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 👇 😢 globalnews.ca/news/10430626/…
@nb_covid_info @OhCasavant @RetractionWatch 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_covid_info @OhCasavant @RetractionWatch ...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_covid_info @OhCasavant @RetractionWatch ...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_covid_info @OhCasavant @RetractionWatch 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_covid_info @OhCasavant @RetractionWatch 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.

@carlzimmer @nytimes @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 @WHO report explicitly says that they do NOT take a position on that
@carlzimmer @nytimes 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…
@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: x.com/jljcolorado/st…

2/ The report was likely the result of intense pressure on @WHO during the pandemic: - They denied that #COVIDIsAirborne on March 2020 - They finally accepted it 2 years later nature.com/articles/d4158…
1/ @WHO has published a report on updated terminology for disease transmission I've seen some debate about it. My take: - Terminology itself is ok. Big progress - But no recommendations of how to protect! Report: who.int/publications/m… Press release: who.int/news/item/18-0…
It's like saying a boulder and a grain of fine sand are essentially the same thing. Yes, they are made of the same material. No one is going to refer to a boulder as waterborne, even in streams. And no, we do not treat them the same way for engineering and geoscience purposes.

Update: PHSA materials provide conflicting deadlines for this. Some suggest April 15 and others suggest April 16! Either way, questions are answered in the order received, so earlier is better! [email protected]

Just some questions about this study. How many times have these kids had COVID during the time mentioned in the study? Will results be the same if a kid has had Covid 2-4 times? I think that should be the next focus of these researchers.

@OhCasavant @Mark_Ungrin @Iamgoingtosleep @kprather88 @mdc_martinus @DRTomlinsonEP @EvonneTCurran @DavidElfstrom 😒 the fact that this asserts in several places that SARS was adequately controlled with droplet precautions, while in one place saying “medical OR N95 mask” is… frustrating. @DickZoutman

@AltenbergLee The head of the Canadian immunology society said even recently that since Omicron, infection immunity is the plan. x.com/OhCasavant/sta…
e. Measles & COVID hybrid immunity "So, this [Omicron] was a blessing in disguise (in my opinion) and helped with hybrid immunity and in reducing the impact of the pandemic." President of 🇨🇦 Society for Immunology, speaking in personal capacity via personal comm. Mar 2024

c. Measles & COVID hybrid immunity "With COVID19, we had no tangible choice but to rely on hybrid immunity..." 🧐😳 "...because mRNA vaccines have not been super-effective in “preventing infections". They were great at preventing/minimizing severe illness ..."
COVID’S EFFECT ON THE IMMUNE SYSTEM 🔥 This is an excellent series of graphics from @YaleSPH explaining what we do (and don’t) know about Covid’s effect on the immune system. Much of this is informed by the work of Dr. Akiko Iwasaki (@VirusesImmunity). 🧵 H/t @fitterhappierAJ
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 👇 😢 globalnews.ca/news/10430626/…
@nb_covid_info @OhCasavant @RetractionWatch 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_covid_info @OhCasavant @RetractionWatch ...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_covid_info @OhCasavant @RetractionWatch ...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_covid_info @OhCasavant @RetractionWatch It's not all on medicine either. As a society we all hear the stories, and look the other way. Every medical drama has its toxic character (often with some redeeming characteristic that pops up to reassure us). But we hear what nurses, and residents, and students go through,...
@nb_covid_info @OhCasavant @RetractionWatch 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_covid_info @OhCasavant @RetractionWatch 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.
@nb_covid_info @OhCasavant @RetractionWatch The real need is to deal with the sense of entitlement to be in charge, and not to be questioned. Similarly, you don't need a PhD to do good research. It helps, but there are people doing great things without one. The problem is when someone figures their MD comes with one.
@nb_covid_info @OhCasavant @RetractionWatch A lot of it is context. The ideal of EBM is great, and it can be very useful if practiced with humility and an awareness of its limitations. It's the intersection with toxic medical hierarchies that's the main culprit. Medicine tolerates and enables shitty people way too much.
@Mark_Ungrin @OhCasavant @RetractionWatch Being involved in EBM I see so many red flags now. I would really like to grow my skills in understanding and fighting the weaponization of EBM.
@OhCasavant @RetractionWatch Part of it is just how badly EBM has poisoned the well in medicine. It produces a perfect storm that combines a lack of understanding of science, engineering etc etc etc with the misperception of sitting above all of them. Ignorance plus confidence is a dangerous combination.
The WHO claims sneezing / coughing “droplets” of spit directly into someone’s nose/mouth is ALSO a proven method of transmission. They included references in their new document… unfortunately for them, @EvonneTCurran and @jmcrookston are checking each one.
