Should you wear a face mask to prevent COVID-19? Experts disagree.

The public doesn’t need to wear heavy-duty respirators, but it’s a smart idea to don a face mask or wrap a clean scarf around your nose and mouth if you’re going into a crowded place during the COVID-19 outbreak, an infectious disease doctor told Live Science.

This advice on face masks (also known as surgical masks) goes against recommendations from the Centers for Disease Control and Prevention (CDC), which say that people who are not sick do not need to wear face masks unless they are caring for someone who is ill with the new coronavirus. It also goes against the advice of other infectious disease doctors Live Science interviewed.
