I honestly believe it could be a mixture of both, but we need to see how things progrsss over the next few days before we jump to any conclusions, I’ve just looked at most major countries in Europe and I haven’t yet found one place that halved its death number the following day, seems a real anomaly there must be something behind it.
Edit: also, no new infection numbers, very strange.

No, sorry I don't mean I don't believe the figure. I just feel there's something else going on here. Maybe a treatment being used here that's not being used in Spain and Italy, maybe some truth in the theory that half the country has already had it, I don't know what exactly.
Or maybe we do just have one of the best health services in the world still?
