Nope, any "masks work" references are to fraudulent, biased, lab environment studies that are not peer reviewed, and carry zero relevancy for medical based decisions.

I looked last year. All the credible mask studies I was able to find were for the medical community. I read about 30 of them and found no studies in favor of masks for the public or to prevent a virus. Most recently there is that NIH study that says they are useless.

Masks don’t work to stop the transmission of virus particles. Period. https://www.rcreader.com/commentary/masks-dont-work-covid-a-review-of-science-relevant-to-covide-19-social-policy

Unknown Aspects of Mask Wearing Many potential harms may arise from broad public policies to wear masks, and the following unanswered questions arise:

Do used and loaded masks become sources of enhanced transmission, for the wearer and others?

Do masks become collectors and retainers of pathogens that the mask wearer would otherwise avoid when breathing without a mask?

Are large droplets captured by a mask atomized or aerolized into breathable components? Can virions escape an evaporating droplet stuck to a mask fiber?

What are the dangers of bacterial growth on a used and loaded mask?

How do pathogen-laden droplets interact with environmental dust and aerosols captured on the mask?

What are long-term health effects on HCW, such as headaches, arising from impeded breathing?

Are there negative social consequences to a masked society?

Are there negative psychological consequences to wearing a mask, as a fear-based behavioral modification?

What are the environmental consequences of mask manufacturing and disposal?

Do the masks shed fibers or substances that are harmful when inhaled?

This is a great rabbit hole. There have been quite a few papers that have come out in this last year on the amazing effectiveness of masks at reducing viral transmission. They all start with the same axiom. For example, from this paper.

The masks help mitigate the risk of cross-infection via respiratory droplets

Or from this paper:

COVID-19 spreads primarily through respiratory droplets exhaled when infected people breathe, talk, cough, sneeze, or sing.

Or this one:

Similarly, SARS-CoV (2003) (3), MERS-CoV (2012) (4), and the recent SARS-CoV-2 (5) are transmitted via droplet/aerosols

This is the base axiom for numerous studies which go on to show how masks can effectively stop these exhalation droplets.

Where does this axiom come from? Is there science on that?

This is from the CDC:

COVID-19 is thought to spread mainly through close contact from person to person, including between people who are physically near each other (within about 6 feet).

Mmkay. Where's the link to a study that shows that CDC?

Bueller?

Bueller?

I can't find any evidence that supports this statement from the CDC.

It's like someone just threw the idea out there, and it became accepted science.

They seem to be creating scientific truth (which every scientist knows is an oxymoron) de novo.

There are many papers that use this axiom and provide compelling evidence that masks work. I have seen no papers that test the axiom itself and provide compelling evidence that masks work, or that the virus (or any virus for that matter) are transmitted in this way. In fact, they provide evidence to the contrary.

Even articles that are sited as showing that the virus is spread through these droplets are actually saying the opposite! The third paper I selected above links to this article to show that SARS-cov-2 is transmitted by droplets. This is what that article has to say:

The National Academy of Sciences (NAS) has given a boost to an unsettling idea: that the novel coronavirus can spread through the air—not just through the large droplets emitted in a cough or sneeze.

This is the science we are supposed to be following (into our eternal slavery).

It creates, out of thin air, "science" that says that the virus we must all fear as death knocking on our collective door is transmitted via water droplets that we exhale. There is no evidence, it is instead just a spell that is being cast. A wave of the hand, and ALAKHAZAM! a new reality is created.

This is the only reality where a virus that is 120nm can be blocked by masks with holes that are 10,000nm wide. Therefore, that is the reality we live in. There is no science that questions that reality that is approved.

The cake is a lie.

Take a piece of chain link fence... and make it into a fly swatter.

How effective is it at swatting flies?

Same for the effectiveness of fabric masks vs. microscopic viruses. :>)

I think a better question would be to ask, why can't they isolate the virus.

I didn't. I also argued with many people online about it, and they weren't able to proof I'm wrong.

There was a Peer Review study by BYU. It was the worst amalgam of circular and illegitimate references I have ever seen. They referenced fuking WAPO, VOX, and the Atlantic. A “scientific study”. It was almost satire. Shortly after dozens of libtard news orgs used it to perpetuate the mask lie ( last spring). People will believe any bullshit u throw at them. Just label it ‘science’ and sell it as legit in the press. Idiots.

If any kind of mask even slightly worked, FDA,CDC and the WHO would've standardized and mandated It and the manufacturer(likely chinese) wouldve made a boatload of money

I read many, and the most positive about masks were still in the "sometimes in certain circumstances some masks look like they might have helped reduce transmission by up to 2%." Which is pretty poor and generally goes with the old saying "negative results don't get published." And if you don't get published you don't get funded. Many studies are busy work for grad students too.

In terms of filtration, N95 (The best of the masks people wear) means that it stops 95% of particles at 0.3 microns. Far larger than any viral material. Also assumes that the mask is perfectly sealed to the wearer's face, which is rare at best.

In order to protect cross-contamination in a hospital setting, what's most common is a HEPA filter that stops 99.97% of 0.3 microns. So, because they can't guarantee that it will block any contaminants they will typically ALSO have duct mounted UV lights to kill off anything that might slip through.

As far as PPE, like with virologists who actually work with viruses, the only guarantee is through a Self-Contained Breathing Apparatus with an air supply, typically over-pressure so if any leaks occur the clean air blows out rather than contaminated air leaking in.

Not effective at preventing viral spread, potentially harmful with regard to bacterial infection. Widely known prior to 2020.
