Title: Masks
Post by: Ergel on March 31, 2020, 08:27:23 AM
Someone is selling KN-95 masks from China near me. 60 shekel for 2 or 100 shekel for 4. It says Naisian on them. Are they worth buying? If I have a beard, will they do anything for me? I think they said they are washable? Is there such a thing? Or are they single-use only?

A mask is good only to protect others from yourself in case you're positive or with symptoms or just for precautions. To protect yourself from others you'll need more than that, especially if you have a beard.

Please don't post wrong information. An N95 mask will protect you. A surgical mask is to protect others.

Correct. But he said it authoritatively, so it must be true.
But on the other hand, it wasn't on WhatsApp so it might not be true.

Didn't see anyone mention N95 until your post. KN95 is not N95.
KN95 is Chinese standard and not equivalent.

I will speculate that it is slightly more since what goes through the mask itself is filtered better but not by a tremendous amount.

A surgical mask is basically open from the entire top and sides and welcomes all airborne particles. N95 masks, even if poorly fitted, will be a much tighter fit around the face, and even if not sealed 100%, will significantly reduce airborne particles compared to surgical. IMHO.

Yes but how much I have no idea.
I had to wear respirator masks for many months. Even a perfectly fitted one is not 100%.
With a beard a fitted mask (N95) will still fit better than a surgical mask. It still filters better so based on that I would say yes but that is only a guess.

Nice. So force applied being much higher for KN95 means what? That the mask is theoretically tighter but also much less comfortable?

With a beard a fitted mask (N95) will still fit better than a surgical mask. It still filters better so based on that I would say yes but that is only a guess.
So the reasoning is that a 3 ply mask is more porous so the air you breathe will come through the mask. An N95 is less porous so if there is any gap unfiltered air will come through that path of least resistance. So that's why a surgical mask may be better for a beard or if you were not fit tested. Many people still opt for the N95 and try to make sure it's tight but still, everything depends on the mask, beard person
If you do wear a mask make sure to wear it properly. Follow this link for instructions on how to properly wear and remove a face mask

There have been many KN95s that have lost FDA approvals over the last few days.

In fact it's not even being allowed into the country now.

The concern is that the droplets aerosolize and can get past a surgical mask. They arent sure how much of a concern this is.

Since I can't get the masks that I have to fit I use it even though it leaks. The issue is that my glasses fog up.

A trick I learned a few years ago is to take regular dish soap and smear a very thin layer onto the glasses (both sides). Let it dry then buff it out with a cloth/tissue until it's perfectly clear. This will prevent any fogging up until the soap gets washed off.

Works extremely well. Try putting your glasses in the freezer with soap on only one lens for a few minutes and take it out to see the full effect.

Thought I'd share in case anyone finds it helpful.

Well, Dan asked for a summary of the article that @aygart posted, but it's disappeared.  And while I wrote a summary, this (better) summary with pictures has been published, but I'll paste mine anyway. Is this too long?

https://www.forbes.com/sites/alicegwalton/2020/06/13/face-masks-may-be-the-key-determinant-of-the-covid-19-curve-study-suggests/#44ac7f116497

Identifying airborne transmission as the dominant route for the spread of COVID-19, by Renyi Zhang and others, PNAS, published June 11, 2020

Short summary: Why did COVID-19 stop spreading so much faster in China than in Italy and the US?  And why did new cases plateau so much earlier in NYC than in the rest of the United States?  In both cases, the authors conclude that the onset of mandated face coverings made the difference, preventing tens of thousands of infections. 

Longer summary:
In China, the early response to the outbreak was SD, masks, extensive testing, and contact tracing, all put into effect simultaneously.  In China, the number of new cases increased for about 3 weeks after the lockdown, and had reached a plateau about a week after that. 

In NYC and Italy, the early response was hand washing, SD, stay-at-home, but masks were not required until a month had passed.  In these places, the number of new cases increased rapidly for about 4 weeks after the early SD requirement, and began to decrease only later, after the face covering requirement was implemented.

In the rest of the US the early response was hand washing, SD, stay-at-home and masks were not required, and the number of new cases were continuing to rise steeply (at the time they looked, May 9). 

The timing of these events suggests that mask-wearing was critical in decreasing the spread of coronavirus, quickly in China and after a delay in NYC.

A second piece of evidence they bring is from plotting the total cases in NYC, using a statistical technique called linear regression.  Their graph shows that if the original policy (SD, stay at home) had continued, the number of cases would have been much higher than it actually was.  The pivot point occurred on April 17, when masks were first required, and the caseload started to decline. 

Similarly, their comparison of new infections in NYC compared to the US as a whole (minus the NYC cases) shows that corona cases declined steeply after the April 17 mandated face covering, while new cases remained high during that time throughout the United States. 

Why would masks have such a dramatic effect?

Back in March, experts thought that the virus is communicated by droplets that we expel when we cough or sneeze.  These droplets are pulled down by gravity, so are usually found within 3 feet of a sick person, so we were advised to stay away from an obviously sick person and to wash our hands and keep them away from our face to avoid transferring a virus-containing droplet to our mouth, nose or eyes.  Masks were recommended only for the sick person themselves, to prevent their expelled droplets from contaminating others (WHO, April 6).

But later in April, scientists learned that theres another way that virus can be expelled, in the form of much smaller particles, called aerosols, especially by people talking loudly or singing. 

You can visualize the difference by spraying a window cleaner and an air freshener on a mirror.  The window cleaner forms small droplets that soon start rolling down, attracted by gravity.  The air freshener forms an aerosol of tiny drops that remain where they fell on the mirror.  In fact, we spray air freshener into the air knowing that these miniscule particles and their pleasant odor will remain suspended in the air for quite some time.

The realization that viral particles were found in aerosols convinced the experts that the virus could be inhaled by someone who was more than 3 feet from an infected patient, or even in a room where an infected person had previously exhaled, and this led to expansion of the advice to wear masks: 

   The knowingly infected should wear masks to avoid spreading their droplets and aerosols, which can contain virus. 
   The unknowingly infected (that is, presymptomatic, when viral expulsion seems highest) should similarly wear masks to avoid spreading the virus. 
   The healthy uninfected should wear masks to avoid inhaling the aerosols of the two previous groups. 

They conclude that wearing of face masks in public corresponds to the most effective means to prevent interhuman transmission, and this inexpensive practice, in conjunction with extensive testing, quarantine, and contact tracking, poses the most probably fighting opportunity to stop the COVID-19 pandemic, prior to the development of a vaccine.

My comment:
Finding that the number of cases in NYC began to decrease around the same time as mask wearing was required is not sufficient to conclude that mask wearing was responsible for the decrease.  Did people actually obey the mask-wearing regulation?  Were there other events that occurred around that time that contributed to the decline in new infections?  This paper provides evidence that mask-wearing is important, but it's weak evidence, and the argument could be strengthened by other research.

Finding that the number of cases in NYC began to decrease around the same time as mask wearing was required is not sufficient to conclude that mask wearing was responsible for the decrease.  Did people actually obey the mask-wearing regulation?  Were there other events that occurred around that time that contributed to the decline in new infections?  This paper provides evidence that mask-wearing is important, but it's weak evidence, and the argument could be strengthened by other research.

Excellent comment. If I may, I'd like to offer an abbreviated version: Correlation does not prove causation!

(Side note: I almost puked several times hearing Cuomo's arrogant causation claims today, coupled with his muscle flexing.)

Right!  But correlation does not disprove causation either.  It's just a hint, needs to be followed up.

