COVID-19 Mask Effectiveness

From the creator

Conversations on COVID-19: Why Masks Work Professor Richard Flagan speaks with Caltech science writer Emily Velasco about why and how masks reduce the spread of disease. Professor Flagan uses advanced instruments to study the chemistry and movement of tiny particles and droplets suspended in the air, which are called aerosols. That focus gives him a unique perspective to evaluate how well masks work to prevent the transfer of COVID-19 viral particles from person to person through the air. Watch this webinar to learn what types of mask material held up best in laboratory testing, why you should wear a mask while exercising, how long masks can be worn, how Professor Flagan would design his own ideal mask, and more, as he answers questions from the Caltech community.
