AT BEST we can say that there's very low quality evidence that highly adherent mask use may modestly reduce the likelihood of infection for people wearing them, although this has not been demonstrated in the majority of trials

Do you think if everyone wore a mask when going out it would help prevent asymptomatic spread, not via protection of the user but by preventing the user from releasing infectious droplets?
