Context
- India recorded 3,832 new child leprosy cases in 2025–26, including 37 cases with Grade-2 Disability (G2D), raising concerns over progress towards interrupting leprosy transmission at the district level by 2027.
Child Leprosy as a Marker of Ongoing Transmission
- Leprosy or Hansen’s disease is a chronic bacterial infection caused mainly by Mycobacterium leprae, affecting the skin and peripheral nerves.
- It spreads mainly through prolonged close contact with an untreated patient and is curable with multidrug therapy (MDT).
- New cases among children below 15 years are important because they indicate recent and continuing transmission within the community.
- Grade-2 Disability (G2D) means visible disability has developed before diagnosis, making it an indicator of delayed detection and treatment.
- The presence of G2D among children therefore signals a dual failure: ongoing transmission plus late diagnosis.
- In 2025–26, India recorded 3,832 child cases, well above the NLEP target of 2,000, showing that transmission remains active in several pockets.
- India also recorded 91,783 new leprosy cases overall, while the national G2D rate remained above the programme target of less than one case per million population.
- The burden is concentrated particularly in high-endemic districts of Chhattisgarh, Jharkhand, Maharashtra, Odisha and Madhya Pradesh.
Persistent Transmission and the Challenge to India’s 2027 Elimination Goal
- Ambitious elimination benchmark: Under the National Strategic Plan for Leprosy 2023–27, interruption of transmission requires zero indigenous child cases for five consecutive years, along with zero disability among newly detected children.
- Persistent programme gap: Continued detection of child cases and G2D shows that India has reduced overall prevalence without fully breaking community-level transmission chains in endemic pockets.
- Delayed detection remains critical: Visible disability at diagnosis suggests missed opportunities for early identification, allowing infection to progress before treatment begins.
- Geographic concentration: The challenge is increasingly district-specific rather than uniformly national, requiring intensified action in high-burden and hard-to-reach areas.
- Targeted programme response: NLEP relies on active case detection, household contact surveys and focused campaigns to identify hidden cases before disability develops.
- Social barrier: Stigma and discrimination can delay self-reporting, making community awareness and early treatment as important as medical surveillance.
- Strategic priority: Achieving the 2027 goal therefore requires a shift from merely reducing prevalence to early detection, zero child disability and interruption of transmission in endemic districts.
FAQs
Q1. What causes leprosy?
Leprosy is caused mainly by the bacterium Mycobacterium leprae.
Q2. Why are child leprosy cases important?
They indicate recent and ongoing transmission in the community.
Q3. What does Grade-2 Disability indicate?
It indicates delayed diagnosis, with visible disability already present.
Q4. What is India’s 2027 leprosy goal?
India aims to interrupt transmission at the district level by 2027.
Q5. What are the main NLEP strategies?
They include active detection, contact surveys, focused campaigns and targeted action in high-burden areas.
