Coronavirus Disease 2019 (COVID-19) has infected more than 8 million people
globally since its discovery in December 2019. For COVID-19 prevention, the World Health
Organization recommended regular handwashing with soap, cough etiquette, mask wearing
and social distancing. However, COVID-19 is rather difficult to contain because of its high
transmissibility property. Gargling is effective for reducing infection in the respiratory tract.
Most antiseptic gargles have antimicrobial properties against common respiratory pathogens.
No published study on the effectiveness of antiseptic gargling among COVID-19 patients has
been available to date. This article reviewed available literature on methods and solutions
available for gargling and their effect on respiratory tract infections.
