India struggles to curb leprosy transmission

1. At a Glance

• Leprosy (Hansen's disease) is a chronic infectious disease. India's programme to control it is the National Leprosy Eradication Programme (NLEP). Its current goal is zero transmission by 2027, three years before the SDG 2030 deadline. [2]
• The paradox: the national prevalence rate is 0.56 per 10,000, below the elimination threshold of <1 per 10,000. Even so, new cases, child cases and disability are all running well above what the programme projected for 2025-26. [1]
• Why UPSC cares: the topic links neglected tropical diseases, SDG 3, health equity and stigma (tribal and poor regions), and how to measure "elimination" against "interruption of transmission". It is a strong GS-II health and governance case study.

2. Why in the News

• An analysis in The Hindu (8 Oct 2026, p.13) finds that India's leprosy programme fell short of several 2025-26 projections. [1]
• New cases: 91,783 in 2025-26. That is 41.2% above the projected 65,000. [1]
• New child cases: 91.6% above projection. Child cases signal that transmission is still active in the community. [1]
• Grade 2 Disability (G2D) rate among new cases: 1.34 per million, against a projected 1 per million. [1]
• Districts that have interrupted transmission: only 148 have done so provisionally, against a projected 300. [1]

3. Background & Evolution

• † The National Leprosy Control Programme began in 1955. It was converted to the NLEP in 1983 when Multi-Drug Therapy (MDT) was introduced.
• † India reached elimination as a public health problem (prevalence <1/10,000) at the national level in December 2005.
• 30 January 2023: the National Strategic Plan (NSP) & Roadmap for Leprosy 2023-2027 was launched with the target of zero transmission by 2027. [2][5]
• The NSP sets out implementation strategies, year-wise targets, public-health approaches and technical guidance. [2]
• Shift in focus: from prevalence-based elimination to interruption of transmission at district level. [2][3]

5. Multi-Dimensional Analysis

Social

• Five States/UTs (Chandigarh, Delhi, Chhattisgarh, Jharkhand, Odisha) account for 42.5% of G2D cases. This points to late detection among marginalised and migrant groups. [1]
• The high-burden States (Chhattisgarh, Jharkhand, Odisha) have large tribal populations and remote areas where access is poor. [1]
• Stigma delays people from coming forward. The NSP makes "zero stigma & discrimination" a core pillar. [2]

Administrative / Governance

• Metric illusion: the national PR is below 1/10,000, but that average hides 114 districts that are still above it. [1]
• Interruption of transmission: 148 districts have achieved it, against a target of 300. The 2027 zero-transmission goal looks hard to reach. [1][2]
• Delayed detection: a G2D rate of 1.34/million means cases are found only after visible disability has set in, which points to weak active case finding. [1]
• Digital surveillance through Nikusth 2.0 is meant to improve real-time reporting. [2]

Scientific / Technological

• LPEP with Single-Dose Rifampicin breaks the chain among household and neighbourhood contacts. [1][2]
• Child cases are the key epidemiological signal: the NSP defines interruption as zero new child cases for 5 years. [2]

Ethical / Legal

• † Several old laws discriminated against people affected by leprosy, for example as grounds for divorce. Most were repealed after Law Commission Report No. 256 (2015).
• A rights-based approach overlaps with the Rights of Persons with Disabilities Act, 2016 († leprosy-cured persons are listed among the disabilities).

Urban dimension

• High G2D rates in Chandigarh and Delhi suggest late detection among urban migrant and slum populations. Leprosy is not only a rural disease. [1]

6. Recent Developments (last 12-18 months)

• 5 Oct 2025: PIB backgrounder "Leprosy in India: The Road to a Disease-Free Future" reiterates the 2027 zero-transmission goal under the NSP. [3][4]
• 2025: Parliament reply (PIB) gives an update on NLEP and NSP implementation. [2]
• End of March 2026: national PR stands at 0.56/10,000. [1]
• 2025-26 results: 91,783 new cases, 1,945 G2D cases, and only 148 of a projected 300 districts with interrupted transmission. [1]
• 8 Oct 2026: The Hindu data analysis highlights the programme's shortfalls against NSP projections. [1]

