Povidone Iodine Oro-Nasal Spray: Effective Shield for COV-19 Protection

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. 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.

This thing is riddled with typos.

  English isn't the author's first language, I doubt you'd do better in Bengali!

    No problem with people who know more than one language (even without complete written fluency)… but why not have some third party editing/proof reading? Especially when submitting research to the NIH--which will live on in posterity. Poorly written papers reduce the readers ability to focus on the content, however well researched.

  There's also not really an evaluation section. So how can we conclude it is effective?

  Having seen the photos, I'm just glad it's written in English.

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). https://pubmed.ncbi.nlm.nih.gov/33865974/ https://pubmed.ncbi.nlm.nih.gov/33865974/ 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 less 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.S. A lot of this info seems to be behind paywalls. If anyone has a better URL to use, I'd appreciate that.

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.

  I don't see why that's a problem as long as it's done away from treatment areas, preferably behind barriers and filters. AIUI this is already standard practice e.g. for handwashing or changing PPE anyway.

  > The study found that povidone iodine "may reduce the carriage of infectious SARS-CoV-2 in adults with mild to moderate COVID-19"—but that means it was found to only reduce the amount of virus in a person's nose when they're already infected with COVID-19. That certainly sounds like a positive, unless you think viral load doesn't matter? Based on the study from your article, it seems that a careful few day course of this treatment after known exposure could help prevent significant infection. At the very least warrants further study. The cons in that article make the assumptions people will swallow it and then some non-sequitur about deterring vaccination. Not a great argument, doc.

Is it more effective than bleach?