What this does suggest, if proven, as many have suggested for other reasons as well:

the viable route forward is more masks less lockdowns. overall less pain to the economy and even the individual living their lives.

or as another article put it, if we evaluate the various measures as ROI closing businesses may be high cost/low return, closing schools may be high return but high cost and universal masking/sanitizing along with closing major events (1000s of people) are our most low cost/high return.

the emerging evidence on airborne vs touching etc. only confirms this

Good point (and nice summary BTW)

In NY mask compliance in subways and on the street was never great (i'm not in NY but commenting based on the news reports at the time). In NJ they never required masks other than in stores. Is there evidence that they took longer to bend the curve?
The states that still had cases rising were most likely to lax lockdowns in general not because of masks specifically.
China may have stopped the spread quicker because they did a much stricter lockdown then we did.

Well, Dan asked for a summary of the article that @aygart posted, but it's disappeared.  And while I wrote a summary, this (better) summary with pictures has been published, but I'll paste mine anyway. Is this too long?

https://www.forbes.com/sites/alicegwalton/2020/06/13/face-masks-may-be-the-key-determinant-of-the-covid-19-curve-study-suggests/#44ac7f116497

Identifying airborne transmission as the dominant route for the spread of COVID-19, by Renyi Zhang and others, PNAS, published June 11, 2020

Short summary: Why did COVID-19 stop spreading so much faster in China than in Italy and the US?  And why did new cases plateau so much earlier in NYC than in the rest of the United States?  In both cases, the authors conclude that the onset of mandated face coverings made the difference, preventing tens of thousands of infections. 

Longer summary:
In China, the early response to the outbreak was SD, masks, extensive testing, and contact tracing, all put into effect simultaneously.  In China, the number of new cases increased for about 3 weeks after the lockdown, and had reached a plateau about a week after that. 

In NYC and Italy, the early response was hand washing, SD, stay-at-home, but masks were not required until a month had passed.  In these places, the number of new cases increased rapidly for about 4 weeks after the early SD requirement, and began to decrease only later, after the face covering requirement was implemented.

In the rest of the US the early response was hand washing, SD, stay-at-home and masks were not required, and the number of new cases were continuing to rise steeply (at the time they looked, May 9). 

The timing of these events suggests that mask-wearing was critical in decreasing the spread of coronavirus, quickly in China and after a delay in NYC.

A second piece of evidence they bring is from plotting the total cases in NYC, using a statistical technique called linear regression.  Their graph shows that if the original policy (SD, stay at home) had continued, the number of cases would have been much higher than it actually was.  The pivot point occurred on April 17, when masks were first required, and the caseload started to decline. 

Similarly, their comparison of new infections in NYC compared to the US as a whole (minus the NYC cases) shows that corona cases declined steeply after the April 17 mandated face covering, while new cases remained high during that time throughout the United States. 

Why would masks have such a dramatic effect?

Back in March, experts thought that the virus is communicated by droplets that we expel when we cough or sneeze.  These droplets are pulled down by gravity, so are usually found within 3 feet of a sick person, so we were advised to stay away from an obviously sick person and to wash our hands and keep them away from our face to avoid transferring a virus-containing droplet to our mouth, nose or eyes.  Masks were recommended only for the sick person themselves, to prevent their expelled droplets from contaminating others (WHO, April 6).

But later in April, scientists learned that theres another way that virus can be expelled, in the form of much smaller particles, called aerosols, especially by people talking loudly or singing. 

You can visualize the difference by spraying a window cleaner and an air freshener on a mirror.  The window cleaner forms small droplets that soon start rolling down, attracted by gravity.  The air freshener forms an aerosol of tiny drops that remain where they fell on the mirror.  In fact, we spray air freshener into the air knowing that these miniscule particles and their pleasant odor will remain suspended in the air for quite some time.

The realization that viral particles were found in aerosols convinced the experts that the virus could be inhaled by someone who was more than 3 feet from an infected patient, or even in a room where an infected person had previously exhaled, and this led to expansion of the advice to wear masks: 

   The knowingly infected should wear masks to avoid spreading their droplets and aerosols, which can contain virus. 
   The unknowingly infected (that is, presymptomatic, when viral expulsion seems highest) should similarly wear masks to avoid spreading the virus. 
   The healthy uninfected should wear masks to avoid inhaling the aerosols of the two previous groups. 

They conclude that wearing of face masks in public corresponds to the most effective means to prevent interhuman transmission, and this inexpensive practice, in conjunction with extensive testing, quarantine, and contact tracking, poses the most probably fighting opportunity to stop the COVID-19 pandemic, prior to the development of a vaccine.

Looking at graph A in this image from the article, I would conclude that the number of cases increased for 3 weeks after the stay at home order before starting to descend and continuing to descend for many weeks after with the face mask requirement having no effect. Including the 3 weeks of increase as part of the downward trend is a scam.(https://specials-images.forbesimg.com/imageserve/5ee52ec5ec3cd10007fe3734/960x0.jpg?fit=scale)

@avromie7 If you're saying what I think you're saying, then I agree with you 100%. 

These scientists asked "Do case numbers change after masks were required?" so they drew two dotted lines, one that best fit their data before masks - when cases were only slightly declining - and one line after masks - which show a more dramatic decrease in cases.  (first graph A)

But you come and say "Hey, wait a minute, guys!  There's another way to analyze this!  Instead of starting with the assumption that masks make a difference, just take a look at your data!" and you would draw two lines that show that cases increased for a few weeks until April 12, and then started to decline before masks were required! 

I would add: If masks made the critical difference, then new infections should have decreased immediately, but new cases wouldn't have been reported until several days later when symptoms appear.  So we would have expected the decline in reported new cases to begin a week after face covering began, not immediately.

So all of this is why it should be considered only "weak evidence", which is consistent with the importance of masking.  We'd have a much more convincing argument if it had been decreed that masks had to be worn in Italy but were forbidden in the US, and then we would have had a clearer case for concluding whether or not masks were important.  But obviously we can't do that kind of experiment, and are stuck with the data we have.  As more data analysis is added, we'll get better conclusions, rather than relying on just this paper.

The only part of your comment that I disagree with is calling this "a scam", which implies intentional fraud. The Forbes journalist wasn't as astute as you, and didn't notice the problem with their analysis, but experts in epidemiology surely would have.  (Note that the scientists who did this were actually chemists.)  This is the kind of dispute that always happens as scientists try to reach agreement, and the conflict is usually resolved when additional data either supports or refutes it.

I would think that cases would take a while (more than a week, likely 2 or 3) to start going down after the correct procedures were put in place. We have to remember that people only would get tested after a couple of days with symptoms and the results come back a few days later. Also family members would likely get it if they stayed at home with a sick person as no one was socially distancing or wearing masks around family members unless they had symptoms which was usually to late to stop transmission between family members. This suports the theory that stay at home orders is what really slowed it down.

I don't know who deserves the blame and who should be given the benefit of the doubt that they're just "passing on" the information they received, but someone published something that is fatally flawed to the point that a layman like me glancing thru the article says something doesn't make sense. I can compare the week before the mask requirement to the weeks after and you'll see the downward trend slowed when masks were required.

Alternatively, it has nothing to do with the stay at home order, rather when people decided to stay home (which actually happened a few days before the stay at home order) and there was no need for government involvement.

Stay-at-home occurred in NYC and rest of the country, and the flattening of the curve is seen in both (A and B in the graph avromie7 posted) but mask-wearing had only been implemented in NY, and the steep decline is shown only in NYC (A, not B).  It is difficult to disentangle how much each contributed, just from looking at these graphs.

It's not fatally flawed.  The authors interpreted it one way, and you (admirably) found another way to interpret it.  You should always be reading this way, asking "what did you base your conclusions on?" and "is there another interpretation for your data?"

