Methods
We conducted a search of the PubMed/MEDLINE databases for articles
relevant to topical agents with virucidal activity against
coronaviruses. Search terms included: alcohol, peridex, iodine,
chlorhexidine, topical, mouthwash, virus, coronavirus, COVID-19. To
focus the search, we concentrated on articles that focused either on
in-vitro studies or studies examining their utilization on mucosal
surfaces. We supplemented the searches by reviewing references from each
relevant manuscript. The selection of data was determined subjectively
to be synthesized into this review. Institutional review board approval
was not required for this study.
