Public health officials are suggesting double masking as a way to increase the level of protection from the coronavirus and its multiple, more contagious variants.
"If you have a physical covering with one layer, you put another layer on, it just makes common sense that it likely would be more effective, and that's the reason why you see people either double masking or doing a version of an N95," Dr. Anthony Fauci, now chief medical adviser to President Joe Biden, told NBC's Savannah Guthrie.
