The Centers for Disease Control and Prevention (CDC) states that to stop the spread of COVID-19, all Americans should wear a mask.
The New York Times says that if one mask works, it might be twice as good.
“Football coaches do it, the president – voters do it. Even a senator who specializes in science does. As cases of coronavirus continue to rise globally, some of the country’s most famous people are beginning to double as masks, a move that researchers say is increasingly backed up. Do not “write documents
The Times quoted Linsey Marr, a viral infection expert at Virginia Tech, who said, “If you combine layers, you start to get very effective at blocking the virus from escaping or even entering your nose or mouth.
Of course, there is a downside: “We risk making it too difficult to breathe.”;
The CDC states that COVID-19 is spread “mostly from person to person through respiratory droplets. Respiratory droplets travel through the air when you cough, sneeze, talk, shout, or sing. These drops can then fall into the mouth or nose of someone close to you, or they can breathe in the aerosol. ”
And now, the federal agency says, “The cloth mask will also give you protection. How well you can prevent breathing in the virus depends on the fabric used and the method of making your mask. (Eg type of fabric, number of layers of mask fabric, how well it is) CDC is studying these factors. And said further assessments were needed.
Still, the CDC announced, “Studies have shown that fabric mask materials can also reduce the wearer’s exposure to infectious aerosols through filtering, as well as filtering fine droplets and particles smaller than 10 microns. The relative filtration of the various masks varied greatly in studies, mainly due to differences in the experimental design and the size of the analyzed particles. ”
While the Times says the best mask is still N95, which filters 95% of particles and water droplets, “placing two less special masks on top of each other can provide equivalent protection.
“Dr. Marr recommends wearing masks, face masks, surgical masks, which are often made with a more filter-friendly material. But will be looser Another option is to wear a cloth mask with a bag that can be stuffed with filter material, just like a vacuum bag. But wearing more than two masks or overlaid on an already well filtered mask will dramatically decrease yields and make breathing more difficult as usual, ”the document states.
In October, President-elect Joe Biden wore two masks as he traveled to North Carolina to halt the campaign using a cloth to wear a paper mask.
“Biden, photographed wearing a white mask in a navy blue dress with Hunter’s teenage daughter Finnegan, just days after her father’s email made national headlines,” said the Daily Mail. Report: Finnegan appears to be wearing a white mask under navy blue which reads ‘vote’.
