The mortality rate is much higher with Coronavirus compared to the flu. For Corona virus, WHO estimates this number around 2 to 3 percent, although Dr. Fauci of NIH estimates it closer to 1%. For the seasonal flu, it is approximately 0.1%.* And while the elderly are more prone to illness for both, Coronavirus will adversely impact the more healthy among that group.
* ”On the actual case fatality rate: "There's the number of cases that have come to the attention of healthcare providers. As of [Friday] morning, that’s like 98,000. Then on the other side, you have the number of documented deaths. That’s now like 3,700, 3,800. When you do that pure simple math, the deaths are the numerator, the cases are the denominator, that’s where you get the report from WHO that it’s somewhere between a 2% and 3% case fatality rate. However, when people do modeling … you have various assumptions that there are this many asymptomatic cases that never get counted. When you do that, you get a range of case fatality rates that always less than the actual numerical one because it always factors in relative proportions of asymptomatic ones that we don’t count."

Symptoms - symptoms for serious cases have required hospitalization with breathing support such as ventilation. As seen in Italy where there has been a spike of illness, this has resulted in a overburdened medical support system.
Infectiousness - Coronavirus has been determined to be about twice as infectious. Europe is midst of an increase number of cases.
Treatment - Coronavirus - no current vaccine and antivirals have had minimal impact.
And overall, there are just more unknowns about the Coronavirus, such as seasonal impacts, ability to reinfect, etc.
