The point is this: it's not that the CDC is lying to us, or passing along bad data. It's that the data itself is incomplete because 1) we have far few tests for people who need them, so there's no way we are capturing all actual coronaviruses cases in these numbers, and 2) even if we had the tests we need, it's a lagging indicator and that "confirmed case" has likely infected numerous others by the time the test is confirmed.
So given all that, it doesn't make sense for the CDC to issue guidance on public gatherings or school closure recommendations based on that data, because the data itself is unreliable. That's why you see governors like Ohio's taking action based on what they know is coming rather than the unreliable data they have now.
Finally, I'm not talking about influenza in any way, shape, or form.
