First seen Jan 30, 2026 · Last updated Apr 30, 2026 · Updated 14 times
Summary
This early-phase study tested whether common mouthwashes can reduce the amount of SARS-CoV-2 virus that people with COVID-19 breathe out. 34 adults with a recent positive test provided breath samples using a face mask before and after rinsing with mouthwash or water. The goal was to see if mouthwash could lower viral particles in exhaled air, which might help reduce transmission.
