Whats important is not total positives but how many beds/ventilators/docs are available in a region when things suddenly spike.

In those moments, where 1000 people suddenly show up at the same time, outcomes start going down the drain.

But if the number coming in everyday are well within the regions capacity (cause of good social distancing/mask wearing/early travel bans etc OR/AND they have plans in place to handle Overflow/Sudden Surges such as Korea) then the story is very different.
