The Talmud and Leprosy

The Talmud indicates that a leper could not come within 4 cubits of any Israelite or 100 cubits if there was an east wind blowing. The Mishnah indicates that any contact with a leper, his dwelling, or any of his possessions would make a person ceremonially unclean. According to Leviticus 13:45 a leper was commanded to cry "unclean, unclean" when he was near any Israelite. According to Josephus there were many lepers in the land and they were forbidden to come into a city at all or to live with any anyone in a house. The leper was to be treated as a dead person.
