What “social distancing” will look like in Ontario schools this year Abhishek Pandey Dr. Alison Galvani Dr. Meagan Fitzpatrick Chris Bauch Pratha Sah, PhD

#COVID19 hospitalizations, unlike deaths, are broadly distributed across middle-aged and older adults in Ontario. Preliminary work from irena papst, phd 👩‍💻📉🦠 and #MacTheobio medrxiv.org/cgi/content/sh… @MLiwz1 @DChampredon @bolkerb David Earn

The 👏 social 👏 science 👏 component 👏 is 👏 being 👏 overlooked 👏

This is a real classroom with 25 people sitting at desks, they are less than a metre apart and 8 people are missing - 33 students are scheduled to be in this room! This is NOT social distancing! This is not putting our students first!!!!!! #UnsafeSeptemberON Doug Ford Stephen Lecce

"“Climate change is the big driver,”...The best way forward, is to “de-harden” surfaces, support wetland coastline buffers and fund natural-based solutions.

Kids started their remote learning today. Bought them their own laptops, they have desk space, and I’m supervising. I somehow ended up with a lab!

France and Spain have been a few weeks ahead of Ontario for some time now. If you don't like the way this graph looks, now is the time to make the hard decisions. Christine Elliott Doug Ford Andrea Horwath Marit Stiles

Before we require anyone to walk into a school setting, we must lower our community incidence. The indicators for "moderate" risk from CDC seem reasonable for considering A/B schedules among elementary kids: cdc.gov/coronavirus/20… 3/4

Relevant to us in Ontario.

Important thread. We have a lot of movement in the province this weekend; the people doing the moving are the highest-prevalence demographic. It may translate into more covid activity around the province.

The 11th Ebola virus epidemic in Democratic Republic of Congo is now officially over. "Vaccination efforts began just four days after the outbreak was declared. Around 90% of the vaccinators were from local communities." Amazing! bit.ly/35LxtHP

Avoiding any contact with other people for a week or more before taking a test is a powerful tool. Not only does it decrease exposure, but it also gives the virus more opportunity to reach detectable levels in infected people. nytimes.com/2020/11/21/ups…

We’ve been in an “absence of evidence” state because schools closed early in the spring. The evidence is becoming clearer and clearer that children and schools matter *a lot* for #COVID19 transmission. Thread 👇

Had a great time talking to the grade 8 math classes Rockwood Centennial Public School about the application of mathematical modelling! Thank you Gina for the opportunity!

I'm giving a public lecture for the US National Museum of Mathematics on COVID-19, mathematical models and game theory, this wednesday (one talk at 4 PM EST, same one again at 7 PM EST). Should be accessible to ages 12+. Register at momath.org/math-encounter…

.Chad R Wells, Abhishek Pandey, Dr. Meagan Fitzpatrick, Dr. Alison Galvani, collaborators, and I have addressed a longstanding gap in the science of public health: when there is already community transmission at a destination, how much travel quarantine can be justified? authors.elsevier.com/sd/article/S26…
