In Jan there was a conference:
Breathing achievement into every classroom
This conference was designed to probe the link between Indoor Air Quality (IAQ) in educational buildings and the health, wellbeing, and educational outcomes of students.
UKHSA presented & IAQ experts.

There is so much to digest in this video.
I've been watching it on loop for 25 minutes.
Fortunately they've put all of the receipts in a thread.
Stunning.
@erbrooker gave one heck of a good presentation to a group of us academics at the @BristolUni this afternoon. Truly impressive and moving stuff.
Plus she brought her own CO2 monitor and homemade Corsi box.
Covid Cautious Survival Guide: The Terms You Forgot (Or Never Knew)
A field guide to navigating the pandemic reality everyone wants to ignore.
1. The Basics: FAFO Edition
- FAFO (Fuck Around and Find Out) – The inevitable consequence of pretending the pandemic is over. Ignoring precautions? Get reinfected. Act like it's the flu? Develop chronic illness.
- Covid Conscious / Cautious / Aware – Those who still acknowledge that SARS-CoV-2 is an airborne virus with long-term risks.
- Long Covid – The “post-viral” condition that is likely driven, at least in part, by a chronic infection that the body can’t clear that the ‘just a cold’ crowd pretends doesn’t exist, despite wrecking millions of lives.
- Immune Debt – A fake concept pushed by anti-mitigation folks to justify mass infection. The reality? Repeated infections degrade immunity over time.
- Immune Dysregulation – The real consequence of repeated Covid infections: a weakened immune system, increased susceptibility to other infections, and long-term health risks.
- FAFO Wave – When a new variant sweeps through, hitting those who ‘moved on’ the hardest.
2. Testing & Detection: Knowing When You’ve FA’d and Are About to FO
- RATs (Rapid Antigen Tests) – Tests that can miss early infections and asymptomatic spread but can still be useful with serial testing (test multiple days in a row).
- PCR (Polymerase Chain Reaction) – The gold standard for Covid testing that people forgot about when free testing disappeared.
- Viral Load – How much virus is in your system. Higher viral load = higher transmission risk.
3. Prevention & Protection: The Layered Defense Strategy
- PlusLife device (near PCR-equivalent testing for 97+% accuracy)
- #CleanAirClub – Movements dedicated to keeping indoor air safe, reducing Covid transmission, and preventing reinfections.
- CR Box (Corsi-Rosenthal Box) – A DIY air cleaner using MERV-13 filters and a box fan to remove airborne viruses. Cheap, effective, and the thing every classroom should have had in 2020.
- HEPA (High-Efficiency Particulate Air) – The real MVP of air purification, capable of removing airborne viruses like SARS-CoV-2.
- CADR (Clean Air Delivery Rate) – A measurement of how well an air purifier removes airborne particles. Higher CADR = better air cleaning (aim for 300 every 500 sqft)
- Fit-Tested N95 / Elastomeric / P100 – The real protection against airborne viruses. Not all masks are created equal. Cloth masks and loose surgical masks? Virtually useless.
4. Nasal & Oral Defenses: Extra Layers, Not Magic Shields
- Nasal Sprays (Enovid now NOWONDER, Nitric Oxide, Betadine, Saline, Iodine, Astronomer Sodium, etc.) – Can help reduce viral load but are NOT a replacement for masks or clean air.
- Oral Rinses (Listerine, Betadine, Xylitol, CPC, Hydrogen Peroxide) – Mouthwashes with antiviral properties that can reduce viral load in the mouth. Again, not a substitute for actual precautions.
- Blis K12 & Blis M18 Probiotics – Beneficial oral probiotics that may help with immune function and throat health, potentially reducing the severity of infections.
5. The Gaslighting Era: How We Got Here
- Endemic Theater – The myth that Covid is now "just like the flu" and we should "learn to live with it."
- Mass Infection Policy (MIP) – The unstated global strategy of pretending repeated infections don’t matter and sacrificing public health for corporate profits.
- Hygiene Theater – The outdated obsession with surface cleaning and hand sanitizing instead of addressing airborne transmission.
- Pandemic Amnesia – The willful forgetting of everything we learned in 2020-2021 about preventing infections.
- Biosecurity Denialism – The refusal to acknowledge the need for clean air, masking, and ongoing mitigation efforts.
Worked hard on this, and I hope it will be a useful resource for many.

🧵Brilliant to see children learning about CO2 monitoring, indoor air pollution and classroom air quality.
YouTube channel here for sharing clips directly with your schools and other important people 🙂

My partner is an anaesthetist. He took a CO2 monitor into work this week; the air quality inside surgical theatres is probably the best on the planet.
However, other areas of a hospital can have very poor air quality...

I regularly ask myself whether I'm right to be trying to avoid Covid infections.
Situations evolve and change, so it's worth staying up to date on information.
Have you signed up yet for our Annual Meeting on 25th March 2025? If you're keen to explore the boundaries of GLP1 & GIP with Prof John Wilding there's still time to register. View the full agenda here: https://t.co/XUgti71a4n
Cleaning the air with HEPA filters is such a simple, inexpensive & non-intrusive measure which can significantly reduce the spread of illness & exposure to indoor air pollution.
There should be one in EVERY classroom & hospital room.

If you are unwell with any winter virus or COVID-19, staying at home to recover is usually the best option.
Doing that also helps reduce transmission in the community. If you do need to go into an indoor setting, a well-fitting mask can help protect others around you.

This is such important messaging from @RoyLilley ⬇️
Even after all the evidence from the @covidinquiryuk, NOTHING has been done to ensure patients & healthcare workers are adequately protected from AIRBORNE pathogens in hospitals.
