I recognize a lot of names in the list of authors




They are wise, and know far more about #InfectiousDiseases and #epidemiology than I do

It is important to look at what this report does and does not say…

I don’t think there is anyone who would disagree with the message in these slides

Closing schools is a bad thing

Remote learning is disruptive and can lead to worse educational outcomes

As with everything in this #pandemic, poor and marginalized families far worst

In this slide the #ScienceTable argues that vaccination reduces the risks to children

Currently less than 50% of the 5-11 cohort is double vaccinated

Once again the risk is greatest for our #children with comorbidities or low socioeconomic status

They admit they don’t know…

1) Happy Holidays, everyone! Although I will be returning to work on Jan. 4, I wanted to underscore the seriousness of this, the 5th wave of the #COVID19 pandemic in Quebec. In this thread, I will focus on rising hospitalizations among the doubly-vaccinated.
2) First, I can’t emphasize enough the importance of getting vaccinated against #COVID19. The non-vaccinated are nearly 15 times more likely to be hospitalized with #COVID in Quebec than those who have received two shots. But it’s become clear even two shots may not be enough.
3) As the chart below shows, on Nov. 18, the province recorded 17 new #COVID19 hospitalizations. Of that number, a dozen were among the non-vaccinated or those who got a first dose. But five individuals were hospitalized despite two doses. Who were those five?

Interim public health considerations for the provision of additional #COVID19 vaccine doses.

Read full report here: Image
Providing all eligible individuals with the recommended dose regimen should remain the current
priority for #COVID19 vaccination programmes in the EU/EEA.

All vaccines authorised in the EU/EEA are highly protective against COVID19 related hospitalisation, severe disease & death. Image
Administering an additional vaccine dose to people who may experience a limited response to the primary #COVID19 vaccination, such as some categories
of immunocompromised individuals, should already be considered now. Image

Vaccination is key to protecting against serious #COVID19, including disease caused by #DeltaVariant.

With @EMA_News we urge 🇪🇺 citizens to get fully vaccinated as soon as possible!

Don't forget your 2nd dose.
Don't miss your 2nd dose.
With the increasing circulation of the #DeltaVariant in EU/EEA, #EMA & #ECDC strongly encourage those who are eligible for vaccination but have not yet been vaccinated to start and complete the recommended #COVID19 vaccination schedule soon.
Full vaccination with any of the approved vaccines = a high level of protection against severe disease and death.

The highest level of protection is achieved after enough time (7-14 days) after the last dose.…

Ontario Canada: "The world's longest #lockdown will come to an end next week" (Step 3, July 16/21).

No. It's not over.

New chief medical officer of health, Dr Kieran Moore makes clear #endemic state will emerge in fall w/ Ont. "doing all the due diligence to prepare." Image
Let's explore numbers behind "world's longest #lockdown", Ont., Canada. Gov't of Ontario website updated July 11, 2021.

"Active cases" in Ont. as of July 11 2021 under 20 yrs of age: 0

Deaths under 20 w/ #COVID19 - 3.

Estimated pop. of Ontario: approx. 14.73 million people. Image
Under 20 yrs:

Jan 15 2020 to July 11 2021:

Resolved cases: 68, 280

Active cases: 0

Deaths (WITH #covid19): 3

[Keeping in mind that Covid tests are inaccurate (false positives) & largely meaningless as testing positive can mean mild to no symptoms whatsoever.] Image

Just a reminder that this pandemic, far from being over, is gathering steam once again globally with cases going up across the world.
Yes, vaccines are starting to help. Half a billion doses have been given. But we are a LONG way from vaccinating ourselves out of this problem.
While vaccines are being rolled out, we need to keep using the tools from the last year: #physicaldistancing, test, trace, isolate, etc.
Fatigue and new variants are making the job harder, immunity from vaccines is slowly making it easier.
We have to hold on.
In the meantime deaths keep rising.
At the current pace we will reach 3 million deaths in early May. If the trend continues we will reach that sad milestone in April already.
Vaccinating those most at risk around the globe equitably would do a lot to keep that number lower.

1) Premier François Legault flip-flopped Friday, acknowledging Quebec is in the “beginning of a third wave” in the #pandemic only three days after insisting the opposite. Unlike previous waves, more contagious variants of the #coronavirus are to blame here and across Canada.
2) For much of the #pandemic, British Columbia has managed to keep transmission of the #coronavirus relatively low. But on Friday, B.C. authorities confirmed 215 cases of the P.1 variant, the same strain that is causing massive deaths in Brazil. Quebec so far has one P.1 case.
3) Meanwhile, Ontario on Friday declared it has 58 cases of P.1, up by four from the previous day. In total, Ontario has 1,612 confirmed variant infections, more than double the tally in Quebec. And like B.C., #COVID19 hospitalizations in Ontario are on the upswing. See below.

