FWIW, here's a more comprehensive overview of the literature in this area, covering not just povidone iodine but also hydrogen peroxide and cetylpyridinium chloride (CPC).<p><a href="https://pubmed.ncbi.nlm.nih.gov/33865974/" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/33865974/</a><p>I remember seeing articles about this even earlier, very early in the pandemic. I honestly haven't made up my mind and am not taking a position. I'll just add that I've been using CPC mouthwashes for years because of their general effects, and this doesn't make me any <i>less</i> likely to keep using them. What seems odd to me is that they seem to have become less common in the last several months than they used to be. Not sure why.<p>P.S. A lot of this info seems to be behind paywalls. If anyone has a better URL to use, I'd appreciate that.

This is apparently written by a surgeon working at high risk of covid-19 transmission, spraying himself and patients with a known (and safe?) virus killing agent in addition to standard ppe.<p>This sounds plausible to my layman ears (certainly not as dubious as ivermectin etc) but perhaps too-obvious-simple-good to be true. Upvoted in hopes someone knowledgeable comments.
Taking off the mask to squirt the spray seems risky anywhere in the hospital. I doubt crowded hospitals will adopt this protocol especially with a more transmissible variant.
