New data from The Lancet on sepsis (a life-threatening dysregulated host immune response to infection leading to organ dysfunction) shows that in 2021 alone, 166 million sepsis cases and 21.4 million deaths were estimated globally. That's nearly 1/3 of all global deaths for the year. 🧵1/4

Considering the vast amount of evidence that Covid can cause serious long-term health problems, mitigating risk of infection is absolutely logical. This should be utterly uncontroversial. But alas, politics, tribalism, and a desire to conform trump logic for most people. Not me.

Canada is leading in safety with the new draft of the CSA standard on respirators. @dickzoutman.bsky.social, @juliamwright.bsky.social, @mark-ungrin.bsky.social, and I explain key updates that bring protections up to date with the evidence on respirator use against airborne disease transmission.

Here's a recording of my 10-minute presentation about addressing shared indoor air as an accessibility barrier in our learning environments. Feel free to share! youtu.be/HD0wVoN7Pr8

"Can we disconnect not caring about a pandemic from a rise in fascist politics, war crimes and genocide in Palestine, and a cost of living and housing crisis amid record private sector profits?" #covid #longcovid www.thespec.com/opinion/cont...

“Demo­cratic gov­ern­ments and equit­able pub­lic health must pro­tect every­day people more than they pro­tect private sec­tor profits and declin­ing pub­lic health stand­ards, or they risk pro­mot­ing fas­cist and eugen­i­cist logic.” www.thespec.com/opinion/cont...

TVO: "What does (losing elimination status) mean?" Dr. Bowdish: "It means we're on a list of countries that are torn apart by war & that don't have good public health -- & none of our G7 contemporaries are on that list. It shows that there are multiple systems that broke down to have this happen."

I try to be professional on this platform but there are times, like now, when it hits me hard on a visceral level that we are in the midst of a catastrophic global public health crisis and it seems, as a species, we've somehow decided that ignoring it is the best plan we've got.

It's Accessible Education Day at #UWaterloo! This afternoon, I'm looking forward to joining the panel "What are instructors doing to integrate accessibility in their courses?" My talk will focus on how shared indoor air quality is a fundamental barrier to accessibility and what we can do about it.

Clinics are the one place patients should be SAFE Colds, flus & coughs are the #1 reason why Canadians see a doctor …so where did masking in healthcare go? It’s political.

Last week, I was invited to be a panel respondent to a Keynote presentation by Dr. Maurita T. Harris at the Ethical Tech for a Global Future Symposium at #UWaterloo. Dr. Harris's talk was titled, "Human Factors, Ethics, and the Future of Responsible Innovation." 🧵1/4

Had a fantastic time talking to you, the other instructors and the students for this piece! Thanks for letting me cover this and thanks to Teaching Innovation Incubator for featuring it on the site!

Great piece on our course in @uwimprint.bsky.social @ #UWaterloo “Having the skill to see things from different lenses helps them see how different accessibility issues may manifest, whether that’s indoor air quality or something else. Solving those types of problems can help everyone.“

Just finished Risk Assessment training. The example for "hazard elimination"? "When the University closed during the COVID-19 pandemic and people were required to work from home." But... SARS-CoV-2 is still here, and we're back on campus. Did I just identify a hazard through the training module?

'Another consideration, when it comes to building immunity, is the growing body of research suggesting that for several months after a Covid infection, people become more vulnerable to other infections...' www.theguardian.com/world/2025/a...

“The use of in-home HEPA air purifiers resulted in clinically important reductions in SBP for people with elevated SBP in environments with relatively low PM2.5 concentrations.” www.sciencedirect.com/science/arti...

There's a more fulsome instruction guide on how to comment on the proposed standard at donoharmbc.ca/national-sta... Again, note that no other sector covered by the Z94.4 standard is attempting to undermine it in the way that IPAC managers are doing for healthcare. /6

Very well done analysis of risks of long COVID over time. “Overall, 4% of children and 10%–26% of adults developed long COVID” That is a lot of new cases of long COVID! COVID is bad for you. Don’t get COVID. Get vaccinated. Wear an N95 respirator. Clean the air we all breathe!

