This Dermatologist says armadillos can carry it. The disease grows better at lower temps than most mammals innards. Which why it mostly affects skin in people. Armadillos have cooler. Body temps than most mammals, so are good hosts for it. And BTW, what we now call leprosy likely had nothing to do with what the Bible called it. It can leave diagnostic changes in bones and none such ever found in holy land have dated earlier than 1st century AD. With the oldest such buried in a way to suggest judaeans then considered it a novel scary disease. Bony changes showing what we now call leprosy have been dating back to biblical times, but not then in the biblical area. Biblical “leprosy” was likely multiple different (by modern criteria) diseases sharing prominent skin changes.