It's true that another problem with this study is that they don't know how people behaved -did they actually stay home when the government required it, did they wear masks, etc.
 
There was no need for the government to tell me to stay home, and no need to tell you to stay home.   But you know that fool who lives on the next block over...?  I'm glad the government told him to stay home.

Sadly many of the fools down the block did not listen and many who stayed home on their own are still not going out.
Based entirely on what I am seeing in my community, it seems people made their own decisions and stuck with them nothing to do with govt regulations.

You mean to tell me that only people in NY were wearing masks. I dont think that is true. Perhaps, the reason why it kept on going up outside of NY was because people were less cautious as it wasn't going around much there.

You obviously live in a community very different than mine. In my community almost no schools closed until they were forced to by the government, barely anyone wore masks in stores until they were mandated, few even heard of the concept of social distancing until it was required, etc.

Yes, at least according to the article, "All New Yorkers were mandated to use face covering in public starting on April 17, when social distancing was not possible."

Aerosolized spread was known from February, not April.
Again, from the article: "Recent experimental studies have examined the stability of SARS-CoV-2, showing that the virus remains infectious in aerosols for hours (12)"  Reference (12) (https://www.nejm.org/doi/full/10.1056/nejmc2004973) was published in the April 16 issue of NEJM, though online March 17.

I gotta hand it to you, @yuneeq! How do you keep up with this?  I can barely keep track of the papers I read last week, let alone remember what happened in February.

I suspect that you and I agree that (a) masks may be helpful, (b) this paper doesn't add much, and (c) it isn't worth discussing further. 

I'll just take a moment to point out why the researchers said that aerosol transmission was shown in April, while you "knew" it in February.  It's because scientists prefer to cite a published paper, rather than the sources you listed. 

Feb 19. Global Times.
Chinas health agency says that aerosol transmission occurs, based on a statement by a health official at a press conference.  No data or explanation was given, nothing in writing.

Feb 21.  The Scientist
The article says that aerosolized transmission was discussed by a Shanghai official in early February, so this might be referring to the above report, but then quotes an Australian virologist who says that there's no evidence that aerosols spread covid.

Feb 20. Bloomberg
This quotes a WHO report saying aerosol transmission can be envisaged as occurring during certain medical procedures, and should be studied further.  No data to show it occurs.

March 17. NEJM online
April 16. NEJM
This is the reference [12] cited in the article I reviewed, that showed coronavirus in aerosol, and seems to be the first published research.

after March/April Bloomberg, update to Feb 20 article
This page currently says Researchers who aerosolized it intentionally found active virus can float in the air for as long as 3 hours., and links to the NEJM April article, so this sentence could not have been in the Feb 20 version.

Of course, many people had read the earlier news articles, and it was being discussed and even acted upon in February.  But scientists have long used the date of publication as "discovery" date, so attributing the discovery of aerosolized transmission to March/April seems appropriate.

If they were confident that COVID only spread via droplets until then, then they are literally complete idiots. The info coming from China and elsewhere strongly suggested that aerosolized transmission was probable if not factual. Remember this info was coming from China, which famously denied that COVID spreads human to human a month earlier. Theres reason to believe anything negative about COVID that is coming from the Chinese, at the very least to entertain the option. Not to even entertain the option until you have a peer reviewed study published is either complete arrogance or lack of intelligence.

    Initially, experts thought that the virus would be like measles, communicated by droplets that we expel when we cough or sneeze.  But mid-February, info from China suggested that aerosolized transmission could also occur.  Shocked and horrified, scientists raced to investigate this, and soon confirmed that active virus could be found in aerosols, both in artificial aerosols created in the lab, and in air samples from hospital rooms where covid patients had stayed.  This eventually led to a greater emphasis on the importance of mask-wearing. (For details of their study, see their NEJM article, publication date April, though published online on March 17, and certainly discussed among health professionals even earlier.)

Not looking to argue, but regarding one point of yours - measles is actually airborne. Re: COVID - I originally understood that it is aerosolized but not necessarily airborne, but now I'm seeing some research that equates aerosolized spread with airborne spread. I understood the difference that an aerosol is a small droplet that can linger around for a few seconds, light enough to float with an air draft and spread to another side of the room. And airborne would be a microscopic droplet that can basically last for a couple hours in mid air.

If you're bored, read this article and come out more confused than when you started: https://first10em.com/aerosols-droplets-and-airborne-spread/

I have no clue. I can see no justification for heckling people who wear masks.

ETA: My gut feeling is that the most common emotion towards those wearing a mask is pitty on them that they haven't had COVID-19 and recovered. Definitely no reason to heckle. Though at this point I feel terrible for not testing positive for COVID-19, as that would have allowed me to visit EY without quarantine. My positive IgG antibody test doesn't help.

Face shields are most useful in addition to wearing a mask, not instead of. There isn't great protection from aerosolized droplets with just a face shield, face shields are used to give fluid protection.

So are you saying that if an infected person wearing a face shield sings, sneezes or coughs, the aerosol droplets fly towards the shield, take a turn downward when they realize the shield is there, escape, and then float back upward once they clear the shield? That's truly amazing!

Try it. Put some food coloring and water into a spray bottle, lay out a white sheet in a room with the same expected air movement, spray it at a shield, and see where the droplets end up.

I found this article from May 29: https://www.webmd.com/lung/news/20200529/face-shields-may-be-next-step-to-prevent-covid

It quotes a study in JAMA recommending the use of face shields in certain situations, however states there is no evidence about containing the virus: https://jamanetwork.com/journals/jama/fullarticle/2765525

"Of note, no studies have evaluated the effects or potential benefits of face shields on source control, ie, containing a sneeze or cough, when worn by asymptomatic or symptomatic infected persons. However, with efficacy ranges of 68% to 96% for a single face shield, it is likely that adding source control would only improve efficacy, and studies should be completed quickly to evaluate this."

So in your experiment are you suggesting spraying at the inside of the shield from a distance of 1", 2" or 3".

Anecdotally, at the LTC facility where my mother stays, they provide the residents with face shield for encounters with visitors. Visitors are required to wear face masks (I don't know what would happen if a visitor tried to come with a face shield) and maintain a distance (all outdoors, for no more than 10 minutes, 1 visitor at a time). 0 infection rate in that facility.

That maybe has to do with the requirement to replace the water in the bottom בור occasionally. The fact that the top בור has warm water and the bottom בור has cold water, lends itself to the laws of physics that the water isn't likely to mix that much. I don't think that means the water won't mix at all, just at a much lower rate than it would with a בור בצד בור.

Even healthy people will have issues with carbon dioxide.

A team of Stanford engineers is developing an N95 face mask to counteract the side effects of oxygen deficiency. In an interview, John Xu, a mechanical engineer behind the effort, said: N95 masks are estimated to reduce oxygen intake by anywhere from 5 to 20 percent. Thats significant, even for a healthy person. It can cause dizziness and lightheadedness. If you wear a mask long enough, it can damage the lungs. For a patient in respiratory distress, it can even be life threatening.

I'm confirmed antibody positive. I can't be passing covid germs to anybody.  why should I wear a mask?
(I assume we should, if we chooses to continue, move this to one of the numerous covid threads.)
Maybe the thread called Masks (https://forums.dansdeals.com/index.php?topic=115316.0)?  But as long as I'm here, the reasons to wear a mask are
  • to avoid exhaling covid germs that may infect others
  • to avoid inhaling covid germs that may get you sick
  • to avoid touching your nose and mouth with hands that may contain covid germs
  • to contribute to the creation of a social environment in which mask-wearing is accepted and expected
You think you're immune to covid, so 1-3 don't apply, but 4 does. 
I'm sure you agree that those who are currently infected, or who haven't been infected yet should be wearing a mask to protect themselves and others.  But people don't want to stick out from the crowd, and those who should wear a mask may reject it for this reason.  Your wearing a mask helps encourage mask-wearing by those who really need to.
4 alone is a weak reason that although true and virtuous wont convince the public.
It was intended to convince @ckmk47 and other virtuous folks.

