“Cloth masks are little more than facial decorations. There’s no place for them in light of Omicron,” said CNN Medical Analyst Dr. Leana Wen, an emergency physician and visiting professor of health policy and management at the George Washington University Milken Institute School of Public Health, on CNN Newsroom Tuesday.
“This is what scientists and public health officials have been saying for months, many months, in fact,” Wen added in a separate phone interview.
“We need to be wearing at least a three-ply surgical mask,” she said, which is also known as a disposable mask and can be found at most drugstores and some grocery and retail stores. “You can wear a cloth mask on top of that, but do not just wear a cloth mask alone.”
Ideally, in crowded places, “you should be wearing a KN95 or N95 mask,” which can be as inexpensive as a few dollars each, Wen added. By having a better fit and certain materials — such as polypropylene fibers — acting as both mechanical and electrostatic barriers, these masks better prevent tiny particles from getting into your nose or mouth and must be fitted to your face to function properly.
Changing guidance
During the first several months of the pandemic, health experts discouraged the general public from buying N95 masks, since medical professionals were facing a shortage of personal protection equipment. But it has “been many months since supply of N95s (has been) an issue,” Wen said.
Yet the US Centers for Disease Control and Prevention’s most recent guidance on selecting, properly wearing, cleaning and storing face masks recommended people avoid N95 masks and instead choose masks with two or more layers of washable, breathable fabric — which Wen called “a major mistake.”
“If we’re going to go as far as to say that masks are required — when we don’t come from a mask-wearing culture and people don’t like wearing masks — at least recommend that they wear the most effective mask,” Wen said.
