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?
But....maybe it's not all bad news.

Because that 4% becomes 18% when you include those who mask some of the time.

And.... 18% mask so e of the time.
Look at this - some of the time....

Black: 39% mask
Hispanic: 27% mask
Asian: 32% mask Look at this - some of the time....  Black: 39% Hispanic:  27% Asian: 32%
60% of Democrats worry we’re not taking COVID-19 seriously enough, 76% of Republicans disagree 60% of Democrats worry we’re not taking COVID-19 seriously enough, 76% of Republicans disagree
Six-in-ten Democrats say it’s extremely or very important to wear a mask in crowded settings when people have cold-like symptoms, compared with 26% of Republicans who say this. Six-in-ten Democrats say it’s extremely or very important to wear a mask in crowded settings when people have cold-like symptoms, compared with 26% of Republicans who say this. A similar share of Republicans (25%) say it’s extremely or very important to take a COVID-19 test, versus 57% of Democrats.
Lol. Only 63% have had C0V1D. 63% have had COVID.
17% feel COVID presents a risk to their personal lives.

@CDCgov 👀. Image
17% of Americans say that C0V1D is a major threat to their finances. Image
There is more, but those are the highlights.

Or lowlights.

Lots of framing in the poll itself that was ...leading.

So, I got curious.

Despite the pore sizes of the N95 filtration being so much larger than CO2 molecules, there is a greater concentration of CO2 in the N95, than outside.

Why?

We exhale 4–5% CO2 (40,000–50,000 ppm), much higher than the ~0.04% (400 ppm) in ambient air. Image
What is the the AVERAGE CO2 in the dead space below an N95? 1-3% - or 10,000 to 30,000 ppm.

Sounds scary high, right? It's the AVERAGE. Below you can see it rise and fall. See how at the end of the inhalation it's almost zero?

But what happens to that CO2? We inhaled it Image
all, so we must be poisoning ourselves!?

Nope, here is what is going on with our alveoli gas composition.

Not much of a change.

And that gets reflected in the amount of CO2 in our blood.

That is best measured by PaCO2 (arterial CO2 partial pressure). Image

Are you reading this thread because you said you were worried about CO2 in an N95?

Hypercapnia?

1. Don't worry - be happy. This thread explains why you should not be worried about those things.

2. If still worried? We'll get to what YOU can do about it.
In 1998, long before the mask controversy of 2020, the OSHA Respiratory Protection Standard was passed.


Cntrl F for
"carbon dioxide", "dead space", or "physiological burden".

Before they passed it, they consulted industry, unions, academic researchers. osha.gov/sites/default/…Image
Image
Image
Image
Dozens of studies addressing CO₂ buildup, dead space, and other tolerability issues in respirators.

Seriously, Cntrl F above.

But there is a long history they built upon within NIOSH AND OSHA - AND before.

Tired: Infectious fecal and respiratory aerosols.
Wired: Infectious urine aerosols.

Do you know how many aerosols you generate at the urinal, standing up?

Do you know how many aerosols you generate on the toilet, sitting down?

Do you know you have a thermal plume lifting
both up to your breathing zone?

Do you know that you can get an N95 at Home Depot or Lowes - and you can wear it into their public restrooms?

Studies to come to avoid the Musk Masking algorithm.

"COVID IS OVER, YOU DON'T NEED THAT!"

Reason 4,657 on why I mask now that I understand aerosols and transmission. It's not all about COVID.

This is Chicago, but it's really Anytown, USA. Image

.Why I mask in more details...

EV-D68. An enterovirus - many people think enteroviruses are strictly fecal-oral.

They think wrong ( this is not a subtweet at Dr. Johnson).

How do we know TB is airborne?

71 guinea pigs gave their lives between 1956 and 1958 in the eponymous study by Riley et al, getting TB air piped in from some TB patients, to prove TB is airborne.

Influenza is kind of airborne per most doctors. But kind of not.

So....

We need some volunteers.

Will horses be those volunteers that finally lay it all out?

Yes - but none of them lost their lives.

Air samplers were deployed and tracked horses inoculated with Equine influenza virus (EIV).

From the very first day post inoculation (dpi), until the Image
12th day, EIV was found in the air, in this new study.

With no horses, or guinea pigs, hurt in the process.



But sure, influenza's not airborne - if you are the USDA, right, @nirav_maine?

Of course, yet another new study points an accusatorysciencedirect.com/science/articl…

Thank you @BarryHunt008 for flagging this.

@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.

Lol.

They are just apparent supplement grifters.

I noticed they were using @NukitToBeSure's excellent torches as their example picture.

Strange to be so selective of an example picture for someone purporting to be an independent news source on health.

Hmm. I helped defend Nukit against charges of Image
racism by a very nasty couple who it turned out just do not like UVC, personally. I wonder....

Yep, ThailandMedicalX has blocked me.

But, it's weird for a purported news source to block someone like me @gorskon
@doritmi @19joho.

And them blocking me, is probably because Image
