An expansive musing thread on mask non-use, which I am now calling "mask akinesia".

Every class I teach, I walk in with my mask and my Aranet4 CO2 detector, to measure air quality. I'm lucky: the rooms I teach in are always below 800ppm and often below 700ppm.

1/20
I make a show of measuring air quality with my mask on.

I often remind them that the air is excellent but that doesn't lower the risk from people sitting immediately around them.

~4% of my students wear masks. ~30% have missed class because of COVID, some cough in class.

2/20
One day, CO2 was 1800ppm, too high! Two of 3 air exchangers weren't operating. I told the class that the air wasn't safe, and to put on a mask if they had one.

They heard me and looked concerned. And nobody moved.

Alright, I thought, none of them have a mask.

No masks.

3/20
I messaged them all the day before the NEXT class to say that I had reported the problem but it may not be fixed yet, and to consider bringing a mask.

Sure enough, it hadn't been fixed.

And sure enough when I announced the air was still risky ... nobody moved.

No masks.

4/20
Many of them know that I stay informed about COVID and that I have a genuine interest in safety.

And I'm testing the air right in front of them. And telling them that they need a mask to be safe in this room.

And no masks.

5/20
I don't get the sense that they are dismissive. I see concerned faces, not eye rolling.

I point to the growing number of empty seats, and tell them about the number of students I have heard from who need extensions because they are too ill to work.

And no masks.

6/20
These are bright, ambitious people on the whole. They're graduate students. They are investing a lot of money in their education. They're being told directly by me, in person, in detail what the present risk is.

And no masks.

7/20
This is "mask akinesia" - the inability to initiate the activity of having a mask or donning it.

What is the cause of this dangerous condition?

I think the answer is easy. I also think that means we need to come at COVID safety entirely differently.

8/20
Mask akinesia is about being normal. Normal.

Normal is defined as what the herd does. It's not about what is right or good or safe or natural or just. It's ONLY about what everybody does.

Masking was never normal, even though everyone did do it for some time.

9/20
Psychologists frame "social conformity" - which comes in a few different flavours - to talk about our tendency to conform with the herd as a way of belonging to it. (Maybe it's a sociobiological drive?)

Sociologists see "organizational culture" in much the same way.

10/20
The implication here is that going against normal isn't typically sustainable. Changing what is normal absolutely happens, but over very long time frames.

Drunk driving and smoking were very normal. It took generations to change that.

11/20
What concerns me about normal is that in choosing to believe flu is mild (which is quite normal) we also maintain normality in dying of an avoidable infectious disease.

When we started pretending COVID is like flu, we make it all even MORE normal.

That's why no masks.

12/20
My class not masking (described earlier) demonstrated to me just how determined we are to be normal, & not risk losing normal like we did 2020-2021.

Mask akinesia is normal.

Changing normal can take decades; fighting against normal is unsustainable and also untenable.

13/20
Instead of going AGAINST normal, I think the sustainable path forward is to try to ADD to it.

I want to make indoor air quality monitoring normal. By which I mean not only measured and displayed for everyone to see, but with the public understanding what it means.

14/20
We started doing this years ago with a UV Index in summer weather reports. That's normal and introducing it didn't require fighting against normal.

The UV index enables people to consider this invisible, dangerous reality, when planning their activities.

15/20
Now, a convoy type might point out that because UV light kills COVID, bring on the sunburn. That would be missing the point.

My point is that we have a social model for making an invisible danger visible, increasing awareness and consequent safety behaviours.

16/20
And here is the best part, IMO:

We don't have to fight against <COVID-is-over> normal, because indoor air quality has a whole bunch of beneficial effects, and not a lot of detractors.

(Remember wood smoke from summer forest fires? That's another normal we can't change.)

17/20
If air quality is excellent, there's less disease circulating; both mean less need to mask.

The large rooms I teach in have great air so I can lecture "au naturel" (b/c nobody is near me - but mask is always on before, after, & during break).

That's a safe normal.

18/20
Great air quality has no detractors except for governments and employers, of course. They'd have to pay.

What's normal for them is to only pay for what they have to, but also to yield to sufficient pressure.

I'm looking for opportunities to motivate that pressure.

19/20
One last thought. Very few people I know have HEPA filters or CO2 monitors. Many can't afford it, but I'm talking about people who easily can.

