Povidone-Iodine Vs Essential Oil Vs Tap Water Gargling For COVID-19 Patients

Summary

The purpose of this study is to assess the ability of regular gargling to eliminate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the throat and nasopharynx. This 4 arms interventional study compares the effect of gargling using povidone-iodine, essential oils- based, tap water with control (no intervention) among Stage 1 coronavirus disease-2019 (COVID-19) patients. Findings from this study will provide new insight into the importance of gargling in the treatment and prevention of COVID-19.
