I didn't get numbers, but there were pics of headlines about how cases were on the rise. That confused me.
Are you saying here that cases in which it caused paralysis increased, as in the disease becoming more severe while there were same or fewer cases overall? I think there was a similar statement made at some point in the show . . . about more adults getting it relative to children, and more likely to get paralysis. Very misleading without numbers. No numbers on iron lungs, though they spent plenty of time talking about how horrible they were.
Honestly, though, it made me feel I need to be more educated on this subject, and polio in particular.
