• New research has shown that the most effective homemade face masks are those that are made of tightly-woven fabric and provide a good edge seal.
No effective gangs have been found.
• N95 masks must be installed correctly and must be reserved for those who need them.
Surgical masks are another effective option in areas where they are readily available.
Since the start of the COVID-19 pandemic, health agencies in the United States have recommended the use of a face mask to reduce the spread of the new coronavirus.
Since there is not enough medical-grade personal protective equipment to roam around, many Americans sew their own cloth masks or just wear a scarf.
While some levels of protection are understood to be better than nothing, there isn’t much information on the effectiveness of these homemade masks.
A new study, published today in the scientific journal Physics of Fluids from AIP Publishing, sheds new light on how to mask construction materials affect their effectiveness.
Siddhartha Verma, PhD, PhD, explained that “all major health agencies have now issued recommendations to the general public to use some form of facial covering, but there are no clear guidelines on the types of materials or designs that should be used.” The lead author who also works as an assistant professor in the Department of Oceans and Mechanical Engineering at the University of Florida Atlantic College of Engineering and Computer Science.
“Although there are few previous studies on the effectiveness of medical equipment, we do not have much information on the textile covers that are available at this time, because medical supplies need to be reserved. For healthcare workers,” Verma told Healthline.
Wear the mask 101
Dr. Teresa Amato, director of emergency medicine for geriatrics at Northwell Health, Healthline, said that even when experts struggle to understand an unprecedented pandemic 6 months ago, wearing a mask is not difficult in terms of reducing transmission.
“This is especially true with the increase in the number of people wearing a mask,” he said. “If you are infected while wearing a mask, it reduces the chance of infection. You use it to protect people around you while also using it to protect yourself from getting it. It is really important to emphasize that more people wearing masks will reduce transportation in general”.
When it comes to specific masks, you can go from a simple folded scarf to hand-stitched fabric masks and breathable N95 masks.
While N95 masks provide a high level of protection, they are not a realistic option for most people, as they should be dedicated to front-line workers. Amato also points out that it is not a one-size-fits-all option.
She said, “N95 skins must be installed, and users must be tested to make sure they are present correctly.” “Otherwise, wearing one is not really helpful. So we are not talking about the N95, we are talking about surgical masks or cloth.”
Fermat and his team tried to figure out which masks, in addition to N95, would be most effective.
He said that the simplest masks, be it a bandana band or a bandana, were practically ineffective.
He said, “I was a little surprised when I saw the number of leaks that could pass through the folded napkin rings and masks we tested, even through multiple folds of cotton cloth.”
Finally, Fermat and his colleagues decided that the most effective household masks are those that are well equipped with multiple layers of padded fabric.
The conical masks also worked well.
“The quilted stitch, with two layers together, turned out to be the best for stopping capacity,” said Fermat. “To reduce the chances of transmission, it’s important to use masks made of good-quality, well-woven fabric, as well as mask designs that provide a good seal along the edges without being awkward.”
Another beneficial option for a mask, says Amato, for those who can get it, are simple surgical masks.
She said, “Initially, we were attached to healthcare workers, but now we have a good supply of them.” “They are probably the most comfortable to wear. They are very light and offer good protection.”
Physical exclusion remains crucial.
Even the most effective face masks are not the whole and the whole in terms of avoiding transmission.
“It is important to understand that facial covers are not 100 percent effective in preventing respiratory pathogens, and for this reason, we need to use a combination of social spacing, facial covering, hand washing, and other recommendations from health care officials. until an effective vaccine is released, “he said. Fermat
Amato agrees, adding that it is important to consider the most dangerous transmission scenarios, primarily large-scale meetings in an enclosed space.
Some interactions, like yelling and singing, also have the ability to extend spray drops beyond 6 feet.
Amato said: “Reducing reactions is really how we will stop proliferation and return to normal faster.” “If you observe elevation areas, you can often trace practices like sitting in a bar without wearing a mask.”
Fermat concludes with the hope that this research will help inform people of best practices for wearing a mask.
He explained: “We have witnessed a certain aversion to the use of face masks, and we hope that the study will help clarify that the use of masks is primarily an attempt to protect the most vulnerable people in our society: the elderly or people with medical conditions. underlying health. ” “This is critical since current estimates indicate that 1 in 3 people are infected without public symptoms, and can unintentionally infect such vulnerable people.”
