About Leprosy

  • Leprosy, also known as Hansen’s disease, is a chronic infectious disease caused by a type of bacteria, Mycobacterium leprae.
  • The disease predominantly affects the skin and peripheral nerves.
  • Left untreated, the disease may cause progressive and permanent disabilities.
  • Apart from the physical deformity, persons affected by leprosy also face stigmatization and discrimination.
  • It is a neglected tropical disease (NTD) that still occurs in more than 120 countries, with more than 200 000 new cases reported each year.
  • It is known to occur at all ages, ranging from early childhood to old age.

Leprosy Transmission

  • The disease is transmitted through droplets from the nose and mouth of an untreated case of leprosy, containing the causative agent, following prolonged, close contact. 
  • The disease does not spread through casual contact (like shaking hands or hugging, sharing meals or sitting next to each other). 
  • The patient stops transmitting the disease upon initiation of treatment.

Leprosy Symptoms

  • It usually takes about 3 to 5 years for symptoms to appear after you come into contact with the bacteria that cause leprosy.
  • The main symptom of leprosy is disfiguring skin sores, lumps, or bumps that don’t go away after several weeks or months.
  • In some cases, body parts may lose their sense of touch and pain, increasing the likelihood of injuries such as cuts and burns.

Leprosy Treatment

  • Leprosy is a curable disease. 
  • The currently recommended treatment regimen consists of three medicines (dapsone, rifampicin and clofazimine) and is referred to as multi-drug therapy (MDT).
