Conclusion
VIRUS, CAVITY
Since the oral cavity serves as a reservoir of SARS-CoV-2, using mouthwashes can be effective in Covid-19 patients to prevent the transmission of this virus. PVP-I at 0.5% and 1% concentrations reduced the viral load of SARS-CoV-2 in oropharyngeal, nasopharyngeal, and saliva specimens. Thus, it might be considered as a simple and inexpensive intervention during the Covid-19 pandemic.
