And of course the second most important thing to know I think is whether or not antibodies confer immunity. We've all been assuming herd immunity is the key, either by vaccine or the "we all get it, but slowly enough to not overrun the healthcare system" method.
Right now we're on the edge of a precipice. My read of "the people" is they will hold off a bit longer if some reasonable-sounding fact-ish based plan comes out soon. It can be a little wrong, but it has to be credible. Knowing how many people have had it, and whether or not those people are now safe, is imo the two biggest components of planning the next steps. If we can't get credible answers to those questions soon, I believe the population will just start making decisions based on hunches/beliefs/feelings/etc. Some will remain isolated, others will rebel. It won't be pretty.
No one ever said you wouldn't get this though. The whole idea from the get go was to prevent a run on the hospitals, not to prevent society from catching this.
Every passing day more data and studies are reflecting the realities of this disease not being as deadly as imagined. So perhaps, just like chickenpox, its better to just get it as a kid then to face it later as an adult.
I'm growing more sympathetic to the wild theory that this is actually no worse than the endemic coronaviruses, and the deaths we're seeing are just what happens when a bad cold hits a population that didn't build immunity to it in childhood.
