Mouthwash Could Reduce SARS-CoV-2 Short-Term Viral Load, Cell Culture Study Suggestshttps://www.technologynetworks.com/immunology/news/mouthwash-could-reduce-sars-cov-2-short-term-viral-load-cell-culture-study-suggests-338460
TL;DR – A clinical trial is under way following cell culture experiments that suggest that some mouthwashes can reduce the amount of viral shedding from breathing. It isn’t a cure for COVID-19 but a way to reduce your viral load that you’d normally expel in your breath if you were unlucky enough to be infected.
The names of the mouthwashes seem to be omitted, but I’ll do a bit of research and see what I can find.
(At this stage I’m aware that most mouthwashes use cetylpyridinium chloride and a smaller subset use chlorhexidine, possibly the criterion for reducing “virusbreath” might which one of these the mouthwash uses.)
