covid, cheap preventatives
evidently there is some precedent for using DILUTE iodine as a sinus rinse & gargle during respiratory outbreaks, and they were in fact trying this in Italy.
given how cheap and widely available Betadine & generics are, this could be useful if e.g. your housemate / partner gets sick and they want to avoid spreading it, you want to avoid getting it, etc.
obviously not something we'd likely do in regular times, but if you're high risk.....
