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...

So fucked up masks became politicized: I had hoped that the pandemic would help normalize them so people would just mask up whenever they feel sick. It could've mitigated the spread of all sorts of airborne disease.

Instead, they've been demonized by insane fascists. What a stupid world we live in...

Sometimes I just wear a mask to piss them off lol.

God I remember when this happened.

Right at the beginning of the pandemic, masks were being recommended by the CDC and everyone just sort of did it. COVID was novel and we were still trying to wrap our heads around it and being over cautious.

Weeks earlier, Trump was lamenting his polling numbers and complained that he didn't have a "Katrina" that would rally his favorables.

Trump could have done something simple and just worn the damn mask. He could have told people that until they had better data, let's be cautious and following the CDC guidelines.

But when he was asked point blank, he said he wouldn't wear one.

Before that, conservatives and liberals were wearing masks. It wasn't a "tribal" signal. But the second he said it, it was. You could tell immediately after that who conservatives were.

The funny thing is had Trump handled COVID better, he probably would have won re-election. Or at least it would have been closer.

But nope. That's not the kind of person he was.

He could have made a MAGA mask and told his cultists that it was more effective and blessed with holy water or something, and then go on to make piles of cash. At the time, that's what I was expecting to happen, but sadly I was wrong.

[-] CosmicTurtle@lemmy.world 8 points 1 year ago

There was so much happening around this time. There was a story that didn't get a lot of runtime about some company that he or someone who was connected to him set up where the federal government purchased masks bought a bunch of boxes from them but never got delivered.

The internal audit found that they basically the funds were misappropriated. The whole management of funds were so.....shady to say the least.

Unfortunately, the recommendations from most (all?) top-level officials in the US right at the beginning of the pandemic was for the general public NOT to wear masks (including Dr. Fauci, Dr. Birx, etc). This absolutely didn't help matters when later they had to change their tune and recommend then mandate masks, after they had said that they were not needed.

Here's a nice compilation video of these statements over the first couple of months of the pandemic: https://piped.video/watch?v=tRE59LJc6CA

This is not what happened, they recommended people not to wear masks at the start. This might have undermined their later recommendation to wear a mask

[-] RGB3x3@lemmy.world 3 points 1 year ago

This is true. They didn't want to cause a mad rush for N95s and other medical masks, because they knew medical professionals needed them more. Because then as soon as they recommended the masks, there was a huge shortage.

But some people took the changing recommendation as some kind of conspiracy, that the government is just making it all up.

He would have had more voters at least.

[-] Grumpy@sh.itjust.works 15 points 1 year ago

I'm Asian. So I could wear a mask and not get the stink eye even before covid.

Things that should become obviously acceptable often doesn't seem to do so due to some sort of cultural acceptance.

Like in regions most susceptible to malaria, they hate mosquito nets. Yet if I lived there, I'd mosquito net everything even without malaria!

[-] steltek@lemm.ee 4 points 1 year ago

They're normalized in some places. I see people wearing them and not just the "Covid isn't over!" folks.

[-] _haha_oh_wow_@sh.itjust.works 12 points 1 year ago

I mean, COVID isn't over lol: It didn't go anywhere, we're just dying from it a little less often. Must be nice avoiding colds and flu if masks are common in your area though, getting sick sucks.

Covid has reached a ubiquitous state where it's a constant presence around us. Similar to how cold and flu virus are. So in a sense, the high concern and detailed tracking is over. And we must simply accept that there is one more virus as part of our lives. It's not over in the sense that it's gone. That certainly will never be now.

[-] snooggums@kbin.social 4 points 1 year ago

It is over in the same way that the Spanish Flu is over, still around but not a massively infectious and deadly threat in the way it was originally due to vaccinations and herd immunity.

[-] Touching_Grass@lemmy.world 5 points 1 year ago

Which was what experts said from the start. Small chance it could get worse. But likely it'll become endemic? And when it does it'll just be like the cold. All we need to do is make sure we keep deaths low until it does by following some things like distancing and masking. Shut downs were terrible for many but it saved lives. Meanwhile everyone I knew kept telling me how they were lying about those steps and really it wouldn't be temporary it was ushring in a NWO under the WHO

Yes, it no longer impacts our comings and goings meaningfully anymore, so now it's just one of the boys (influenza, sars, those and more here) Let's hope, someday, it can join this list.

[-] floofloof@lemmy.ca 2 points 1 year ago* (last edited 1 year ago)

I wore a mask in crowded places for three and a half years without getting sick. Then I stopped and two weeks later I got COVID. It wasn't much fun and it took weeks to get over. Maybe that was coincidence, but now we're back into flu season I'm wearing masks in crowded places again. I figure each person who wears one makes it a little easier for those who would like to but don't want to go against the social tide.

[-] jjjalljs@ttrpg.network 3 points 1 year ago

If not wearing a mask meant only that person died, I'd be extremely happy to let the idiotic right wing die. Unfortunately, they affect everyone else.

We really need to stop treating right wing extremism as the same "difference of opinion" tier as "i like my bedroom walls painted blue vs green".
