    Face Coverings for COVID-19 Not Effective When Air Quality Unhealthy

    The cloth face coverings and surgical masks that you wear to help reduce the spread of COVID-19 don’t protect you against the unhealthy air conditions now impacting much of the Bay Area.

    The smoke and particles in the air from the wildfires can irritate your lungs and cause inflammation which impacts your immune system and makes you more prone to lung infections including SARS-CoV-2, the virus that causes COVID-19.

    One of the best ways to protect against the potentially harmful effects of wildfire smoke is to limit your time outside. See additional waysto protect yourself during wildfire activity at
