New study on wearing cloth face masks: protection is “statistically insignificant”
The one thing everyone seems to agree on is the fact that a person who is infected and symptomatic can reduce (not eliminate) the amount of virus they spew into the air when coughing or sneezing. It s still nowhere close to being 100% effective, but they at least have a chance of attenuating the amount of the virus that gets launched into the environment. But once it s out and floating around, it appears that masks for the uninfected have, as one study author put it, a symbolic effect for the wearer, but a mask does not substantially reduce risk.
