1/ HOW TO HIDE YOUR DATA
In the highlighted section from Conly's presentation last month he references no transmission events in 5544 person-hours.
Source is "Conly J et al ARIC". Here's the section of that reference: (aricjournal.biomedcentral.com/articles/10.11…) H/T @jmcrookston @CPita3 There have been an estimated 5544 person hours of continuous
2/ Okay, so reference 26 is the Alberta Health Services Rapid Review. link: albertahealthservices.ca/assets/info/pp…
3/ And here is the 5544 person hours passage from the Alberta Rapid Review. What is the source? HIMSELF, personal communication.

This intellectual dishonesty has been used to support the denial of respiratory protection to front-line health care workers.
4/ It's been a year since that first data was collected. Surely he could have published it, perhaps with an extension of hours to expand the analysis? oopsie! There's been plenty of HCW infections since.
@CPita3 continues on in the thread:
5/ Oopsie, because that same April, SIX maternity staff were infected. That would have changed the narrative huh?

#Onted, who would be able to provide data on number of classrooms, students per classroom etc for Ontario so that I can do some capital cost and operational costs on air quality related upgrades? More than the 2015 facility condition list. edu.gov.on.ca/eng/parents/fc…
2/ I'm thinking of some per-classroom budget numbers balancing operable windows/fan, HRV, filtration, upper room UVGI, including energy costs/penalty, GHG emissions, maintenance.
3/ I can do analysis per classroom with an "average" class size or some distribution bins and then multiply through by total classrooms to arrive at a total $ figure.

WHO's pandemic guidance language for health care workers regarding proper PPE is belittling and paternalistic on matters of workplace safety.

This language is like when construction workers chastise peers for wearing PPE because they think it's a sign of weakness. In general, health workers ...
Reminder once again of the fallacy of the "AGP" (aerosol generating procedure). Regular activities produce FAR MORE bioaerosols than specific medical procedures.
Same document, just above. Back to harms from acne again. This whole paragraph has Conly's fingerprints all over it. The WHO COVID-19 IPC GDG co...

1/ I wear an N95 at locations outside of my home. I wear it to the grocery store, pharmacy and my doctor's office.

It's comfortable, doesn't hurt my ears, doesn't fog up my glasses, and easy to breathe through. I can wear it all day, anywhere. EXCEPT at the hospital! Photo of @DavidElfstrom wearing an N95 respirator and presen
2/ Many health care facilities require visitors to REMOVE their superior respiratory PPE and don a basic surgical ASTM Level 1 mask.

This practice must stop. Understanding the difference between surgical masks and N95
3/ Here's my friend Annamaria's experience this past Thursday when she went to @NGHSimcoe for her second vaccination, shared with her permission👇 When I got there, I stood in full view of the door and took

U of T is making all classrooms achieve 6 ACH with #ventilation and #filtration, the same as for health care patient exam rooms. They measured air flow.
THIS should be the target for all Ontario daycare, elementary, and secondary schools too.
utoronto.ca/news/u-t-asses…
Children will be the last to be vaccinated. Schools & daycares will benefit immensely from reduced cold, flu, seasonal allergies by upgrading to 6 ACH. The time to start was a year ago. The next best time is tomorrow.
Big shout out to @ShellyMBoulder and the UC Boulder team that led the way on this last summer.

This is bullshit policy @UHN. You won't permit a person to wear a clean N95 *respirator* (not mask) in your facility. You won't even allow someone to place your gappy surgical mask over top. Other health care facilities have no such problem. It's indefensible & unacceptable. /1 Image
Does a manufacturing facility say to a visitor "oh hey, take your safety shoes off and don our loafers".
Likewise, I've never been asked to remove my own provided hard hat in exchange for a bump cap or unprotected, as long as it meets sanitary requirements. /2
And you double down on it, even on April 22nd 2021. Can your Entrance Screening Working Group see their own logical fallacy?
If UHN wishes to maintain this policy, it should provide from a selection of pre-approved respirators. Charge a nominal fee if you must. /3 Image

LISTEN as highly influential Prof John Conly (upper left) of UCalgary, AHS CV19 sci advisory grp, Public Health Agency Canada, Chair WHO Infection Prevention & Control R&D Expert Grp. opposes N95 wearing citing acne harm vs @DFisman & @kprather88 precautionary principle. /1
"there's been decreased O2 concentrations in pregnant women" yeah, well here's the reference from one of his publications, dissected in fine form by @caruzycki /2
Here's an example of Prof Conly's influence by the dedicated @jmcrookston /3
