Nice post, otto.
But how does the coronavirus pandemic compare to the 1918 swine flu and past seasonal flu?
Very hard to know since actual coronavirus numbers are generally withheld from the public. I've previously noted that the Massachusetts Dept. of Health has been very open about their collected numbers (every state has these numbers).
Looking at a plot of past swine and seasonal flu data, I have plotted the Massachusetts CV deaths per 100,000 population per age group numbers on the graph (red) for comparison. I have actually doubled the current MA numbers to represent an estimate of what might be expected in exiting this potential first wave (maybe by July). Here is a plot of the waves of the 1918 swine flu for context.

Now for the comparison data plot of CV vs swine flu and seasonal flu.

Difference between the influenza mortality age-distributions of the 1918 epidemic and normal epidemics – deaths per 100,000 persons in each age group, United States, for the inter-pandemic years 1911–1917 (dashed line), pandemic year 1918 (solid line), and coronavirus 2020 (red line).
First, the overall death rates are much lower today. That is the result of better preventative guidelines and improved healthcare, among many other things, IMO. These are different eras.
What stands out is that coronavirus is of little danger to children and the general working class (if you ignore one-off media stories), and a real danger to older people. Not on this graph, but we also know pre-existing health conditions are the second critical risk group. 98% of coronavirus deaths in MA have had underlying health issues.
What is the point? The point is that with CV, we know exactly who is at risk and in the past, including the recent flu seasons, we had less knowledge of the risk groups.
I expect there will be a lull in cases over the summer like with the swine flu and typical pandemics, and there is the expectation of a second wave of CV in the late fall (how can you have a second wave without a lull?).
How will America approach the second wave, without a vaccine but with many months to prepare? We should know if previous CV exposure gives future immunity, and this is expected (although not proven).
I am certain there will not be a repeat of this lockdown. There is a majority of the population that is close to no risk from coronavirus. Herd immunity and greatly improved protection of all risk groups is a potential approach. And this may save a lot of lives and minimize collateral damage.
