Leprosy was thought to be extremely contagious, though today we know it isn't contagious at all. Lepers were classed with heretics, Jews, homosexuals, prostitutes, pimps, and any others on the margins of society. When in public, lepers announced themselves by sounding bells and rattles to warn people away. Not allowed to touch food, in the marketplace, lepers had to point to their food choices with staffs.
