Americans should be wearing N95 masks for greater protection against the highly contagious COVID-19 Delta variant, according to Dr. Scott Gottlieb, former head of the Food and Drug Administration (FDA).
Gottlieb told CBS News’s “Face the Nation” on Sunday that the quality of a mask matters in protecting against the strain, which was first identified in India in late 2020, and currently makes up approximately 83 percent of all new sequenced COVID-19 cases in the United States, according to federal officials.
