In an interview for 60 Minutes, CBS News chief medical correspondent Dr. Jon LaPook posed that question to Linsey Marr, a Virginia Tech University professor specializing in aerosol science.
“They are very helpful in reducing the chances that the person will get COVID because it’s reducing the amount of virus that you would inhale from the air around you,” Marr said about masks.
No mask is 100% effective. An N95, for example, is named as such because it is at least 95 percent efficient at blocking airborne particles when used properly. But even if a mask has an 80% efficiency, Marr said, it still offers meaningful protection.
“That greatly reduces the chance that I’m going to become infected,” Marr said.
Marr said research shows that high-quality masks can block particles that are the same size as those carrying the coronavirus. Masks work, Marr explained, as a filter, not as a sieve. Virus particles must weave around the layers of fibers, and as they do so, they may crash into those fibers and become trapped.
Marr likened it to running through a forest of trees. Walk slowly, and the surrounding is easy to navigate. But being forced through a forest at a high speed increases the likelihood of running into a tree.
“Masks, even cloth masks, do something,” she said.
Not that I expect most people to believe it at this point…
Yeah but a guy on YouTube said they don’t work and he said “trust me” so what now?
“you can still smell farts”
sigh
At the same time, you have the people claiming they immediately turn blue and pass out within seconds of putting a mask on.
Millions of people in this country apparently have problems keeping two thoughts in their head at the same time.
To these people, COVID is simultaneously not as bad as the flu, a Chinese hoax, something to be fought with ivermectin, a liberal hoax, something so infectious it can get through even the best fitted filtration mask, fought by going to the gym, fought by getting more sunlight, overblown in death count, etc etc.
Masks are the same. They’re simultaneously stifling and damaging to your health because they disallow O2 ingress or whatever and you can’t use them because you have some private health condition, and they’re completely ineffective at keeping out COVID somehow.
My diagnosis is that they’re brain wormed from the maga mind virus, and probably got some damage from COVID too.
Who probably also think that they are physically superior to others, while in reality have admitted to being pretty fucking pathetic if they can’t handle a mask for a few minutes let alone hours.
I’m not even worried about covid anymore but continue to mask in busy places in the fall/winter because it’s nice not being congested half the season, and it’s easy. And the fact that my mask doesn’t perfectly filter out virus particles is even better because my immune system still gets some exposure to do some local updates with.