1) As Quebec on Monday posted 51 more presumptive cases involving the more contagious #COVID19 variants, new projections warn the province could be hit with a third wave in March and April that's much higher than the previous two.
2) Simon Fraser University researchers Elisha Are and Caroline Colijn wrote in a blog posting on Monday that most of Canada has been able to control #COVID19 recently, but they suggested that the B.1.1.7 variant (now spreading through Montreal) poses a much bigger problem.
3) Should B.1.1.7 become established, Quebec and five other provinces could be sideswiped by exponential growth in #COVID19 cases, with a doubling time of one to two weeks, compared to earlier doubling times of up to 40 days in Ontario. Please see the chart below for Quebec.

1) On the same day authorities announced 86 probable cases of the more contagious #COVID19 variants in Quebec, Premier François Legault announced he will reopen movie theatres, public pools and arenas on Feb. 26. In this thread, I will examine these contradictory developments.
2) The probable cases were confirmed mostly in Montreal and likely involve the B117 variant that originated in the U.K. The results followed the screening of 925 positive samples, but Health Minister Christian Dubé warned this does not mean the probability rate is 9.3%.
3) Dubé suggested it may be 2%, which appears to be the case in Laval. But given that the B117 variant is at least 50% more transmissible than the current so-called wild type, it may be only a matter of time before the B117 strain becomes dominant in the greater Montreal region.

1) Quebec reported five more cases of the super transmissible B117 variant Monday, raising the total to just 13. That compares with 303 in Ontario, 164 in Alberta and 29 in British Columbia. In this thread, I'll try to explain why Quebec is under-reporting the number of variants.
2) Clearly, Quebec authorities are behind Ontario, Alberta and less populous B.C. in sequencing the variants to determine lineage. But Quebec could add another category to its stats pending confirmation by sequencing: new figures on cases containing the N501Y mutation.
3) The three more contagious variants — B117 (which originated in Kent, England), B1351 (which appeared in South Africa) and P1 (which has swept through the state of Manaus in Brazil) — share the spike protein mutation, N501Y. Quick PRC tests can pick up cases with this mutation.

1) The more contagious and deadlier B117 variant has now been found in every province in Canada and is on the increase in Ontario. But Quebecers have been in the dark since Tuesday about the extent of the spread of this variant and others.
2) Montreal shopping malls are once again packed with customers, many not maintaining #PhysicalDistancing. Officially, Quebec has eight cases of the B117 variant that originated in the U.K. By comparison, Ontario, reported cumulative 303 cases Saturday, up by 28 since Feb. 11.
3) On Sunday, Health Minister Christian Dubé urged Quebecers to limit their social contacts, saying the threat of the variants remains preoccupying. Yet how can the government reinforce this message, especially to those in shopping malls, without regular updates on the variants?

Consequences of surging hospital admissions across the #midwest

1) Busy rural ER docs calling 6,7,8 hospitals to try to find a bed for a sick patient in need of tertiary care. And failing.

2) Repurposing existing beds to accommodate #COVID19 patients. 1/8
3) Rescheduling ever more urgent surgeries--heart surgery, cancer surgery, spine surgery--to some future date...a "less busy" date that is hard to see right now.

4) Staffing these new #COVID units, in some cases with non-ICU practitioners. 2/8
5) Competing for travel nurses to try to meet increased staffing needs. Many hospitals are short-staffed at baseline. Without an ICU team, an ICU bed is just a bed. 3/8

1/5 #COVID19 key concerns in 🇨🇦: With continued acceleration of infection rates in several areas + still rising hospitalizations & deaths, ↓ close contacts + keeping ↑ protections is everyone’s responsibility to save lives! #Everyday #COVIDhero…
2/5 The #COVID19 virus spreads from an infected person through respiratory droplets & aerosols created when an infected person coughs, sneezes, sings, shouts, or talks. Larger gatherings and indoor settings pose a higher risk.…
3/5 Droplets vary in size from large droplets that fall to the ground rapidly (within seconds or minutes) near the infected person, to smaller droplets, sometimes called aerosols, which linger in the air under some circumstances. #COVID19

Across Europe #covid19 cases are surging and the continent is shutting down again. Germany‘s second shutdown began yesterday, Austria‘s starts today, England is following on Thursday. How did we get here? What‘s the plan? Quick thread and my story here:…
First: What went wrong? Many ways to think about this. But to be clear: It was always going to be hard. I wrote about Europe‘s „dangerous“ path out of the lockdowns in April (…). Consensus was it would be trial and error. We erred, but did we really try?
In April, @gmleunghku explained 3 dials governments had to keep transmission in check:
test, trace, isolate -TTI
border restrictions
physical distancing

