Wearing two masks to protect against the virus is that better?

Wearing two masks to protect against the virus is that better?

Dr. Anthony Fauchi, director of the National Institute of Allergy and Infectious Diseases in America, said that although there is no formal recommendation on the double mask, this may be the "common approach."

 

"There is no recommendation" to wear a double mask, Fauchi said, but noted that "there are a lot of people who take a common approach."

 

"If you're talking about a physical barrier, and as the Centers for Disease Control and Prevention (CDC) recommends, you want at least two layers inside the mask as a physical barrier, then you feel it would be better to have a physical barrier, so there's nothing wrong with someone wearing masks" . Fauchi said he often wears two masks.

 

"Can we make a general recommendation that has no scientific basis yet? No, but when science comes and tells us it's better or not, you'll see a recommendation from the CDC."

 

Dr. Rochelle Wallensky, director of the U.S. Centers for Disease Control and Prevention, said the CDC is currently conducting a scientific assessment and is considering its recommendations on the double mask based on the latest science."

 

Studies have shown that the monolayer mask is not effective in preventing the wearer from spraying, even two- and three-layer cloth masks are only partially protective, somewhere at 50% to 60% effectiveness.

 

A 2020 study found that surgical masks were 50% effective in protecting wearers and about 60% to 70% in protecting others. But if you put a surgical mask under the cloth mask, experts believe it is more than 90% effective in removing particles.
