What is Leprosy?


Disease – The Medical Impact:

The bacterium is called Mycobacterium leprae. Discovered in 1873 by Gerhard Hansen, it is closely related to the bacteria that causes tuberculous. The organism has never successfully been cultivated on a slide or in a petri dish. For now, its growth is studied in nine-banded armadillos who, like people, are susceptible to leprosy.

The World Health Organization (WHO) reported 232, 857 new cases of leprosy in 2012 (the latest statistics available).

Most of these cases are in South-east Asia, Africa and South America. Ministries of Health throughout the world are working to eliminate leprosy through early detection and treatment. (Statistic from the WHO website)

Physical disabilities as a result of leprosy are just some of the potential lasting effects of the disease, even after treatment. Support like yours allows us to help overcome disease, disability and stigma - to bring hope to millions of lives.

Transmission:research donation

Researchers are not sure how leprosy is transmitted.

Though it is contagious, we know that leprosy is not transmitted through casual contact. In order to eliminate the disease, more research investigating transmission is necessary. Read more.

The World Health Organization partners with governments around the world to eliminate leprosy forever.

Disability – The Physical Impact:

Untreated, leprosy can cause…

  • Blindness
  • Skin, limb and nerve damage, eventually destroying a person’s ability to feel
  • Sensation loss, which can leave a person vulnerable to injury and infection
  • Muscle weakness and disability
  • Progressive physical changes in the way a person looks, it can damage hands, feet and facial features
  • Disfigurement, loss of fingers, limbs, and physical disability
  • Infertility or even kidney failure (some research suggests)
  • Loss of eyebrows and eyelashes

Indicator One: Visual Signs

- Patches or spots on the skin that could be darker or lighter than normal or slightly red.

Indicator Two: Loss of Sensation

- Loss of feeling and hair loss on the patches is common.
- On occasion, numbness in toes or fingers is the only sign of the disease.

Indicator Three: Tissue/Nerve Damage

- Damage to limbs, face, respiratory system and blindness could occur.
- Loss of feeling can lead to damage from untended wounds and infection.

Indicator Four: Nerve Enlargement

- Nerve enlargement has been identified as a key way of identifying leprosy.

Stigma – The Social Impact:Blog pop outs

Even after a person is cured of leprosy, the disease often continues to be an obstacle to living a normal life. Physical complications alone can prevent a person from working. People still face leprosy-related stigma, and even those once affected by leprosy can experience abuse and discrimination.

Social Consequences of Leprosy:

  • Extreme Poverty
  • Isolation from community and family
  • Stigma
  • Abuse
  • Discrimination
  • Depression
