Masks are actually amazing, because they work immediately — they start reducing transmission today. Every case they prevent prevents several other cases, so their effectiveness grows over time. — Julia Raifman, an assistant professor at Boston University’s School of Public Health

If you allow the virus to freely circulate and not try and stop it, sooner or later there is a likelihood that you will get another variant that could, I’m not saying it will, but could be more problematic than the Delta. — Dr. Anthony Fauci, the nation’s top infectious disease expert

At the end of the day, the C.D.C. is a science agency that responds to politicians. If you’re indoors, you should wear a mask. — Dr. Carlos del Rio, an infectious disease specialist at the Emory University School of Medicine in Atlanta

Why Not Just Tell Everyone to Wear Masks?
The C.D.C.’s advice about masking up again was not easy to parse. Some experts think simpler would have been better.

... “The messaging from the C.D.C. was less than optimal,” said Dr. Ezekiel Emanuel, vice president for global initiatives at the University of Pennsylvania. “We need to be clear and relatively simple about it.”

... In many communities, mandates are gaining traction, and already the nuances about transmission rates and underlying conditions have been left aside. It’s easy to see why: As of Tuesday, the virus was spreading rapidly in 90 percent of U.S. counties. And masking is swiftly effective.

Masks “are actually amazing, because they work immediately — they start reducing transmission today,” said Julia Raifman, an assistant professor at Boston University’s School of Public Health. “Every case they prevent prevents several other cases, so their effectiveness grows over time.”

Wearing a mask also helps protect children who can’t be vaccinated yet, and others who are susceptible, like the elderly and those with compromised immune systems, who may not be able to mount a vigorous immune response following vaccination.

Masking also helps to prevent the virus from circulating, reducing the chances that it will mutate, possibly into a form more virulent that may evade vaccines altogether.

“If you allow the virus to freely circulate and not try and stop it, sooner or later there is a likelihood that you will get another variant that could, I’m not saying it will, but could be more problematic than the Delta,” Dr. Anthony Fauci, the nation’s top infectious disease expert, said Sunday on NBC’s “Meet the Press.”

... By setting localized benchmarks, the agency’s mask recommendation “gives everyone something to look forward to,” said Dr. Carlos del Rio, an infectious disease specialist at the Emory University School of Medicine in Atlanta. “At the end of the day, the C.D.C. is a science agency that responds to politicians.”

Still, he added: “If you’re indoors, you should wear a mask.”
