Several studies have found that the saliva of SARS-CoV-2 infected people has high levels of viral RNA, and aerosols generated from saliva can act as a potential route for viral transmission. According to a study published on the preprint platform bioRxiv, cetylpyridinium chloride-containing mouthwashes can inhibit SARS-CoV-2 in the oral cavity and reduce the risk of viral transmission. Study details An in vitro study was conducted to assess the antiviral efficacy of 0.07% cetylpyridinium chloride (CPC) containing mouthwash and 0.2% chlorhexidine digluconate-containing mouthwash against SARS-CoV-2 and its variants, including B.1.351, B.1.1.7, and P1.
Different mouthwash formulations including CPC with flavor, CPC with flavor and herbal mix, and chlorhexidine digluconate with flavor were tested for the study. 70% ethanol and water were used as positive and negative controls, respectively.…
