Eighteen months into the COVID-19 pandemic, as COVID-19 variants spread and the pandemic persists around the world, there are a lot of questions about masking. When do I need to wear a mask? Where do I need to wear a mask? Is masking still needed if I’m vaccinated?

No single intervention alone is sufficient to end the pandemic, but face-covering has become increasingly important as lockdowns are eased and people seek a full return to public life. By wearing a mask in public indoor and crowded places, everyone can help slow the spread of COVID-19 and save lives. Ending mask requirements too soon will unnecessarily cost many lives.