Let's be honest... everyone in israel wears masks and its spreading there. Masks are cute and nice but they don't actually have enough of a meaningful impact to make anyone who had covid to take care about it. And look at whats going on around us, people are literally destroying cities, defunding police departments and creating total anarchy in the streets. You think these same guys care about what any dr or official says... they don't. Thats why masks will most likely  never be widespread in the us.
ckmk47 asked why she personally should wear a mask, and my answer was based on the assumption that she is not out there destroying cities, either literally or figuratively, or creating anarchy, either total or partial.

They must not read DDF ;D

Except the fact that the incubation period is very long and spread disease even without being sick. No one knows they have the virus until they develop symptoms and get tested, and by then it's way too late. Not to mention that the sick people don't have any masks because the CDC told them not to buy any.

a) Masks prevent you from touching your face.
b) The virus is spreading asymptomatically, and the viral payload is highest at the beginning of infection. Most of the community spread infection is coming during this period. Sick people stay at home more and cause less infection than healthy asymptomatic patients. Telling only sick people to wear masks does almost nothing to stop the contagion.
c) Telling people not to buy masks until they're sick means they won't have a mask once they get sick.
d) China implemented mask wearing on the entire population, and they're containing the outbreak. Is this solid proof that it's helping? No, but it sure isn't hurting them and it seems like it helped.
e) The claim that a surgical mask or an improperly fitted mask means that a person is not fully protected, is true. But, though it might not block all virus particles all of the time, it will still block all virus particles some of the time.
f) Most of the reasons given by the CDC are basically - "hey there's unrelated reasons where it doesn't work!!". Correct, not sanitizing properly can still lead to infection even with a mask. But even the most properly fitted mask, where the user doesn't wear goggles, is risking infection. Stick with the facts - wearing a mask decreases likelihood of infection.
g) What mask shortage? Medical staff don't need masks if anyways they're completely useless for prevention (according to CDC). Just save a couple thousand masks for the 160 COVID patients and all the medical staff will be fine and dandy.
h) Is it really that hard to see that the CDC is in anti-panic mode, and trying to control the impending backlash against them, spitting out nonsense like - "the immediate risk is low" - translation - soon the risk will be pretty high, but we want you to feel everything is fine.

Edit:
i) Increased exposure leads to increased severity of illness and death. Hence all the young healthy doctors that statistically shouldn't be dying, but are. Even with a bad mask, not being exposed to the full payload is better than nothing.

Sad that everything I wrote was pretty obvious and true, but not (re)discovered until months later when the CDC decided to stop lying.

The public shouldn't trust them, you should only trust what the studies conclude sprinkled with some common sense. That's why when Desantis tells you everything is fine and refuses to release data, you should expect that something is wrong. He can't be caught lying if there's no data to prove him wrong.

Not at all. Usefulness of masks wasn't debatable (though there was an argument about it causing increased hand contact with face for people unaccustomed to wearing masks). The point I was making with my post was that at this time (I am guessing that) very few remember that there was guidance saying not to use masks.

The argument is that there aren't enough cases in NJ to warrant any mask usage at all, and by pushing this mandate now, it increases the chance that it will be ignored in a few weeks when it will actually be necessary.

In actuality, this doesn't at all deny gravity, and is probably fully in-line with current astrophysics. The Alter Rebbe isn't saying that gravity doesn't exist, he's saying that attributing not falling off the face of the earth on the other to gravity is the wrong answer. What the Alter Rebbe is saying is that the entire premise of question is wrong, as there is no real upper and lower side to earth.

Not sure what detailed specifics you're looking for, when it's right there in front of everyone's eyes to see. The "chidush" is that he is drawing the physical conclusion from a metaphysical (I'm not sure if that's the right term, but I didn't want to use ruchnius, as I'm not sure that's the right term either, maybe @Freddie can help) concept. In the physical world, a circle has no beginning or end, and a sphere has no top or bottom, as all sides are the same. If I understand correctly, the Alter Rebbe is saying that the reason the laws of physics are such in regards to spheres, is because they draw their physical existence from the metaphysical concept of Igulim which have no top or bottom (i.e. there's no higher or lower level within an igul).

This article focuses exclusively on the efficacy of mask wearing as *protection* but doesnt even discuss the efficacy of masks as far as transmission *to others* (which would obviously be the point of a mask mandate). Oh, and for protection? He concludes that at risk people (health care workers, the elderly) *should* most definitely be wearing masks *as protection*, and (surprise, surprise!) isnt worried about all of the terrible effects on health that masks are supposed to be causing.

No, people dont just wear masks without thinking. There are many reasons you would see someone in a car with a mask. But if everyone *would* wear masks without thinking wed all be a lot better off.

You clearly missed the purpose of his piece. There are no consequences the other way- he is concerned about the lack of PPE available, but a homemade mask wont cause that and will protect others as well. There is absolutely a preponderance of hard evidence that mask wearing protects others. Its not in dispute by any actual scientists or doctors. Seemingly masks protect the wearer as well, but there is *less* proof and it is *less effective* in that way.

Here's a reason not to wear a mask - if someone has antibodies and according to "studies" the antibodies seem to fade after a few months than maybe constantly getting exposed to the virus will keep the antibodies from disappearing! Like a booster shot - there are multiple articles out there very wary of any vaccine as the vaccine will wear off just like we're seeing with antibodies...

Thats a nice explanation. Shame theres zero scientific backing to it. Because that would mean constantly getting reinfected. Which is sort of the point of masks, to prevent infections.

Although I agree if you have antibodies you can make a strong argument not to wear a mask.

Thank you - I wish I knew exactly how these Antibodies work. When you get exposed to the virus does your body completely repel the virus or does it fight it a bit - strenthing the antibodies...

To help bring consistency across stores and clubs, we will require all shoppers to wear a face covering starting Monday, July 20. This will give us time to inform customers and members of the changes, post signage and train associates on the new protocols.

WALMART-  The ambassadors, identifiable by their black polo shirts, will work with customers who show up at a store without a face covering to try and find a solution.
 
SAMS CLUB- At Sams Clubs, associates at the entrance will follow the same process with members, politely reminding them of our requirement to wear a face covering when shopping with us. Complimentary masks will be provided if the member doesnt have one. Or members can purchase masks in the club.

A few observations:

1. There's no mention of the difference between covering the nose or not. The images seem to indicate almost no excretion from the nose.

2. How meaningful is this study if it only shows the effects 5cm away? How about a more normal 50cm away, which would probably be the minimum distance between the faces of two people facing each other.

Agreed. A mask which doesn't filter droplets and aerosols but slows their velocity to prevent them from traveling far or staying airborne is also a very significant benefit.

I stand corrected. So based on my non-scientific observation, the images seem to illustrate the effects about 15cm-25cm out. I would argue that most face to face interactions are at a greater distance (at least double), and even at the shown distance, it seems like even with the lowest quality mask there are very few droplets, if any, that reach the 25cm range.

Are there any masks with "reverse" valves that lets you inhale unfiltered and fresh air and only filters out exhalations (droplets etc).

