina) with no known HPAI A(H5) virus infection in cattle and no reported human cases (1,2); this practitioner reported no exposures to animals with known or suspected HPAI A(H5) virus infections. These findings suggest that there might be HPAI A(H5) virus–infected dairy cattle in states where infection in dairy cattle has not yet been identified, highlighting the importance of rapid identification of infected dairy cat...
aerosol sources. Aerosol orifices.

This lines up with previous studies.

Reported use of N95 FFRs or other respirators and other types of masks was low (9% and 27%, respectively) among workers exposed to ill cows the week before A(H5N1) outbreaks were d...

Veterinarians are one possible vector between infected and uninfected herds/ farms.

Latest Pew Poll.

Or an exercise on "How well did Biden disappear C0V1D?"

On one hand, 21% of Americans still view C0V1D as a major public threat 21% of Americans still view COVID as a major public threat.
On the other hand, still masking?

6% of Democrats
4% Americans
2% Republicans

Guess when Biden took over on the graph? On the other hand, still masking? 6% of Democrats 4% Americans 2% Republicans Guess when Biden took over on the graph?
Yes - pretty much as soon as Biden took over, he began disappearing C0V1D.

BTW, the last poll was by yougov - masking was at 12% last year. On the other hand, still masking? 6% of Democrats 4% Americans 2% Republicans Guess when Biden took over on the graph?

What do we need to do to make every healthcare worker in the world understand that flu is airborne?

Get IPC on board.

Let me introduce you to Dr. Zahir Hirji, President of @IPACCanada at #IPAC2023.

Where do we know him from?

That's a very interesting question.

/1 Image
In 2006, Dr. Tellier wrote an article in the CDC EID explaining that influenza was airborne via aerosols.

Quite nicely done.

pmc.ncbi.nlm.nih.gov/articles/PMC33…
Dr. Zahir Hirji and some other IPC doctors from the Canadian HUGE University Health Network disagreed.

Right back you, Tellier - in 2007.
