“We know that respiratory viruses gain entry to the body through the nose,” Dr. Cohen said recently. “And we know that SARS-CoV2 is predominantly a ciliated cell infection, followed by viral replication and shedding into the mucus and neighboring cells.” Penn Medicine 
​Their studies are now applied to Covid 19

​The antiviral activity of iodineWhile mitigation measures such as lockdowns, masking, social distancing, and vaccines have been adopted to reduce the transmission of SARS-CoV-2, several other methods of reducing and controlling the virus have been proposed. Oral and nasal sprays with antiviral activity against SARS-CoV-2, for example, are actively being studied. More specifically, an Intranasal Povidone-Iodine (PVP-I; 1.25%) spray has been found to be active against SARS-CoV-2, as well as SARS-CoV and the Middle East Respiratory Syndrome (MERS).

​“Iodine is established as having a broad-spectrum antimicrobial activity against bacterial, viral, fungal, and protozoal pathogens and has been used as an antiseptic for the prevention of infection and the treatment of wounds for decades.”
