Sigh. The 'if it's not 100% effective, it's completely ineffective' argument is one that really rubs me the wrong way in any context, not just Coronavirus, because it's a strong sign that someone is being intentionally argumentative and disingenuous. Even a bandanna or fishing sun gaiter over the face will substantially reduce the maximum distance droplets from a cough will travel, per this study, from about 8' to 3' for a bandana, down to about 2.5" for a quilted fabric mask. https://www.kcbd.com/2020/07/01/bandana-is-least-effective-form-face-mask-study-says Is either of these as effective as a non-vented N95 mask? No, of course not. Will either of them protect you fully from breathing in a virus-laden droplet? No, of course not. Is reducing the distance you spew your potentially-toxic liquids a real and substantial method of mitigating virus spread - yes, absolutely. While obviously not as effective as a properly fitted N95/N100 mask, or a positive pressure respirator, ANY face covering creates a substantial reduction in outgoing virus-laden droplets, and will also catch many incoming droplets. Would it be better if we had enough N95 masks for everyone? Of course. But somehow, we're more than six months into this and STILL don't have anything like enough PPE in production, in part because the Feds haven't taken it seriously. Same story for teaching the general public how to use these masks to get the most effectiveness out of them. Look, I don't like wearing a cloth or surgical-style mask one bit, just like everyone else. We ALL know they're less effective than we'd like them to be, and wearing/using them incorrectly further reduces their effectiveness. But unless/until we source a billion or so N95's, cloth and surgical-style masks what we have to stand between us and the possibility of ending up on a ventilator for a month or worse. It sucks, but it's all we have available at this time. I profoundly wish the Feds and state-level health departments were doing a much better job of educating people about the differences in effectiveness between t-shirt material, bandannas, layered cloth, surgical-style masks, etc... but doing so would mean admitting that they're not as good as N95+ options would be, so they're staying quiet. PPE, hand sanitizer and vast amounts of hand washing are our best tools for keeping things open and recovering the economy. IMHO, if we'd had a functional PPE stockpile up front at the state, county and federal levels, we'd never have gone through the whole shutdown insanity... but without even enough PPE for medical personnel, much less the general public, we ended up shutting down and having to drop a couple TRILLION dollars on stimulus. All because we didn't have masks, and now we're doing it again because people claim that masks aren't worth wearing unless they're perfectly effective. Cloth masks aren't anywhere near perfect, especially bandannas. But they're a huge improvement over nothing at all.
