I did read through all of them and all of them are about cotton and surgical masks. All also say n95 masks are effective at limiting the spread and exposure for both infected and uninfected. They all also say we need to reserve these types of masks for our medical professionals because there is a shortage (which as the guy before states, these are all outdated and n95 masks are more available). Lastly, they don’t say they don’t recommend them so if you knew anything about evidence-based medicine, you’d know all that goes into establishing a formal clinical recommendation (which is what I do for a living by the way - I write evidence based health policy). Right now the best we can do with the limited evidence is come to broad conclusions based on expert consensus until the research catches up.
Most interesting to me is what the guy before me points out. What is your motivation to spread misinformation if it to hurt all Americans? Gtfo you un-American turd spreader!
