Ok, massive new info dump from Karl Lauterbach (health political spokesperson of the german SPD (party on the center left)).
Current strategy is not just mitigation but suppression. Mitigation would be possible if we could bank on a vaccine / very viable treatment option within this year - we probably cant - vaccine development and production will take 18+ months, and thats already a very ambitious goal.
Target of suppression is to keep infection rate in the overall population - sustained (so for a long time) - well below 10%. In germany with case numbers of about 100 new infections every day - and thats sustained (you need social control meassures (distancing, chirurgical style masks, ..) to keep that sustained - and not breaking out into exponentiality again), you would then do individual follow ups. So isolate the people, talk to them, ask them which people they were in contact with and insist on them self isolating as well.
If you cant reach that low number for new infections (about 100 a day in germany), with sustained low growth rates, you cant do individual follow ups, which means much higher risks of new infection herds (groups of people) being undetected, and a far higher risk, of the epidemic breaking out large scale in fall once more.
If you dont manage to curb rate of new infections to that point, you are talking about massive societal fallout.
Two important points - by fall you will have overworked your clinic personal to a point where they basically clink out - and -
it isnt only death rate. Of the people with serious (as in heavy) progression of the illness - death figures arent the only important aspect to look at. Even with survivors you are talking about scar tissue in the lungs, reduced lung functions, higher risk of dementia, lower life expectancy - and much increased longterm costs.
edit: The factor here is about 5x that of every person dying from Covid 19.
About populations under risk.
In germany - if you go through all risk factors, about a third of the population is 'at risk'. Thats too many to isolate them as a group.
In the US up to 60% of your population.
(Thats people who smoked, are in treatment for high bloodbreassure and are over 60, people with asthma, preexisting conditions, and so on and so forth.)
-
He is in contact with health experts at Harvard, and they tell him, that the epidemic in the US is entirely uncontrolled at this point even in rural regions. Which means, high risk of it coming back stronger in the fall.
-
His comment on Sweden is, that they can maintain the current strategy of limited social isolation mostly because of population density (not very dense - especially in the north), and that they have low case numbers in cities as well - for now. Once their situation changes, they will/would change measures as well.
So short summery. Its dire.

A strategy of supression is what sourth korea operated on, btw.
And for the US, at this point thats already outside of the realm of possibility. (So all thats left is curbing the curve so it moves below health system capacity.)
