To prevent the spread of COVID-19, the Centers for Disease Control and Prevention (CDC) now recommends that Americans wear wearing cloth masks in public settings where other social distancing measures are difficult to maintain. The CDC considers cloth masks an additional, voluntary public health measure.

On the Mayo Clinic Q&A podcast, Dr. Gregory Poland, a Mayo Clinic COVID-19 expert, explains the difference between medical masking and public masking, and discusses the proper way to put a mask on and off to prevent the spread of disease.
