We don't know the figures though. All we know is the % of people who have died after testing positive. Not seen the figures today but yesterday that would have been 12 deaths against 560 ish positive testings comes out about 2%, but they admit that closer to 10,000 have had/got it. Use that figure and the death rate plummets. In China they say it was 3.4%, but its so infectious that there is no way they can test everyone. For a City the size of Wuhan, 11 million, there is no way there was only 90,000 cases. If you apply 20%, our estimate of likely infections here then Wuhans rate would be over 2 million cases and then the mortality rates plummet again, and get closer to seasonal flu.
The real problem is rate of infection and transmission. Seasonal flu occurs on a grand scale but over about 6 months. They are trying to stop similar numbers over 2/3 weeks.
Again not playing it down, but it's new enough for us to not know what we don't know.
