#COVID19Colorado
(not sure why it's not up yet)
Not a very complete answer.
Answer was that schools will need to rely on cohorting (limiting interactions, in essence, with groups of students)
Basically, the goal is to keep disruption limited to cohort first then school second.
What if three students in three cohorts are awaiting test results? Do all three cohorts quarantine?
And how big will cohort be?
I think CDPHE and CDE know that. And do want schools to open.
