reportedly 800 people have it around the global. 25 ppl died from it. So early numbers show a 3% mortality rate-worse than the spanish flu. That may seem unusually high. But at the onset most most people and medical professionals can think it is just an ordinary flu. So the people wouldn't be reporting unless they were serious cases (under-reporting), and initially the doctors may not be providing the requisite level of care. I expect the overall death rate from the disease to decrease now that everyone knows what is going on. But if it goes full pandemic, even with a smaller death rate, the death toll could be catastrophic.
