Recently, the Maharashtra government has officially declared leprosy a “notifiable disease.”

About Leprosy:

  • Leprosy is an infectious disease caused by a type of bacteria called Mycobacterium leprae.
  • It is also known as Hansen’s disease.
  • It primarily affects the skin, peripheral nerves, eyes and other organs.
  • It is a neglected tropical disease (NTD) which still occurs in more than 120 countries, with around 200 000 new cases reported every year. 
  • It was declared notifiable in 2005 uniformly under the National Leprosy Eradication Programme (NLEP), Union Ministry of Health and Family Welfare.
  • Transmission of Leprosy
    • 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.
  • Symptoms of Leprosy
    • 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.
  • Treatment of Leprosy
    • 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).
