The New York Times recommends wearing two masks instead of one



The Centers for Disease Control and Prevention (CDC) stated that to prevent the spread of COVID-19, all Americans should wear masks.

The New York Times said that if one mask is effective, maybe two will be twice as good.

The football coach did. The president elected to do this. Even the science-savvy senators do the same. The paper writes that as coronavirus cases continue to surge globally, some of the country’s most prominent figures have begun to double the use of masks. Researchers say this move is increasingly supported by data.

The Times quoted Virginia Tech virus transmission expert Linsey Marr (Linsey Marr) as saying, “If you combine multiple layers, you will start to achieve a very high efficiency”

; to prevent the virus from coming out of the nose or mouth, or even entering them. .

Of course, there is a disadvantage: “We risk breathing difficulties.”

The CDC stated that COVID-19 “is mainly spread from person to person through respiratory droplets. When you cough, sneeze, speak, shout or sing, respiratory droplets will fly into the air. These droplets will then land on you People nearby may inhale these drops in the mouth or nose.”

The federal agency now says: “Cloth masks also provide you with some protection. How it protects you from the breathing of the virus may depend on the fabric used and the way the mask is made (for example, the type of fabric, the number of layers of the fabric, the mask The degree of fit). CDC is currently studying these factors” and said that more evaluation is needed.

The CDC still stated: “Research shows that cloth mask materials can also filter through, including filtering small droplets and particles smaller than 10 microns, reducing the wearer’s chances of contact with infectious droplets. Throughout the study, the relative filtration of various masks The effect is very different, which is largely due to the experimental design and the changes in the analyzed particle size.”

The Times said that the best mask is still N95, which can filter out 95% of particles and liquid droplets. “Two less professional masks stacked on top of each other can provide comparable protection.”

“Dr. Marr recommends wearing a cloth mask close to the face mask on the surgical mask. This type of mask is often made of a filter-friendly material, but it is looser to wear. Another option is to wear a cloth mask with a mask. Masks can be filled with filter materials, such as those in a vacuum bag. However, wearing more than two masks or layering on a mask that is already very good at filtering will quickly bring diminishing returns and make normal breathing difficult. Much.

In October, President-elect Biden saw two masks wearing two masks. He went to the North Carolina campaign and used a cloth superstructure paper surgical mask.

The Daily Mail reported: “Biden was photographed wearing a white mask under a navy blue mask. A few days after his father’s email became national headlines, Hunt’s teenage daughter Finnegan (Finnegan) joined Biden.” “Finnegan seems to be wearing a white mask with a navy blue hidden on it and it says:’Vote’.”
