I think this is a time for everyone, including myself, to recognize that what we know right now is a small part of what is taking place beneath the surface and the complexities and uncertainties are great. In such times, exercising the #precautionaryprinciple is critical. #onpoli
Emerging evidence suggests that Delta (aka B.1.617.2 variant) grows quickly, is at 27% share in Ontario (ST), may be dominant in weeks in Peel (Loh), has higher transmissibility, severity (new data) and the ability to escape a single vaccine dose (PHE-England).
We know that ICU and hospitalizations are still high while 2nd doses are still just starting to ramp up.

Six in ten Ontarians are living in health regions with high or substantial #covid19 school transmission risk. #onted #onpoli
Estimated school transmission risk levels for public health units, with population on the left (in thousands). This does not account for future vaccinations, higher transmission due to B.1.617 variant growth, low testing, future opening of businesses, or high local hotspot risks. Image
All I am asking for is a little #precautionaryprinciple after so many failed attempts to stem infections without school closures. All I'm asking is that we wait a few more weeks to actually see B.1.617 data and open cautiously where transmission risks are lowest. Just this once. Image

The false dichotomy of #lockdown vs #economy still not understood by governments

Delaying, avoiding lockdown costs money AND lives

And then there’s this thing that healthy people make a healthy economy. Sick people don’t.

That is your starting point. #Health

“The downside of being a bit more cautious is quite a lot smaller than the downside of getting it wrong.”…
The above warning comes as UK Covid cases rose by 4,184 on Friday – the highest increase since 1 April.

In NL cases reported today total 3914 in a population less than a third of the size of the UK.

And yet today PM Rutte announced almost everything opening in a week. Why?

John Oliver is manufacturing consent, and using coercion and shame to prevent an honest discussion of risk.

"there is at least a large unknown risk of a long-term hazard and ... that is not being discussed" —@BretWeinstein

full video:
"The number of ways in which this [mass vaccination campaign] is unsafe are many ... and we are not having a proper public discussion about it."

full video:

If you have been vaccinated, you have been vaccinated against the original version of the spike protein. But you can still get Covid, and you can still spread the virus. Especially variants.

"What are you likely to spread? Some variant for which the vaccine is not effective." ImageImageImage

In-depth individual interviews of 25 #women #workers at the Ambassador Bridge produced #breastcancer risk understandings & agency narratives.

Kathy said: “put us all together, and pretty soon you have just got lots of stories that all have the same ending.”

A thread

The research captures & explains layered & multifactorial influences on women’s narratives of #breastcancer risks & related agency and to see how #health and health knowledge are constructed in a #nested set of relationships.

Multiple information sources influenced #women’s #breastcancer risk and agency narratives.

Social, cultural & experiential information were all included.

#Workplace & #environmental exposures & socio-cultural aspects of work & environment were critical to the narratives.

🧵on the Toronto area SGTF (S-Gene Target Failure) study to detect B117 (UK variant). It looked at 11,485 positive tests over Dec 16 to Feb 3 and found 448 had SGTF* (3.9%). These charts show the growth.…
2. Note: Not every SGTF is B117 but almost all were confirmed with WGS (whole genomic sequencing). Rt for the SGTF was 1.17, non-SGTF were .82 meaning SGTF had an Rt 44% higher. This means that B117 is growing quickly (80% per week in recent weeks) and is projected to overtake
3. the old variants around Feb 20th in the Toronto area. Because the Rt (reproduction number) was only .82 without B117, we know the lockdown was working well in Toronto. It's only because the variant was a small share that infections and cases fell. If it had reached 100%,

Is it not astounding that @Ludvigsson announces that he will "refrain from continuing covid research after threats and hatred." I am actually dumbfounded. In #Sweden experts who have made mistake after mistake when criticized turn themselves into victims.…
It is a classic tool to deflect the reality of the damage these experts have done and to almost engage in revisionism in the hope that people will forget. During the Spring @AnnLinde went out in force shouting "discrimination" and "bullying" when #Sweden`s #Nordic neighbours
closed their borders to #Sweden. They closed them to several other countries too. But when #Sweden closed its borders to #Norway they responded with grace and understanding. A Norwegian newspaper nailed it by stating that one has to tread very carefully when criticizing anything

🧵Re Williams/Lecce school technical briefing today at 11am. I'd like to add a few thoughts on what a technical briefing should include (beside details on new precautions like rapid testing).
First, it should review not just selected evidence but all important evidence. #onted
2. It should explain the limits this slide and the modelling used. My understanding it is a simulation-based approach (ABM) which seems technically sound but it needs extra updated sensitivity scenarios run and it needs to extend to March.
3. While that is one useful input to decisions, it is only one. It also assumes continued case decline and high PH measure compliance. I point back to the major ww studies in the thread above. They statistically isolated school closures as very important in reducing R.

If the MOH's of Ontario are going to craft a letter on school openings and cite science I would at least expect them to comment on important work like this one instead of choosing selective evidence. #onted #onhealth @Sflecce…

Friends, as you know I've advocated #masks for long time. Certainly longer thn @CDCgov & people at my... place of employment.

Qualitatively, I believe they work. How much they protect is hard to quantify, however.

Today, saw something thought provoking in this vein.

Anti-masker in inbox wondered what we say in a year, when (in his words/imagination of future), consensus changes against masks.

If can't quantify good masks do, how we know benefit isn't marginal?

Valid question, but #PrecautionaryPrinciple says not to play no-mask roulette.
I was here when they said it was nothing.

~ when... it was no worse than flu.

~ when... it would "only" kill 100,000.

The latest is that "masks won't stop it". It *is* hard to quantify #mask effect — but, I'm sorry but I can't endorse that.

