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.

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.

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....

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

Thank you @BarryHunt008 for flagging this.

You've heard of "The Three Problem." - great book, and excellent Netflix series.

If you want to be avoid catching Covid, you probably have "The Empty Room" situation in the back of your mind.

How long after a room had people in it, can you safely demask?

/1 3 body problem netflix cover showing a eye with a countdown running in it.  That was a countdown to each person's death. Measles was thought to be airborne after a child caught measles an hour after the infected child left the same office.

.

Interestingly, you can see the reluctance in blue below to call measles airborne. Much like the WHO with @mvankerkhove researchgate.net/publication/19…In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The...

Fit factor of 250- 4000 versus the normal 100-200 for an N95? Where do I sign up?

Oops, that's here. With me. Starting a build with an Ebay'd Bullard EVA PAPR's filter - and some DIY loving goodness of a heat gun and PVC pipes.

The benefit of this build will be the over 10 hour run-time of the massive battery on the PAPR.

I have a new thing to say to why I mask.

Ronald Reagan, Michael J Fox, Robin Williams, Lou Gehrig, Bruce Willis.

Alzheimer's, Parkinsons, Lew Body Dementia, ALS, CJD

All of them are dying or are dead from - the common cold.

You see, One of the main viruses that results in the cold is a virus called OC43.

And it turns out that it's neuroinvasive - and is strongly associated with all of those diseases.

Even though it's just a cold in the beginning. So, those are 5 really bad diseases that I am protecting

Safer showering and swimming with great breathability!

Others have used a snorkel w/ N95s - but those then collapse around the snorkel, and breathability is more restricted. This new approach is w/ an internal BRACE!

I took a shower with this, and it worked perfectly. Build 🧵 Image This is a great technique, but I was looking for something with more breathability.

Got bored. Let's just check out Google Scholar and E Coli. Oh my. Oh my, that's not good.

Yes, yet another episode of "that's airborne, TOO?!!!!!"

"Airborne E. coli were isolated from indoor air,....and downwind air samples (10, 50, 100, 200 and 400 m away) for five swine houses" (1)

Cows:
"E. coli was isolated in both inside and outside air, even in samples taken 150 m from the farm." (2)

He died from not masking.

Not masking led him to getting polymicrobial respiratory infection (multiple pathogens) on 2/6/2025, leading to bronchitis, to bilateral pneumonia, a respiratory event

Trump is trying to distract from the economy. He just pumped out the Lab Leak from the official whitehouse.gov website.

Simultaneously making masking advocacy both more difficult and easier.

But, anyway, what do I mean? On the one hand, pointing out that Covid is probably a bioweapon means that you can point out the silliness of not protecting yourself against it.

@TheAtlantic @danengber Heh - I suspect Mr. Engber has been eavesdropping on my (and my fellow Covid Conscious) swimming safer threads. I have a new solution for showering safer for that I will be rolling out tomorrow.

For future articles by those who will come along, let me point out a few things /+ @TheAtlantic @danengber Thank you very much for pointing out that 4% of America is still masking 100% of the time! That is 13.2 million Americans.

The Masking Nation is larger than 38 states. :)

But, 18% of us masking some of the time in the SAME PEW POLL (tch tch). You would think that would be/+ At a basic level, their COVID-conscious attitudes may not be so far from the mainstream. Twenty-one percent of Americans still think of the disease as “a major threat” to public health, according to a recent poll from Pew Research Center. Thirty-nine percent say we’re not “taking it seriously enough.” But if 50 million to 100 million adults harbor such concerns, very few are doing much about them. Masking rates were once as high as 88 percent; now they’re close to nil. For those who still maintain their masking habit—4 percent, says Pew—the whiplash in social norms has been a shock.

This may be one of the most important studies in a decade.

#LongCovidBinder.

"The models produced correctly classified those with severe ME/CFS from recovered controls with an accuracy of 97%, sensitivity of 94%, and specificity of 100%. "

THAT IS HUGE. "We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. " We found that at Stage 1, those fated to develop ME/CFS 6 months following IM had low levels of IL-5 and IL-13 [25]. IL-5 enhances the production of B1 cells which are anti-inflammatory (impaired B1 cells have been found in multiple sclerosis, systemic lupus erythematosus, and rheumatoid arthritis), and IL-13 has anti-inflammatory properties. Jason et al. [26] also found that students who failed to recover from IM had more restricted, inflexible cytokine networks whereas those who recovered had more flexible, less interconnected networks. Network analysis suggests that IL-5 and IL-13 influe...

A new study just showed what I have been saying since the start of bird flu. H5N1 is airborne.

Still in place?
USDA: YOU ONLY NEED TO TEST LACTATING COWS.

oops.

USDA: FOMITES (infectious objects) SPREAD IT.

oops.

WASHING YOUR HANDS WILL STOP IT.

oops. This new Federal Order does not override or supersede USDA's April 24 Federal Order, which still requires the mandatory testing of lactating dairy cows prior to interstate shipment and requires that all privately owned laboratories and state veterinarians report positive test results connected with those tests. The new Federal Order announced today is intended to complement and enhance this existing order.
Question [00:51:52]  Given the CDC's vaccination program, I'm wondering if this means you think it's no longer realistic to expect that the outbreak will be contained this year?  Eric Deeble, USDA [00:52:12]  Just on the animal side and all that Dr. Nirav speak to the human side, there's a lot about this disease that makes us feel as if we can arrest its progress.  And we've actually seen some success demonstrated to date.  With this disease, it does not appear to move by respiratory transmission. We know that there are high viral loads in milk, and we've identified through close, collabora...
In addition to testing, biosecurity is the key to containing this virus, and ultimately ensuring that it is eradicated so that producers do not have to deal with this virus in dairy cattle permanently. Good biosecurity including cleaning and disinfection of vehicle and equipment - is critical to minimizing the risk of disease spread. USDA works closely with state animal health official, producers, and industry organizations to provide guidance and resources for cleaning and disinfection not only on affected farms but for all livestock producers as a part of practicing good biosecurity.

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

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-...

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.
