We, all, are the #corsirosenthalbox community come to life.

We all share the common interest of having clean lungs - and not catching CoVid.

This is a 🧵of homes in which one person unfortunately brought CoVid back.

But homes where no one else caught it. Image
Please @ me if I didn't catch your story when I was meandering the halls of Twitter, and you want to be in this 🧵.

As @JimRosenthal4 always says, and I have seen @CorsIAQ agree with.

"We are not helpless!"

Your story:
Have some more waiting confirmation on.

In the meantime, thank you to Mike for the beautiful build!

@faroop the cleanaircrew web site we urge wearing an N95.
Transparency is key!

2nd tweet down:
If you came here because someone tested positive.
Do NOT give up hope!

In home transmission rate is higher than before but still around 33%.

Immediately, everyone put on N95's, crack those windows at least an inch, and get the sick person by themselves in a room.
Then read these:
Isolation room:


$900 Air Cleaning for $100 Long thread - may want to jump to ...next couple of links.


The FAQ has same info, but cleanly laid out:

Another "CoVid snuck in the back door, but no one else caught it" addition!

(These take time as I need confirmation and permission to add. If you have a story? Do a tweet, and then retweet it @ me ! )

Another "CoVid snuck in the back door, but no one else caught it" addition!

Probably the most high-profile addition to the "CoVid snuck in the back door, but no one else caught it" 🧵.

Folks, we are NOT helpless!

(He confirms no spread later in the thread).

Someone came home with CoVid? These 🧵's are for you.

You are not helpless - and not alone.

Another shared excellent thread of someone who had someone bring home CoVid - and everyone else stayed safe:

Got a friend who tested positive and has loved ones at home?

Lend them yours! And build an extra one for yourself!

(Way to go, Kevin!)

Need to talk a principal or a boss into bringing in a #CorsiRosenthalBox ?

cleanaircrew.org/boxfanfilterfa…
Another report of "CoVid came home as an unwanted guest - and got the boot after infecting no one else."

This is the 18th family that has had CoVid show up as an unwanted houseguest - and no one else caught it.

Due in part to the #corsirosenthalbox.

Number 19!

20th story of success using a #CorsiRosenthalBox and a variety of other interventions to kick CoVid back out the door after it comes calling.

Even when it's BA2 or Omicron.

We are NOT HELPLESS!

21st story of success using a #CorsiRosenthalBox

YOU are NOT HELPLESS!

(TLDR?
Family of 4. Vaccinated, boosted, ventilation, CR boxes, masks, and tests. )


Image
22nd story of #corairosenthalbox of success!

23rd story of #corsirosenthalbox success!

To quote Jim Rosenthal, "We are not helpless!"

See a tweet of a family exiting with no further transmission? Tag me!

24th story of Covid coming calling with one person in the house - and leaving empty-handed.

25th story of Covid coming calling with one person in the house - and leaving empty-handed.


Image
26th personal story of success with keeping Covid at bay, despite its attempt to get the whole family.

Always remember - respirators, ventilation, filtration, and a fired-up will to win.

We are not helpless!



Image
Image
27th story of #corsirosenthalbox (and other clean air tech like N95s) success, keeping CoVid at bay - despite infecting family members.

H/t @joeyfox85 and @PettersenKenny !

If you are reading this, worried about CoVid spreading in your home, brought home by a loved one?

Don't be.

This is the 28th story of success of using the #corsirosenthalbox to keep CoVid from spreading in the family.

In this case, also used were.....

""N95 (or P100) mask when entering the isolation area. Isolation area had its own small kitchen so entering wasn't needed frequently. Home tests (BinaxNow if I recall correctly) were used to determine end of isolation." Image
WE ARE NOT HELPLESS!

29 families who had Covid sneak in with one loved one....and there it stayed.

No one else got it.

These are their words. Their "how-to's" - written to help YOU!

More details on the 29th.

The 30th story of #corsirosenthalbox success!

As always, it's not just the box, but N95s, etc, all working together to keep you inhaling clean air. Image
And as always - their story in their words!
31st successful story of the #CorsiRosenthalBox protecting the rest of the family after one member came home positive.

This one is longer - but the careful thought into where the air flows in the home makes it worth it!

A doctor complaining about wearing N95s? Thread foreshadow in the gif 👇.

Dr. Sax, you should read this.

The arrogance of medical doctors thinking they know better than the CDC NIOSH and OSHA?

This comes as no surprise.
Imagine if an asbestos worker, or a tech working in BioSafety Lab was complaining about this.

