Povidone-iodine (taken nasally or as a gargle) kills viruses and bacteria. All types, including Covid, with 99.9% effectiveness according to numerous studies. Has worked this way (and safely) since the 1950's. Given that it's effective, and cheap to produce it's no wonder big pharma lobbied so hard for their own expensive partial treatments.

Yep did the gargle as well both times I had COVID. Tried nasal irrigation with the diluted form but it was just too much to handle so I used NeilMed instead. n=1 caveats, but both cases (the first one Delta) were mild.

Betadine gargle is 1% povidone-iodine. As a nasal spray dilute by 50% with water. Active protection for 3-4 hours minimum (again according to numerous studies)
