Leprosy perhaps is one of the oldest documented human diseases and references can be found in texts written thousands years ago. The disease leaves marks on the skin mostly on limps and face that give a terrifying look to people infected. For this reason, lepers were treated as unclean and became outcasts of the society. The biblical perception of leprosy was that people infected were punished by the god for their sins. Today, we know that the disease is curable, is caused by bacteria and most of people are immune to it.
