NIH director explains 'confusing' mask policy amid new coronavirus data

Francis S. Collins, director of the National Institutes of Health, joins Yahoo News Senior Political Correspondent Jon Ward on “The Long Game” podcast to discuss why guidance for wearing nonmedical face masks changed as officials learned more about how the coronavirus spreads. Collins points to early messages from Surgeon General Jerome Adams for civilians to stop buying N95 masks, which were needed by medical professionals, as a source of confusion but explains that the nonmedical masks now recommended serve a different purpose.
