I've got to be honest: when I think of leprosy, I think of Jesus. Often regarded as a vestige from a bygone era, I was surprised to learn (from a reader, in fact) that leprosy still afflicts nearly two million people worldwide. We now call it Hansen's disease, but referring to it by its pseudonym has done little to dispel myths or stigma surrounding this ancient affliction.
