Why “Leprosy Colonies” Still Exist Even After Cure — And What That Says About Us
Cured but still confined: life inside today’s leprosy colonies
Leprosy is now a curable and one of the least contagious infectious diseases, yet many people who have been cured still live in long-standing “leprosy colonies,” facing social exclusion, poverty and deep-rooted stigma. These settlements, once used to forcibly isolate people, have become home for thousands of residents like Alamelu in India’s Kalvari Nagar colony — people who took the medicine, beat the disease, but never fully escaped its social consequences.
Understanding why these colonies still exist in 2026 means looking beyond medicine and into history, law, economics and human psychology. It also means listening carefully to the people who live there, many of whom have chosen to stay not because of infection risk, but because the outside world still feels more hostile than any bacteria.
Leprosy today: curable, low-contagion, but still feared
Modern medicine has transformed leprosy (also called Hansen’s disease). Since the 1980s, the World Health Organization’s multidrug therapy (MDT) has been available worldwide, curing millions. According to WHO and recent data up to 2024:
- Most people have natural immunity and never develop the disease even if exposed.
- Leprosy is transmitted slowly, mainly through prolonged close contact, and is considered one of the least contagious infectious diseases.
- Someone who starts MDT quickly becomes non-infectious.
- Early treatment prevents most disability and deformities.
Yet the image that persists is one of disfigurement, danger and permanent exile. That gap between science and public perception is a major reason colonies still exist, even when nearly all residents are long cured.
“From a medical standpoint, there is almost never a reason to isolate a person with leprosy, and certainly not for life. Stigma — not infection — is what keeps people in colonies today.”

How leprosy colonies began: fear, law and forced isolation
Most leprosy colonies were created in the late 19th and early 20th centuries, when the disease was poorly understood and often compared to the most terrifying plagues. In many countries, authorities passed special laws allowing or requiring:
- Forced removal from families and communities.
- Confinement in leprosaria or colonies, sometimes for life.
- Restrictions on marriage, having children, or owning property.
- Separate schools, hospitals and even burial grounds.
In India, for example, the Lepers Act of 1898 allowed authorities to segregate and detain people with leprosy. Although such laws have since been repealed or reformed, their social impact lingers. Colonies that were once locked and guarded gradually “opened” but remained physically and socially separate places.
Residents built lives within these walls: marrying, raising children, organizing self-help groups, forming their own local economies. Over decades, the colony stopped being merely a place of punishment and became, for many, the only place they felt they belonged.
If they’re cured, why do people still live in leprosy colonies?
When you talk with residents in places like Kalvari Nagar, their reasons for staying are rarely about disease. They’re about survival, safety and dignity. Common reasons include:
- Deep stigma in surrounding communities — Neighbors may refuse to rent houses, share water sources or employ someone identified as “from the leprosy colony.”
- Visible disabilities — Even after cure, people may have lost fingers, toes or facial features. These permanent changes become “proof” in others’ eyes, fueling prejudice.
- Poverty and lack of options — Many residents are older, disabled or have limited education. The colony might be the only place with subsidized housing, NGO support and social services.
- Community and identity — After decades together, the colony is a tight-knit community. Leaving can feel like abandoning the only people who understand your story.
- Intergenerational roots — Children and even grandchildren of cured persons sometimes remain, not because they’re infected, but because land titles, social networks and livelihoods are centered there.
“Outside, they call us names and won’t touch us. Here, at least, no one is afraid to sit next to me.”

