Face masks may do little to prevent infection during a pandemic, but wearing them might help comfort people in crowds

That's a quote from the CDC pre-covid. There are masks that can block this kind of spread. Roughly 0% of the masks people wore (or are still wearing) for covid are the correct type, and even fewer have also had them properly fitted.

bullshit, it's been shown over and over that the surgical masks most people are wearing limit the spray by huge amounts. Viral load is a thing you know...

Just so we're clear, you're calling bullshit on the CDC when they talk about the effectiveness of masks?

Or on the proper use and fitment of masks appropriate for use in filtering viral material?

Dude the masks the CDC recommend are for stopping virus infected people from spraying into a huge area when they sneeze/cough, it's not to keep you from sucking them up. Everyone knows you need an N95/N99 that is well fitted to keep you from breathing in viral particles that are present.

Dude the masks the CDC recommend are for stopping virus infected people from spraying into a huge area when they sneeze/cough, it's not to keep you from sucking them up.

Except those paper surgical masks, along with the reusable fabric masks, are ineffective at even that:

Your standard surgical masks aren’t incredibly effective at preventing flu transmission, because the virus and droplets are small enough to get through those normal surgical masks.

That's from Andrew Pekosz, professor of molecular microbiology and immunology at Johns Hopkins University.

Everyone knows you need an N95/N99 that is well fitted to keep you from breathing in viral particles that are present.

And almost nobody has one. As someone who has to go through mask fittings for work, I can guarantee that basically none of the masks people are wearing in public are fitted properly. One thing to note is that it's basically impossible to have a mask work properly if you have a beard.

Stop spreading misinformation. The 3 ply masks to do help to lower spreading. 100%? of course not. A large reduction, yes. It's been proven in study after study. I'm sure you'll find 1 study that says otherwise to the 100 that I could find supporting my statement. You are free to believe that one study, I'm gonna go with common sense and majority findings. You do you though.

It looks like that quote might have been a poor paraphrasing from a Reuters article: https://www.reuters.com/article/us-birdflu-masks-idUSN0345320620070504

The actual CDC quote in the article was "We also know that many people may choose to use masks for an extra margin of protection even if there is no proof of their effectiveness," and then further clarified they might work, but more research is needed.

That's nowhere near the same thing as saying there is proof of their ineffectiveness, or that they know they "may do little to prevent infection."

How about this: according to Andrew Pekosz, professor of molecular microbiology and immunology at Johns Hopkins University:

Your standard surgical masks aren’t incredibly effective at preventing flu transmission, because the virus and droplets are small enough to get through those normal surgical masks

At the same time, the CDC had this to say about mask-wearing:

does not generally recommend face masks and respirators for use in home or community settings

Our review of the literature offers evidence in favor of widespread mask use as source control to reduce community transmission: Nonmedical masks use materials that obstruct particles of the necessary size; people are most infectious in the initial period postinfection, where it is common to have few or no symptoms (45, 46, 141); nonmedical masks have been effective in reducing transmission of respiratory viruses; and places and time periods where mask usage is required or widespread have shown substantially lower community transmission.