I'm just not that kind of asshole.

@jesse_kroll @linseymarr @dylanhmorris @DrNeeltje As with anything, more knowledge is better. When we study #airborne contagions or #AirPollution many disciplines are required. Clinical, forensic, environmental, social, & occupational epidemiology all must be informed by all science. 1/
@jesse_kroll @linseymarr @dylanhmorris @DrNeeltje The preference of 1 observational association vs a 2nd (but 'newer') observational association (both being classified 'low level' evidence until dozens of associations are collected) when confronted with a novel #CoronaVirus or any other contagion is not
#ScienceBased. 2/
@jesse_kroll @linseymarr @dylanhmorris @DrNeeltje We must be prepared to quickly apply or adjust existing (i.e., #influenza) public health non-pharmaceutical recommendations to those of a new threat when we know the risk of harm from these interventions is low. 3/

@evanderburg when you start to unpeel the public relations veneer from well-financed mainstream media campaign to impose #5G you will see there is PLENTY to worry about — & independent experts who actually know something are in sharp disagreement with #BigWireless

this .@CNN story claim:
@evanderburg @CNN

hereby challenge .@CNN to report #5Gfact: contrary to this blizzard of bland blanket corporate assurances, #BigWireless forced to admit to U.S. Senate committee hearing they aware of ***NO INDEPENDENT SCIENTIFIC STUDIES OVER #5G HAZARDS***

@evanderburg @CNN…

#BigTelecom, when actually on the griddle and presumably under oath, reluctantly admits industry is #FlyingBlind regarding human health effects.... they suspect but don’t want to know of the hazards.... #cancer #autism

Cellphone tower set on fire in Saint-Henri

yo .⁦@CBCMontreal⁩ .⁦@CBCAlerts

your story 👇 talks of “False narratives around #5G technology...” so by all means let’s deal with #5Gfacts & not mindlessly conflate with #C19



***no independent scientific studies of #5G safety have ever been conducted — #fact wireless industry reps themselves have admitted.***

this MUST be brought to public attention!!!

(it certainly has been kept quiet so far.... 🤔 yo #cdnmedia! )


2 /

any claims of #5G safety by #BigTelecom are cynical PR distraction ploy from core threats to human health (which #BigWireless, #lobbyists & servile ‘regulator’ .@GovCanHealth — both #PHAC & #HealthCanada — refuse to acknowledge)…

Brexit formally occurred on Jan 31. People had voted for it to have borders with integrity, even if there was an economic cost. The Con Govt immediately had an opportunity to put this into practice: it actually made sense to tightly regulate our borders, with #coronavirusUK. 1/
So what happened after Jan 31? The Cons moved immediately in the OPPOSITE direction. They refused adamantly to impose any border controls, and let flight after flight after flight in, carrying #coronavirus into the UK. Johnson gave this speech on Feb 3:…
The speech is astounding, the way it’s been ignored by the MSM v. revealing. In it, the PM insists the UK will remain open for business during the coming pandemic, no matter what the cost.
I repeat my key pt: this was the opposite of what one might expect from a Brexit Govt. 3/

Austria 🇦🇹 not alone in their attempt to gradually re-open after Easter. Denmark 🇩🇰 & Norway 🇳🇴 have similar plans:…. #coronavirus

Assessing the effect of each step will take at least two weeks. Isn’t the Austrian schedule a bit ambitious? I’m worried. /1
Interesting difference in strategy & priorities: Austria 🇦🇹 re-opens garden centres, Denmark 🇩🇰 re-opens primary schools first. Is there any epidemiological reason? Or are these strategies based purely on economic and/or social criteria? Any opinions out there? /2
Testing levels high in Austria 🇦🇹, but not so in Denmark 🇩🇰. Neither of these countries seem to have tested controlled samples to estimate asymptomatic cases, although such a study is under way in Austria. Is it wise to re-open before we have better estimates of true cases? /3 Image

Wow!! One of the most outstanding books I’ve ever read.

Sand Talk: How #IndigenousThinking can save the World

A great recommendation for these days!!

Thanks Tyson Yunkaporta. Your book is a gem to be discovered: #wisdom #values
A few years ago, I wrote a post about the #philosophy of Good Living or Living Well from Indigenous People…

I talked about #biomimicry, learning from Nature with humility, and then we could also learn from the wisdom of indigenous people
I've decided to start a month-long project where I'll tweet a “wise” tip about "Sand Talk" every day during April. 30/30

#WiseBoomerang #1 This will be the 1st one.
It's about #humility the antonymous of #hubris. #Communication #DialogicalEthics #Connectedness

@VRiffault @jljcolorado @WHO @DrMariaNeira Devil's advocate now... Unknown risk associated with lack of evidence when the volume of observations is high should provoke the precautionary principle if no harm is clear.
We dont know if an infectious dose is possible via micro droplets. But, they could be. What's the harm? 2/
@VRiffault @jljcolorado @WHO @DrMariaNeira There's a shortage of masks for medical workers. Full stop. That's the key message. We can & should make our own masks or use the reusuable pollution respirators with silocone seals that medical workers are not using. WHO recommends masks for asymptomatic influenza outbreaks.
@VRiffault @jljcolorado @WHO @DrMariaNeira 'non-pharmaceutical public health measures for mitigating the risk and impact of epidemic and pandemic influenza'.
Search "Asymptomatic". You will land on the relevant guidelines table.

Canada needs to step up #COVID19canada testing, locate clusters now, prevent Italy catastrophic outbreak.
Can’t wait for very ill patients to show up in hospitals, care homes, doctor’s offices.
Do these places have adequate #covid19 #InfectionControl
