Thanks Kent for noting that the article in question was from May. With such a fast moving situation as Covid, a 5 month old article is like ancient history. Multiple studies have since shown the efficacy of masks in experimental studies. While not perfect, they’re all we’ve got at present (plus common sense).
There is a reason that the New England Journal of Medicine has not retracted that article. The article in question read in its entirety was a little more nuanced and laid out a few more guidelines than were spelled out in that first paragraph, but as a simple statement of fact the first paragraph has not been contradicted by any actual research. There are not”multiple studies” that have shown the efficacy of masks, per se, in stopping the transmission of this disease in normal everyday situations. There are not multiple studies, there are zero peer reviewed studies in scientific journals which have demonstrated this. Because it’s mostly false. Go ahead, link a legitimate journal article with a rigorous methodology and solid statistical analysis which concludes that masks are effective in preventing the transfer of this particular coronavirus in general human activity, and making people sick. Actual research, not something reported in the newspaper written by the “science editor”.
Transfer of a viral load large enough to cause the disease generally takes close contact for 30 minutes or longer, closed quarters, close proximity, eyes mostly. Hands to eyes. Hospital situations, nursing homes, sick people next to susceptible, compromised people for extended times, the family home, that’s the nexus. That’s where the cases are. That’s where masks are justified as part of an overall regimen. Wash your hands, don’t touch your eyes, wash your hands some more, use hand sanitizer. People getting sick out in public, just walking past other people, even in crowds, mask or no mask, just isn’t happening, because that’s not how this works. The virus will go right through anything short of an N95 mask, and only an N100 mask would stop most of it, and the eyes are still uncovered. But, people on the street, or in the grocery store just passing by others for a couple of minutes, that’s not how it is transmitted, and masks there do nothing, even Fauci has admitted as much.
Medically, they way they are being used, with the general mandates, they do nothing at all, but, non-medically, by providing some level of constant, visible, psychological awareness that keeps people on their toes, there may be some benefit there, but the masks themselves are not doing anything except window dressing and keeping people on edge.
If people want to wear a mask because it makes them feel better, that’s fine.
Not only are there no actual studies showing that masks themselves are generally useful at preventing spread, none of the epidemiological data, who gets sick and who doesn’t, supports this. And yes, we do know much more than we did in March.
I know this will raise some hackles, because I know where most people get their information, and I know how widespread the misinformation is. An abundance of caution is one thing, but this seems to have gone well past that at this point.
I spent several years conducting a weekly seminar at the post doctoral level on how to evaluate medical scientific literature, which studies are done correctly and which have obvious procedural or statistical flaws, and am tired of hearing things repeated over and over, things that “everybody knows”, that are simply false. There is a great deal of fear mongering out there, and I do not know exactly why that is happening as it seems to be more than “if it bleeds, it leads”.
