It is a coronoavirus so it behaves like one. The second infection pathway using the ACE2 receptor explains why it is deadlier than flu in certain populations of infected.
I heard Dr. Fauci say that the CFR for flu was .1% but I do not know how he got that. Is it this year? We are having a very mild year for the flu, so I heard.
Anyway the overall CFR for flu is telling you that the germ is killing the vulnerable just like coronaviruses and flus always do. The Spanish flu ran estimated 2.5% or higher, because that includes all the youth patients who died. That is not happening now with COVID-19. A CFR of .87%, the figure out of S. Korea, reflects the additional people killed by the second infection pathway.
Influenzas A (H1N1)pdm09 and B /Victoria were co-dominant,a rare once-in-every-20-year "double barrel" flu season. I had B/Victoria after the holidays and it damn near killed me.
"CDC estimates that so far this season there have been at least 36 million flu illnesses, 370,000 hospitalizations and 22,000 deaths from flu." CDC adds it was the worst flu season for children (H1N1 noted above) in a decade.
The silver lining here is that the US has a deep pool of immune-active individuals from a wild flu season. Italy did not.
