The total number of cases of nCoV are up 22% in the last day. This is the same as the day before. However, 98.8% of confirmed cases are still in China. This is pretty incredible.
It's interesting that very early on with a new disease there's two very different scenarios that present the same way:
Scenario 1
Many more people have the disease than are being measured, because they only have weak symptoms that appear to be e.g. a normal cold.
So the disease is more contagious and more widespread than is being measured, which means you have worse odds of containing it.
But, on the bright side, this means the case fatality rate is potentially much lower than it first looks.
Swine flu went this way.
Scenario 2
Your statistics are capturing almost all the cases that exist. So fewer people have the disease than you might fear, and you know who they are, and so you can quarantine them and do contact tracing. Furthermore, this suggests it's not spreading between people so readily. This means you have a good shot at choking off further spread.
But, on the other hand, it means the fatality rate is just as high as it initially looks. If 10% of the patients who come into hospital early die of the disease, then the same might be true of all the people who get it in future.
SARS, MERS and Ebola all went like this.
(And of course you can have an intermediate case where you're moderately under-counting cases and moderately overstating the severity of the illness.)
