“316,000 tests and identified more than 8,600 COVID-19 cases.”
8,600 / 316,000 = 2.72% of those tested are positive. We can assume that typically only people who have known exposures or symptoms have been tested. This thing does not appear to be as contagious as we have been led to believe.
Exponential growth, early days yet.
Your point is even stronger considering a lot of those are false positives. I notice nobody gives the false positive rate, which is probably 1% or more.