The culminating student symposium for The Wicked Problem of Accessibility course happened this afternoon @uwaterloo.ca, thanks to support from the Teaching Innovation Incubator! It was nice for the students to have this opportunity to share their projects with the #UWaterloo community. 😷

At next week’s symposium for the course “The Wicked Problem of Accessibility,” I’ve requested that masking be at least ‘strongly encouraged’, as I was told that a requirement is not possible. I'm providing CA-N95 masks at the door, alongside a new poster, instead of previous alternative designs.

"The current health and economic burden of long COVID may already exceed that of other chronic diseases and will continue to grow each year as more and more COVID-19 cases occur." academic.oup.com/jid/article/...

Next week is the final class for The Wicked Problem of Accessibility course I co-designed/taught this term. If you’re a #UWaterloo student, faculty, or staff member, feel free to stop by the Black and Gold room on July 24th and check out the students’ projects (and hang out with me, of course!)

Amsterdam researchers studied 106 children with long COVID and found 84% had impaired quality of life, with significantly higher rates of severe anxiety, depression, and sleep problems than children with other chronic conditions or the general population. www.nature.com/articles/s43...

Data from the Canadian Nosocomial Infection Surveillance Program indicate that ~30% of laboratory confirmed COVID hospitalizations are acquired via health care (vs. community or unknown) - perhaps that's where the figure is (inaccurately) coming from. health-infobase.canada.ca/cnisp/viral-...

The CSA Z94.4:2024 Selection, use and care of respirators draft standard has been posted for a 60-day public review period. If this standard is adopted, respirators will be required in health care settings by default. Your feedback can help.

Canadian COVID Forecast: Jun 28-Jul 11, 2025 SEVERE: none VERY HIGH: none HIGH: ON MODERATE: CAN, AB, BC, MB, NB, NL, North, NS, PEI, QC, SK About 1 in 120 people in Canada are CURRENTLY infected.

It’s Disability Pride Month. Many people can’t understand why we would be proud of our disabilities because ableism is everywhere. This month we celebrate disabled lives and push back on ableism & eugenics. We are not less than We are not expendable We will keep fighting

🛑Possible rabies exposure in Toronto. Contact with a bat. The person exposed hasn't been identified. Please share far and wide, it's vital the unidentified exposed individual receives post-exposure prophylaxis with rabies vaccine as soon as possible🛑 toronto.citynews.ca/2025/06/27/1...

So unless I missed something (and I'm being quick here, so please check), the NACI cost model assumes: - 7.5% annual COVID incidence - of those 0.5% (kids) to 2.5% (adults) get #longCOVID - of those, the average harm is only ~22.2 life days - #longCOVID ends after 1 year That has to be deliberate.

For all you Canadian parliamentary nerds - debate on the third reading of Bill C-5 has just begun. You can watch the live stream right here The first speech this morning is from the bill's sponsor, Senator Hassan Yussuff. #cdnpoli #SenCa #SenateofCanada

Apologies once again... We hoped to have a forecast out, if not Monday, then by mid-week, but unfortunately no massaging of the model would get it to a reliable iteration. I'm running it from scratch again, if all goes well, we will have the forecast out next Monday, June 30th. 🤞

In this week’s class on ‘The Wicked Problem of Accessibility’ at #UWaterloo we’re discussing IAQ! Before class, students are asked to watch this video. During the in-class portion tomorrow, we’ll be doing some calculations with CO2 data and how to select an air cleaner! youtu.be/KSGpPB3q6Oo?...

Students & their drivers deserve a safe & healthy ride to school, including clean air to breathe! School buses have poor air filtration & ventilation systems (air quality = bad) 😔 Wearing a respirator mask (N95, KN95, etc) & opening windows (when the outdoor air is safe!) can make a difference!