I'm asking as someone who:

- has a beard, so most masks won't really help protect me
- is low-risk
- has antibodies
- has a recent negative test
- only wears a mask when asked to (indoors within 6 feet, or on a plane etc).

This would let me breathe fresh air while protecting those around me on the slim chance that I have Covid...

GIYF and comes up with https://www.nejm.org/doi/full/10.1056/NEJMp2006372

But TBH what really made me post this was the phrase "a reflexive reaction to anxiety over the pandemic". I think this is very profound and might be indicative of many if not most or all government reactions to any hint of crisis, be it health, law and order, finance, etc. etc.

I need to think this through, but my initial thoughts are that policy moves are one of two kinds - either a power grab or a reflextive reaction to anxiety over a crisis (or hint thereof).

June 3 follow-up from the authors of that letter: https://www.nejm.org/doi/full/10.1056/NEJMc2020836 (https://www.nejm.org/doi/full/10.1056/NEJMc2020836)

TO THE EDITOR:
We understand that some people are citing our Perspective article (published on April 1 at NEJM.org)1 as support for discrediting widespread masking. In truth, the intent of our article was to push for more masking, not less. It is apparent that many people with SARS-CoV-2 infection are asymptomatic or presymptomatic yet highly contagious and that these people account for a substantial fraction of all transmissions.2,3 Universal masking helps to prevent such people from spreading virus-laden secretions, whether they recognize that they are infected or not.4

We did state in the article that wearing a mask outside health care facilities offers little, if any, protection from infection, but as the rest of the paragraph makes clear, we intended this statement to apply to passing encounters in public spaces, not sustained interactions within closed environments. A growing body of research shows that the risk of SARS-CoV-2 transmission is strongly correlated with the duration and intensity of contact: the risk of transmission among household members can be as high as 40%, whereas the risk of transmission from less intense and less sustained encounters is below 5%.5-7 This finding is also borne out by recent research associating mask wearing with less transmission of SARS-CoV-2, particularly in closed settings.8 We therefore strongly support the calls of public health agencies for all people to wear masks when circumstances compel them to be within 6 ft of others for sustained periods.

June 3 follow-up from the authors of that letter: https://www.nejm.org/doi/full/10.1056/NEJMc2020836 (https://www.nejm.org/doi/full/10.1056/NEJMc2020836)

TO THE EDITOR:
We understand that some people are citing our Perspective article (published on April 1 at NEJM.org)1 as support for discrediting widespread masking. In truth, the intent of our article was to push for more masking, not less. It is apparent that many people with SARS-CoV-2 infection are asymptomatic or presymptomatic yet highly contagious and that these people account for a substantial fraction of all transmissions.2,3 Universal masking helps to prevent such people from spreading virus-laden secretions, whether they recognize that they are infected or not.4

We did state in the article that wearing a mask outside health care facilities offers little, if any, protection from infection, but as the rest of the paragraph makes clear, we intended this statement to apply to passing encounters in public spaces, not sustained interactions within closed environments. A growing body of research shows that the risk of SARS-CoV-2 transmission is strongly correlated with the duration and intensity of contact: the risk of transmission among household members can be as high as 40%, whereas the risk of transmission from less intense and less sustained encounters is below 5%.5-7 This finding is also borne out by recent research associating mask wearing with less transmission of SARS-CoV-2, particularly in closed settings.8 We therefore strongly support the calls of public health agencies for all people to wear masks when circumstances compel them to be within 6 ft of others for sustained periods.

The video was posted on youtube... by Donald Trump. That's why he's relevant. It's intended to own the libs and gain support, and to make people feel better about voting for him. But intelligent viewers might realize that the damage caused Pelosi's hypocrisy pales in comparison to the damage caused by his incompetence.

Of course Pelosi was stupid and hypocritical. But people watch this and think Trump is on the right side of the coronavirus and Pelosi is on the wrong side. And that's what bothers me - it takes so much blindness and delusion and just general disbelief of reality to believe that's the case.

Wearing a mask. Much has been said pro and against, however this is not a political/social issue but a medical one. It is clear that if all parties wear masks at all times in public there will be reduced spread of the virus. It is also true that for many, mask wearing is bothersome and seems pointless. Presented with rational guidelines perhaps smart mask wearing will take place.
All those that are vulnerable should wear a mask when in any public forum (except when walking down a quiet sidewalk, where the possible obstruction to vision may outweigh the minimal benefits). In addition to whatever degree the mask is protective, it also serves as a sign to others that you are vulnerable.
Everyone, including those who have had the illness, when in close social contact with strangers (not immediate family) should wear a mask. This is most helpful in the event that one is unbeknownst to themselves possibly infectious.
In any crowded indoor setting where close social contact is unavoidable, one should wear a mask. At simchas and large gatherings of people, even outdoors, masks should be worn.
One who is in quarantine but who needs to go out for essential purposes must be strict with themselves to wear a mask at all times in public, and not engage socially with others.

If anyone is in close contact with someone who is considered contagious according to the above criteria, they need to quarantine. (Close contact is defined as within 6 feet for 10 minutes, regardless of mask use.) Quarantine means to be kept separate from other people, and lasts for 14 days from the last point of close contact with the contagious person. Testing negative does not allow one to discontinue quarantine. If one were to test positive while in quarantine, they would follow isolation guidelines above.

Miriam Rivka (Adler) Rozen 1 WEEK AGO EmailPrint Reply
While I dont generally read the Mishpacha Magazine each week, I have to say, that when I do have time to read, I enjoy it and I feel that it is an excellent publication. Like many people, the first feature I turn to, is The Kichels. Unfortunately, the comic from two weeks ago didnt leave me chuckling; I felt offended and angry. I am referring to the episode where not one character was wearing a mask correctly.
I have been an acute care nurse in a really lovely community hospital in Valley Stream, Long Island, NY for over twenty years. Most of those years, I have worked, and continue to work in critical care (ICU). My hospital was one of those in the New York metropolitan area that witnessed some of the worst COVID numbers. When I hear statements like, oh, its political, or its a hoax, or they starved my family member, and they didnt let us visit, those rotten nurses/doctors I think of one thing: We have surveillance cameras on us constantly. Pull all of the hospitals surveillance cameras and publicize them for the world to see what actually happened in the hospitals during the COVID-19 pandemic. Allow me to give you a glimpse.
The average 12-hour shift became a 14-hour shift. Nurses didnt go to the bathroom, nurses didnt eat, nurses didnt sit, and nurses often couldnt find time to have a drink of water. I stopped bringing lunch to work, because I found myself throwing it away, uneaten, at the end of my shift. Nurses literally spent all day keeping people alive; monitoring continuous vital signs (temperatures, blood pressure, pulse and heart rate and rhythms, respirations, and oxygen saturation), and treating them almost as often, treating the sick with multiple lifesaving drips (the average patient had 5-8 life-supporting IV medications that needed to be changed very often), monitoring blood sugars, monitoring ventilator (respirator) support, drawing blood and lab work and then treating abnormal values, and, of course, speaking to families and providing emotional support.
The ICU that I work in has 16 beds. During the pandemic, there were over 30 patients each day. Nurses who usually cared for two critical patients each day had to care for three or four patients at a time. That lasted for about six-seven weeks. Not to mention the additional 10 or so critical patients who were in the ER each day because the main ICU didnt have enough beds to hold them.
Most of the days I was assigned to work in a makeshift ICU. It was like a field hospital. Supplies were scarce. PPE (personal protective equipment) was scarce at times. Our N-95 masks that we were accustomed to throwing away after previously going into a negative pressure room (those used for TB and other airborne diseases), were suddenly a rare commodity. Even if one broke, our manager told us to staple it back together.
I remember wondering if we were all going to be dead in a few weeks, considering that it seemed that the Malach HaMaves had literally set up shop in my unit. Could you, dear friends and readers, understand that thought? You surely cannot imagine what life was like for the healthcare workers who went to work each day to care for your family members. We put our lives on the line.
Nurses asked shailos about pikuach nefesh. Were they allowed to pick up extra shifts, when asked, to help out their strained colleagues? I have a colleague who did not see his infant for 51 days. Another colleague, a young, new nurse, moved out of her high risk parents home. We worried that we were bringing the disease home to our children, spouses, siblings, and parents. Many nurses wrote wills for the first time.
Oftentimes, in the past few months, as I walked in my neighborhood with my mask, I wanted to wear a sign that said, I worked in the ICU (or ER) yesterday. Would you want to inhale my germs? My mask protects you and your mask protects me. There is nothing comical about this. I work with many talented doctors who live and breathe a website called up to date. They read every single published report related to COVID-19. Even they are shocked at the virulence of this disease. And these experts advise to continue wearing masks and maintaining social distance.
In addition, I feel it is our ethical and moral obligation to be mekadesh sheim Shamayim by doing the very small act of wearing a mask. When I am standing and caring for a patient, I am embarrassed to see and hear news reports about the new COVID cases coming from our communities, from these super-spreader events like chasunos and other such gatherings. How am I to respond to my fellow nurses and doctors when they question me about our communities poor COVID habits?
Why does my family have to endure mask shaming? Why have my children had their masks pulled off their faces? Do the rules and laws only apply to me? Come on, Klal Yisrael, we can do this. Its Elul. Can we just wear our masks and practice social distancing? Can we just do it to protect our healthcare workers who have to wear masks for an entire shift multiple times during the week?
I believe we can. We can put our personal yegios aside, we can put our discomfort aside, and we can say we love our brothers and sisters in Klal Yisrael, and we are doing it for them. And we can do our part in preventing the spread of COVID-19.
Wishing everyone a Kesiva Vechasima Tova and a Gut Gebentsht Yahr,

