What do coronavirus variants mean for your masks?

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said that when it comes to wearing two masks to protect against the coronavirus, it “makes common sense” that more than one layer of masking would be more effective.There is no specific research on how well face coverings work against new variants of the virus, including the more transmissible variant from the United Kingdom that has been detected in at least 22 states in the United States. Asked at a White House briefing last week whether the new variant would make masks less effective, he said that on the contrary, the variants are “the reason why you absolutely should be wearing a mask.” “If that wasn’t plainly obvious six months ago, it surely is now,” said Cameron Wolfe, an infectious diseases expert and an associate professor of medicine at the Duke University School of Medicine.
