World Leprosy Day is observed on the last Sunday of January every year. It provides an opportunity for enhanced efforts and renewed commitment for elimination/eradication of the debilitating disease at the earliest. It focuses on the target of zero cases of leprosy-related disabilities in children. Early detection is prime focus to achieve this target, along with strengthening interventions to prevent leprosy transmission. Leprosy is also known as Hansen’s disease.
Leprosy affected 173 358 people globally at the end of 2016. Brazil, Indonesia and India are high-burden countries. Leprosy is curable and treatment in the early stages can prevent disability.
What is leprosy?
Leprosy is a chronic infectious disease caused by a bacillus, Mycobacterium leprae (M. laprae). The symptoms of the disease occur generally after a long period after getting infection on average 5 years as M. leprae multiplies very slowly. The disease mainly affects the skin, the peripheral nerves, mucosa of the upper respiratory tract, and also the eyes.
The disease is classified as paucibacillary (PB) or multibacillary (MB), depending on the bacillary load. PB leprosy is a milder disease characterized by few (up to five) skin lesions (pale or reddish), whereas MB is associated with multiple (more than five) skin lesions, nodules, plaques, thickened dermis or skin infiltration.
How is the disease spread?
Untreated leprosy-affected person is the only known source for transmission of the bacteria.
What are the signs and symptoms of leprosy?

What should be done in case of suspicion of leprosy?

What is MDT (multi drug therapy)?
MDT is a combination of different drugs as leprosy should never be treated with any single antileprosy drug.
National Leprosy Eradication Programme (NLEP)
The National Leprosy Control Programme was launched by the Government of India in 1955, after introduction of Multi Drug Therapy from 1982, the programme converted in to National Leprosy Eradication Programme (NLEP) in the year 1983 with the objective of achieving eradication of the disease from the country.
In 2005, though the elimination of leprosy at national level has been achieved; but still around 57% of the worlds' leprosy affected persons live in India. 554 districts (81.23%) out of total 682 districts have achieved elimination by March 2017.
Early case detection and treatment is the key to achieve elimination as detection of leprosy cases early in the community will lead to reduction of sources of infection in the community and also interrupt the transmission of the disease. ASHAs are helping in case detection and to assure complete treatment at community level; for that they are being paid an incentive.