But somehow, doctors making over $200,000 get carte blanche and and a piece in the @NEJM Voices.

And he does have a loud voice.
This is Dr. Sax, Clinical Director, Division of Infectious Diseases (ID), at THE Harvard hospital. In 2014, he wrote about how ID docs only make $174,000.

He probably makes northwards of $269,000.

This is very, very relevant.

You see, he is put out by the inconvenience Image

From the ZeroCovid sub on Reddit.

How DO we do it?

Hyper vigilance, constant exposure calculations, discussing and taking precautions?

How do I do it?

Quick thread. I would like to hear covid conscious folks opinions on this: I have long covid (mecfs + pots + mcas). I’ve been sick to varying degrees since 2022. My life has been severely affected by this. At this point, I can’t work. I am mostly housebound, recovering slowly but I still have to spend some days in bed. Recovery from this is awful, especially because it’s not widely understood. With all that said. I still feel like, for me, a life full of hyper vigilance, constant exposure calculations, discussing and taking precautions…I can’t do it. I don’t want to live that way. How can I approach t...
I don't do it.

I don't do exposure calculations.

I don't have hyper vigilance.

I am Vax, Mask, and Relax.

For me, it's just a series of habits now. Drive to the wherever, hit parking lot, put on N95. Get out of car. Stays on until I get back into the car.
A new vaccine comes out? I get it.

I go stay in a hotel?

2nd floor Motel 6 with no shared HVAC (has the PTAC) . Open door/windows for one hour until complete air exchange.

Go through a drive through? N95 on before window is rolled down. Drive away? I roll down both to

After reading a study, and reaching for my phone, if the first thing I do is check to see if I have @'d someone in the past?

That's not a good sign.

I have never @'d them, and this is not directed @ them.

But this IS a debunk thread.

And it starts with who.

Study here. Before you read it?

This thread is about providing context. Read the thread, @SalvMattera's comments, AND THEN, read the study.

0/10 from me.

thelancet.com/journals/lanep…
Who paid for it? The Dutch government - who has been spectacularly almost Tegnell-like in their downplaying of LongCovid and masks.

Lead authors are from RIVM, their CDC.

RIVM was antimask even when they FINALLY recommended masks in OCTOBER 2020.

Oh, we are cooked. Just cooked.

"Brain Mitochondrial dysfunction, known for ~20 years is finally recognized as a central upstream driver of Alzheimer’s disease (AD), not just a downstream effect."

And SARS2's targeting of mitochondria is well-known.

Even in the brain.
/1 We identified dysregulation of mitochondrial and synaptic pathways in deep-layer excitatory neurons and upregulation of neuroinflammation in glia, consistent across both mRNA and protein. Remarkably, these alterations overlapped substantially with changes in age-related neurodegenerative diseases, including Parkinson’s disease and Alzheimer’s disease. Our work, combining multiple experimental and analytical methods, demonstrates the brain-wide impact of severe acute/subacute COVID-19, involving both cortical and subcortical regions, shedding light on potential therapeutic targets within pat...

@neiljshaw - — a few tips on your excellent article from a clean air advocate

"Consider Wearing a Mask" ?

No, "It is incredibly important to wear a well-fitting mask such as a N95, KN95, or KF94, for the best protection."

You two are doing Image
public health with this article.

Public health is best done with simple clear instructions.

No:
"These masks act as a barrier, reducing the spread of respiratory droplets when people talk, sneeze or cough."

Yes:
"These masks act as a HEPA air cleaner for the face,
cleaning the air of respiratory aerosols when people breathe, talk, sneeze or cough."

The barrier carries the idea of an immovable wall. Unable to be penetrated by things like oxygen and CO2 - which feeds antimaskers.

As an who debunks antimaskers, it is

As an anonymous clean air advocate, I've put a bit of thought into how to present, well, my expertise.

If someone were to say, "How do I know you know what you are talking about? Are you a doctor, or a virologist?"

To which, I would say...."No, but that's a good thing.

I have focused on aerosol and masking science. Because it is those fields that give us the most information on how airborne particles, aerosols, get from Person A to Person B.

My expertise is derived from the great studies of Dr. Lindsay Marr, MacArthur recipient. Dr. Prather,
double National Academy member, Dr Milton, inventor of the Gesundheit, aerosol scientist and medical doctor; Dr Coleman whose group found that duckbill N95s captured 98% of emitted respiratory aerosols, and more excellent individual aerosol scientists.
