Simple Mouthwash for COVID-19 proves effective before surgeries.

Povidone-iodine (PVP-I) is readily available and acts as a broad-spectrum antiseptic solution that easily kills bacteria viruses and fungi. It is normally used for skin disinfection before surgery. In vitro studies have shown the same potent efficacy against COVID-19 as well other viruses. . It can be used Safely as a mouthwash or intranasal wash.

The American Dental Association has guidelines for reducing transmission of COVID-19, including the use of a preoperative 0.2% PVP-I mouthwash. Studies have shown dramatic reduced viral load that can last for up to four hours following this protocol.

The PVP-I solutions usually provided as 1% could be diluted with NS or sterile water (1 ml of PVP-I added to 19 ml of NS or SW Will result in 0.2% solution). Gargling the solution for 30-60 seconds in the mouth and disposing of it after would be an effective mouthwash. The 0.2% PVP-I could be administered intranasally before an aerosolizing event like dental procedure or intubation
