It seems like it’s difficult to get an accurate sense of the doubling rate right now, because of the confounding variable of increased testing.
People count bodies much more reliably in pandemics. I don’t trust our confirmed case telemetry data much, but I do trust the fatality data. Unfortunately it’s about a two to four week lagging indicator. But the fatality rates also currently show this to be spreading much, much faster than it ever spread in Wuhan.
Wuhan is what happens when the curve is flattened. Not what happens when you don’t.
The issue here is every death is attributed to COVID-19 if the virus is present even if the actual reason is some other underlying health condition. Given that most victims are elderly and had serious pre-existing conditions this leads to massive mortality rate over-estimation.
You also cannot reliably compare EU/US data with Chinese: initially most deaths and cases of pneumonia in China were attributed to other illnesses. Secondly, Chinese government is notorious for flat-out lying in their official stats.
That what you claim provably doesn't happen. Even old people simply don't die that fast otherwise, and we also have the data of the people who can't breath and have to be admitted to the hospitals: there were never that many cases before, happening that fast:
