Say it, don't spray it.
Can we Sue these people that make us wear these masks when all the Eye Nose Throat and Lung problems start ?
And the lint into your lungs.
So if the are worn correctly the masks decrease the aerosolized particles released. Does this reduce the spread of infection or is whats left more than adequate to spread it. What about the masks worn incorrectly. Did they test masks after 20 minutes of use or longer? How about masks worn over and over again? Ill ef the results are very different
So this study couldn’t distinguish between particles and droplets?
Deadly cotton fibers.
Obama/Biden Just in time supply chain almost destroyed us.
See Battelles machines are capable of cleaning 80,000 M-95 masks per day, and Ohio has two of these machines, located in Columbus and Beavercreek. USA innovation !!!
Everyone seems to miss the most important point: that someone who doesn’t have the coronavirus, which is most people, isn’t going to get anyone sick, regardless of who does or doesn’t wear a damned mask. This whole hysteria is just unbelievable.
N95 masks stop viruses like screen doors on submarines stop water.
Well I suppose someone needed to research this scientifically.
But some things are just self evident. Everyone has always known to stay away from people with viral infections like the flu or covid. Trouble is, sometimes these are asymptomatic or presymptomatic.
If you have a transmissible virus wearing the mask probably does help, to some degree, prevent spittle from spraying onto others.
But as the article alludes, there are 2nd order effects to consider. If you keep wearing the same mask, unwashed for days on end, you will touch it many times and then you will get your fingers onto other surfaces and other people. There seems to be scant evidence that wearing a mask stops you from catching a virus, as there is showing it may prevent someone from spreading it.
If someone with covid spittles on your mask, you may not breathe it in. Though, who has tested the molecule size and what types of masks filter down to the appropriate nanoparticle size etc? And then, assuming they didn’t get it in your eyes, it’s still on the surface of your mask... for how long, how many times you touch it, how long does it last on surfaces... all open questions in my book.
Wash and/or change out your masks. Sanitize your hands. Wash your hands a lot with soap and hot water for 20 seconds. The media loves to harp on the “wear a mask” part of it, but skimp out on the rest especially the part about changing and cleaning masks. People all over just keep the same mask in their car, wear it when they exit the car, take it off when they drive, and never clean it for weeks.
I sewed our masks out of a lightweight gauze fabric.
How many particles do you suppose they block?
:-)
Dontcha just love articles about slave muzzles?
Getting more Fiber is a Bad Thing?
Do not block viruses
Abstract: There were 3 influenza pandemics in the 20th century, and there has been 1 so far in the 21st century. Local, national, and international health authorities regularly update their plans for mitigating the next influenza pandemic in light of the latest available evidence on the effectiveness of various control measures in reducing transmission. Here, we review the evidence base on the effectiveness of nonpharmaceutical personal protective measures and environmental hygiene measures in nonhealthcare settings and discuss their potential inclusion in pandemic plans. Although mechanistic studies support the potential effect of hand hygiene or face masks, evidence from 14 randomized controlled trials of these measures did not support a substantial effect on transmission of laboratory-confirmed influenza. We similarly found limited evidence on the effectiveness of improved hygiene and environmental cleaning. We identified several major knowledge gaps requiring further research, most fundamentally an improved characterization of the modes of person-to-person transmission.
Symbolism over substance, someone likes to say.
