Few things were harder than watching the wasting away of a human life as the bodies of the disease’s victims literally disintegrated. Medications and supplies were in short supply for a long time. Gradually, as the sufferers died and the disease was contained, the leper communities were scaled back and eventually closed.
The post-Christian cultural revolution in the West I have been describing in its Canadian context is the same which has swept Europe, the United States, and Western outliers such as Australia and New Zealand. Many of the European states have a barely breathing remembrance of Christendom, despite the appearance of oddities such as political parties calling themselves “Christian Democrats”. Churches are largely museums and cultural artefacts, even those still kept open for religious functions among the remnant of Christians. Such ceremonies are seen as living lessons in sociology and anthropology by their State benefactors.
