Saline nasal spray and 1% PVP-I. Povidone-Iodine solution. Comes in 10%, but dilute down to 1% in saline solution. (Some have gone lower to .6% dilution)
Saline solution is 1/2 teaspoon of salt per cup of distilled water, (or boiled water) allowed to cool.
Deactivates Sars2 in 15 seconds.
Also - Listerine Cool Mint, using essential oils, destroys Sars2 virus in seconds. Gargle 3X a day and use the PVP-1 nose wash, and you have reduced the odds of getting and spreading Covid.
Consult your physician.
Virus begins in nose, throat and mouth and works its way to the lungs, yet daily irrigation and gargling can stop it from spreading.
Good advice, thanks.
