And what’s the efficacy of valveless masks at reducing spreading? Given that even places with extremely high mask compliance are experiencing the same spikes as everywhere else, I have trouble believing that the benefit from masks is anything but marginal, since very few people are wearing N95 respirators. Meanwhile, for that marginal benefit everyone is being subjected to the discomfort of constrained breathing, the psychological impacts of not seeing faces/expressions, and difficulty for the hard of hearing (who rely on seeing lips/expressions). A recent study found that masks provided little benefit (https://fee.org/articles/new-danish-study-finds-masks-don-t-protect-wearers-from-covid-infection/ https://fee.org/articles/new-danish-study-finds-masks-don-t-...) but I haven’t been able to find exact numbers on the probabilistic reduction in transmission on a per-mask-material basis.
