I wonder how many children the incompetence of our public health and infection control leaders has disabled in Canada? Insisting COVID isn't serious, doesn't spread in schools, spreading misinformation, ignorantly yet confidently denying the protection provided by respirators.

Ventilation/HEPA filtration is to prevent long range transmission of COVID, and extreme concentrations of infectious aerosol for the most part.

You definitely need a properly fitted respirator at conversation distance… and personally I wear one whenever I am in a building that

This is super interesting and useful inquiry!

Not only does CO2 provide a measure of rebreathed fraction & a proxy for fresh air intake, it’s also a measure of air pH which directly impacts viral decay.

Incredible research at intersection of environmental chem, #ClimateCrisis , #COVID19 #pandemic , #healthybuildings .

Poor ventilation not only ⬆️[infectious aerosols] but it can keep them infectious longer! And ... increase in ambient CO2 from climate change does so as well 😲

Chemicals also travel 'through the air'

And may be 'inhaled'

But they're not called 'Chemical Respiratory Particles / Vapours'

No one objects to calling them 'airborne' 🤔

PS - this story is also a brutally sad story of preventable harm 👇

NB citizen Covid Updates | nbcovidinfo.bsky.social Tracy Casavant Oh, BASc (Chml), MES Retraction Watch This sucks. There's so much more that needs our energies right now. But that's how the bad guys win.

This time around, we can't afford to let up when we're ahead. It's time to clean house, and end tolerance for bullying and toxicity in medicine. Do that, and the rest will come.

NB citizen Covid Updates | nbcovidinfo.bsky.social Tracy Casavant Oh, BASc (Chml), MES Retraction Watch ...in a very real sense with COVID we're paying the price for letting medical culture get the way it is. Looking back to Campbell, and Krever and beyond we had the information, but we took our eyes off the ball, and let the bad guys keep on keeping on.

NB citizen Covid Updates | nbcovidinfo.bsky.social Tracy Casavant Oh, BASc (Chml), MES Retraction Watch ...and there's this idea that 'doctors will be doctors', so we kind of abandon the people at the bottom of the heap, and let the bad ones run wild (because we know it'll be a fight, and we've got other things to worry about).

The 'Thin White Line' mentality doesn't help, but...

NB citizen Covid Updates | nbcovidinfo.bsky.social Tracy Casavant Oh, BASc (Chml), MES Retraction Watch So I don't think we can fix what's wrong with EBM inside EBM. It's going to take fixing a feudal medical culture that goes back to Semmelweis and before. That will take higher standards inside the profession (especially at the top), but probably also external oversight.

NB citizen Covid Updates | nbcovidinfo.bsky.social Tracy Casavant Oh, BASc (Chml), MES Retraction Watch It's that intersection between overconfidence and lack of understanding that's the problem.

TBH most of science is realizing you don't understand things as well as you thought you did. Look at the Great WHO Airborne Debacle - basically just overconfidence + ignorance.

If only.

For COVID-19 is dominantly airborne

Direct deposition not demonstrated for any disease. I think unimportant, only if someone coughs in your face

Surface was long exaggerated, due to not understanding air

Carl Zimmer The New York Times World Health Organization (WHO) 14/ Now, the more important decision is WHAT DO WE DO WITH THIS?

WHEN should we use protections for airborne inhalation, such as N95/FFP2 respirators, enhanced ventilation / filtration, CO2 meters etc?

The World Health Organization (WHO) report explicitly says that they do NOT take a position on that

Carl Zimmer The New York Times 12/ A pearl on that article: a medical expert complaining that the old terminology was nice because it was simple to apply EVEN IF IT WAS WRONG

[Even it people in hospitals got sick and died because of the wrong protections -- OMG!]

Not that uncommon...

nytimes.com/2024/04/18/hea…

World Health Organization (WHO) 5/ The old terminology had arisen in a period (~1920-2020) of extreme skepticism about the importance of airborne transmission.

We explained that in our peer-reviewed paper in the history, summarized in my pinned Twitter thread:
