I never want to hear about valveless respirators again.

H/T @PPEtoheros.



Delta said they weren't accepting them.

And THEN the CDC came out against them.

Despite having 624 valved respirators recommended for HCW's on their website. salon.com/2020/08/22/cdc…

Image
Image
@Delta @AssistDelta - please get your lobbyists to get the @CDCgov @CDCDirector to undo their RIDICULOUS valved respirator stance.

You broke this. You fix it.

3M says, "Nope, valved respirators are not a problem." Image
NIOSH says, "Nope, valved respirators are not a problem." Image
OSHA says, "Nope, valved respirators are not a problem." Image
CDC says "Nope, not a problem," indirectly, by recommending 624 valved respirators in their database for AIRBORNE disease protection. Image
A wet mask is actually a more permeable mask, and less comfortable. Image
Thank you @FredClarkson and Jonathan Hutson for writing this story!
Someone will reply with this study:


@NIST - NIOSH does not use schlieren imaging as part of its testing for a reason.

Please have Staymates stop with this misinformation - and you stop as well.

Source control for valved respirators is equivalent to surgical masks.

Per the NIOSH.

Boarding planes with elastomeric respirators is intertwined with this valved thread.

Here is the policy, 1st pic👇


The key sentence:
"Masks containing slits, exhalation valves, or punctures"

The order itself, 2nd pic👇

A GVS - the valveless GVS and valved look identical.

Which did not sound fun....
What to do to fly safe?

You are not going to get a chance to argue. Grumpy TSA & gate agents? Not worth the no-fly list.

Some strategies.

1️⃣ A valveless elastomeric respirator w/excellent protection that looks like a mask.

I just bought 4, including 1 for Mom - haven't
got it yet, but have done my usual ridiculous amount of research.

- these last for months, so I'd get black.

2️⃣ Already have an elasto? Wear a surgical mask over it.

📌Always bring a fold flat respirator with no valve tucked into your carry-on,prescientx.com/nano-mask
whether you do 1 or 2.

I like these:



Tested very well with masknerd.

And @projectn95 is guaranteed authentic.

Another winner:
@armbrust_usa's


✅ Great breathability.
✅ Individually wrapped - great for traveling.shop.projectn95.org/demetech-dtn95…

Thread of debunking the myth that "babies should not be masked."

A baby uninfected is better than a baby infected.

If you oppose masking babies, you are immediately for infecting babies.

Let's get to it. A most excellent instruction page on how to mask babies. Suck it antimaskers.
This solves an equity problem.

Not everyone has the money or technical skill to build a baby buggy PAPR.

Just like not everyone has the money to buy an adult PAPR.

Are you for people on SNAP being able to protect their babies? Or not?

Most can rustle up the money to buy some uber cute baby masks!

This is the link from the baby zine.

These need to be fit tested.

Now, let's get into the good stuff. The "OMG Laz has gone too far! We've got him!"

You better bring your A game.

If you are Covid Aware you have probably been avoiding the dentist. Well, the dental studies have come to you.

This edition? #CovidAwareSoReducingDentalVisits - Water flossing (WF) edition.

Or, as I like to think of it, the Gum Salon.

Thread.
Flossing is necessary for those super tight contact points as you see in the above thread, and is great to remove plaque down 1 mm deep in the gum line (gently).

InterDental Brushes are fantastic and go down 2-3 mm into the gum line to remove plaque.

And WFs in general, are, well, amazing!!

They basically go back and forth with InterDental Brushes on which is better as far as being the top of the food chain for overall cleaning of the space between your teeth.

But.

If you have gum recession, you may have this Image

#CovidAwareSoReducingDentalVisits - less mouth open = less 'vid risk.

I am a GREAT flosser. My family thought we had genetic gum disease.

Below we can see rubber stick on the left, floss on the right, and a InterDental Brush (IDB) in the middle.

See the problem?
/1 Image
A couple more example pics on why I am sick to my stomach thinking of all that money wasted.

We THOUGHT we had great dentists. Not a single one mentioned IDBs, and how the bristles allow all interdental spaces to be reached.

And it gets better!

/2 Image
Image
IDBs actually reach down in between the gum and teeth - 2-3 mm. Floss? Only 1-2 mm.

As plaque grows down into and touches your gums, that's what causes them to get inflamed - and begin to retreat (very simplified).

If you brush that space? Problem solved.

/3 Floss, Interdental Brushes, and Waterpics Use all of them - floss works great for those narrow spaces. Interdental Brushes (IDB) work great in larger spaces. Waterpics work great immediately after eating, as you want to wait for an hour eating acidic/sweet just like regular brushing. It is a mistake to NOT IDB. Multiple studies indicate IDB is good, including this RCT where IDB was better than flossing (free version - great how to brush) - with people with chronic periodontitis. Students found IDB to be better. But IDB is better than rubber picks is better than floss. IDB way better ...

Covid Aware Teeth

The Calcium Lactate Rinse. Cheap, super easy to do - and it really enhances your fluoride uptake to re-enamel your enamel.

It's just not very well known, despite being very well supported within studies - and very cheap.

Mix 1/8 tsp with 1 oz water. Shake
thoroughly, till the granules disappear. Takes a few or 20 shakes, then just wait. Rinse for 1 minute. Spit out.

Immediately brush with fluoride or fluoride rinse.

There might be a better powder

I use the same 1 oz shaker as my stannous fluoride rinse comes in.

(That fluoride rinse was $4 cheaper at my dentist than this $24.

My Prevident 5000 ppm actually did not need a prescription - if bought from my dentist, as a couple of side notes.)

.On the one hand, we have study after study showing 36% or so rate of LongCovid.

On the other, we have the WHO saying the rate of LongCovid is only 6%.

I got curious. What drugs are the WHO smoking - and can I get some?

🧵. Image
My 36% comes from the latest massive meta:
eatg.org/hiv-news/more-…

But what about that 6%?

Turns out it's this old chestnut from 2022.

And there are such major players on it...so many I can't even screenshot them all.

But I fear no title - and neither

jamanetwork.com/journals/jama/… Image
will you.

The problem with this 6%? There are 200+ symptoms in the LongCovid symptoms constellation.

This study focuses on three clusters.

Which is incredibly vague, which is normal for the WHO.

So, after digging through the f***ing supplement, there are a few symptoms Image

COVID is as transmissible as measles?!

"BUT, BUT, measles can infect up to 90% of people they are in contact with!"

So can COVID.

Time to wake up. The lecturer tried to promote sales of a flax oil product, and many elderly people were lured to attend by the promise of free eggs, Xinhua News Agency reported. He gave three lectures on Jan 10 and 11 in a Tonghua classroom while not wearing a mask, with each lecture lasting about 2.5 hours. A total of 97 people, most of them retirees, attended the lectures in a classroom whose doors and windows were closed, the China CDC report said. The lecturer went to a pharmacy at noon on Jan 10 due to muscle pain and other symptoms, indicating he was likely at an early stage of the disease then, it ...

So, some will be pushing back - always welcome, albeit this is anticipated.

Rnaught is just an estimate.

The famous measles 12-18 is shown below.

But the R0 of 6-8 has the most estimates.
