'''Leprosy''' is a chronic infectious [[disease]] caused by an infection with the [[bacteria]] ''Mycobacterium leprae''.  It is also known as Hansen's disease, named after its creator Gerhard Hansen. Leprosy mainly affects the [[skin]], the peripheral nerves, mucosa of the upper respiratory tract and the [[eye]]s. It can affect all ages and both sexes. Incubation can last anywhere between three months and 40 years, with the average incubation period lasting three to five years. Leprosy is transmitted from one untreated person to another via the respiratory tract or skin. Leprosy is curable and if detected early and treated with a prescribed duration of drug therapy, leprosy will not cause any permanent disability.

Leprosy is one of the world's oldest diseases, tracing back to the ancient civilizations of [[China]], [[Egypt]] and [[India]]. Leprosy was also rampant during the 13th century in [[Europe]]. Historically, it is one of the most stigmatized diseases with a reputation of being highly contagious, disfiguring and incurable. In the past leprosy sufferers were banished to ''[[leper colony|leper colonies]]''. Unfortunately, this practice still exists is some countries today, even though leprosy is now curable and is not considered highly contagious.