A closer look: life in Kalvari Nagar and similar colonies
Consider the story of a woman like Alamelu, who has lived in Kalvari Nagar leprosy colony for over two decades after time in another colony. Her journey, echoed by many others NPR and global health groups have interviewed, typically follows a pattern:
- Diagnosis and shock — Initial symptoms such as numbness or skin patches lead to a diagnosis that triggers fear in the family, often more than in the patient.
- Family rejection or “protective” distancing — Some families, frightened by myths of extreme contagion, encourage or force the person to move to a colony “for treatment.”
- Treatment and cure — With MDT, most people complete treatment within 6–12 months and are medically cured.
- Trying to return — When they attempt to go back, they may face suspicion: separate plates, refusal to share food, unwillingness to live under the same roof.
- Choosing the colony as home — Over time, they build friendships, join self-help groups and find small incomes in the colony — making it feel safer than an unwelcoming outside world.
For outside observers, it can be tempting to ask, “Why don’t they just leave?” But for someone who has been told repeatedly that they are unwanted in the outside world, staying can feel like the more rational, less painful choice.
What science actually says about leprosy risk and cure
To understand why the colonies are no longer medically necessary, it helps to clarify a few key scientific facts drawn from WHO, national leprosy control programs and peer-reviewed research up to 2024:
- Causative organism: Leprosy is caused by Mycobacterium leprae and, in some regions, M. lepromatosis.
- Transmission: Believed to occur mainly via droplets from the nose and mouth during close and frequent contact with untreated cases over months.
- Contagiousness: Compared with diseases like measles or COVID-19, leprosy is far less infectious. Casual contact (handshakes, sharing meals) is not considered a major risk.
- Treatment: WHO-recommended multidrug therapy is provided free in many countries and is highly effective. Once on treatment, a person becomes non-infectious quickly.
- Relapse: Relapse after adequate MDT is uncommon and usually treatable.
- Disability: Nerve damage can cause permanent disability if diagnosis and treatment are late, but that damage is not a sign of ongoing infection.
These facts are supported by decades of epidemiological studies and form the basis of policies against forced isolation. The continued operation of de facto leprosy colonies therefore reflects social and legal inertia, not medical necessity.
The real obstacles: stigma, law and economics
Dismantling the need for colonies requires tackling obstacles on several levels:
1. Social stigma and misinformation
Fear often comes from:
- Religious or cultural narratives that frame leprosy as a curse or punishment.
- Confusion between visible disability and active infection.
- Lack of exposure to accurate, up-to-date health information.
2. Discriminatory policies and gaps in protection
Although many explicit segregation laws have been repealed, remnants still exist in some legal systems — from barriers to marriage to job restrictions. Even where laws are progressive, enforcement can be weak, and people may not know their rights.
3. Poverty and lack of inclusive services
People affected by leprosy are disproportionately poor, often because of years of exclusion from education and work. Without:
- Accessible health care and rehabilitation,
- Skills training and employment opportunities,
- Affordable, non-segregated housing,
“Leaving the colony” can mean trading a fragile security net for homelessness and hunger.
Evidence-based solutions: what actually helps colony residents
Over the last two decades, NGOs, governments and grassroots groups have tested different ways to improve life in leprosy colonies and expand choices for residents. Interventions that show promise are multi-layered:
1. Rights-based legal reforms
- Repealing discriminatory laws related to marriage, employment and travel.
- Guaranteeing anti-discrimination protections in housing, health care and education.
- Issuing official documentation (ID cards, land titles) to residents, so they can access mainstream services.
2. Community-level education and engagement
Programs that pair medical facts with human stories tend to reduce fear the most. Effective approaches include:
- School-based sessions that explain what leprosy is — and is not.
- Involving cured persons as educators and community leaders.
- Public campaigns highlighting that leprosy is curable and low-contagion.
3. Economic empowerment from within colonies
Rather than telling people to abandon the colonies, some initiatives focus on improving incomes and autonomy where they are:
- Self-help groups and microcredit schemes.
- Training in accessible livelihoods (tailoring, crafts, small shops, agriculture where possible).
- Partnerships with ethical buyers to create fair markets for colony-made products.
4. Health care, rehabilitation and mental health support
- Regular checkups to prevent ulcers and secondary infections.
- Physiotherapy and assistive devices for mobility and daily living.
- Counseling to address trauma, depression and internalized stigma.
“Cure is only the first step. Full rehabilitation means restoring participation in family, work and community life.”

How individuals, health workers and policymakers can make a difference
Even if you live far from any leprosy colony, your attitudes and actions can influence how quickly stigma fades. Here are practical, realistic steps for different groups:
For the general public
- Use respectful language — say “person affected by leprosy,” not “leper.”
- Challenge myths kindly when you hear them in conversation or media.
- Support organizations that work on rights-based, inclusive approaches rather than segregation or pity-based charity.
For health professionals
- Stay updated on current leprosy guidelines from WHO or national programs.
- Provide clear counseling to patients and families about contagion and cure.
- Model non-discriminatory behavior in clinics — shared waiting areas, respectful touch, inclusive communication.
For policymakers and program designers
- Review and repeal any remaining discriminatory laws.
- Integrate leprosy services into general health systems instead of maintaining separate facilities.
- Involve people affected by leprosy in planning and monitoring programs — nothing about them without them.
Colonies then and now: from forced isolation to communities seeking choice
It helps to visualize how the role of colonies has changed over time:
The “after” picture is still incomplete. Genuine freedom of choice will only exist when staying in or leaving a colony are equally safe and respected options.
Moving beyond fear: towards dignity, rights and real choices
The continued existence of leprosy colonies is not a medical failure so much as a mirror held up to society. It reflects how long fear can outlive a disease, and how slow systems can be to correct past injustices. People like Alamelu may be cured in the eyes of medicine, but until they are also seen as neighbors, colleagues and full citizens, the story of leprosy is not finished.
You do not need to run a health program or write laws to make a difference. Every time you share accurate information, question stigmatizing language or support inclusive policies, you help shrink the gap between cure and acceptance. Bit by bit, that’s how we move from colonies of exclusion to communities of choice.
Call to action: Learn one new fact about leprosy today from an authoritative source and share it with someone else. Replacing fear with understanding is one of the most powerful treatments we have left to give.
