THREAD: Excellent modeling study of college reopening shows weekly #Covid testing led to 37% of student body contracting Covid; with ~biweekly testing, 7.5%. Yikes. 4 major concerns. http://ja.ma/2D9bI93  @ADPaltiel @RWalensky

First, the study assumed a test turnaround time of 8 hours. Yet some locations in the US have 2 week backlogs. If colleges can’t access <24-48 hour turnaround, how will their testing strategies hold up? Should they open? (2/5)

Second, the authors acknowledge they focus solely on #Covid spread in students. To truly inform decision-making, would love to see a model that includes faculty, staff, and surrounding communities. Most essential workers aren't healthy 20-year olds... (3/5)

Third, at what point does a college send students home? If a school is hurtling towards a 20% #Covid_19 infection rate by semester’s end, when do the shift gears? Need clear, a priori, rules for changing strategies, and calling it quits. (4/5)

Notably, the authors generously make their #Covid_19 testing model publicly available: https://bit.ly/3fmXUoC  But this is not an academic exercise: as we head into the fall, the model assumptions will soon become actual experiences/data. (5/6)

Finally, as colleges and local communities struggle with #Covid_19 this fall, lets commit to timely sharing of not only testing/mitigation strategies *but sharing actual #Covid_19 testing results* following @ehbvassar's example of transparency.
