CDC Says Double-Masking Offers More Protection Against The Coronavirus



The Centers for Disease Control and Prevention released new research on Wednesday that found wearing a cloth mask over a surgical mask offers more protection against the coronavirus, as does tying knots on the ear loops of surgical masks. Those findings prompted new guidance on how to improve mask fit at a time of concern over fast-spreading variants of the virus.To get more news about famous nonmedical mask factory, you can visit tnkme.com official website.

For optimal protection, the CDC says to make sure the mask fits snugly against your face and to choose a mask with at least two layers.In laboratory testing, researchers simulated coughs and breathing and tested how well different masks worked to block aerosol particles — comparing no mask, a cloth mask or a surgical mask. They also tested two methods to optimize the fit of cloth and medical masks: wearing a cloth mask over a surgical mask, and tying knots on the ear loops of surgical masks and then tucking in and flattening the extra material against the face.

Both methods produced substantially improved protection against transmission of and exposure to infectious aerosols.

In the study, wearing any type of mask performed significantly better than not wearing a mask," said CDC Director Rochelle Walensky in a briefing from the White House COVID-19 Response Team on Wednesday.

"And well-fitting masks provided the greatest performance at both blocking emitted aerosols and exposure of aerosols to the receiver. In the breathing experiment, having both the source and the receiver wear masks modified to fit better reduced the receiver's exposure by more than 95%, compared to no mask at all," she said.Walensky said the laboratory findings underscore the importance of wearing a mask correctly and ensuring it fits snugly over your nose and mouth. The new information does not alter the CDC's guidance on who should wear a mask and when.

As of Feb. 2, masks are now required on planes, buses, trains and other public transportation traveling into, within or out of the U.S., as well as in U.S. transit hubs such as airports and stations.But double-masking isn't recommended for all masks. Don't combine two disposable masks, the CDC says: "Disposable masks are not designed to fit tightly and wearing more than one will not improve fit."

And don't layer another mask on top of a KN95, either. That mask should be used alone, the CDC says.