I just don't understand why it's seen as a joke.

Im the last person to conform, I mean when my father said do this, I didn't, when he said don't do it, I did.

The author aharon applebaum wrote a book called badenheim 1939. I feel like "the grand budapest hotel" is based on the book.

In the book, he describes the anti Jewish laws and the German authorities as "the sanitation department"

Masks are, in my opinion, the best way for society to function at this time.

It's not a test if we, as a society, will just do what we are told.

I certainly understand the opposition by people in that sense but getting lazy?

If anyone is in close contact with someone who is considered contagious according to the above criteria, they need to quarantine. (Close contact is defined as within 6 feet for 10 minutes, regardless of mask use.)

The Gedaliah Society, in conjunction with Dr. Rosen

WRONG WRONG and WRONG AGAIN. The CDC does not specify the implications of mask use in regards to the need to quarantine.

MD Anderson states explicitly:

"What constitutes close contact and what constitutes exposure to the coronavirus?

Close contact to COVID-19 occurs when you are within six feet of someone who is showing symptoms of COVID-19, for at least 15 minutes, when neither person is wearing a mask, and the infected person later tests positive for the coronavirus...If either or both individuals were wearing face masks, it is not considered exposure."

WRONG WRONG and WRONG AGAIN. The CDC does not specify the implications of mask use in regards to the need to quarantine. If the Gedaliah Society or the vaguely identified Dr. Rosen made this statement, they/he are highly suspect on all their guidance.

1) Dr. Rosen has been a community doctor in CH for decades. He's is very well known in their circles. The Gedaliah Society and Dr. Rosen are giving advice to that specific community, and that community alone.

2) I'd put Dr. Rosen's track record with this pandemic up against the CDC's in a heartbeat. The CDC has been a political pawn from the very beginning. It's been very well documented, culminating with a FOX News report the other day confirming that all CDC messaging is run through the White House now.

3) It is very likely that the CDC's guidelines are assuming the use of N95 masks. Most masks that people use are not enough to completely guarantee that transmission will not occur when one sustains contact in close quarters with a contagious individual.

Wrong! The guidelines defining 'close contact' are from MD Anderson, not the CDC. It is purely wishful thinking to suggest that general guidelines presented on a World-renowned medical institution's website refers to N95 masks when the majority of the general public does not use N95s.

Exactly. They as all of us know that there are different levels of protection provided by masks and how they are worn. They provide "blanket guidelines", just as Johns Hopkins and Mayo Clinic does on their websites, meant for the general public doing things the general public does. There is no logical reason to assume they are only referring specifically to N95 wearers.

For the record, 10 minutes within 6 feet is in line with UPenn's definition of medium-risk exposure. They also define a high-risk exposure as being "exposed to aerosolized secretions from an infected patient without recommended respiratory protection."

We can dance around this forever, but they still aren't wrong in the guidance. Not that I'm a fan of CDC guidelines, but this is buried as an asterisk on their site:
Quote
Data are insufficient to precisely define the duration of time that constitutes a prolonged exposure. Recommendations vary on the length of time of exposure, but 15 minutes of close exposure can be used as an operational definition. Brief interactions are less likely to result in transmission; however, symptoms and the type of interaction (e.g., did the infected person cough directly into the face of the exposed individual) remain important.

If the Gedaliah Society prefers to issue guidance that leans towards the more cautious side, that doesn't warrant a

According to modelling conducted by Fugaku, the worlds fastest supercomputer, the disposable medical masks now almost ubiquitous on streets in many countries across the world constitute a far more effective barrier to respiratory droplets than cotton varieties, The Telegraph reports.

Cotton masks blocked just 80% of spray emitted when a person inside coughed, and the figure dropped to around 60% when smaller drops were analyzed. In contrast, the disposable masks studied blocked nearly all droplets and around 90% of smaller droplets, most of which escaped through the gaps around the edge of the mask.

Fugaku can perform more than 415 quadrillion computations a second.

Depends on which ones you get. Many will say on them "for non-medical use" although they may be of the same quality. For regulation and cost purposes they are not certified as such. You can do little tests like try blow out a candle, see how much water it can hold, and other tests to see how good the mask is.

Many are pretty good for medical usage, in fact some of the masks I imported had better filtration than medical masks. But all the 3 ply masks aside for the big brands will say "not for medical use" due to Chinese export regulations.

So I have done a little experimenting with this because I give a daf shiur and lain during the week and on Shabbos and YT, so for what its worth here is what I found:

Surgical masks are the lightest but they dont stay on for an hour long shiur or for seven aliyos on Shabbos.

Cotton masks can be a bit stifling, but allow me to project better than KN95's

KN95's dont allow me to that loud, but give the most room to breathe and keep me cool because of the duck bill shape.

So I lained both days RH and what I did was I wore the KN95, then the cotton mask for laining and then immediately switched back to a KN95 after I finished laining. The cotton mask allowed me to amplify and I had the immediate cooling when done.

I do wear the KN95 when giving daf, but it seems to be less of an issue for people to hear me since unlike when I am laining, I face the tzibur when giving shiur.

Finally - my AC is a teacher in Beis Yaakov and she uses a mask guard under a cloth mask which keeps the mask from stifling her, but also does not ruin the seal.

Agreed to an extent. From what it seems, there was no real danger / threat to the officer, and there was another one standing idly on the side. When there's 2 against one and no danger, I don't think tasing was necessary.

A) It isnt clear what role aerosols play in transmission, but its certainly not the only way the virus is transmitted. Large respiratory droplets play at least a large role, if not the clear primary role (the current assumption). Distancing helps, but of course masks help as well.

