“Getting sick frequently at school is not inevitable, and it isn’t because kids are just harbingers of viruses. It’s more because the buildings they inhabit do not have adequate ventilation and filtration systems to reduce illness transmission,” @mjnabuurs.bsky.social said. (Archive 🔗 in next post)

Thanks for this! It’s so great seeing more and more people being vocal and starting to organize around clean air in schools 🙌 🙏

There is a new study from Poland looking at children hospitalized for COVID during the 2023/2024 and 2024/2025 epidemiological years ( link.springer.com/article/10.1... ). 🧵1/

JFC. How long are we gonna do this?! "Exposure to higher aerosol concentrations - at close range or due to concentration build-up in crowded &/or poorly ventilated spaces - &/or longer duration exposures facilitate disease transmission." Water is wet. Ugh.

Dear Mr Carney, COVID-19 continues to mutate, circulate, infect, and disable (through long-covid). One of my Jr High patients got disabled by long-covid this year. Please implement a national clean indoor air strategy for all bldgs., airplanes, trains, buses, and more to prevent covid. Call me.

Also, clean the indoor air.

“Our findings redefine SARS-CoV-2 infection as a condition of long-lasting immune compromise.” Putting it all together: - covid is airborne - people are getting it repeatedly - it’s wrecking immune systems Please: mask, ventilate, filtrate, isolate, immunize. www.sciencedirect.com/science/arti...

Hitting up the bookstore

Please remember, every time you see a newspaper or magazine article denigrating people - people like myself - who choose to avoid infection with SARS-CoV-2, there will always be a tiny, quiet voice in the mind of the author whispering, 'what if they're right'? We are right.

1/ Season’s greetings from the team at Long Covid Support 🎄 Thank you for being part of our community in 2025. We know it’s been another challenging year for many, and we’re truly grateful for your continued support.

Many things will affect how well a student will do in school. Some you can control, others you can't One that affects every student (and teacher), and that we can control, is indoor air quality In this video I walk through how and offer some solutions t.co/sSU5efGhHr

Masks on. Infections down. Masks off. Infections up. Masks on. Infections down. Masks off. Infections… If I didn’t know any better, I would swear there was a pattern here. #maskingsaveslives #masksinhealthcare #commonsenseinhealthcare #HAIs #donoharm #stopthespread #normalizingsickness

Oh, wait. It gets better. 🤢🤢

We've been on the tarmac for over an hour, waiting for de-icing. So much coughing on this flight. 🤢 Air quality is horrendous. I have never seen such a high reading. Happy holidays!

Masks and eye protection required employees, professional staff, volunteers & students. Masks recommended for visitors. "A surge in cases of influenza and respiratory syncytial virus (RSV) has prompted Sarnia’s Bluewater Health to implement mandatory masking in all clinical areas starting Monday."

On the 6pm CBC news tonight, they led with a story on #influenza. The worst part? They featured an actress in a stage production who has been performing with the flu. No mitigations. No clean air. No masking. She was fine spreading flu to her coworkers and the audience. You do you, eh PH? FFS.

After the devastating loss of the 3 children in Ottawa, it was urgent to get info out re the additional ways avail to protect one’s loved ones from serious illness as we enter the holidays… and to remind young fams this amt of sickness ISN’T normal. #VaccinePlus ottawa.citynews.ca/2025/12/21/s...

Please sign petition. Clean air in school would keep our kids safer from viral infection, it’s also an absolute necessity in the age of forest fires smoke.

Canadian COVID Forecast: Dec 20, 2025 - Jan 2, 2026 SEVERE: none VERY HIGH: AB, MB, NB, North, QC, SK HIGH: CAN, BC, NL, NS, ON, PEI MODERATE: none About 1 in 55 people in Canada are CURRENTLY infected.

Signed & shared!

We have got to stop normalizing going in to work or school, or shopping, when sick. Far too many people out there hacking in public for anyone's good.

We are pleased to sign this petition ✔️ Anyone who advocates for clean air can do so, we don't need to be in 🇨🇦 #StrongerTogether

Air filters clean air so that young lungs don't have to. They cost less to run per child per year than the glue sticks you'll replace. This was noted in the letter we sent to the education ministers of the four nations earlier this week. We look forward to a response.

Thank you Ontario Society of Professional Engineers for speaking out on the need for clean air in schools and daycares! ospe.on.ca/community/os...

2/ Now add - ▶️ No clean air mitigations in most daycares & schools; ▶️ Winter + closed windows (poor ventilation); ▶️ No portable air cleaners (poor air filtration); ▶️ Holiday gatherings; ▶️ No mask mandates in most hospitals & healthcare settings; ▶️ & still no Far-UVC in public spaces indoors.

A real-world experiment in how schools spread viruses The main risk is not close contact, but prolonged exposure to contaminated air in enclosed spaces CO₂ >1000 ppm nearly doubles transmission ris It’s the air we share. We need ventilation and clean indoor air www.nature.com/articles/s41...

Sorry folks, I’m just so sick of people not putting their money or actions where their mouth is. If you’re looking for a way to start, two easy ways are mask in public & give to your local clean air group(s) that are trying to clean the air in schools. Here’s the Cville one: www.cleanaircville.org

Clean the air in schools FFS. "Prolonged exposure in shared, poorly ventilated spaces, which potentially includes several infectious sources, drives respiratory virus transmission more than close contact." www.nature.com/articles/s41...

This is a great tool for estimating the impacts of air cleaners in nat vent UK schools. Unlike most air cleaner selection tools which just size on clean air delivery rate CHEPA also considers the energy aspects depending on local climate.

Around 70% of COVID transmission also from schools. We urgently need clean air and are living with unnecessary infections.
