Leprosy, also known as Hansen's disease, is a chronic infectious disease caused by Mycobacterium leprae. The infection primarily affects the skin, peripheral nerves, eyes, and the lining of the nose. If left untreated, it can lead to nerve damage, muscle weakness, and disability. However, leprosy is curable with appropriate multidrug therapy, and early diagnosis is important to prevent complications and long-term disability.
What are the Different Types of Leprosy?
Leprosy is classified based on the number of skin lesions and nerve involvement:
- Tuberculoid Leprosy: Few lesions and limited nerve damage the body's immune response is strong.
- Lepromatous Leprosy: Many skin bumps and widespread nerve damage; the immune response is weak.
- Borderline Leprosy: Features of both types often unstable.
- Indeterminate Leprosy: Early form with one or two light patches may evolve into a more definite type.
What are the Leprosy Symptoms and Warning Signs?
Symptoms develop gradually over time. Recognising the early signs can help in managing the disease effectively.
Common symptoms include
- Light or dark patches on the skin with reduced sensation
- Numbness in hands, feet, or affected skin areas
- Weakness in muscles, especially in hands and feet
- Dry, flaky, or scaly skin
- Nosebleeds or stuffy nose
In advanced stages, one may experience
- Ulcers on the feet
- Thickened skin, especially on the face and ears
- Clawing of fingers or toes
- Loss of eyebrows or eyelashes
- Eye issues like dryness or even vision loss
What are the Common Causes and Risk Factors of Leprosy?
Leprosy is caused by Mycobacterium leprae, a slow-growing bacterium. It spreads through droplets from the nose and mouth of untreated patients, usually during prolonged close contact.
Risk factors include
- Living in areas where leprosy is common
- Having close contact with an infected person
- Weakened immunity (e.g., due to malnutrition or other illnesses)
- Genetic susceptibility
Note: It is not spread by touch, sharing food, or casual contact.
When to See a Doctor for Leprosy?
Persistent skin patches with reduced sensation, unexplained numbness, muscle weakness, or thickened nerves should be evaluated by a Dermatologist, Infectious Disease Specialist, or Neurologist.
You should see a doctor if you experience:
- Skin patches with loss of sensation
- Numbness in the hands or feet
- Progressive muscle weakness
Seek prompt medical attention if:
- Rapid nerve function loss develops
- Eye symptoms or vision changes occur
- Ulcers or deformities begin to develop
Early treatment can prevent permanent nerve damage and disability.

How Leprosy is Diagnosed?
A dermatologist can often diagnose leprosy through a physical exam, but certain tests help confirm the condition:
- Skin Biopsy: To look for the bacteria under a microscope
- Slit Skin Smear Test: Especially useful for multibacillary leprosy
- Nerve Testing: To assess any loss of sensation or function
At Medicover, our dermatology team uses precise tools and clinical expertise for accurate and early diagnosis.
What are the Treatment Options for Leprosy?
Leprosy can be cured completely with the right medication. The World Health Organization recommends Multidrug Therapy (MDT) which combines antibiotics:
- Rifampicin
- Dapsone
- Clofazimine
Treatment Duration
- 6 months for paucibacillary cases
- 12 months or more for multibacillary cases
Once treatment begins, patients quickly become non-infectious. It is crucial to complete the full course to prevent relapse or resistance.
Additional care
- Anti-inflammatory medicines to reduce nerve pain
- Surgery for deformities if needed
- Physiotherapy to regain strength
