Do Masks Work?

[kaz]

You read one paragraph and just stopped reading?

You're THAT reading challenged?

It was too much of an effort to read any further?

Ya know what "first" means? Yea...there are more to follow...

Fuckin Trumpers.

Jesus

Actually I criticized several of the examples, so I obviously didn't just read the first one you stupid fuck.

No one starts with a minor, irrelevant example to make their argument when there are actual good arguments. That the first, go to example was TWO PEOPLE and it was only "investigated" later shows they are trying to make a contrived point.

You picked the lame ass article, douche

Human Studies of Masking and SARS-CoV-2 Transmission​

Data regarding the “real-world” effectiveness of community masking are limited to observational and epidemiological studies.

• An investigation of a high-exposure event, in which 2 symptomatically ill hair stylists interacted for an average of 15 minutes with each of 139 clients during an 8-day period, found that none of the 67 clients who subsequently consented to an interview and testing developed infection. The stylists and all clients universally wore masks in the salon as required by local ordinance and company policy at the time.36
• In a study of 124 Beijing households with > 1 laboratory-confirmed case of SARS-CoV-2 infection, mask use by the index patient and family contacts before the index patient developed symptoms reduced secondary transmission within the households by 79%.37
• A retrospective case-control study from Thailand documented that, among more than 1,000 persons interviewed as part of contact tracing investigations, those who reported having always worn a mask during high-risk exposures experienced a greater than 70% reduced risk of acquiring infection compared with persons who did not wear masks under these circumstances.38
• A study of an outbreak aboard the USS Theodore Roosevelt, an environment notable for congregate living quarters and close working environments, found that use of face coverings on-board was associated with a 70% reduced risk.39
• Investigations involving infected passengers aboard flights longer than 10 hours strongly suggest that masking prevented in-flight transmissions, as demonstrated by the absence of infection developing in other passengers and crew in the 14 days following exposure.40,41

At least ten studies have confirmed the benefit of universal masking in community level analyses: in a unified hospital system,42 a German city,43 two U.S. states,44, 45 a panel of 15 U.S. states and Washington, D.C.,46, 47 as well as both Canada48 and the U.S. 49-51 nationally. Each analysis demonstrated that, following directives from organizational and political leadership for universal masking, new infections fell significantly. Two of these studies46, 47 and an additional analysis of data from 200 countries that included the U.S.51 also demonstrated reductions in mortality. Another 10-site study showed reductions in hospitalization growth rates following mask mandate implementation 49. A separate series of cross-sectional surveys in the U.S. suggested that a 10% increase in self-reported mask wearing tripled the likelihood of stopping community transmission.53 An economic analysis using U.S. data found that, given these effects, increasing universal masking by 15% could prevent the need for lockdowns and reduce associated losses of up to $1 trillion or about 5% of gross domestic product.47

Ohhhhhhhh

You want me to join your racist club.
Sorry, can't pay the moral dues.

you're afraid of china?

Two fucking people, you are a cultist, a racist and a total moron

symptomatically ill isn't ill. I know, I know symptomatically means ill, hahahahahahahahaha if no one had wuhan, neither did the two hair stylists. The study is fking evidence that symptomatic people are not infectious, the two hairstylists were not infected.

 

[jc456]

Masks work

can't prove it friend. You should tell the manufacturers to stop saying they don't.

again, the two subjects weren't contagious, neither of them got the wuhan bug. doh!!!!!

again, the entire post is useless. it isn't a study. there is no possible conclusion one could produce from such stupidity.

That's the problem with dumb ass Lesh using TWO people. There's nothing normal about this. It takes many more to do any sort of real study. And they weren't even in control, they evaluated it when it was over.

What Lush didn't have was a real study with a statistically significant sample that actually tested masks and when they work or don't work. It was a lot of, here's one data point. Here's another. You put them together and you learn nothing ...

 

[kaz]

Note in defending it, here is what Lesh didn't say. Look at these studies ...

He just screamed it was unfair to think they started with a powerful study supporting mask wearing when the FIRST ONE was a review of TWO PEOPLE that happened AFTER IT WAS OVER.

Then there was the moronic review of national Covid data and a bunch of other lame studies.

What he did was give a great example of how poor the data is that supports masks and how little the fascist Democrats care because it isn't about Covid, it's about power

Chain link fence would eventually get some mosquitoes stuck to it if you had some on the roof of your car and drove across the country, so yea, I can see where n95 masks could technically help by trapping 1 out of every two billion viruses that flow around and through them.

A N95 is much more effective than that.

While I will agree it does not prevent exposure from all particles, but it is certainly NOT a chain link fence.

It sounds like you need to do a little research on this topic.

 

[rightwinger]

Hell no they don't work. That fucking imp Fauci even said so...before he said they do...then two do better.

The entire world endorses masks

Only Conservatives fight against masks

Let’s not even talk about vaccines

Do you wear sealed goggles as well?

Aerosol droplets also fly into your eyes causing infection.

So do you wear those?

I am sure your mask is an N95 as well which still only block~46% of aerosol particles.

Not the normal cloth masks which only block 10-12%.

I am SURE you always wear the N95.

Nevertheless, high-efficiency masks, such as the KN95, still offer substantially higher apparent filtration efficiencies (60% and 46% for R95 and KN95 masks, respectively) than the more commonly used cloth (10%) and surgical masks (12%), and therefore are still the recommended choice in mitigating airborne disease transmission indoors.

You fuckin lib fags.

Obvious is obvious

 

[rightwinger]

Yes Masks work
Vaccines work better

Conservatives won’t do either
That is why we still have Covid

Decades of hazmat and respirator training. Full on tent style respirator fit tests every 2 to 3 years. I am VERY qualified to discuss respirators. If we discuss the "potential" filtration capabilities of N95, in the correct lab conditions, the N95 will surface as the winner, and will have remarkable results. Unfortunately, N95 masks do not perform anywhere near their filtration potential in the real world. In the real world, n95 does not seal against the face on inhalation, and exhalation either pushes the mask away from the face or exhalation escapes through a valve on valve equipped models. The remarkable "potential"of n95 masks is wasted on a mask that allows air to pass easily around it. When I am working with hazmat that requires breathing protection, I use a 3m cartridge style respirator on top of a clean shave. For more dangerous hazmat, I wear full face and supplied air.

it's called an analogy. look up the definition. hahahaahahahahahaha. the manufacturer prints the words on the outside of the box, doesn't protect against wuhan 19.

Here is how masks perform in the real world. No scientific studies can replace how things work in the real world.

And those aerosols drop to the floor after just a few minutes...INSTEAD of shooting out 6 to 12 feet in front of them

Oh and it's amazing how well that chain link fence prevents even smoke from going through it
