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…
The people that need to know this- won’t listen, and the people that don’t need to know- don’t need to know because they already know it.
It’s not about the morons that refuse to wear mask. It about people that believes in truth checking that the things they know are correct. If we wore masks and never tested if that did anything we would be as stupid as any anti-vaxxer.
Even if the research had come out that masks did absolutely nothing to protect against Covid, I would have absolutely no regrets for masking up. We did what we thought was the right thing based on the evidence available and it harmed no one. The worst that would’ve happened if we were wrong (outside of a false sense of security) is that we looked silly for awhile. The people that were vehemently against wearing masks were tool-sheds who were manipulated into their position by an Administration who assumed it would affect Democratic-leaning cities/states more and who are so blinded by their anti-science views that they didn’t even understand the threat posed by Covid. Mask wearers did the right thing and the evidence backs us up. Anti-mask idiots hopefully learned an evolutionary lesson, but I doubt it has really ever sunk in.
I remember reading a while back that MAGA counties had significantly higher death and serious disease rates. Probably still do. I’m not sure about the apartment Republican strategy of actually working to kill their core voters, but I guess we’ll see how it works out for them.
I’ve read that TrumpCo wasn’t as concerned with it out of the belief that more populous Democratic counties/states would be more heavily impacted by Covid. If anything, they tried to take advantage of Covid to use it as a natural bio-weapon and this is probably their worst, yet least talked about crime that they’ll likely never face charges over. The strategy apparently blew up in their faces though, but by the time anyone realized, it was already too late to do anything about it. The damage had already been done.
The real problem for the Right Wing is that masks are at their most effective stopping the wearer’s germs from getting OUT, even though they’re also pretty effective at stopping others ’ germs from getting IN. They can’t stand the idea of sacrificing even a tiny bit of comfort for anyone else to benefit. Even if it also helps themselves.
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.
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
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.
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!
They’re normalized in some places. I see people wearing them and not just the “Covid isn’t over!” folks.
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.
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.
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.
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”.
The problem is the cdc basically lied at the start and killed all their credibility before things even got started. Then you had apologists claiming they didn’t lie, making everything even worse.
They did not provide the context, which was misconstrued as lying.
Everyone did not need to wear a mask at first because it was not widespread enough for them to be effective for the general population compared to making sure medical staff who were far more likely to be exposed had masks. Masking by the general public at the very beginning was a waste of masks compared to just reducing the time spent in groups. It became effective as time went on and the mask supply ramped up.
That context doesn’t make it not a lie. They could have said mask supplies were needed for medical professionals first, but they chose a convenient lie.
The political body responsible for messaging and action during a pandemic immediately ruining it’s credibility is a pretty big problem. It creates the opening for a masks don’t work campaign, when the cdc opens with masks aren’t useful.
They initially stated masks weren’t effective for general population use. This was a lie. There were reasons at the time for the lie, but it doesn’t make it not a lie.
They literally didn’t lie, the post is linked in this thread. Of course at the time people weren’t linking the source, they were quoting part of one sentence and getting inflamed that half of a sentence seemed to say the opposite of what the actual post said.
It literally says “not recommended -for the general public- at this time” how is that miscontrued to “they don’t work”? It doesn’t say that at all. In fact the video in that post, I know it’s a full 30 seconds long and slow and boring… but the video specifically says to save them for medical professionals and others in close contact with the infected. Again very much stating specifically that they do help.
The fact that the idea of an air filter is controversial is frankly amazing.
They apparently only work in every situation except when put over your face.
Many think that it takes only 1 virus to catch the disease when, in reality, your body will easily deal with a small amount of unknown pathogens and does so many times a day.
Masks work because they reduce the overall viral load, so your immune system isn’t overwhelmed.
What also doesn’t help is how unintuitively percentages scale. A mask that is 90% effective doubles the viral load if compared to a mask with 95% effectiveness, even tho the difference is “only” 5%.
Influenza data shows that it takes about 1000 viral particles to infect a human. Assuming COVID 19 is similar, reducing viral load also significantly reduces severity of disease if you get it.
Do you know if the infection threshold is similar across different influenza strains or are some more infectious than others?
