Enough Is Enough: Time to Finally Follow the Science on Masks
(written by a physician)

Recently I was "fact checked" by PolitiFact for a demo I did showing that masks don't stop the spread of aerosols (longer one here, shorter one here). The reporter asked for my comments and then said what his narrative required, without regard for any scientific data. The list of CDC and Medscape information in the video description escaped his attention. He also completely ignored the fact that Anthony Fauci has flip-flopped on masks more than a fresh-caught fish on deck.

Scientists have been very busy. When the Wuhan Flu came to America, we were told to constantly bathe our hands in sanitizer. Now we know that very few cases are spread by contact, so constant hand-washing isn't necessary. That leaves droplets and aerosols. Unfortunately, many studies use arbitrary size criteria to distinguish between them, giving us confusing answers. A better distinction is that droplets are too heavy to stay suspended in the air, so they follow a spitball's trajectory to the floor. Aerosols can stay suspended for hours, much like cigarette smoke.

Masks work really well against spitballs — oops, droplets. These larger particles hit and stick. They don't get through. So if you cough or sneeze, your mask, handkerchief, or elbow will do a great job of protecting your neighbor. But what about aerosols? You emit them every time you breathe, and if your neighbor sniffs after you break wind, you emitted an aerosol there, too. (Incidentally, COVID-19 is present in sewage in high concentrations.) We have enough data to show that these smaller, airborne particles are the real culprit in COVID-19 spread. How good are masks against aerosols?

We've all run into that irritating person who screams that "you're going to kill someone!" if you take your mask off. Supposedly, my mask will protect that person from me. But that's only half of the question. Will my mask protect me from you as well? The questions seem to depend on how well the mask filters. So scientists have gotten very busy looking at filtration. One study shows that single-layer cloth masks are essentially worthless, letting over 90% of viruses through. Others claim great efficacy. What's a mother to do?

Our first problem is to simply look at the aerosol mask studies. Virtually all of them use a mechanical gadget to measure how much gets through a mask. That leads to us learning that more layers work better. Duh! You knew that from your house's air-conditioning filter. Higher MERV and HEPA filters reduce the dust in your house. They also reduce viruses. An astute student of the obvious would have guessed that a better filter would reduce the number of viruses that get through a mask. But what I showed wasn't about filtration.

That "smoke" from a vape wasn't designed to tell you "how much?" of your breath went around your mask. That would be a "quantitative" demonstration. Instead, it was intended to show "what?" was happening with your breath. It's a "qualitative" demonstration. Where do the aerosols go? They go into the room to be mixed with the next breath and the next breath... Then they get recirculated and concentrated some more by the A/C system, unless you have a high MERV filter or UV sterilization.

Let's look at the lady who screamed about me killing the kid in the next checkout line.

... When that lady screamed that I was killing people by not wearing a mask, she was echoing the panic porn we've been fed for a year. There's no evidence that my mask is capable of protecting you. None. Will yours protect you? Not unless you are wearing a properly fitted (no leaks) N95 in a high-exposure environment as a health care worker. Either you breathe through masks that don't filter, or you breathe around masks that do. The air you breathe in has lots of aerosols, and some of those may be infectious. The bug doesn't care. It just floats on in through the big spaces in the lousy filters or around the edges of the good ones.

The real question that has to be asked isn't about mechanisms. We've known for years that mask-wearing has no effect on the transmission of airborne diseases in the general population. The study I just cited has one key difference from the mechanistic studies we've been talking about. It actually looked at whether mask-wearing reduced infections. That's called epidemiology and is about biology. The others were physical science. When the physical sciences demonstrate a difference but the biological sciences don't, whatever the physical scientists are measuring isn't relevant.

... A careful look at the charts shows that mask mandates did nothing except make money for mask-manufacturers and Emmy Awards for petty tyrants pimping masks and lockdowns. COVID deaths rose, and then fell, without any effect from masking. And these are the data we should be looking at.

It's worse than worthless to tell people that masks will filter out the virus when the data show that masks have no effect. It's the same evil that rises when we frighten people about how "deadly" the bug is as we learn how to treat it and it resolves into part of the background. Schools get closed, and children are irreparably harmed. People die from multiple other causes related to poverty from lockdowns.

It's time to lift the yoke of tyrants off our necks and take the diapers off our faces. (read more)
