Leprosy is a chronic disease caused by a bacillus, mycobacterium leprae. Mycobacterium leprae multiplies very slowly. The incubation period is about three to five years but signs and symptoms can take as long as 20 years to appear. Leprosy is not highly infectious. It is transmitted via droplets from the nose and mouth or via the skin during close and frequent contact with untreated, infected persons.

Hansen's disease (named for Norwegian scientist Gerhard Armauer Hansen) is a chronic, infectious disease caused by a bacillus, Mycobacterium leprae. This disease usually affects the nerves, skin and eyes.

Yes, there are approximately 500 people in Canada diagnosed with leprosy. They are not infectious or a public health concern, and are being looked after by our health care system in the tropical disease units of major urban hospitals. Leprosy is not a highly contagious disease.

In 1982, the cure for leprosy was introduced. It is called MDT (Multi Drug Therapy) and is very effective. Our goal is to find leprosy early and cure it before it starts to do its awful damage. If leprosy goes untreated it will destroy the nerves in the hands, feet, and other extremities, which leads to deformities and disabilities such as the loss of use of fingers, feet and other parts of the body. Once treated, patients with leprosy quickly become non-infectious.

Yes, when untreated. However, even the most contagious patient becomes non-infectious within a few days or weeks of treatment. In addition, very few persons exposed to untreated patients contract the disease because only about five percent of the world's population is even susceptible to it.

Leprosy is transmitted by direct, person-to-person contact, usually repetitive, over a prolonged period of time.

In 2000, 738,284 cases of leprosy were identified worldwide; 91 in the United States. Between 1 million and 2 million people are believed permanently disabled by the disease. Ten countries account for 90 percent of cases: Brazil, Democratic Republic of the Congo,Guinea, India, Indonesia, Madagascar, Mozambique, Myanmar, Nepal and Tanzania.
