On schools and COVID. This one is a hot topic in our household as my partner is a developmental Pediatrician and I’m an ICU physician. It’s pretty clear that we are directly albeit oppositely effected by the school system and how it handles infections. Yes, we often disagree.
The pinion on which this argument seems to rotate is whether or not schools drive community transmission or they are just a function of it. There seems to be a lot of dancing around these definitions. We know when we shut schools down we see dropping community numbers.
The problem is, those measures come with a bunch of simultaneous interventions. Add lots of variables and it becomes increasingly more difficult to sort out which ones have the greatest effects. There is also heterogeneity amounts school resources and management.
Our schools and their staff have had to “step up” to do the work of public health in many cases. Clearly things they weren’t trained for. Resources are often scares and allocated differently. School populations are very different socioeconomically.
I am mentally removing the quotation marks around step up. Our school staff has gone above and beyond all expectations to keep schools safe and running, despite never being trained in public health. (Sorry 😬)
As an ICU doc, when schools close I relax, because I know community numbers will drop. No matter how well a school does at testing and isolating, the rate of asymptomatic infections in this population is a big problem. Point of care testing could have helped us there.
My wife sees the other side. Schools are a lifeline for her patients, and her patient’s families. Besides the educational and special needs aspects, they are an access point for a lot of social and support programs. They provide child care as well.
These repercussions are far less immediate but possibly more devastating in the long run. Parents know them. Teachers do too. Pediatricians are rending there hands about it. One thing is clear. This is yet another example of how the pandemic has shown social disparity.
Perhaps this is one of the most telling graphs I have seen in a long time about how to not get COVID.
As always, this thread is not going to give you simple solutions. Why schools are so contentious is because wealth disparity is so contentious, and our current thoughts about our social contract have become rather short sited.
“Sighted”. To fix schools, be need to fix taxation, support primary and secondary education, reform our approach to mental health, embrace primary prevention and addiction medicine. Schools are a microcosm of what is to come later.
But for now, it’s pretty clear that we are taking a gamble that our vaccine numbers will blunt the fourth wave. I think that is a long shot. If we really were looking at the science, we would wait until two weeks after 85% of our population had at least their first shot.
Because despite my optimism, I know that B1617.2 is out there. It’s more infectious then B117, and it will spread in schools, and out of them. On that, both my wife and I agree.

Thank you to everyone in education. You are my heros and my hope for the future.

Story time. I hope this isn’t too maudlin, but in the time of COVID, this seems to be the way we eulogize. Today I found out that my elementary guidance councillor died. It should have come as no surprise as he was also one of my patients.
I called his wife to express my condolences, but really it was to grieve over the phone with her. You see, this man was remarkable for so many reasons. Of course he was an amazing teacher, but he was also a force of nature.
I struggled in school. Our family moved around a lot because of my dad, & when we finally settled down, it was because of my dad. He got sick. My mom protected us, shielding us from the diagnosis. As a kid, normal is what you do every day. So I never clued in. Maybe intentionally

Last night before I intubated a lovely man with COVID, he insisted on calling his boss to explain why he wouldn’t be into work on Mon. He was so short of breath I had to finish the call for him. In the aftermath I realized how this job was a lifeline for him. It left me unnerved.
More and more this shows me how disparities drive despair. Without financial support essential workers and the marginalized don’t have a real chance at avoiding these risks. These are the people in our unit. Privilege is protective. I’ve known this, but damn, this hits me.
Without meaningful social change, most of intensive care medicine is just a band aid.

We relish working with the sickest patients & are privileged to walk the most agonizing paths with their families. It’s the impending sense of being overwhelmed at any moment that is grinding us down. It’s that we are here again, as though we have not learned that’s demoralizing.
I am constantly amazed by the heavy lifting our administrators do to adapt and keep things running. They must be feeling this weight as much as we do. The added pressure of being in a leadership role must be immense. I hope they have support too.
You won’t hear it from them. That job doesn’t allow a lot of disclosure, but they are fine people, doing their absolute best in really difficult situations. It’s a job I could never hack, and it is essential to keeping our hospitals running.

As we speak our @CMOH_Alberta and health minister are betting on vaccinations to temper hospital and ICU admissions despite our exponential case numbers. That is a high risk wager if they get it wrong. Based on current hospitalizations and past experiences we should lock down.
This is a similar situation to last wave. Though I hold optimism that vaccines will save lives, using lagging indicators just means we wait for young people to start overwhelming the system. Even though they tend to have better disease outcomes, this remains a percentage game.
This is predictable math. To make infection control an all or nothing game is naive and irresponsible. Lock down now. Continue aggressive vaccination. Open up at 80% vaccine uptake, regardless of how low case counts are. Better yet push for #CovidZero.

The Covid situation in Ontario is making people pretty jumpy, so let’s focus on some positives.
- GenX showed up like crazy for their vaccination
- Our elderly are vaccinated
- We have had a 2 week head start
- Our population is younger
- We have lower population density.
Now let’s focus on what we can do about it in the short term.
- don’t let your mask slip.
- support and advocate for racialized and essential workers
- enjoy spring while following the rules
- push for #covidzero
- help curb vaccine hesitancy (be nice about it)
- take the jab.
When your brain isn’t overloaded, in those quite moments, think about long term solutions.
- wage disparity
- marginalized populations
- health and social equity
- socialized healthcare and health prevention
- mental health and addictions stigma
- political polarization

Everyone keeps telling you that the side effects from AstraZeneca and Jansen vaccines are rare and you should get the vaccine. I totally 100% agree with this, but trust is only part of the equation. So here’s what I know about #VITT or vaccine induced thrombotic thrombocytopenia.
Let’s start with the name, because it tells us a bit about the problem. Thrombocytopenia means a low platelet count, which can happen for many reasons, and thrombotic refers to the generation of blood clots. When you understand that platelets are what start most clots ....
You really are a leaky meat bag. No offence. Platelets are constantly plugging tiny holes in blood vessels and maintaining vascular health. They are kind of like clotting grenades. Super effective at what they do, but you don’t want them going off in the wrong place.
