I've been casually researching books on viruses that I could find free pdfs for and searching the term "mask" in them (checking of course that they were books related to airborne flu or coronaviruses, and not computer viruses) and quite frankly... most of these books don't even contain the word "mask" anywhere in their text, or at most just have a vague recommendation to use them in a laboratory setting with no mention of their actual effectiveness.
I did find out that coronaviruses are between 200-400 nanometers big (for reference a human hair has a width of 80,000 to 100,000 nanometers and most cloth masks can't even stop hairs), the first virus was photographed with an electron microscope in the 1940s, polio was photographed in the 1950s, and that use of masks in hospitals became common to protect against bacterial infections in the 1920s and even then they recommended that they replace masks frequently, and that mask mandates during the spanish flu were basically ineffective.
Now I don't have access to current medical textbooks, but if masks are so effective and proven you'd think that any book about airborne viruses would mention mask use and how effective they were... unless masks were not effective against viruses.
For example: Methods in Molecular Biology 1282, Coronaviruses Methods and Protocols (springer protocols) a textbook on coronavirus copyrighted for 2015 (299 pages) Has the word "mask" once, but it does not refer to medical masks, but rather "masked" in how the virus infiltrates a cell. It has a fairly long section on "prevention" but it doesn't mention masks at all.
Obviously, given even recent college level textbooks related or focused on coronaviruses have no mention of masks in their text.
Imagine a meme, 50+ college level textbooks used in med schools do not have any information proving mask effectiveness against coronaviruses or influenza. Though it's a bit much to search for as just one person.
The narrative is that it's the swiss cheese method.
Masks don't work. Social distancing the healthy doesn't work. Locking down entire cities doesn't work.
But when all of this is done together, it works.
lol
Well then, let's just throw a rain dance in for good measure.
The next part of the Swiss cheese model is to deploy vaccines that don't actually immunize you.
I asked the same things (N95 vs cloth). The best explanation, came from Dr Drew. He said a N95 was best, but even if you didn’t have one, any mask would do. A big reason he cited was touching your face (nose / mouth) with hands. The mask doesn’t allow you to directly touch your face, which can be a key way for entry into the nose/mouth. I’ve also heard the virus does not float on air alone, it needs water droplets to travel. While only an N95 can keep out the virus, any tight cloth can provide a better barrier against larger water droplets. I still only wear N95s & believe that a lot will come out years from now. It may not be as simple as wear a mask / stay home.
There is scientific evidence that N95 is effective at filtering SARS-COV-2. There is no scientific evidence that cloth or surgical masks are effective.
This is as simple as it gets regarding mask filtration and effectiveness.
Obviously touching an infected surface and then touching nasal membranes or eyes can be a route of infection, but that is not exactly relevant to the mask discussion.
N95 masks are not effective. I have a post in my history with a link to another person with several studies linked.
There is scientific evidence that properly fitting N95 masks are effective at containing/filtering SARS-COV-2.
Here is one such example: https://www.tandfonline.com/doi/figure/10.1080/23744235.2020.1810858?scroll=top&needAccess=true
Can you repost your source to the contrary please?
Only from the wearer who is expelling large aerosol droplets, not individual virions. That is also for N95s, which is a recognized standard for PPE.
Cloth masks and 6 feet make about as much sense as rubbing your tummy and patting your head at the same time.
Quarantining people who show symptoms has been and remains the only effective method to contain epidemics and pandemics. Feel ill, stay home; everyone else, go about normal life.

marginal at best.
There is also one done on marines in boot camp who were very much following the instructions. I do not have a link at the tip of my fingers for that one, but I think it can be found.
There is 0 evidence that masks stop viruses, or fungus or bacteria infections in surgical environments. Why pray tell would you imagine that they stop this one disease?
That article is about the "DANMASK-19" study, which did not involve N95 masks:
https://www.acpjournals.org/doi/10.7326/M20-6817
The marine recruit study also does not involve N95:
https://www.nejm.org/doi/full/10.1056/NEJMoa2029717
The SARS-COV-2 virus about 0.12 microns in diameter and N95 masks protect down to 0.1 microns, with 95% efficiency.
Therefore it stands to reason that cloth masks are ineffective at filtering this virus, but properly fitting N95 masks are.
You asked about cloth masks.
Your original post was:
I asked for the source in direct reply to your statement, which was about N95 masks.
The fuck people,
https://thedonald.win/p/11ROGqAjnl/masks-do-not-stop-viruses-this-g/c/
Pretty fucking sure that I gave this link earlier.
And by the way, I was going to, but thought, hey, be nice, but now, the fucking virus (if it even exists at all, based solidly on the argued number of RNA chains) is 0.6 microns not over 1 micron. N95 does not stop it. AND NO ONE IS FUCKING WEARING N95 masks anyways. And if they are, they are sure as fuck are not wearing them right or changing them often enough.
Every fucking place with the strongest mask mandates have the highest per capita infection rates, you can see the future just by seeing a mask mandate implemented. Shortly thereafter cases start a steep incline upwards.
Florida on the other hand, no allowed mandates by government, holds steady. California with the strictest is skyrocketing.
Again, your link refers to cloth masks, not N95. I provided evidence that N95 is effective, you provided no evidence to the contrary. Since this is obviously a religious discussion for you, and not a scientific one, there is no point in continuing this conversation.
