AIRE v3.6 is out.

Added:
• Scenario presets
• Turnover modeling
• Time-to-threshold risk
• Clearer CO2 assumptions

Small version bump. Meaningful improvements.

2/2

Covid-info.de uses a formal exponential build-up/decay formula, whereas AIRE uses shared-air proxies, which are computationally simpler and incorporate CO₂ optionality.

1/2

As of right now, AIRE adds a turnover model that covid-info.de does not.

AIRE separates presence from dose, while covid-info.de embeds prevalence into the dose model structure.

Y'all! @drseanmullen.bsky.social has created a tool that shows how doing COVID risky stuff translates into how many cigarettes you might as well be smoking by taking those risks.
I quit smoking for a reason. Because I'm not stupid. And it's the same reason I don't intend to ever get COVID again. 🚭😷

“Hybrid” immunity (infection + vaccination) is worse than vaccination alone.

So it just doesn’t make sense anymore to keep it in there…

Every infection causes damage. I’ve removed the protection of vaccination because asymptomatic and “mild infections” still show damage at 3, 6 and 9+ months in kids and adults.

They save you from immediate death and hospitalization.

That’s about it. Very limited data to suggest protection from LC

No vaccine is perfect. Measles is spreading again. The reason?
People stopped getting vaccinated.
Even vaccinated will get sick due to waning of the effects of their immunization.
Yes, the SARS2 vaccines aren’t as good.
But it doesn’t help that uptake in adults & children has been <35% for 2+ years

That is nice. Two weekends ago, my wife, daughter and I were at a tennis tournament.

Same deal. A couple said, “You’re so smart to be wearing a mask right now. We always mask now on planes.” 😂 I kept my mouth shut and my wife was like, “Oh yeah, we mask a lot to keep us all healthy.” 🙄

Perfect 👌

Yes, and this is one of the studies. So many limitations & overgeneralizations from this study.

I still don’t eat indoors in public or go anywhere without masking. I built this to show it’s not worth the risk. For example, when community prevalence is high children are losing the statistically equivalent life minutes of a half pack of cigarettes per day. Long Covid risk isn’t even factored in.

Dr Hoerger doesn’t have an API, but I’m hoping he’ll either let me build him one or just take my calculator and I’ll help him embed it on his site. For now, you can manually use the figures for your state using his estimates or the presets.

1 pack = 400 statistical life-minutes.

It is a metaphor, not a biological equivalence.

Turn it off if you prefer minutes only.

AIRE is not a medical device. It is a transparent risk budgeting tool.

I built AIRE, a free browser tool that estimates airborne COVID risk indoors using the PMC framework.

It also offers an optional “cigarette pack equivalent.”

Why?
Because 3% per event is abstract.

Cumulative harm is easier to grasp on a familiar scale. 🧵

Thanks 🙏 Yes, indeed.

😂 I never hid that about myself. I marched in the Rose Bowl Parade in my HS band of over 400 (color guard included).

I will be there in April, in Chicago, presenting a few things, unrelated Covid (but applicable). I have a verbal presentation. My doctoral student has two posters.

I’m presenting on a measure of perceived mental fatigue.

“The Society of Behavioral Medicine unites researchers, clinicians, and policymakers to advance healthcare through behavioral science—enhancing patient care, shaping policies, and improving health outcomes.”

Going to do what exactly?

Now Nature is reporting how Covid-19 infection increases risk of long term kidney damage so kidney assessment during routine physicals is really impt

No

Required to attend a 2026 meeting of health behavior change scientists:

“Exposure or infection may result in… permanent disability and/or death.”

“I hereby release, covenant not to sue… arising from or relating to illness, disability, or death…”

Risk acknowledged. Liability transferred.

You can hate AI, despise the environmental impact & erosion of education, the artistic theft, etc.

But if you want to put out a headline that video/AI is causing brain damage, you might want to control for Covid.

How many research labs are even using airborne mitigations?
Got 2 purifiers in mine!

In my class, all of them do their own work.
But far too many instructors have acquiesced to AI content.
That said, AI doesn’t cause brain damage. The 2 studies reported to do this were ABSOLUTELY AWFUL, misleading, & didn’t account for recent infection.
Just yesterday:

It’s pretty simple.
There’s a timeline.
There are also mechanistic studies.

Social media doesn’t destroy T cells.
Social media doesn’t destroy neurons.
Social media doesn’t destroy the entire vasculature.

SARS-CoV-2 does.

I’ve said for years that repeated SARS-CoV-2 infections would have devastating cognitive consequences.

Teaching ~400 students annually, I’m watching executive function erode in real time.

We can debate tone.
We can’t debate trends.

You created a burner account to observe the feed and concluded “wow, lots of COVID posts.”

Yes. Because there’s an enormous body of research on cumulative harm from repeat infection.

The algorithm amplifies. The science predates it.

It’s not “anti-vaccine.” It’s COVID competence.

Before labeling people, try engaging the evidence. There are 500,000+ studies on the immediate & long-term damage from SARS-CoV-2 infections.

Cumulative.
Permanent.
Persistent.

Read a few. Then we can talk about what’s “doomer” — and what’s reality.

That’s important feedback. Identity should reflect how someone integrates movement within their own limits, not whether their body allows conventional expressions of it. I’ll be thinking carefully about how to refine that distinction. 2/2

Thank you for this. I really appreciate you raising it. The mirror is intended to measure identity structure, not physical capacity. But you’re right that for people living w/ significant mobility constraints, some movement items can blur the line between intention, effort, visibility & function 1/2
