Evidence that Masks seem to be effective against Covid (2022)
cdc.govLiterally the meme of a giant stack of evidence vs. the one study that confirms your bias. Masks don’t stop respiratory illness. It was established fact before it became a political wedge issue.
Depends on type and fit of the mask. And yes they don't stop it, but they reduce the odds of transmission, less so or more so depending on the space they're used in.
Cdc link? Lol
