It would be good to see ‘leper colony’ become some obscure term people have to research to understand.
It's odd, because while I was there, there were photos from a leprosarium in Hawaii, and that triggered long buried memories of my aunt, a retired Army nurse, who had talked about visiting the Hawaiian leprosarium when I was a little kid. After visiting I tried to find more stuff online to read about it, but it's a phenomenon for which there is very, very little info available out there.
From the tone of the posts here, I think the concept of a Leper Colony is joining polio in the history books. Good place for them.
