This has never been proven. Please find me an RCT that shows this. I'll wait.
BTW, this is a doubly wrong statement for cloth masks, since cloth masks have plenty of studies showing increases in self-infection, at least relative to wearing a surgical mask.
- edoceo 5y agoI just looked, found a whole bunch of stuff on CDC site showing RCT that demonstrates masks do work and that N95 are better than cloth. Where's the RCT that shows they don't work? I couldn't find one.
- __blockcipher__ 5y agoWhat RCTs are you referring to? I’d like to take a look. Ones showing don’t work: DANMASK (sars-2 community self infection) Macintyre et al (cloth masks vs “standard practice”, showed possible deleterious effect of cloth masking but did not compare to no-mask)