B) Just because some of the aerosolized vapors came through doesnt mean some werent filtered. Even in the video, you can clearly see the difference between the medical/surgical masks and the cloth ones. The less virus that comes out, the less the ability to infect. Even if the masks just lower the momentum of the particles escaping (causing the droplets to fall to the floor or dissipate sooner, which is one of the reasons masks are recommended) but dont actually prevent them from getting out, the potential to infect others is dramatically reduced.

C) Not all aerosols are created equal.

Masks and distancing *reduce* but do not *eliminate* transmission. Thats why people should wear masks, but not rely on them completely.

True. The headline wasnt false. But it was a drop misleading (like many/most headlines are).

If she would have said Wearing face masks is political theater, the headline would have summed it up accurately. But what she said (and what her intentions were) was that this specific instance of removing (and by implication, wearing) a face mask is for political theater (as which moment she removed her mask didnt have a genuine health consideration).

In summation: The headline suggests she calls face masks political theater (suggesting that is their purpose, not public health). In truth, while she said those words in that instance, its not what she meant.

2 questions -

If you can please link 2 or 3 real articles (not political) with studies.

2. Before the CDC reversed their guidance, & recommended masks, was the general consensus among the medical community that the CDC was wrong? Or they were all following the CDC? (I do remember there being a lot of talk here about the CDC being wrong but Im wondering if doctors were all going against the CDC as well)

(I do remember there being a lot of talk here about the CDC being wrong but Im wondering if doctors were all going against the CDC as well)

To answer your question: The medical establishment/doctors take guidance from the CDC, so they did not advise communal mask wearing. However, any individual doctor would have told you to wear a mask if you needed extra protection, and would have required a COVID+ person to wear a mask if they left the house.

The question wasnt whether masks are beneficial in slowing person-to person transmission of COVID. It was whether the benefits of communal mask wearing would outweigh the costs at the time.

There also was the concern of fomites, which has since been shown not to be the main source of spread. Because person-to-person transmission now known to be the main source of spread, the benefits of mask wearing (which reduce person-to-person spread) outweigh the potential hazards (which raise the potential for fomite spread).

NOTES:

1) A large part of the CDC guidance was predicated on the assumption that COVID-19 wasnt widely seeded, so communal wearing of face masks was unwarranted and didnt offer as great a benefit. Contact tracing was considered much more important.

2) They claimed that asymptomatic/pre-symptomatic spread wasnt proven, which would effectively negate the largest benefit of masks, although it was well known at that point as @yuneeq often reminded us.

3) The crux of the guidance was that masks were being diverted from medical personnel, as there was a severe shortage of PPE, for use in community settings where the potential benefit was unknown. This could have had terrible overall implications for medicine. Later, they encouraged homemade masks, circumventing this issue to an extent while allowing for mask usage.

4) It is universally acknowledged that it was a mistake. They were criticized at the time as well. Note that the quote from @aygart is from March, before the CDC reversed guidance.

5) In the earliest days it wasnt clear what played a greater role in transmission, fomites or respiratory droplets/aerosols. That debate was settled in April with more information, showing that fomite transmission was relatively rare.

Please explain, why exhaling smoke is different than exhaling air?

Irrelevant question. It was never a question if masks completely blocked air, obviously they don't block air going in/out or else we wouldn't be able to breathe at all.
The question is if masks block the droplets that naturally disperse when speaking, yelling, coughing, or just breathing. And the answer is a resounding yes.

I have not seen the R' Chaim Kanievsky letter, but Arutz Sheva had a summary which included this sentence on masks which I bolded:

Quote
Ahead of the Sukkot holiday, leading rabbis Rabbi Haim Kanievsky and Rabbi Gershon Edelstein released a letter giving instructions on communal prayers and conduct during the holiday in light of coronavirus.

"The warden of the synagogue will see to it these days, to ensure the possibilities of prayers as much as possible in the open space of the synagogue courtyards, etc., and the reward for all those who can help with this in other places is great.

"During the entire holiday, one must not be a guest for meals etc., and those at high risk, including the elderly, should be very careful, " the rabbis noted.

"One of the things that is very protective against infection when among people is wearing masks, and their benefit is very great and should not be taken lightly."

"One of the mitzvot of Sukkot is joy and everyone should be very joyful on the holiday, and actions should be taken to make one's family and children happy and to create a pleasant atmosphere at home."

The rabbis noted that after one puts in the necessary effort, the obligation remains to "believe and trust in Hashem, Blessed be He, who is the leader and overseer, and the virus will harm nobody if it is not decreed from above, and we should take advantage of the upcoming holiday to strengthen belief."

"The fundamental principle: the Torah protects and saves, and we must grow stronger in studying Torah, and through the strength of the Torah we will be saved from any sickness."

Quote
The head of the Merkaz Harav yeshiva in Jerusalem, Rabbi Yaakov Shapira, calls on the citizens of Israel, including members of the religious Zionist community, to obey the guidelines of the Health Ministry, wear masks, maintain social distancing and avoid gatherings.

"We are approaching Simchat Torah which is the culmination of all the festivals," he said. "The purpose of Simchat Torah is to say the verse 'You are instructed to know that the Lord is G-d and there is no other besides Him.'"

"Everything that the world is currently undergoing renovations, all because G-d is alone, he knows when there will be a cure for this plague," he added. "But the Torah requires of you to protect your lives very carefully."

"To celebrate Simchat Torah in the present circumstances, even though it is not easy, we should look at the yeshiva as an example. There are no students now, and this does not bring us any joy, all the moreso during Simchat Torah. But the Torah tells us to be joyful during the holidays. We should rejoice with the Torah, and the Torah should rejoice with us; The Torah will rejoice with us if we keep to the guidelines. And you will guard your lives very carefully.

"Do not get too close to each other, put on the masks," said Rabbi Shapira. "I am not a doctor, but we are commanded in the words of the Torah to do everything so that no one will get sick, and so that whoever does get sick should return to us quickly. So that the people of Israel themselves will return to us soon."

It's not THE cause, but you can't argue that it's not a factor. In fact, you'd be hard pressed to find someone with Covid walking around mask-less in a society where masks are the norm. Which is another huge benefit to masks.

You won't get an argument from me on that. @avromie7's theory is that the reason for most of the spread is COVIDiots walking around without a mask while infected. We're obviously talking about people and places where isolation isn't happening. My point is that if the general population was all wearing masks, those COVIDiots would be, too, cutting down on the spread tremendously. Just another reason for mask mandates.

Statistically significant correlation is actually considered valid supporting evidence, although not final proof. It helps shift the burden of finding a valid third variable to the party denying the causation. Of course, finding statistically significant results to support a hypothesized finding is very different from picking one significant correlation out of a data table.

With enough instances of a correlation, its likely that many would consider it proof pending a clear and obvious reason for dismissal.

What is a demonstrable third variable that applies to all locations that adhere to to masks/SD vs. similar and close locations that dont behave this way that would explain the discrepancy in case load, and what makes you believe that variable is as or more likely than masks/SD?

I don't have hard data, and it would be difficult to come by. I think it's safe to say, people who wear masks are definitely isolating when COVID+ and people who won't isolate are definitely not wearing masks. (Most of the people I know are in the middle, not wearing masks but isolating if COVID+)

Repost and ere is a response

A) It isnt clear what role aerosols play in transmission, but its certainly not the only way the virus is transmitted. Large respiratory droplets play at least a large role, if not the clear primary role (the current assumption). Distancing helps, but of course masks help as well.

