Could nasal irrigation and oral rinse reduce the risk for COVID-19 infection?

Manuele Casale et al. Int J Immunopathol Pharmacol. 2020 Jan-Dec.

Abstract

Public health measures are essential to protect against COronaVIrus Disease 2019 (COVID-19). The nose and the mouth represent entry portals for the COVID 19. Saline Nasal Irrigations (SNIs) can reduce the viral load in the nasal cavities. Oral rinse with antimicrobial agents is efficacious in reducing the viral load in oral fluids. We advocate the inclusion of SNIs and ethanol oral rinses as additional measures to the current public health measures, to prevent and control the transmission of any respiratory infectious disease, including COVID-19.

Keywords: COVID-19 infection; oral rinses; prevention; saline nasal irrigations.
