I've also been getting some too scarily close fitting done (not sharing that, it'd be irresponsible, this is not my job and I'm nowhere close to being an epidemiologist). I think the number of confirmed cases in Spain is going to grow appallingly this week and morale is going to be hit hard. Tiny in comparison of what we'd get if we did nothing about it, though. I also think (and hope) it'll start getting much better after that if we're effectively quenching contagion. I hope the authorities share their models with the public in order to give them a fuller picture. That might help psychologically.
At any rate, you don't have to wait for anything, you can start implementing social distancing and careful personal hygiene practices right now.
The US already moving that way in baby steps but things will certainly get there. That it isn't there already is already bad but I can't see this taking more than a few more days.
You'll be in a situation where people will die by contagion of other people who isn't even aware they are infected. You might infect your loved ones.
If you don't lock down now, it will be bad.
