Answers to your DIY face mask questions, including what material you should use

Answers To Your DIY Face Mask Questions, İncluding What Material You Should Use


On April 3, U.S. health officials recommended an arts and crafts project to U.S. residents: Make a cloth mask, then wear it when you go out in public.
Covering your mouth and nose is one more thing people can do in addition to social distancing and hand-washing to slow the spread of the novel coronavirus, according to the Centers for Disease Control and Prevention. Medical-grade masks are scarce and should be reserved for front-line health-care workers who are repeatedly exposed to huge amounts of the virus.
But a DIY face cover offers a bit of protection to the wearer while helping prevent them from unknowingly spreading the virus to others, a useful thing when up to a quarter of people who have covid-19 may show no symptoms, according to the CDC.

I’m İn. What Material Should I Use?

The coronavirus is extremely tiny too tiny to be trapped by most fabrics that still allow air to flow through them.
However, the virus seems to be most transmissible when it is stuck to much larger water or mucus droplets that come out of our mouths and noses when we cough, sneeze or talk, and a homemade mask can block those droplets.
As the mask needs to be made of something you already have around the house, cotton seems to be a good choice. The CDC recommends two layers of tightly woven 100 percent cotton fabric, such as quilter’s material or bedsheets with a high thread count.
A group of scientists and doctors at Wake Forest University tested different masks made by community volunteers and found two of the better options to be a double layer of cotton with a thread count of at least 180, and a double layer of normal cotton with a layer of flannel in between.
Speaking of layers, don’t just pile them on. You need to strike a balance between breathability and filtration.
Make sure you can breathe comfortably through your nose while wearing the mask sticky nose hairs can catch some particles as well before they travel deeper into your respiratory tract. If the mask isn’t porous enough, you will be breathing around the sides of it rather than through it.
Vacuum bags, for instance, can be tough to breathe through unless you are an actual vacuum. (And be careful some can contain fiberglass and other fibers that you do not want to inhale.)
A group of Cambridge University researchers compared filtration and breathability of different types of homemade mask materials, and here’s what they found. They concluded that masks made from pillowcases or a cotton T-shirts struck the best balance.


What Pattern Should I Use, And What İf I Can’t Sew?

There is no one design that is the consensus gold standard for a DIY mask. There are patterns floating around everywhere, and studies have shown that any face covering is better than nothing.
Here’s one created for The Post by Grace Jun, a professor of fashion at Parsons School of Design in consultation with health experts in New York.

The CDC website has a few patterns, including one that involves a coffee filter and another that requires no sewing  just scissors and the willingness to sacrifice a T-shirt. Surgeon General Jerome Adams released a video of himself making a mask out of cloth and rubber bands.
Whatever style you choose, make sure the mask fits well, covering your nose and chin.

Once you’ve got your new mask secured to your face, leave it on while you’re outside and don’t touch the front of it  just as you wouldn’t touch your face.


I Wore My Creation To The Store. Can I Take İt Off Now?

Yes, and you should. Once you’re back home after wearing your spiffy new mask in public, remove it without touching the front and without touching your eyes, nose or mouth.
You’ll want to clean it before wearing it again. You don’t need to wash your mask differently than other laundry because the soap in detergent should destroy any viruses.


Why Can’t I Just Buy a Surgical Mask or Respirator?

The CDC asks that those masks be saved for health care workers, who are exposed to a far higher dose of the virus than a person would encounter on a quick trip to the grocery store.
These two masks worn by health care workers offer very different types of protection.
The more exposure, the more likely a person is to get sick  and the level of exposure probably also plays a big role in the severity of the disease.
“I think dose is really important,” said Vineet Menachery, a virologist at the University of Texas Medical Branch in Galveston who specializes in studying coronaviruses. “The higher the dose you get, the more sick you are likely to get.”
A previous version of this story had a chart that incorrectly compared the size of the coronavirus to other particles.

Why COVID-19 makes a compelling case for the wider integration of blockchain

Why COVID-19 Makes A Compelling Case For The Wider İntegration Of Blockchain The COVID-19 crisis has revealed a general lack of connectivity and data exchange built into our global supply chains. Future resiliency will depend on building transparent, inter-operable and connective networks. When it became clear that many of us would soon be working from home, a majority took a cursory glance at their home office set-ups and decided it needed upgrading. What ensued was an unanticipated rush and surge of online orders for office desks, chairs, lamps and computer hardware. But such was the sudden spike that it has unsurprisingly caught suppliers large and small unprepared, off guard and exposed gaping holes in their ability to track purchases from one end of their supply chains to the other. Some customers, who have spent no small amount on revamping their home offices are still waiting to do so, without the consolation of being able to see where their orders are, or when they...

Covering the coronavirus pandemic: CNN correspondents reflect on how we got here

Covering the coronavirus pandemic: CNN correspondents reflect on how we got here Atlanta (CNN) As the entire world grapples with the effects of the coronavirus outbreak, it is easy to lose sight of how we got here. There are not many news events in recent memory that have come close to the far-reaching implications in terms of our public health, social interactions, and the global economy; life as we know it has been altered. From the beginning, CNN journalists have covered this unprecedented story from all corners of the globe. Three months since we heard the first whispers of a strange respiratory illness emerging in China, this is the story of a story  from those who have witnessed and reported on it firsthand. Wuhan: Ground Zero On the final day of 2019, the World Health Organization receives word of a pneumonia-like disease in the central Chinese city of Wuhan.

Coronavirus at meatpacking plants worse than first thought, USA TODAY investigation finds

Coronavirus at meatpacking plants worse than first thought, USA TODAY investigation finds Coronavirus closed Smithfield and JBS meatpacking plants. Many more are at risk. Operators may have to choose between worker health or meat in stores. Tyson Foods installed plastic barriers between worker stations at its meat and poultry plants to protect against transmission of the coronavirus. Arash of coronavirus outbreaks at dozens of meatpacking plants across the nation is far more extensive than previously thought, according to an exclusive review of cases by USA TODAY and the Midwest Center for Investigative Reporting.  And it could get worse. More than 150 of America’s largest meat processing plants operate in counties where the rate of coronavirus infection is already among the nation’s highest, based on the media outlets’ analysis of slaughterhouse locations and county-level COVID-19 infection rates. These facilities represent more than 1 in 3 of the nation’s...
