As we keep learning more about long Covid, I expect that even if we stopped transmission of the virus today we’d still be seeing excess death and shorter lifespans for a long time. There are a lot of people walking around unaware of the organ damage they are living with due to minor bouts of Covid. Since the effects with subsequent infections seem to be cumulative, and more and more people getting repeated infections the next couple of decades are going to be a massacre with deaths from several different causes going up as people start to succumb to the effects of long Covid.
