This is a really difficult causal inference to make. There are so many confounding variables, from quality of healthcare to age demographic of infection, etc. It's also noisy. A nursing home getting infected and many older folks dying can completely spike the numbers. So I pretty much don't trust their statistics, especially if they are reporting 3 significant figures like "7.49 days doubling the number of fatalities". Even just misaligning the starts of the exponential growth phase of curves (does it begin at 1 case per 100k, 5, 100?) can throw this way off.
