Thank you @jvipondmd for your impassioned presentation yesterday & the stimulating conversation at dinner. Your contribution to saving people & the planet by doing things right is inspiring.
👏👏👏
Thank you Hospital Engineers for sharing your expertise to prevent infections during hospital construction.
Thank you for all you do to keep patients safe in all of our healthcare facilities all of the time.
Thank you @EdRubinstein for teaching us that Infection Prevention & Sustainability are not in tension - in fact implementing things like reusables & sophisticated engineered systems are key to both.
👏👏👏
Thank you Dr. Titus Wong for your courage & insight to lead BC IPC in researching & implementing Engineered Infection Prevention solutions into Healthcare Facilties & mass transit.
Thank you, Dr Klompas, for encouraging us to challenge Dogma and to accept new paradigms as the evidence presents itself.
Thank you clearly laying out your personal journey to switch from "Droplet" to "Airborne" paradigm for SARS2 transmission.
👏👏👏
Thank you to @CanadamasQ, Swenco Medical, @PADMmedical@CAPPEM2 for donating Made in 🇨🇦 respirators & plant based medical masks to conference attendees.
Thank you as well for your extraordinary leadership throughout the pandemic - teaching about airborne transmission, adding air purifiers to patient rooms, & moving vulnerable LTC residents into better ventilated spaces.
Many thanks to @keithmcglone55 for doing an excellent job on the Scientific Committee & for his professional moderation of many sessions.
👏👏👏
Thank you to Kelli & Heather & Carly & all the organizers for a great conference.
A special thank you to Gerry, for her unwavering commitment to IPAC, to patients, to industry partners, to collaboration, to professionalism, to progress, & to always doing the right thing right.
It was great to catch up with so many ppl after 3 years.
It feels like such a privilege now, the things we took for granted before.
The renewed spirit was palpable & energizing.
I especially want to thank everyone who showed such keen interest & enthusiasm for Engineered Infection Prevention technologies & better masks & respirators Made in 🇨🇦.
You've certainly renewed my optimism for a better healthcare future & for that I can't thank you enough. ☺️
Safe trip home everyone!
Stay healthy.
'Look forward to seeing you next year. 😊

Risk mitigation of shared room ventilation and filtration on SARS-CoV-2 transmission: a multicenter test-negative study | Infection Control & Hospital Epidemiology | Cambridge Core - bit.ly/3Vf0RyX
⬆️ ventilation = ⬇️ Covid HAIs
Increasing from 1 to 6 ACH = 50% reduction
(~40% to 20% attack rate)
Increasing from 6 to 10 ACH = more reduction
(~20% to 10% attack rate)
"For each additional ACH, we measured an estimated 12% lower odds of infection, while presence of any RMV carried approximately 50% lower odds."
Canadian Standards Association (CSA) has called for universal respirator use in healthcare settings & when performing patient care outside of healthcare settings (eg – in the home) in the latest edition of CSA Z94.4, Selection, use and care of filtering respirators.
How you can help:
The draft CSA Z94.4 Standard is now out for Public Review until August 19, 2025.
Please weigh in with your positive, constructive comments at .
The draft Standard embodies the Precautionary Principle.
In the absence of risk analysis, N95s are required because healthcare spaces & activities involve daily HCW exposure to Risk Group 2 (RG 2) pathogens like Influenza and RG3 pathogens like SARS-CoV-2, often unknown.
hopefully we can all take the temperature down a few notches, after all, we're all trying to make the system better. 😊
Let's start with 20 ACH Laminar Air Flow (LAF) in ORs. Good idea from the 1960s & generally an improvement over lower airflows.
@alijzimmerman @naner81 @GhostOfSocrates @N0nyM00se @doctor_zeest Does it stop all airborne transmission?
Sadly, no.
Is it the best approach to stopping airborne transmission?
Sadly, no.
Does the medical community think it's the best approach to stop airborne transmission?
Sadly, yes. 😢
@alijzimmerman @naner81 @GhostOfSocrates @N0nyM00se @doctor_zeest First, several systematic reviews and comparative studies have shown that LAF is no more effective than Mixed Ventilation (MV).
Some comparative studies have shown MV to be superior
Because Hospital Acquired Infections are way too high & flash disinfecting air & surfaces immediately after occupancy, especially in hospital bathrooms, is a game changer for protecting patients (& HCWs) from exposure to pathogens
Because air and surfaces that are biologically clean don't transmit disease
