Study Notes
Causes and Transmission
- Causative Agent: Leprosy is primarily caused by the bacterium Mycobacterium leprae.
-
Transmission:
- Typically spread via respiratory droplets from an infected person.
- Prolonged close contact is often required for transmission; not highly contagious.
- Can also be transmitted through skin lesions or contact with contaminated materials.
Symptoms and Diagnosis
-
Symptoms:
- Skin lesions that may be lighter or darker than surrounding skin.
- Numbness in affected areas due to nerve damage.
- Muscle weakness, particularly in hands and feet.
- Eye problems, including blindness in severe cases.
-
Diagnosis:
- Clinical examination of skin lesions and sensory loss.
- Skin biopsy for laboratory confirmation.
- Serological tests and PCR may be utilized.
Treatment Options
-
Primary Treatment:
- Multi-drug therapy (MDT) combining rifampicin, dapsone, and clofazimine.
- WHO recommends MDT for all leprosy patients.
-
Duration:
- Treatment lasts from 6 months to 2 years depending on the severity.
-
Supportive Care:
- Management of complications like secondary infections.
- Rehabilitation for disabilities caused by the disease.
Historical Perspectives
-
Ancient History:
- Known since antiquity, often stigmatized as a divine punishment.
- References to leprosy found in ancient texts, including the Bible.
-
Middle Ages:
- Leprosy became more prominent and established leper colonies.
- The disease and its social implications influenced public health policies.
-
20th Century:
- The discovery of effective treatments changed perspectives.
- Increasing recognition as a medical condition rather than a moral failing.
Social Stigma
-
Discrimination:
- Those diagnosed often face societal rejection and isolation.
-
Cultural Factors:
- Many cultures associate leprosy with shame, leading to discrimination.
-
Impact on Life:
- Affects mental health, social interactions, and access to healthcare.
-
Efforts to Combat Stigma:
- Awareness campaigns and community rehabilitation programs aim to educate and integrate affected individuals back into society.

Leprosy: Causative Agent
- Leprosy is caused by the bacterium Mycobacterium leprae.
- Mycobacterium leprae is a slow-growing, acid-fast bacillus that thrives at a temperature of around 30°C (86°F).
- The bacterium primarily affects skin and peripheral nerves.
Leprosy: Risk Factors
- Weakened immune systems, such as those affected by HIV/AIDS, increase susceptibility to leprosy.
- Living in or near areas where leprosy is common increases exposure risk.
- Close physical contact with individuals who are not receiving treatment for leprosy can lead to transmission.
Leprosy: Transmission
- Leprosy is primarily spread through respiratory droplets, such as those produced by coughing or sneezing, from an infected individual.
- Prolonged physical contact with an infected individual is usually necessary for transmission.
- Leprosy is not highly contagious, and most people have natural immunity against the bacteria.
- Casual contact, bodily fluids, or sexual contact do not transmit leprosy.
- Mycobacterium leprae cannot survive long outside the human body.
Leprosy: Potential Sources of Infection
- Genetic factors may influence individual susceptibility to leprosy.
- Some studies suggest that armadillos might serve as a source of Mycobacterium leprae transmission.
