Jeff Duntemann's Contrapositive Diary

I’ve been pondering this issue since last fall, waffling constantly about whether I should write about it at all. I was sure that any number of other people would make the point I’m about to make, but I haven’t seen it. Maybe it’s too simple. Maybe people are past caring. I don’t know.

Here’s my point: Consumer-grade masks can’t stop SARS-CoV-2. It’s impossible. But not for the reasons you might think.

First, some background. Surgical masks were originally developed to protect vulnerable patients from pathogens exhaled by doctors. They were not designed to protect healthcare workers from patients. Some people recognized this early on, in memes stating (rather too confidently) “My mask protects you. Your mask protects me.” In a perfect world, that might be true. Such a world does not and cannot exist.

The key word here is perfect.

In order to be effective, a mask must meet these requirements:

1. It must be made of a material allowing the flow of air while seriously restricting the flow of droplets and aerosol virus particles. Such masks are uncommon. The only ones I know of are N95 masks, without exhalation ports. (Exhalation ports render an N95 mask pretty much worthless, as this study showed.) And I’d just as soon reserve N95 masks for front-line healthcare workers.
2. A mask must fit close to perfectly. I don’t know how anybody expects one mask design to fit all the infinite varieties of human faces. Fit often requires that the mask straps be very tight, so tight as to be nasty uncomfortable. A couple of loose straps over your ears won’t do it, especially if your face is unusually long or wide.
3. The mask must be worn perfectly. If adjusted for comfort, even a perfectly fitted mask will leak like a sieve and ceases to be effective.
4. Touching the filtering medium of your mask is a no-no. If you’re in an area with aerosol virus particles floating around, those particles will accumulate on the outside of the mask. Touching them transfers them to your fingers, which can then easily transfer them to food or tissues.

The primary failure mode for masks is leakage. When the whole mask fetish first became a thing, we bought some masks and I did some experimenting. I put a mask on as best I could, dipped a finger in a glass of water, and held the wet finger around the edges of the mask while I breathed normally. I could easily sense jets of air at several places around the edge of the mask, no matter how I adjusted it. These jets did not pass through the mask material, and if the wearer is contagious, the aerosol virus particles will be sent in several directions with significant force. I was surprised, in fact, at how much force was behind the jets from even normal breathing.

Think about jets of air for a moment. Even a tiny amount of air will move quickly if forced through a small hole or gap. Those jets leaking around the edges of your mask will carry aerosol viruses a long way. Sure, droplets quickly fall to the ground within the standard distance of six feet. SARS-CoV-2 travels as both droplets and as aerosols. Droplets are big enough to be trapped by the mask’s filtration medium. Aerosols are so small that most go right through it, absent expensive materials like those used in N95 masks. Cloth masks depend on the nature of the cloth. Cheap surgical masks barely stop them at all. Woodworking masks are completely worthless. Hold that thought; I’ll come back to it.

I’ve found some interesting videos. In this first one, a woman takes a hit off her vapestick, puts her mask back down, and then exhales. She immediately blows two jets of smoke right into her eyes, and then starts choking. Bad idea. The takeaway is that smoke came out the edges of her mask in a hurry. Obviously the mask was not being worn correctly. Hold that thought too; I’ll come back to it.

Here’s another, better video, in which a man wearing several types of masks inhales from a vapestick and exhales while wearing the masks. (I can’t tell whether he’s wearing the masks correctly or not, though it looks correct to me.) Smoke or vapor (I’m not especially familiar with the technology) streams out from the edges of the mask on every side. The smoke or vapor is there there simply to help you visualize how leaky cheap masks are. Clearly, my mask doesn’t protect you, and your mask doesn’t protect me. (The video was originally posted on YouTube several times, and taken down every time. It’s now on BitChute. The Powers obviously don’t want you to see failure modes in enforced conventional wisdom.)

Even a high-quality mask will leak around the edges, especially if you have a nonstandard face. We needn’t mention gaiters, which have no mechanism for preventing significant jets through the gaps on either side of your nose.

Now, I told you all that to tell you all this: Suppose a high-quality, perfectly fitting mask worn perfectly traps a significant number of aerosol particles. Here’s the extra-large economy-sized question:

How do you guarantee that all mask wearers are wearing effective masks that fit well and are worn correctly?

