It should be blindingly obvious that a mask, any sort of mask, on a sick, coughing person acts to limit the quantity of infected sputum put into the air. Confusion arises on the right in particular because those guys simply cannot understand why they would wear a mask if the benefit is chiefly to other people. I really wish it were first clarified in these discussions whether we are talking about benefit to the wearer or benefit to people around the wearer. The distinction appears to be completely absent both in the article and in the comments here on HN.
