Leprosy

Leprosy

Leprosy, also known as Hansen's disease (HD), is a chronic disease caused by the bacteria Mycobacterium leprae and Mycobacterium lepromatosis. Named after physician Gerhard Armauer Hansen, leprosy is primarily a granulomatous disease of the peripheral nerves and mucosa of the upper respiratory tract; skin lesions are the primary external sign. Left untreated, leprosy can be progressive, causing permanent damage to the skin, nerves, limbs and eyes. Contrary to folklore, leprosy does not cause body parts to fall off, although they can become numb or diseased as a result of secondary infections; these occur as a result of the body's defenses being compromised by the primary disease. Secondary infections, in turn, can result in tissue loss causing fingers and toes to become shortened and deformed, as cartilage is absorbed into the body.

Famous quotes containing the word leprosy:

    Gold? Yellow, glittering, precious gold?
    ...
    This yellow slave
    Will knit and break religions, bless th’ accursed,
    Make the hoar leprosy adored, place thieves,
    And give them title, knee and approbation
    With senators on the bench.
    William Shakespeare (1564–1616)

    The conscience of the world is so guilty that it always assumes that people who investigate heresies must be heretics; just as if a doctor who studies leprosy must be a leper. Indeed, it is only recently that science has been allowed to study anything without reproach.
    Aleister Crowley (1875–1947)
