Overview
Leprosy is an infectious disease that has been known since biblical times. It is characterized by disfiguring skin sores, nerve damage, and progressive debilitation.
What are the symptoms of Leprosy?
Symptoms include:
- Skin lesions that are lighter than your normal skin color.
- Numbness or absent sensation in the hands, arms, feet, and legs.
- Muscle weakness
What causes Leprosy?
Leprosy is caused by the organism Mycobacterium leprae. It is not very contagious (difficult to transmit) and has a long incubation period (time before symptoms appear), which makes it difficult to determine where or when the disease was contracted. Children are more susceptible than adults to contracting the disease. Leprosy has two common forms, tuberculoid and lepromatous, and these have been further subdivided. Both forms produce sores on the skin, but the lepromatous form is most severe, producing large, disfiguring lumps and bumps (nodules). All forms of the disease eventually cause nerve damage in the arms and legs, which causes sensory loss in the skin and muscle weakness. People with long-term leprosy may lose the use of their hands or feet due to repeated injury resulting from lack of sensation. Leprosy is common in many countries worldwide, and in temperate, tropical, and subtropical climates. Approximately 100 cases per year are diagnosed in the United States. Most cases are limited to the South, California, Hawaii, and U.S. island possessions. Effective medications exist, and isolation of victims in "leper colonies" is unnecessary. The emergence of drug-resistant Mycobacterium leprae, as well as increased numbers of cases worldwide, has led to global concern about this disease.
Who is at highest risk?
Children are more susceptible than adults to contracting the disease.
When to seek urgent medical care?
In case you feel you are developing symptoms of leprosy refer your doctor.
Diagnosis
- Lepromin skin test can be used to distinguish lepromatous from tuberculoid leprosy, but is not used for diagnosis.
- Skin lesion biopsy
- Skin scraping examination for acid fast bacteria
Treatment options
A number of different antibiotics are used to kill the bacteria that cause the disease. Aspirin, prednisone, or thalidomide are used to control inflammation.
Where to find medical care for Leprosy?
Directions to Hospitals Treating Leprosy
What to expect (Outlook/Prognosis)?
Early recognition is important. Early treatment limits damage by the disease, renders the person noninfectious (you can't catch the disease from them), and allows for a normal lifestyle.
Possible complications
- Cosmetic disfigurement
- Permanent nerve damage
Prevention
Prevention consists of avoiding close physical contact with untreated people. People on long-term medication become noninfectious (they do not transmit the organism that causes the disease).
