Virologists from Ruhr-Universität Bochum together with colleagues from Jena, Ulm, Duisburg-Essen, Nuremberg and Bremen has done research and claimed high viral loads can be detected in the oral cavity and throat of some Covid-19 patients.
In a recent study published in the Journal of Infectious Diseases, says that
gargling with commercially available mouthwashes reduce the quantities of viral load in the mouth and throat, and possibly reduce the risk of covid-19
Researchers tested the effects of eight mouthwashes that are available in pharmacies or drugstores in Germany. Interestingly viral load was found reduced in all the test mixtures (ones with the mouthwash) and some even had almost no virus after 30 seconds.
Gargling with mouthwash cannot inhibit the production of viruses in the cells, but could reduce the transmission. Where the greatest potential for infection comes from, namely in the oral cavity and throat said study co-author Toni Meister from Ruhr University Bochum.
Researchers at the Ruhr-University Bochum are now planning to do clinical studies to assess whether the same effects are seen in patients and for long do the effects last
