Do Masks Work?

[EvMetro]

At least 5 times on this very thread it has been shown that your "chain link fence" DOES protect against virus transmission

Chain link fences do not stop mosquitoes any more than a mask stops viruses. The holes in mask are even larger compared to viruses and droplets than those holes in chain link fences are compared to mosquitoes.

youre contracting the study that showed they do work.
not as well as a tight-fitting mask, but better than nothing.

they aren't better than nothing. you think david copperfield made the statue of liberty disappear don't you?

 

[jc456]

Thus proving that the masks are not holding back water vapor, and since the water vapor is what traps virus, the mask do not hold back any virus.
The fact masks start out dry and will temporarily slow the spread of virus for the first 15 minutes, does not at all mean they work after a half hour.
Once the saliva on the mask has had a chance to dry out, masks no longer work at all.

shhhhh lesh doesn't know much about life.

 

[dudmuck]

Wrong.
It is trivial to fog up a mirror, glasses, etc. after your mask becomes saturated with moisture after about 15 minutes.
So masks only work for about 15 minutes, until they become saturated and the saliva starts evaporating again.

experiments showed masks became slightly more effective when moist.
also humidity caused by mask aids protection of the wearer.

Masks do not work.

nope, you'd post one of their studies if this were true.

Show me their crash dummies. Oh, that would be the entire demofk network. holy fk? are you saying demofks don't get sick?

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

Filtration for Wearer Protection​

Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns. The relative filtration effectiveness of various masks has varied widely across studies, in large part due to variation in experimental design and particle sizes analyzed. Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron .14,17-29 Some materials (e.g., polypropylene) may enhance filtering effectiveness by generating triboelectric charge (a form of static electricity) that enhances capture of charged particles18,30 while others (e.g., silk) may help repel moist droplets31 and reduce fabric wetting and thus maintain breathability and comfort. In addition to the number of layers and choice of materials, other techniques can improve wearer protection by improving fit and thereby filtration capacity. Examples include but are not limited to mask fitters, knotting-and-tucking the ear loops of medical procedures masks, using a cloth mask placed over a medical procedure mask, and nylon hosiery sleeves.31-35

Yes, as I said, moisture is what makes masks effective at all.
But the point is that after 15 minutes, the masks become saturated, take on no more moisture, and instead start evaporating moisture.
Once they do that, they release all the virus they trapped temporarily for 15 minutes.
So the correct way to think of masks is not a virus trap or blocker, but only a 15 minute virus delay mechanism.

If masks did not evaporate water vapor, then they would be dripping after 15 minutes.
But they do not drip.
That is because they evaporate moisture as fast as it is exhaled.

That is obviously a lie.
The CDC has made hundreds of ridiculous claims.
Is there any reduction of spread with masks?
Sure, but that only ensure the greatest death toll possible, because we don't want to slow infection.
We need to either eliminate it completely with full quarantine or by herd immunity.
Masks only help if you are doing full quarantine.
Masks interfere with herd immunity, thus making the epidemic last longer, and killing more people.

Except obviously I am right, have the facts, and can prove it with logic.
If you were rights, then we would not have had kept the epidemic going for almost 2 years, and had 660,000 dead.
Clearly the strategy we are using is wrong, stupid, failed, and to not be repeated.
Flattening the curve clearly does not work, can not end any epidemic, and should not have been done.

didnt you see the bottom line?

Moisture and condensation had very little impact on effectiveness for any of the masks. If anything, the cloth masks actually captured about 6% more virus-sized particles after 3 hours.

maximum 5 percent difference over 3 hours

further reading, a study where they included evaporation in their modeling.

Didn't you read any of it?
It was a COMPUTER MODELING SIMULATION.
Which can easily give any result you want.
I am talking about the actually, real, result of laboratory testing.
And the reality is that mask make it worse for viruses, after a half hour.
They are only good for 15 minutes or so, or with larger objects like bacteria.
