This could, *could* explain why the number of new cases at the worldometers site have been fairly steady over the past few weeks but the number of new deaths is in steady decline.

It could also potentially have something to do with the weather somehow.
Personally I think - without any reasonable basis other than optimism - that the virus is more contagious and less deadly than is generally thought. If so, then reopening would tend to result *not* in a second wave.
I am fascinated to see what happens in the next few weeks as the US continues to open up. I don't know about generally but my state is in phase 3 of a reopening plan and so far the new deaths have been increasing but at a slow pace which is well below hospital capacities. For those who think that a second wave will happen, I wonder why we have not seen it in my state even though we've been reopening for a month now and I was under the impression that the virus has an incubation stage that is much less than 1 month.
I agree that there's a lot we still don't know about this thing. I think we collectively want certainty so in some cases are taking our reasonable first estimates about it's many facets as accurate when they may not (probably won't?) turn out to be.
