Conclusion
throat
The present study indicates that gargling mouth and throat with a commercial mouthwash
containing 0.05% CPC and 0.05% CHX could slightly but significantly reduce viral load in
SARS-CoV-2–positive patients. Despite a small sample size, the test mouthwash also
significantly reduced viral infectivity, while notably, gargling with 0.9% NaCl also had a
slight effect. These findings add some further evidence for a potential effect of
CPC-containing mouthwashes on reducing SARS-CoV-2 infectivity, although further studies with
larger sample sizes are needed to corroborate these results.