7. Prelims Hooks

• The NSP & Roadmap for Leprosy covers 2023-2027 and was launched on 30 January 2023. [2]
• India's target is zero transmission of leprosy by 2027, three years ahead of the SDG 2030 deadline. [2]
• "Elimination as a public health problem" means prevalence below 1 case per 10,000 population. [1]
• District-level interruption of transmission means zero new child cases for at least 5 consecutive years. [2]
• Nikusth 2.0 is the web-based portal for reporting leprosy cases. [2]
• LPEP is delivered by giving contacts Single-Dose Rifampicin (SDR). [1][2]
• India's leprosy PR at the end of March 2026 was 0.56 per 10,000. [1]
• Chhattisgarh had the highest PR among States/UTs in 2025-26 (1.66/10,000). [1]
• Chandigarh had the highest G2D rate in 2025-26 (13.54 per million). [1]
• India reported 91,783 new leprosy cases in 2025-26. [1]
• 14.8% of districts had PR above 1/10,000 in 2025-26, down from 18.6% in 2013-14. [1]
• G2D (Grade 2 Disability) means visible deformity at diagnosis. It is used as a marker of late detection.
• National Anti-Leprosy Day falls on 30 January. [5]

8. Is the Jump in Cases a Failure, or a Sign of Better Searching?

• The strongest defence of the programme
• The government now goes looking for hidden cases instead of waiting for patients to come in.
• Under the Leprosy Case Detection Campaign (LCDC), health workers search house to house twice a year in high-endemic States (States where the disease is common) [7].
• LCDC alone confirmed 27,428 new cases in 2024-25 [7]. All of these people already had the disease and were simply never counted before.

• So part of the 91,783 figure is old, hidden disease now coming to light. More cases found can mean a better search, not more spread [1][7].

• What this defence gets right

• When a country searches harder, its case count first goes up before it comes down.

• Penalising a district for finding more cases would push officials to stop searching.

• Why it still does not explain the shortfall

• A better search should find people earlier, before damage sets in. Then the G2D rate (visible deformity at the time of diagnosis) should fall fast.
• It is still 1.34 per million, above the target of 1 [1].
• New child cases are 91.6% above projection [1]. A child with leprosy caught it recently, so these cannot all be old hidden cases. The infection is still spreading now.
• Only 148 of 300 projected districts have stopped transmission [1]. That count depends on child cases, not on how hard anyone searched [2].

9. Why the National Average Has Barely Moved in Six Years

• Prevalence is flat
• In 2020, India's prevalence rate (PR) (the number of people on treatment at a point in time) was 0.57 per 10,000 [8].
• In March 2026, it was 0.56 per 10,000 [1].

• The national number has stayed under 1 for twenty years, so it no longer pushes anyone to act.

• The programme itself flagged this trap

• The Central Leprosy Division's own list of problems includes the "misinterpretation on elimination and eradication of leprosy" [8].

• Once India was declared to have "eliminated" leprosy, many people took that to mean the disease was gone. Search efforts and public attention went down.

• Disability is improving, but too slowly

• The G2D rate fell from 1.96 per million (2020) to 1.34 (2025-26) [8][1].

• The WHO Global Leprosy Strategy 2021-2030 wants a 90% cut in this rate by 2030 [6]. At the present pace, India will miss that.

• The burden sits in one belt

• In 2020, 118 districts (17%) were classed as high-endemic [8].
• In 2025-26, 114 districts were still above the PR target [1].
• So the hard core of high-burden districts has hardly shrunk. Most of the progress has come in districts that already had little leprosy.

10. Where the Chain Breaks: From Finding a Case to Protecting the Family

• The search happens only twice a year
• LCDC runs as a campaign in high-endemic States, twice a year [7].

• Leprosy develops slowly and quietly. A person who misses both rounds may go undetected until deformity appears. This is what the G2D rate measures [1].

• Contacts are the weak link

• Stopping spread depends on giving Single-Dose Rifampicin (SDR), a one-time preventive tablet, to close contacts of every patient [2][8].
• The ministry itself lists "control of contacts" and "laboratory services" as technical challenges [8]. If a diagnosis cannot be confirmed, or a patient's contacts are never traced, the household goes unprotected.

• Rising child cases show that infection is still passing inside families and neighbourhoods [1].

• Too few trained, motivated workers

• The ministry names "human resources capacity and motivation" and "referral services and linkages" as operational problems [8].

• Leprosy is now rare in most districts. A general health worker may see one case in years, so they miss the early pale patch on the skin.

• Migrants slip through

• During COVID-19, the programme had to specially track MDT (Multi-Drug Therapy) treatment of migrant labourers [8].
• A worker who moves cities in the middle of treatment can drop out. This fits the high G2D rates in Chandigarh and Delhi [1].

11. What Should Be Done, and By Whom

• MoHFW: use the school health check-up to find child cases every year, not only twice-yearly campaigns
• Leprosy screening is already part of RBSK and RKSK (child and adolescent health programmes covering ages 0-19) [8].

