Wow, after a single week of on-campus instruction, student/staff COVID-19 infections went from 10 to 177, prompting UNC-Chapel Hill to move to remote learning: https://www.washingtonpost.com/local/education/unc-chapel-hill-coronavirus-cluster/2020/08/17/8ebce060-e0ab-11ea-8181-606e603bb1c4_story.html
”177 cases of the dangerous pathogen had been confirmed among students, out of hundreds tested."
"hundreds" tested
They probably have at least 1,770 cases out of the thousands not tested.
@lwriemen yes but the goal is not to find everyone infected, but to track the trend. You test 10 people and have 1 case so you have 10% ratio, you test 100 and has 10 cases so you still have 10% ratio, you test 1000 and have 177 - now you have 17% and raising trend.
@ruff How do we know a trend was being tracked? Why weren't all incoming students and staff tested?
When you swell a population shouldn't you expect a corresponding increase?
I was just commenting that studies have shown that COVID-19 cases may be being underreported by 10x due to asymptomatic cases and a lack of testing.

Sadly, I am not surprised. 😷
