I don’t think that will be anywhere near a majority of cases but if the fatalities are in the 1% range the “seriously ill with resulting complications” will probably be in that range pus or m in us a percent or two. Maybe another then percent will have subtle, permanent demonstrable disabilities, slight renal failure, cardiomyopathy, slight reduction of IQ. I would imagine, off hand some 90% of people who had it will be unaffected long term. Just shirtsleeve guesstimations.
As some will no doubt point out the cumulative disabilities probably won’t be much stress on the system because of the concurrent reduction in disability caused by motor vehicle accidents that have not occurred in the last 5 weeks.
“Maybe another ONE percent...”. Google got me again.
