Wrong. They're highly flawed without an accurate denominator, but they're not nonsense. In fact I think they're actually pointing out that South Korea is the model to follow, as they've been testing like crazy (over 190,000 tests so far) and practicing effective social distancing/self-quarantining (so not in full lockdown).
While they have 7500 cases, the case rate is decreasing, plus their mortality rate is much lower than anywhere else (0.7% vs. 2-5% elsewhere), partly because of early identification/treatment and partly because the denominator is likely close to the real denominator, since they're finding mildly symptomatic people others aren't - and in fact the "true" mortality rate is probably close to SK's, but that's impossible to know without a lot more testing in these other countries.
Unfortunately, the US is not taking SK's approach, having completely bungled testing, which continues. It's unconscionable - this lack of testing is putting us at real risk of an Italy-style outbreak, especially in highly densely populated areas like DC to Boston, including NJ/NY, obviously.

@rutgersguy1 posted earlier in this thread and to the JHU tracker.
As an aside, I'd love to know what's going on in Germany. 1281 cases and only 2 deaths (~0.2% mortality rate). Data problem, weird outlier, lack of reporting?