TTI worked reasonably well in some European countries. Border restrictions: meh. Backbone of strategy was #physicaldistancing

1) Across Canada, some efforts are underway to improve ventilation in schools to prevent children and teens from contracting #COVID19. In Quebec, however, little is being done. In this thread, I will call upon the provincial government to do something fast.
2) I first urged authorities in Quebec to upgrade ventilation in schools in early August. On Sept.26, with most schools already open for a month, Education Minister Jean-François Roberge announced $20 million for the maintenance of existing ventilation, not upgrades.
3) That investment works out to less than $7,000 per school. Quebec, with one-tenth of Germany’s population, is investing 2.37% of what Germany is spending to upgrade the ventilation of its public buildings, including schools and universities.

1) Nearly two weeks after Montreal public health officials disclosed a major #COVID19 outbreak at a seniors’ residence on Sherbrooke St. E., this cluster of cases still hasn’t appeared in the government’s daily updates. In this thread, I will note this is not the only omission.
2) Dr. Mylène Drouin, of the health department, had confirmed that the outbreak at Les Résidences Soleil Manoir Plaza infected 28, hospitalized six and killed one. However, only three cases are currently listed at the seniors’ facility and no deaths, according to Monday’s update.
3) Lest anyone dismiss this as an isolated incident, credit goes to Radio-Canada’s @ThomasGerbet for exposing information gaffes involving at least six other seniors’ residences and long-term care centres. Two outbreaks were absent from the updates.…

1) Quebec crossed a sombre milestone Thursday, declaring more than 6,000 deaths in the #pandemic, 15 more than all of Sweden, a nation with a population that is 1.7 million greater than the province’s. In this thread, I will highlight some other grim milestones.
2) Also Thursday, the province crossed the thousand-mark in the number of schools reporting either a student or teacher testing positive for the #coronavirus, according to In some schools, there are so many cases officials can’t keep track of all of them.
3) Again on Thursday, Montreal crossed the 4,000-case milestone of new #coronavirus infections in just the past two weeks. That tally in the second wave represents nearly 11% of all of the city’s cases since the World Health Organization declared #COVID19 a #pandemic on March 11.

1/5 #COVID19 key concerns in 🇨🇦: National daily case counts continue to ↑ steeply, with an avg. of more than 1,800 new cases being reported daily during the most recent 7 days. The number of cases hospitalized has also increased.…
2/5 An average of 585 individuals with #COVID19 were in Canadian hospitals on any given day and 14 deaths were reported daily over the past week.
3/5 New cases in Ontario and Quebec account for over 80% of the cases reported nationally over the past week. BUT, no matter the trajectory of your jurisdiction, we must all remain vigilant and committed to protect one another. #StrongerTogether

1) On the eve of Quebec’s announcement Monday that it will impose new restrictions in the #pandemic, a quarter of the province’s schools on Sunday night have declared at least one case of #COVID19 among students and staff. In this thread, I will revisit the topic of schools.
2) As of 9:44 p.m., 767 of the province's 3,000 schools have at least one infection, according to On the island of Montreal, 10 schools have reported at least five cases each. But authorities last week confirmed at least 30 school outbreaks in the city.
3) However, the extent of the #COVID contagion in schools is not fully known because authorities aren't systematically screening students, as they are in Germany. Even in classes where a student has tested positive, not every pupil is screened. It differs from school to school.

1) For three days in late June, Montreal reported no new cases of #COVID19 — a stunning turnaround in the #pandemic. But for the past three days this fall, the metropolis’s daily tally has averaged 362 cases. What went wrong? In this thread, I will offer possible explanations.
2) First, let me reiterate it’s highly unlikely, as Quebec’s public health officer suggested Sept. 26, the province has been hit harder by a second wave than elsewhere in Canada because of a more “invasive” and “lethal” #coronavirus strain. Other provinces have this strain, too.
3) Second, it was not inevitable that Quebec should be so hard hit during the second wave, especially given its tragic experience with the first one. British Columbia, after observing an increase in August, has managed to lower its incidence rate recently. See the chart below.

1) The number of Montreal school outbreaks has doubled to 30 in a week, the city’s top public health director revealed Tuesday. There are now as many #COVID19 clusters in schools as there are in the workplace. Yet authorities seem reluctant to want to do more to protect schools.
2) On Sept. 21, Dr. Mylène Drouin disclosed that there were 14 school outbreaks in the city and 28 in the workplace. By Tuesday, the two settings were tied at 30 each, followed by nine in health-care institutions, six in day cares and five following events in the community.
3) These figures would appear to demonstrate the #pandemic has been spreading more rapidly in schools than any other setting. Provincially, there are 1,043 active #COVID19 cases among students and school employees, according to the latest chart below by the Education Ministry. Image