B) Just because some of the aerosolized vapors came through doesnt mean some werent filtered. Even in the video, you can clearly see the difference between the medical/surgical masks and the cloth ones. The less virus that comes out, the less the ability to infect. Even if the masks just lower the momentum of the particles escaping (causing the droplets to fall to the floor or dissipate sooner, which is one of the reasons masks are recommended) but dont actually prevent them from getting out, the potential to infect others is dramatically reduced.

C) Not all aerosols are created equal.

Masks and distancing *reduce* but do not *eliminate* transmission. Thats why people should wear masks, but not rely on them completely.

A new study by Simon Fraser University (SFU) researchers has found clear evidence that wearing a mask can have a significant impact on the spread of COVID-19. The researchers, from SFUs Department of Economics, have determined that mask mandates are associated with a 25 per cent or larger weekly reduction in COVID-19 cases.

The finding of their study, still in preprint and not yet peer-reviewed, conclude that mandating indoor masks nationwide in early July could have reduced the weekly number of new cases in Canada by 25 to 40 per cent in mid-August, which translates into 700 to 1,100 fewer cases per week.

The study analysed the impact of mask mandates that were implemented across Ontarios 34 Public Health Units (PHUs) over the course of two months.

Researchers compared the results of PHUs that adopted mask mandates earlier to those that adopted mandates later. They determined that, in the first few weeks after their introduction, mask mandates were associated with an average weekly reduction of 25 to 31 per cent in newly diagnosed COVID-19 cases, relative to the trend in mask mandate absence, in July and August.

A further Canada-wide analysis with province-level data found a significantly negative association between mask mandates and subsequent COVID-19 case growth up to a 46 percent average reduction in weekly cases in the first several weeks after adoption.

These results were supported by additional survey data that showed mask mandates increase self-reported mask usage in Canada by 30 percentage points, suggesting that the policy has a significant impact on behaviour.

Jointly, these results suggest that mandating indoor mask wear in public places is a powerful policy measure to slow the spread of COVID-19, with little associated economic disruption in the short term.

The study also found that relaxed restrictions on businesses and gatherings (including retail, restaurants and bars) were positively associated with subsequent COVID-19 case growth a factor that could offset and obscure the health benefits of mask mandates.

The most stringent restrictions on businesses and gatherings observed in the data were associated with a weekly decrease of 48 to 57 per cent in new cases, relative to the trend in the absence of restrictions.

The study authors note that while the results are significant, their sample period does not allow them to definitively say whether the effect of mask mandates persists or weakens beyond the first few weeks after implementation. However, they conclude that, combined with other policy measures, mask mandates can be a potent policy tool for slowing the spread of COVID-19.

I enjoy reading medical news and studies. One of the (many) calamities that came out of this pandemic is that every Chaim Yankel now thinks that he's Meilich Firer or Shuki Berman, and he's fluent in medical literature and research.

Anyone who believes that years of study and experience can be replaced by the reading of some newspaper items and a quick perusing of medical studies is deluding themselves. I overhear laypeople in shul espousing strong opinions about things related to my profession, and I just sit there and nod - while inside I'm laughing. They find a nugget of truth and extrapolate hilariously from that; they don't even know what they don't know. So to think reading a couple news articles and/or medical studies as a layperson can somehow make one more knowledgeable than a doctor is laughable. A doctor knows how to parse medical studies and data in ways that a layman cannot.

For instance, see the Gell-Mann amnesia phenomenon as an example of how using items written for a layperson as a replacement for professional advice is foolhardy. https://www.epsilontheory.com/gell-mann-amnesia/

Its actually that simple. Theres a global pandemic with thousands of people dying daily around the world. If a doctor had a technique that was actually working it would likely be discussed elsewhere.

I think a lot of people are inclined to agree that its the latter but my personal opinion is to just wear them anyway. No point in fighting city hall right now over this.

Sorry, this is not nice. He put a link to a study done putting mask wearing in question and I don't see his question being derogatory or cynical. We know that everyone has varying opinions on mask wearing and all are entitled to theirs but let's try to be respectful.

Not to mention the fact that they were only studying whether masks protect the wearer from contracting the virus, not whether they protect others from a mask-wearing infected individual. Or the fact that they explicitly say they're studying whether wearing a mask in settings where others generally aren't wearing masks is effective, as opposed to whether large-scale mask wearing is effective.

I agree that this study may not prove anything at all and am not advocating not wearing masks (on the contrary I believe everyone should wear, especially indoors) but that response still remains disrespectful.

It has nothing to do with how I (or you) feel about vaccines, it was the tone of your response that I felt wasn't called for. People are entitled to their opinions about vaccines even if I feel they're totally wrong and their proofs are bogus but I will try to show them that in a respectful manner. But that's just me.

1) The study was rejected for publication by the 3 biggest medical journals. Those journals regularly publish studies which contradict current medical consensus.

2) Saying that masks are a construct of politicians and laypeople is a conspiracy theory with zero basis. Respectfully arguing its merits does nothing more than validate the opinion, which is a huge mistake, IMO.

There is an argument to made that such data is what matters to evaluate mask mandates. What matters is not what happens when worn properly but rather what happens the way the compliance happens in the real world.

The flip side of that is that it only shows what happens when a small number of people where masks by suggestion, not what happens when large percentages of the population where wear masks by mandate.

The study's authors have said it publicly. It's been an ongoing saga for a while now. The study was ready for publication in October, but they couldn't find a journal that would publish it. The authors refused to discuss the study or its findings until it was published, and they wouldn't say why they were rejected from NEJM, JAMA, and The Lancet, other than "they weren't brave enough."

Absolutely. But to frame it as though masks don't work, is false. There are actually people out there who do wear masks properly, and it isn't right to discourage them from doing so.
In fact, this is likely a reason the CDC didn't recommend masks originally, because they felt there wouldn't be much benefit if most people dont wear them properly. Ironically, the same people who harp on that flip-flopping as "proof" that masks don't work, will run around with this study as well, not realizing/ignoring that it is lack of proper usage which was the cause of both. (And even more ironically, in my experience, it's usually the same people who don't wear masks properly, even when they do wear them)

I believe the infection rate is way too low to make good conclusions from this study, only 2% infected over 2 months is really low whether masked or otherwise. It suggests that there's an overarching cause for the low infection rate, it may have to do with social distancing norms, which the researchers also recommended for everyone. In one study it shows many get infected from a family member or while dining, so as PlatinumGuy suggested, masks won't help you when you're at home or in other places not wearing a mask. What would be more interesting is a study showing how masks perform in non-socially distanced environments.

Additionally, the study itself acknowledges that it doesn't make an "assessment of whether masks could decrease disease transmission from mask wearers to others."

I am not arguing or fighting, and definitely not seeking concessions. I just posted comments of fact in response to Dr. Griffin's tweet. As a person who doesn't regularly wear a mask, I am at the mercy of whatever is available at the exact moment (I've also tried buying several, and found none that I was comfortable with, and am not spending time and effort trying on different types to find what is least problematic).

What type of mask? Was he indoors for extended periods of time with others? (Masked or nonmasked)
Everyone has their own idea of being careful. The question is if it's the right type of careful.
 That being said, I think everyone knows people who are careful in general who caught it. Remember, they can always catch it at home. A strong chain with a weak link can still break.
(What also has to be taken into account is the percentage of those who are careful who catch it vs those who aren't careful who catch it)

Wearing a mask around maskless people should at most only slightly prevent COVID if you're not also wearing eye protection. Though wearing a mask will decrease the viral load/severity of disease. Not sure why this is never mentioned.

I really haven't seen eye protection mentioned at all. In the beginning of COVID there was a lot of discussion how the virus can enter from the nose, throat, and eyes, but for some reason all the mask discussions and articles I've read since then have never mentioned the eyes.
