.@crwells10, @abhiganit, @MeaganCFitz, @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?

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 https://t.co/XR2urcxML4

Had a great time talking to the grade 8 math classes @RockwoodPS about the application of mathematical modelling! Thank you @GbettsGina for the opportunity!

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 👇

[Jeffrey Townsend @JeffTownsend]

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.

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!

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.

[David Fisman @DFisman]

Relevant to us in Ontario.

[Dr. Meagan Fitzpatrick @MeaganCFitz]

Before we require anyone to walk into a school setting, we must lower our community incidence. The indicators for "moderate" risk from @CDCgov seem reasonable for considering A/B schedules among elementary kids:

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.

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!

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

@AmyGreerKalisz @MeaganCFitz @abhiganit @Alison_Galvani @cbauch1 @pratha_sah @DFisman You are so right. My wife (an @ugdsb teacher in this pic) basically said the last week was chaos. They wanted to show parents what their kids are heading into

What “social distancing” will look like in Ontario schools this year @abhiganit @Alison_Galvani @MeaganCFitz @cbauch1 @pratha_sah

[Gina @GbettsGina]

Here is a visual - 24 (3 seats empty here) in a Grade 8 classroom ready to welcome students. 2m distancing? No way. Not even 1m possible. Get the Boards to buy single desks? With what money? May gain more space but not a lot. THIS is a more likely reality for MANY classrooms.

[Jessie Woollacott @jesswoollacott]

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 @fordnation @Sflecce