We all know the answer: You don’t. Masking is a collective exercise. It’s gotta be almost everybody or it might as well be nobody. There is no enforcement mechanism that will render a mask-wearing public immune to SARS-CoV-2. I’m pretty sure there’s no enforcement mechanism that will keep a mask-wearing public from exhaling massive numbers of aerosol viruses. Post mask cops on streetcorners, checking mask types and adjusting them to fit correctly and well? Really? Most of the public doesn’t like masking and will do the minimum necessary to meet a mask mandate. I’m thinking a lot of them will wear their masks as loosely as possible, just for spite.

My conclusion is this:

Enforcing an effective mask mandate on the public is impossible.

I can already hear the crowd screaming at me: “The perfect is the enemy of the good!” Well, yes. In this case, the chain of contingencies leading to effectiveness is so long that anything less than perfect is just about no good at all.

“But if a mask stops even one virus…”

The fifty billion other viruses gleefully jetting away around the edges of your mask might want a word with you. Or maybe they’ll just laugh.

Note well: This is a controversial topic, and as with all such topics, I require heroic courtesy from all commenters. Screaming at me won’t convince me of anything; it just makes you look like a moron. I’d appreciate that if you take issue with something I’ve said, take issue with the point I actually made.

A year and some months ago, when the whole COVID-19 thing was just getting out of second gear, one of the doctors I see recommended that Carol and I take zinc and the OTC supplement quercetin every day. The explanation was simple: Quercetin is a zinc ionophore. Ionophores are chemicals able to transport certain ions through cell membranes through which those ions would not ordinarily pass. Zinc is known to attack viruses of all sorts, especially cold and flu viruses. Quercetin attaches to zinc ions and escorts them through cell membranes, into the cells where viruses replicate. Zinc stops virus replication cold.

This sounded familiar, and it was. About that time I had begun hearing of the work of Dr. Zev Zelenko, a New York physician who had begun treating early COVID-19 patients with a drug cocktail consisting of hydroxychloroquine (HCQ), Zinc, and an antibiotic. Dr. Zelenko has a wonderful metaphor describing the cocktail’s operation: Zinc is the bullet. HCQ is the gun. Sure, it’s a little more complex than that, but despite metric megatonnes of anti-HCQ bullshit in the media, the cocktail works.

I’ve seen quercetin described as a zinc ionophore in many places. HCQ is also a known zinc ionophore. It’s a prescription drug that must be taken under medical supervision to avoid certain side effects. However, people I know personally are taking it every day and have for years for autoiummune disorders. I’m not sure how you measure the effectiveness of one zinc ionophore vs. another, so it’s unclear how “strong” an ionophore has to be. Everything I’ve read suggests that quercetin is strong enough to kill viruses wholesale by escorting zinc into cells.

Quercetin has, at best, mild side effects. It’s found in many foods, including kale. Alas, I won’t eat kale, so I take it as an extract in a gelcap. Carol and I followed the physician’s advice, and we’ve been taking 800 mg of quercetin once daily in a formula that includes bromelain. We also take 50 mg zinc daily in the form of zinc gluconate. I’ve talked about this before here on Contra, though it may have been a whole year ago or more. I bring it up again because Carol and I have noticed something unrelated to COVID-19: Neither of us has gotten a cold since we began taking quercetin plus zinc.

And that, my friends, is worth something. My long-time readers have heard me bitch about catching colds and feeling miserable down the years. I get one or sometimes two bad colds a year, and a scattering of sniffles that last for a few days and vanish. We get flu shots, but we still got the flu really bad back at the end of 2017. So the experiment is this: Even though we’re fully vaccinated, we’re going to keep taking quercetin plus zinc, and see how long it is before either of us catches a cold or flu. (We’ll still get our flu shots. I’m a strong believer in vaccination.)

Now, a lot of the country is still hiding out, though here in Arizona mask mandates are mostly a thing of the past. So it’s possible that we ducked colds for the past fourteen months by simply not rubbing shoulders with people much. Those days are past. We shop at big stores like Safeway and Target and Costco even when they’re crowded and nobody has masks. In other words, we’re more or less back to normal life. And my experience of “normal life” prior to COVID was (at least) one cold a year.

Carol and I aren’t worried about COVID anymore. Is it possible that we don’t have to worry about catching colds either? I’m turning 69 in a week. I’ll recap in another year. There’s still no cure for the common cold, but if two OTC supplements can stop colds before they start, man, I call that a revolution–and one helluva birthday present!
