No surprise to me, at all. Talked about these masks being ineffective last spring.

And of course, this say's nothing about eye protection.

Scientists or lab techs don't walk into a "bio" lab where they do do work on contagious pathogens wearing only a piece of cloth over their mouth and nose.

If this virus were as dangerous as they say it is, there would have been a mandate to wear an N99/N100 properly fitted mask along with proper eye protection beyond glasses/sunglasses.

Ping!

Stanford study quietly published at NIH.gov proves face masks are absolutely worthless against Covid

[Organic Panic]

But it does prove your fealty to our government overlords. Trust the all knowing Fauci the Magnificent..

[goodnesswins]

Hoping enough people see this and this idiocy ends

[SFmom]

So many grammatical and spelling errors. Was this really peer-reviewed?

[ProtectOurFreedom]

I reformatted the conclusion to draw attention to the list of ill effects...

Conclusion
The existing scientific evidences challenge the safety and efficacy of wearing facemask as preventive intervention for COVID-19. The data suggest that both medical and non-medical facemasks are ineffective to block human-to-human transmission of viral and infectious disease such SARS-CoV-2 and COVID-19, supporting against the usage of facemasks. Wearing facemasks has been demonstrated to have substantial adverse physiological and psychological effects:

• hypoxia
• hypercapnia
• shortness of breath
• increased acidity and toxicity
• activation of fear and stress response
• rise in stress hormones
• immunosuppression
• fatigue
• headaches
• decline in cognitive performance
• predisposition for viral and infectious illnesses
• chronic stress
• anxiety
• depression

Long-term consequences of wearing facemask can cause health deterioration, developing and progression of chronic diseases and premature death. Governments, policy makers and health organizations should utilize prosper and scientific evidence-based approach with respect to wearing facemasks, when the latter is considered as preventive intervention for public health.

Like using a chain link fence to stop humming birds.

I hope that the quote from the report citing mask “thread diameter” is just a misleading choice of words. I wouldn’t think it would be the diameter of the threads that matters, but rather the diameter of the gaps or holes between the threads. Of course, trying to visualize how that would look at the microscopic level, I suppose wider threads would leave wider gaps, kind of like trying to weave together a bunch of logs versus a bunch of toothpicks. Maybe that’s what they meant.

Viruses don’t have “wings” so actual virus size is mostly irrelevant to the mask argument. Viruses “ride” on saliva and “snot” (mucus excretions)...masks of any type reduce “ballistic” droplet (larger) transmission and the different but related “aerosol” transmission (very small droplets)...yes, N95, N100, etc. masks the best, but nothing short of a “positive pressure hazmat suit” is 100%.

The study was actually published in November 2020. So it has been on the NIH web site for at least five months - ignored for five months.

[RC one]

This is a bunch of BS. In one breath the author states that a mask is unable to stop the spread of a virus because the fibers are too far apart and the virus is so small. In the next breath he states that a mask somehow prevents the free travel of carbon dioxide and Oxygen molecules which are even smaller than a virus so...which is it

The author ignores the fact that masks are comprised of multiple layers of fibers, not individual layers. It's not like throwing a golf ball at a chain link fence, it's like throwing a golf ball at a hundred layers of chain link fence. And, for that matter, the virus is transmitted via droplets that are more like the size of a baseball being thrown at a hundred layers of chain link fence.

And; furthermore, multiple studies have shown that facemasks do not, in fact, cause hypercapnia or hypoxia. here's one that's so clear, even a caveman can understand it.De. Bunked.

Here are multiple videos demonstrating that facemasks do, in fact, reduce the transmission speed, distance and "hang time" of droplets.

Schlieren Imaging mask vs no mask

Mask no mask petri dish experiments

Laser imaging of droplet emission through no mask vs various styles of masks

Then the author cites the following study as evidence that wearing facemasks is pointless: 26) Leung N.H.L., Chu D.K.W., Shiu E.Y.C., Chan K.H., McDevitt J.J., Hau B.J.P. Respiratory virus shedding in exhaled breath and efficacy of face masks

This is the actual conclusion of that particular study:

I think we're done here. This isn't even a study. It's straight up BS.

[NobleFree]

The paper summarizes the first clinical study it cites (endnote 26) as follows: “The results of this study showed that among symptomatic individuals (those with fever, cough, sore throat, runny nose ect…) there was no difference between wearing and not wearing facemask for coronavirus droplets transmission of particles of >5 µm. Among asymptomatic individuals, there was no droplets or aerosols coronavirus detected from any participant with or without the mask”.

In sharp contrast, the abstract of that study reads: “Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.”

The paper is a flubro con job.

Many of us have known this from decades of hands-on experience with PPE but have failed to educate those millions upon millions of irrationally frightened people that they have been lied to -- persistently lied to for over a year -- by their beloved "experts" who damn well know that masks are completely -- totally and without doubt -- ineffective against transmission of a respiratory virus.

The challenge that simply and without compromise must be overcome is to convince people that they are causing serious harm in a variety of ways to themselves, to their children, to their society, to their country ... to their very quality of living by continuing to wear -- and continue to demand that everyone else, healthy or not wear -- these vile, dehumanizing, useless masks!

[FreedomNotSafety]

I’m anti-mandatory-mask for numerous reasons but this idiotic article about a seemingly flawed paper would not help my argument.

[9YearLurker]

I’m in the land of the blue state weinies. Believe me, I know their arguments:

- the big issue is not getting too big a load of exposure and spitum and the like are big clumps that would be more likely to be trapped within a sick person’s mask. Blah blah blah.

Face coverings = Islamization of America

[joma89]

Surprise! Government lied again.

[maddog55]

This has been well known for a long time with other studies as well but science is the last thing the government gives a damn about.

Another study, yet to be completed is the affect government mandates have one mindless idiots that do whatever they are told.

That study will find 75% of the population are very much like lemmings and/or sheep.
