As the world waits for a vaccine to COVID-19, a new study finds there may be a way to slow the spread sitting right in your own medicine cabinet.
Researchers from Penn State College of Medicine say nasal and oral rinses like mouthwash can deactivate human coronaviruses. Their study finds these common, over-the-counter products should have the same effect on SARS-CoV-2, the virus causing COVID-19. The group tested various products including one-percent baby shampoo, a neti pot, peroxide sore-mouth cleansers, and mouthwash, seeing how each would lower the viral load of coronavirus strains in a patient's mouth. Researchers hope they may also lower the chances of COVID infection among people carrying the virus.
Their findings reveal most of these products effectively shut down virus particles in less than two minutes. Turns out that mouthwash and gargling products leave 99.9 percent of coronaviruses inactive after just 30 seconds. Some of these rinses stopped 99.99 percent of coronavirus. Researchers will now be looking to expand their study to clinical trials involving COVID-19-positive patients.
