As with flu, the statistics for WuHan can only be partial and skewed toward mortality. Many, perhaps most are never reported because they consist of a day or two of sniffles.
True, but, to keep everything in perspective......
The correct measurement of lethality is deaths / cases.
You will have just as much doubt about the number of Wuhan cases as the number of flu cases because both will have very mild instances.
Cases that need the hospital the data so far shows Wuhan about 68 times more lethal than flu. Flu is not a non-human animal virus. The human body doesn’t know what to do with Wuhan. Keeping the patient alive long enough for defenses to mount is much more challenging than with flu.
People die from flu? Who knew? Trump Flu? //sarc//. The very young or old (people with suppressed or not developed immune systems) are more likely to die from flu, or in the case of today’s hysteria, Coronavirus.
