For a flu virus that is one month in its attack on the US population, the statistics you quote are unknowable.
The proper comparison is the swine flu for which there was also no vaccine or preventive treatment. Unfortunately the statistics are not as clear as those that are reported on this one on an hourly basis. For the swine flo, H1N1, the CDC still lists ranges for cases, hospitalization and deaths. The R0 therefore is not reliable. Likewise the R0 for the regular flu which has a vaccine and treatment drugs is not comparable.
I agree the covid 19 appears to be more lethal than the swine flu but that may be because it affects the older population rather than the H1N1 which in 2009-10 affected the young who generally have more resistance.
There is a lot we don’t know and I agree with other posters that we seem to have jumped to the scary side of projections and worst case scenarios. Like in many things moderation of our reactions is in order.
I say when the death curve reaches its tipping point in a week or two we remove all economic restrictions and let the economy recover.
This virus has been in the United States since December.
It is now April.
That is a hell of a lot longer than “one month.”