• If every positive child in these check-ups is linked to SDR for the whole household, the child-case signal turns into action within the same year.

• State health departments: make urban screening real

• The ministry has planned leprosy screening under the National Urban Health Mission (NUHM) for slums and areas on the edge of cities [8].

• Chandigarh and Delhi have the worst G2D rates in India [1]. These two should be the first test of whether NUHM screening actually finds people early.

• MoHFW: add leprosy checks to the Ayushman Bharat screening of adults over 30

• The programme already counts this screening as a step towards convergence (joining leprosy work with other health services) [8].

• Doing so means leprosy checks would no longer depend only on separate campaigns.

• Central Leprosy Division: judge districts by the WHO measures, not the PR

• The WHO Global Leprosy Strategy 2021-2030 measures success by fewer new cases (70% cut), fewer G2D cases (90% cut) and zero locally acquired cases [6].

• District rankings should use child cases and G2D rate. A district should not get credit just for a PR below 1.

• District health officers: investigate every G2D case

• Every new case with visible disability should be treated as a missed opportunity: find out why that person was not caught earlier.
• The NLEP already calls for detailed investigation of all Grade II Disability cases [8]. If those findings are acted on, the late-detection gaps can be closed.

12. Anchors for Answers

• Data: PR 0.57/10,000 in 2020 [8] vs 0.56 in March 2026 [1]. The national average has hardly moved in six years.
• Data: G2D rate fell from 1.96 per million (2020) [8] to 1.34 (2025-26) [1], but is still above the target of 1.
• Data: 27,428 new cases found through LCDC in 2024-25 [7]. Active search finds a large hidden burden.
• Report/Committee: WHO Global Leprosy Strategy 2021-2030 targets a 70% cut in new cases, a 90% cut in the G2D rate and 120 countries with zero locally acquired cases [6]. Law Commission Report No. 256 (2015) on discriminatory laws (from the note; verify).
• Law/Case: Rights of Persons with Disabilities Act, 2016 (leprosy-cured persons listed as a disability category, from the note; verify).
• Comparison: WHO judges success by new cases, G2D and zero locally acquired cases, not by prevalence [6]. India's 2005 "elimination" used the PR, which is why it misleads.
• Scheme: RBSK/RKSK school and adolescent screening, NUHM urban screening and Ayushman Bharat population screening (30+) are channels for finding leprosy early [8]. LCDC, FLC and the Sparsh awareness campaign are the NLEP's own campaigns [7][9].

• GS-II: "Issues relating to development and management of Social Sector/Services relating to Health"; "Welfare schemes for vulnerable sections".
• GS-III (secondary): Science & Technology, specifically disease surveillance and digital health.
• GS-IV (ethics case studies): stigma, dignity and discrimination.
• Possible question stems: 1. Despite achieving elimination of leprosy as a public health problem at the national level, India continues to report high new and child cases. Examine the gaps and suggest measures to achieve zero transmission by 2027. (15 marks) 2. Aggregate health indicators often mask regional disparities. Discuss with reference to India's leprosy programme. (10 marks) 3. Social stigma is as significant a barrier as medical access in eliminating leprosy. Critically analyse. (10 marks)

15. NCERT Concepts to Revise

• Rights of Persons with Disabilities Act 2016 (Polity): The note says this law lists leprosy-cured persons as a disability category, linking disability rights to the rights-based approach.
• Slum (Geography): High disability rates in Delhi and Chandigarh point to late detection among crowded urban slum and migrant populations.
• Equity (Geography): Leprosy burden falls on poor, tribal and remote groups with weak access, showing unequal access to health care.
• Governance (Polity): The gap between the national average and 114 lagging districts is a programme-delivery and governance problem.
• Development (Geography): Health outcomes like leprosy control are part of broader development and well-being, including SDG-linked goals.

16. Common Errors / Trap Areas

• "Elimination" ≠ "eradication" ≠ "zero transmission". India met elimination (PR <1/10,000) nationally, but the disease is neither eradicated nor has transmission stopped. [1][2]
• Target year confusion: India's target is 2027; the SDG / WHO target is 2030. [2]
• Wrong metric: interruption of transmission is defined by zero child cases for 5 years, not by the PR. [2]
• "Leprosy is purely rural or tribal": Chandigarh and Delhi have the highest G2D rates. [1]
• Name trap: the programme is the National Leprosy Eradication Programme, not "Elimination" or "Control" ("Control" was the pre-1983 name).
