I heard that mouthwash kills the coronavirus! How often should I gargle?

Uncertainty and Misinformation

A. TL,DR: Mouthwash won’t prevent or cure COVID-19. Consistent with several prior studies, a recent laboratory-based study out of Cardiff University found that over-the-counter mouthwash (with active ingredient cetylpyridinium chloride [CPC]) will inactivate 90-99% of the coronavirus after a mere 30 seconds. Sounds exciting! …but don’t get your hopes up. The clinical relevance of mouthwash Read more…

If I already recovered from Covid-19 infection, can I be sure I won’t get it again or pass it to others?

Biology/Immunity Infection and Spread

A: No. Evidence on the longevity and strength of the immune system response to SARS-CoV-2 remains inconclusive. Previous infection does not give you an “immunity passport”. All individuals should continue to follow SMART precautions, particularly during the holiday season. Here is what we know to date. Antibody testing alone is an insufficient measure of immunity.

Is it true that some people already have antibodies to SARS-CoV-2 from previous exposure to seasonal coronaviruses?

Biology/Immunity

A: Maybe; there *is* evidence of antibodies to seasonal coronaviruses reacting to some parts of the SARS-CoV-2 virus. BUT so far there is no solid evidence that these antibodies protect from COVID-19 infection or disease. What does it mean to have “cross-reactive” antibodies?
