Interesting, remember when I was a boy there were always children about with calipers after having polio. They just "got on with it" as they had no choice in those days. There was always talk of the iron lungs and the children who were in them. My mother made sure we were always up to date with vaccinations (mid 1950's).
I know of only one person now who had had polio, in his 70's now, fully mobile but still requires some kind of caliper and a stick to walk.
I knew about post viral fatigue and other problems but had never heard of post-polio syndrome before. Does not bode well for younger people who contract the latest virus when they get older.
