In a study conducted on 75 COVID-19 patients, the effect of SARS-CoV-2 on viral load was investigated as a result of the use of hypochlorous acid and povidone-iodine as an oral antiseptic.

Before and 30 minutes after rinsing with mouth antiseptics, the participants were asked to rinse the mouth and throat for 30 seconds with 0.9% isotonic saline. The sample was sputtered into a sterile plastic container. The participants were grouped according to the type of oral antiseptics used. The effectiveness of SARS-CoV-2 viral load was investigated by rinsing the mouth and throat for 30 seconds with 20 ml of hypochlorous acid, povidone-iodine, and isotonic saline. Viral load was analyzed by RT-PCR analysis. The results were evaluated by statistical analysis.