If you can afford this vital equipment, I'd like to ask you to help enact a new, healthy normal. We have to start somewhere.

Lost: one public health system.

@TOPublicHealth data show that only 4% of primary school kids have the new XBB COVID vaccine, the variant currently ripping through schools.

Adults aren't much better, tbh. Even the 70+ group is only 28%.

Hmmm ...

It seems pretty hard to have vaccine conversations these days. I do anyway.

There is a whole ton of misunderstanding out there. Even among people I know who are smart and usually aware.

Public misunderstanding happens when public health stops communicating.

2/8
I believe that it is collective societal trauma that is making it hard for people to acknowledge COVID now, let alone to take simple steps, like improving air quality, to be healthier.

But that's a piss-poor excuse for public health not even trying.

What is going to happen with COVID this fall? Well, here's a worried thread ...

First, I do not believe we are seeing anything seasonal about COVID at all. Wastewater signals were elevated but not climbing all summer. Hot weather and being outdoors helped a bit, I'm sure.

1/15
But it's important to understand why respiratory viruses are seasonal in the first place, and why COVID is different.

Flu, colds (etc) have a basic reproduction number ("R0") only slightly higher than 1. Remember that R0>1 means sustained transmission; R0<1 fizzles out.

2/15
R close to 1 means these viruses need ideal conditions - lots of unmasked people sharing unfiltered, recirculated air - in order to propagate. We do much more of that in the winter than the summer.

But COVID has R0>12 (maybe even higher). It doesn't need ideal conditions.

Having recently finished the largest single deliverable of my life, I'm heading out tomorrow on my first actual vacation in 4+ years: scuba in the Caribbean!

Yes, I'm psyched. (Also indescribably exhausted.)

How will I handle COVID safety?

1/7
Well ... literally 100% of COVID cases known personally to me since May have been acquired through travel.

This is because travel is high risk and almost nobody is taking even basic precautions ...

2/7
I previously tweeted about the very high risk of queuing up to board planes in airless jet bridges, and ventilation systems turned off before takeoff and after landing.

Hotel air is another major risk.

But travel also involves "population mixing" ...

"Sherpabody" is my new favorite word, thanks to a research team at the University of Helsinki. They have designed a very handy anti-viral molecule that could become a highly potent, variant-proof, COVID-cancelling nasal spray, And it could be taken before OR after exposure.

1/5
A sherpabody is a lot like an antibody - a particle that attaches to virus, gumming it up so it can't infect.

This sherpabody attaches to a distal part of the spike where very little mutation happens, and causes the spike to change its shape, causing dysfunction.

2/5
You can completely wreck a protein by deforming its shape. But this sherpabody is more elegant: it causes the spike to permanently alter its position from "ready to infect" to "already shot wad".

Consequently, the virus can still attach to your cells, but it can't infect.

A short update thread on my COVID-19 infection. I tested NEGATIVE yesterday evening and again this morning (day 14). Yay!

What does this really mean, though? To misapply Churchill, this could be the beginning of the end, or the end of the beginning...

1/8
My respiratory phase is clearly winding down, with no detectable viral load in my nose or throat. That doesn't mean ZERO virus, it means a low & diminishing viral load.

We don't know average days to get to ZERO, nor whether any lingering virions are actually active.

2/8
That is because neither rapid nor PCR tests differentiate live vs. dead virus.

Also, rapid tests aren't sensitive enough to differentiate between low and no viral load.

PCR tests are TOO sensitive and can pick up dead fragments for weeks after an infection is truly gone.

A follow-up thread to the one I posted two days ago about my COVID infection, specifically about vaccination and nasal anti-viral spray.

(Day 11 today: I have some nasal congestion but otherwise I continue to feel good. My positive test was faint for the first time.)

1/8
A few were disappointed I didn't mention vaccination. (And some expressed glee that vaccines don't work.)

I am maximally vaxxed/boosted. We know the vaccine doesn't prevent infection, but does protect against serious illness. I would seem to fit that description perfectly.

2/8
Next: my use of Enovid nasal spray. Very recently I had posted two threads on this topic, looking at the evidence. I'm not a clinician, I don't tell people what drugs to take, and my conclusion was that more research is needed. But I chose to use it.
