Anti-mask protests

Just to add that as well as the Brownian motion, there's another reason the 0.1 micron virus can't pass through the larger 0.3 micron mask pores.

It's because 0.1 microns refers to the size of the virus naked, as it were. It doesn't travel naked. It travels enveloped in aerosolized particles which are typically 0.5 to 10 microns in size, or droplets which are larger yet.

 

Exactly. But the lab tests are typically done with particulates that are not aerosolized viruses and still the masks perform well. In real life, even better. I mean, even better, provided that the seal is good and the person wears the mask correctly. In lab conditions one can use mannequins to simulate a face and ensure appropriate seal which is not always the case for the live human. Months ago when this started, I saw a study using mannequin heads. I haven't been able to locate this study again (I didn't save the link). If I bump into it again, I'll post it.

PS - Here is an article about a study that used mannequin heads as well, looking at droplets (not the actual study but an article about it).

It wasn't this one, though. The one I saw was trying to get at mask efficiency to stop viruses and was done before the pandemic.

 

Found another one, using manikins and wet aerosol. Again, it isn't the one I saw months ago. I wish I could find that one, which was even more interesting.

Huffpo? No thanks.

 

What part of this you didn't understand?
"And don't shoot the messenger because it was reported by the HuffPo. I couldn't care less, who reported it. I bumped into it through an aggregator and there are video clips, it's not like it's not factual."
For the record, I also find the HuffPo *very* biased, and me being a centrist, it's not a source I usually consult. But when they have video clips and all, we know that the event did happen. So ignoring it just because of who reported it, doesn't change the reality of what happened.

 

But look, why don't you simply buy a box of better masks? 50 pieces of a truly excellent one is on sale on Amazon for $46, so it's less than one dollar per mask. If you want, let me know and I'll send you a link. Your wife needs to be very careful. Teach her the three rubber bands technique; at least that.



If you and your wife adopt these precautions I'll be very happy.

 

That's the one we use. Between the three of us, a box lasts for about two months. That includes people delivering things where we have to have face to face.

We don't go out. Hardly ever.

We have each other.

 

Huffpo?

No thanks.

 

OK, then, here is a different source, same event (second part of the article; the first part has an idiotic business owner in Florida who bans customers WITH masks from his bar. While he has the right to set the rules in his private business, I wonder how he'll feel about it if an employee or himself get a severe case of Covid-19 or suffers a disabling long-term survivor complicaton.

Good for you! I'm happy to hear it!

 

Thank you very much. I thought it was the cutest thing I've seen all day. "Let me see your dimples!" was almost unbearably endearing.

 

Yeah, sure, very cute, until someone gets seriously sick, then it will be no laughing matter.

 

From : Jim Meehan, MD - General Surgeon

~ A response to people who use the classic fallacious argument, " Well, if masks don't work, then why do surgeons wear them? "
I'm a surgeon that has performed over 10,000 surgical procedures wearing a surgical mask. However, that fact alone doesn't really qualify me as an expert on the matter. More importantly, I am a former editor of a medical journal. I know how to read the medical literature, distinguish good science from bad, and fact from fiction. Believe me, the medical literature is filled with bad fiction masquerading as medical science. It is very easy to be deceived by bad science.
Since the beginning of the pandemic I've read hundreds of studies on the science of medical masks. Based on extensive review and analysis, there is no question in my mind that healthy people should not be wearing surgical or cloth masks. Nor should we be recommending universal masking of all members of the population. That recommendation is not supported by the highest level of scientific evidence.
First, let's be clear. The premise that surgeons wearing masks serves as evidence that "masks must work to prevent viral transmission" is a logical fallacy that I would classify as an argument of false equivalence, or comparing "apples to oranges."
Although surgeons do wear masks to prevent their respiratory droplets from contaminating the surgical field and the exposed internal tissues of our surgical patients, that is about as far as the analogy extends. Obviously, surgeons cannot "socially distance" from their surgical patients (unless we use robotic surgical devices, in which case, I would definitely not wear a mask).
The CoVID-19 pandemic is about viral transmission. Surgical and cloth masks do nothing to prevent viral transmission. We should all realize by now that face masks have never been shown to prevent or protect against viral transmission. Which is exactly why they have never been recommended for use during the seasonal flu outbreak, epidemics, or previous pandemics.
The failure of the scientific literature to support medical masks for influenza and all other viruses, is also why Fauci, the US Surgeon General, the CDC, WHO, and pretty much every infectious disease expert stated that wearing masks won't prevent transmission of SARS CoV-2. Although the public health "authorities" flipped, flopped, and later changed their recommendations, the science did not change, nor did new science appear that supported the wearing of masks in public. In fact, the most recent systemic analysis once again confirms that masks are ineffective in preventing the transmission of viruses like CoVID-

19: https://wwwnc.cdc.gov/eid/article/26/5/19-0994_article

If a surgeon were sick, especially with a viral infection, they would not perform surgery as they know the virus would NOT be stopped by their surgical mask.

Another area of "false equivalence" has to do with the environment in which the masks are worn. The environments in which surgeons wear masks minimize the adverse effects surgical masks have on their wearers.
Unlike the public wearing masks in the community, surgeons work in sterile surgical suites equipped with heavy duty air exchange systems that maintain positive pressures, exchange and filter the room air at a very high level, and increase the oxygen content of the room air. These conditions limit the negative effects of masks on the surgeon and operating room staff. And yet despite these extreme climate control conditions, clinical studies demonstrate the negative effects (lowering arterial oxygen and carbon dioxide re-breathing) of surgical masks on surgeon physiology and performance.
Surgeons and operating room personnel are well trained, experienced, and meticulous about maintaining sterility. We only wear fresh sterile masks. We don the mask in a sterile fashion. We wear the mask for short periods of time and change it out at the first signs of the excessive moisture build up that we know degrades mask effectiveness and increases their negative effects. Surgeons NEVER re-use surgical masks, nor do we ever wear cloth masks.
The public is being told to wear masks for which they have not been trained in the proper techniques. As a result, they are mishandling, frequently touching, and constantly reusing masks in a way that increase contamination and are more likely than not to increase transmission of disease.
Just go watch people at the grocery story or Walmart and tell me what you think about the effectiveness of masks in the community.
If you can't help but believe and trust the weak retrospective observational studies and confused public health "authorities" lying to you about the benefits and completely ignoring the risks of medical masks, then you should at least reject the illogical anti-science recommendation to block only 2 of the 3 ports of entry for viral diseases. Masks only cover the mouth and nose. They do not protect the eyes.

 

The mortality rate of Covid 19 is grossly exaggerated.

 

Pray tell, on what do you base this *opinion*? Evidence, please?

 

Most likely people are not doffing the PPE appropriately. They need retraining. They are probably contaminating themselves when they remove their PPE.

 

~ But wait ! There's more ...

 

~ It means if people in healthcare can't protect themselves property expecting the average person to do so is useless .

 

Yes, we shouldn't buckle up with seat belts because some professional race car drivers die in accidents.
We see the strangest arguments here.
What explains it is much more likely to be, we healthcare workers are repeatedly exposed, and to large viral loads; eventually some of us get it. Can you imagine, though, how many of us would get it, if we didn't wear any PPE?
