Which face covering is most effective in slowing the spread of the coronavirus? Maybe the leggings. Alarmist stories are circulating about how those tissue tubes worn on the face offer no coverage against the spread of the coronavirus, a study published in Science Advances by Duke University researchers shows, but according to the study authors Those reports do tell the whole story.
Researchers sought to create and verify an approach to compare the effectiveness of facial coating types, from the N95 mask to handkerchiefs, to prevent the spread of respiratory droplets in the air. Current studies suggest that coronavirus spreads through those respiratory droplets, which we expel.when we talk, we scream, sneeze, cough or sing.
They tried another 14 facial coatings in total, the maximum of which were fabric masks, like the ones you can buy virtually anywhere at this time. They also tried a fleece neck mask and a handkerchief. The effects of their tests show that the scarf and fleece transmit as many or more respiratory droplets as dressed in any type of face mask.
However, researchers say these effects deserve not to be extrapolated to all neck scarves and masks.Dr. Martin Fischer, one of the authors of the study, told CNET: “Our paintings have focused on developing a strategy that can be replicated in other laboratories, which in a full mask test.As we indicated in the article, our paintings were an initial examination that included only a fleece mask (also called a leg mask or neck mask); we didn’t do a systematic examination with many masks, speakers and conditions of use.More studies are needed to make explicit use recommendations.”
In reaction to the Duke study, a team of Virginia Tech researchers tested two types of neck masks to see how effective they were at containing respiratory droplets: one consisted of an unmarried polyester layer and the other, made of polyester. and elastane, used two layers of fabric. They found that either it had a point of coverage similar to that of the typical fabric mask, the two layer mask was more effective.
Neck masks have a popular face mask, as they can be used in other tactics and regularly do not shoot your ears like a mask. Prior to the pandemic, they were regularly used to protect their face and neck from disbelievers or to remove sweat from Many of them consist of a solitary layer of thin tissue and were not originally designed to block respiratory droplets or slow the spread of viruses.
For this explanation, Dr. Fischer says they would probably not be as protective as other types of cloth masks.”The fleece mask we present is a polyester/elastane mask.As a general rule, those masks are thin enough to provide breathability, which is probably the explanation for why so many debris forms, damaged into smaller pieces,” he said.However, we expect that there will be diversifications in functionality for other masks (even of the same type) and other users dressed in the same mask.”
Since there are other types of neck masks made from a variety of other fabrics, we say that not all neck covers slow down the spread of the coronavirus or are worse than not dressing with a face layer.
More studies are needed before we can definitively determine which types of non-medical face coverings are the most productive to prevent the spread of coronavirus We know that N95 respiratory masks are among the most protective, but those masks are reserved only for fitness professionals.For the rest of us, reusable fabric masks are lately the ultimate productive option we have, and at least according to some fitness authorities, this includes the neck mask.
