Japanese supercomputer simulations showed that wearing two masks gave limited benefit in blocking viral spread compared with one properly fitted mask.

The findings in part contradict recent recommendations from the U.S. Centers of Disease Control and Prevention that two masks were better than one at reducing a person’s exposure to the coronavirus.

Using a single surgical-type mask, made of non-woven material, had 85% effectiveness in blocking particles when worn tightly around the nose and face. Adding a polyurethane mask on top boosted the effectiveness to just 89%. “The performance of double masking simply does not add up,” wrote the researchers, led by Makoto Tsubokura.

It is a fact that facemasks don't protect you from getting infected and instead mildly prevent that infected people will spread the virus if you are afraid of getting infected just stay at home that's the only effective way to prevent infections

I read the original article and in it said that the lead researcher emphasized the importance of wearing a mask without spaces/leakages around the nose. This article is missing the most important message.

There is no big difference between 'well fitted' mask and double mask. You don't have to make it double or more, just fit it better.

Interesting

THIS IS WHAT THEY SAID IN THE REPORT. Using a single surgical-type mask, made of non-woven material, had 85% effectiveness in blocking particles when worn tightly around the nose and face. Adding a polyurethane mask on top boosted the effectiveness to just 89%.

Recently my friend's baby was diagnosed with acute lymphocytic leukemia & needs a stem cell transplant. Jason & his wife are first-time parents caring for a sick baby & could use some help. If you are in a place to donate or share, it would be appreciated.

Sorry, it looks like it’s 20% better

vitormori

I cant breathe

At the beginning of the pandemic, all the 'experts' said that mask do very little to stop you from catching the virus, remember?! I guess the 'supercomputer experts' might overestimate the capabilities of their tool!

The tittle of the article is misleading. The test compares tight woven v loose woven v two non-woven masks. Reuter has to correct the error to avoid misinformation spreading.

Ahhhhhhhahahahahaha! TOLD YA, B!TCHES! DUMB SS LIBERALS! HYPOCRITES!

So basically wearing a well fitted mask collects 81% of droplets i.e. it helps a lot to wear a mask and to double mask helps even more. The way they worded this title is not very responsible, it’ll make the layman out there misquote it and spread false info.

Don’t mention it, because Americans are not even putting one 🙄

Tweeting of masks, has President Biden invoked the Emergency Powers Act, so to increase our production of N95 masks which actually will protect the wearer from inhaling airborne viral particles? If not, why not? The US should maintain a billion mask stockpile, vaccines or not.

Stupid japanese computer

How do real virologists work.

The chart shows bigger gains than the article reports oddly. 81 to 89% efficacy is a substantial jump for little extra effort. It would mean saving millions of people from contracting covid if followed. Anyways I’m not sure computer modeling is as sound as real-life testing.

But conveniently offers double the virtue signal and in some cases triple the sass.

I am not sure what diminishing returns accomplishes when a quarter of North Americans would rather die or commit treason than wear even one mask.

Çift maske kullanımı az miktarda işleve sahipmiş, ayrıca şimdilik en koruyucu maske N95 olarak belirtiliyor, sırasıyla; tek kullanımlık maskeler ve kumaş maskeler. (Not: poliüretanı maskeden saymıyorum.)

Wear two masks people. Japan was one of the first countries who refused to take the seriousness of the virus into account with the Diamond Princess. Let's stick to being overly cautious.

saitomri “…when worn tightly around the nose and face”

That Japan supercomputer also told them not to fear Godzilla...F that.

Little help, true, every little count, also true!

let us breathe in SCUBA tanks (covid free air). we all walk carrying the tanks like we are going for a dive.

Tripple masks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

'follow the science'

I didn’t think double masking actually did much either, but I do think you are less likely to take off two masks instead of just one. So if you wear your masks for longer periods of time, you form the habit, you start noticing when your not wearing one, etc.

... This isn't Chernobyl it's also Fukushima, Fukushima society is prey to itself by Implosion

You had me at “Japan” 😍

Today is 5th March 2021 We are stilling talking about the masks. 🙄

So all along Dr. Fauci is clowning 🤡?

No way, the “experts” are wrong again?

so idle you guys, just put your mask on, okay?

I am looking for new, good friends

So fauci lied?

He has proven that he's genuine, and i can trust him with my last dime that's what i want for you all as well invest with kellybrian_ 🙏🏻🙏🏻,

A mask works ! this is a known fact If a Mask leaks more than 15% in first place it cant be a mask For this common sense a super computer

Not an accurate summary of the study's results. The chart clearly shows a measurable (but not large) 8% gain in droplet collection efficiency. Study did not seem to address potential benefit of reducing air flow speed w/ 2 masks which could have spread reducing benefits.

.. PEOPLE must demand RESPECT and AUTONOMY. I REPEAT self-sufficiency respect and autonomy. There is excessive electromagnetic exposure, and toxic metals those responsible have to be judged

One that fits is always good, but most people don’t know if the mask really fits ... So if you put two of them it is still 20 percent more “safety” than with a wrong sized one.

Another point guys/gals, how about all the extra landfill that we are going to take up by using disposables at the rate we're using them?

Twitter! Please shut down this fake news. People are dying. How’s not the time for shit like this.

This is bullshit. Why polyurethane for the outer layer, and not 2 ply cotton or mixed fabric? Why not test with a mask brace holding both layers tight to the face. Common sense says five layers, tightly fitted, are better. Whether it's 15% or 1%, who the fuck cares. It's better.

Honestly, I'll wait for the practical/observational studies.

Did they input incorrect formula into super computer.

Japan supercomputer sounds like a witch, let's throw it in a river and see if it floats. TheDimAge

OK let's put it another way. If you have an algorithm that profits you at an 85% win rate are you saying you don't think improving the algorithm to an 89% win rate is worth it? ANYONE who says they wouldn't go for the upgrade is not being honest.

Ehhh. A simulation is only as good as the model.

me trying to read graphs in languages I don't understand and then having an opinion about it

Triple mask is the way.

I wore both a K95 and BYD aqua blue mask today at the workplace. It's tight on the ear hooks. Breathabilty isn't much different with a single mask. The masks helps encourage blood concentration to the head. Like a hat which keeps overflow and blood clots in cognitive core.

Did you try doubling make and kill the poor?

Sure Japanese super computer..... they don’t know what that is..... dumb computer is so dumb does not use common sense...

whether it's 1 or 2, just wear a fucking mask & this can be gotten under control in as little as 4 weeks Amid COVID-19 pandemic, flu has disappeared in the US

Everyone in the comments is an expert

It shows urethane fit masks are very efficient

Wonder how all the Democrats touting the “science” feel about this one?

This tweet will be deleted AutoCensor in 5-4-3-2-1

Don’t show this to the liberals wearing three or four

Inserting a word like supercomputer doesn't change the fact that input data is skewed by the humans with opinions that program them. Control condition biases resuscitated Schrodinger.

One mask offers little help in preventing viral spread. Don't need a supercomputer to work that out

The science is settled...lol. I bet you all just love reading that one! Also this, if you do 'double mask' make sure you're careful, the fibers from the disposables are horrible in your lungs.

IMPOSSIBLE FAUCI IS GOD!

What about quadruple masks

Why was Trump banned?

Well does Hal have any bright ideas to offer on its own as to how we stop this virus from spreading?

cc POTUS

I will always tell you about kellybrian_ he's one in a million I make money from home despite the world pandemic inbox him to know more about his crypto trade offers / 🙏🏻🙏🏻
