Trump stated back in April to much ridicule
"And then I see the disinfectant where it knocks it out in a minute. One minute. And is there a way we can do something like that, by injection inside or almost a cleaning?
Well well well Look what we have here.......exactly that. A commonly used antiseptic.
Intranasal povidone-iodine: A 15-second treatment with an experimental povidone-iodine nasal antiseptic solution appears to inactivate SARS-CoV-2, according to an industry-supported, in vitro study in JAMA Otolaryngology—Head & Neck Surgery. The effect was seen with povidone-iodine concentrations as low as 0.5%. The researchers caution that skin formulations could be toxic if administered intranasally and that the antiseptic should not be used in pregnant women, patients with thyroid disease, or those undergoing radioactive iodine therapy. They conclude: "Transnasal viral inactivation may not only prevent person-to-person spread of SARS-CoV-2, but may also diminish the severity of disease in patients by limiting spread and decreasing viral load delivered to the lungs. Povidone-iodine nasal irrigation may be beneficial for the population at large as an adjunct to mask usage as a means of virus mitigation." Randomized trials are under way.
