1) Montreal based #Covid19 thread: National Geographic hosts an airborne Covid-19 infection risk calculator designed by a research team led by by Jose-Luis Jimenez at the University of Colorado Boulder at https://www.nationalgeographic.com/science/2020/08/how-to-measure-risk-airborne-coronavirus-your-office-classroom-bus-ride-cvd/?fbclid=IwAR3g3wFpuKItKz2bvWMjDmgQ55RhRN2g1FEZGkpXvcDpySp6mrp_5CJeWj0#close

2) Messing around with defensible assumptions that follow and found that between EACH student and teacher in a Montreal classroom is between 5% and 48% likely to have infectious exposure to Covid-19 in 20 days of school (4 weeks of classes)

3) This assumes:1-no masks as they aren't required in class; 2-that the ratio of 14 day new cases in Montreal to 14 day new Quebec cases is the same as the ratio of active cases (for calculator purposes);

4) Third assumption that, since 3 feet of distance is admittedly impossible, students have 2 feet of distance from others; but also 5) that students spend only 3 hours (calculator maximum) in class for those days. It would be higher for the full 6.

6) @jfrobergeQc please read this thread from the start and reconsider! Knowing this and moving forward is tantamount to the criminal negligence the inevitable lawsuits will otherwise invoke as they plead their case! /endthread

@ArrudaHoracio Please read this thread and revise your gamble with so many lives
