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.

Doctors and nurses get infected in their own hospitals unfortunately.

But there is one hospital in America that has had zero of these infections in over 25 years.

Not one single doctor or nurse in that hospital has been infected.

Not one.
Would you believe that it's a hospital dedicated to an airborne disease, tuberculosis?

The Texas Center for Infectious Diseases, while not a large hospital, does have 170 employees.

In 1996, they gave everyone reusable N100 elastomeric respirators.

elemental.medium.com/a-tiny-hospita…
Since then, no Hospital Acquired Infections. And - they saved a ton of money by using them instead of N95's.

Here's a true CoVid story from the Chicoutimi Hospital in Quebec, Canada. From catastrophe to redemption.

Huge outbreak of 400 employees over 2.5 months, directly linked to nosocomial infections. 70 HAI patients.
To be frank, at first the employees were blamed.

Because of overtime due to CoVid - but the employees were blamed.

lequotidien.com/actualites/dur…

Was that the end of the story?
No. The workers did not want to catch CoVid. They were careful.

See the quote below from Anne who caught CoVid below.

And the outbreak continued, until someone decided to test the ventilation.

Dekalb County in Georgia- dozens of school bus drivers on strike to get more enforcement of kids wearing masks, notice of a CoVid+ kid (!?), And plexiglass.

wsbtv.com/news/local/dek…
@TyishaWSB - can you get word to the bus drivers that plexiglass is not the solution, since CoVid is airborne? (Like smoke).

This is Dr. Linsey Marr, respiratory virus transmission specialist and aerosol scientist.



But what will work?

Here's a true CoVid story from old Victoria. From catastrophe to redemption.

Victoria, Australia, that is.

"In the second wave, Victoria was by far the hardest-hit state. Its case numbers were dwarfing those in every other state..."

On August 11, 2020, the government said that max 15% of HCW infections were acquired at work.

Then, on August 25, 2020, the government reported that figure was actually 69%.

@Tim_Heffernan @wirecutter

Hi Tim,

Your information on OPE, or source control, below is incorrect

NIOSH has found that respirators with exhalation valves do provide surgical mask level control.

Article:
healthleadersmedia.com/covid-19/niosh…
Study that the article is based on.

cdc.gov/niosh/docs/202…

Regarding IPE, inward protection, NIOSH has already found that is not a concern.

Here is a Webinar where they cover these subjects.

You should be urging everyone to be in an N95 or better.

In fact, I'd like to invite you to join our campaign, #BetterMasks4All, or:

"N100 to STOP COVID in 100*!"

*100 days.

I have more information on that if interested.

In the meantime, I beg of you to change that story.

You are correct!

Man - this virus is really taking down some high-level antivaxxers and antimaskers.

Can we call those who oppose both, antimaxxers?
