Through the ages, people all over the world were condemned to live under cruel and inhumane conditions because of the disease. Even after effective treatment was developed in the mid-twentieth century, those affected by leprosy continued to be subjected to discrimination.

Timeline

The History of Leprosyfrom Ancient to Modern Times

  • Leprosy is one of the oldest diseases known to humankind

    Historical evidence suggests that it originated in East or West Asia, but recent genomic analysis has traced the disease to East Africa some 10 million years ago. Other theories claim that leprosy spread globally as early humans dispersed from Africa.

  • Leprosy spreads with invasion and expansion of empire

    Leprosy is thought to have spread along the Mediterranean coast with the campaigns of Alexander the Great and further into Europe with the expansion of the Roman Empire. Later migrations of Germanic tribes in the fourth century, the expansion of Islam from the eighth century, and the Crusades are considered to have contributed to further dissemination in Europe.

  • Misunderstanding traced back to Bible

    The image of leprosy and the entrenched misunderstanding of it can be ascribed to accounts in the Bible, or more precisely, to translations of the original text. In the Bible, “lepra” is synonymous with “impurity of sin.” Current scholarship indicates that both the terms “lepra” and “leper” were used as direct translations of the Hebrew term “zaraath,” a general term that referred to other skin afflictions, but not necessarily to leprosy.

    the Old Testament (King James Version).

  • Expansion of endemic areas in Europe, systemized discrimination, and aid efforts

    From the seventh to the fifteenth centuries, as leprosy became more prevalent in Europe, discrimination against those affected by the disease also grew, leading to their banishment from the community. Many facilities for the care of those affected came to function as places of quarantine and isolation from society. On the other hand, Saint Francis of Assisi devoted himself to the relief of those affected by leprosy by establishing “leprosy villages” where the residents’ freedom was respected. This was the start of efforts to aid those affected by leprosy by Elizabeth, a princess of the kingdom of Hungary, later canonized Saint Elizabeth of Hungary, and others in the thirteenth century.

  • The Retreat of Leprosy in Europe

    Starting in the 15th century, the number of persons affected by leprosy began to decline in Western Europe. Thereafter, although leprosy became prevalent at times, it had nearly disappeared by the 20th century. However, during the Age of Exploration, leprosy spread from Europe to other lands, and the number of those affected increased in Canada and the United States.

  • Start of Medical Treatment for Leprosy and Relief Work in Modern Times

    In 1873, Gerhard Armauer Hansen identifies Mycobacterium leprae as the bacterium that causes leprosy, marking the start of medical diagnosis and treatment of leprosy.In 1874, Wellesley Bailey, a Christian missionary, establishes The Mission to Lepers (now known as The Leprosy Mission or TLM), which provides care for people affected by leprosy including hospice care for elderly patients in many countries today, primarily in India and former British colonies.

  • The First Effective Treatment

    In 1941 the drug promin is administered for the first time at the National Leprosarium in Carville, Louisiana in the United States. Thanks to promin, leprosy becomes curable, but the drug can only be administered by injection and causes a number of side-effects.
