a curse

Thought to be a hereditary disease, a curse, or a punishment from God.

Leprosy patients were stigmatized and shunned. For example, in Europe during the Middle Ages, leprosy

sufferers had to wear special clothing, ring bells to warn others that they were close, and even walk on a particular side of the road, depending on the direction of the wind.
