Still on current numbers for death rate, as of today:
1.In Spain, 10 out of 100 infected have died.
2. In Italy, 12 out of 100 infected have died.
3. In Germany, which is the 4th country in number of confirmed cases, death rate is at 1.5%.
The above numbers give a good range for death rates as per the sampled population today. Of course, when a larger portion of the population is sampled, death rate will go down - but even if in the end it goes down to 0.5% or 1%, that is still several orders of magnitude higher than seasonal flu.
Wordlwide, with roughly 1,000,000 cases and 80,000 deaths, detah rate is 8%. Clearly, the death rate of this thing will end up being higher than others.
