Climate change is rewriting the boundaries between human spaces and snake habitats. Kerala’s deadly summer of 2026 is the latest — and most visible — chapter in a global crisis hiding in plain sight.

By Dipin Damodharan & Lakshmi Narayanan

The pencil drawing of a crowned king is still on the wall. It sits low — only as high as a small boy could reach. Dikshal was eight years old when he drew it, and eight years old when he died, bitten by a cobra that had slipped into his home in Chirayinkeezhu, Thiruvananthapuram, Kerala, seeking refuge from the punishing April heat. The snake was found later, hiding beneath a sewing machine.

His family had heard about the snakebite deaths spreading across Kerala. They had covered the gaps in their walls with sheets, reasoning that the heat inside would keep snakes away. They had never seen a venomous snake near their home before. When Dikshal woke complaining of a wound, his father Dileep could not make out the bite mark — there was only one puncture, not the two most people expect. The family rushed him to the nearest taluk hospital. Staff, uncertain whether it was a snakebite, did not administer anti-venom. By the time Dikshal reached the Medical College Hospital in Thiruvananthapuram, he had stopped breathing.

He was not alone. On April 18, eight-year-old Aljo from Kodakara in Thrissur district died after being bitten by a common krait while asleep. His brother Anoj was also bitten and remained in treatment. Within days, Kerala had recorded around five snakebite deaths in a single week, prompting widespread alarm. The answer to where all these snakes had suddenly come from, scientists and field workers say, is not sudden at all. Kerala lost 660 people to snakebites over the last decade.

The Physics of a Cold-Blooded Crisis

Snakes are ectotherms — cold-blooded creatures whose body temperature, metabolism, and behaviour are governed entirely by their external environment. Mithun A.S., an experienced snake rescuer who has worked across Kerala, explains it plainly: snakes depend entirely on external sources to maintain their body temperature. When the environment becomes too hot to sustain them, they do not adapt. They move.

“When temperatures cross a threshold, their metabolism accelerates, their need for food increases, and their natural burrows become unbearably hot,” Mithun says. “They have no choice but to come out and find somewhere cooler.”

In a Kerala summer that has broken decade-long heat records, that somewhere is increasingly inside our homes. As cold-blooded animals, snakes cannot regulate their body temperature or sweat, so they come out in search of cooler conditions. This is also the breeding season, which increases the likelihood of human-snake encounters.

What makes this moment particularly dangerous, Mithun notes, is the combination of heat and hunger. As metabolism speeds up, snakes need to feed more frequently. They are not only seeking cool shelter — they are also actively hunting. The two imperatives together drive them deeper into human territory than they would ordinarily venture.

The Microclimate We Built for Them

Krishnan T.J., a SARPA volunteer and snake expert with years of field experience across Kerala, has a precise term for what is happening to our homes. They have become microclimates — islands of thermal relief in an increasingly hostile landscape.

“Our bathrooms, our wells, our shaded corners — these are now the coolest places available to a snake within range,” Krishnan says. “The water sources outside are drying up. The burrows are overheating. The snake is not invading. It is surviving.”

The ecological concept behind this observation is microhabitat compression — as climate change narrows the zones where temperature, moisture, and shelter align, both humans and wildlife converge on the same shrinking refuges. In Kerala’s case, that refuge is often a tiled bathroom floor, the space beneath a bed, or the cool shadow of a sewing machine.

Krishnan points to the role of ornamental plants that climb walls, cracks in compound walls, and gaps in roofing as the entry points snakes most commonly exploit. “People grow decorative creepers along their walls and think nothing of it,” he says. “For a snake, that is a ladder.” The physical infrastructure of the Kerala home — designed for ventilation and shade in a warm climate — has inadvertently become optimal snake habitat.

Breeding Season and the Invisible Danger

Muhammed Anwar, nodal officer for Mission SARPA under Kerala’s Forest Department, adds a dimension that makes the current moment even more acute. April and May are not just the hottest months in Kerala — they are also when the Big Four venomous species hatch.

“The cobra, the krait, the Russell’s viper — this is their breeding season,” Anwar explains. “The hatchlings carry venom as potent as the adults. They are smaller and harder to see. And they are looking for exactly the same cool, damp spaces that the adults are.”

This convergence — record heat, accelerated snake activity, and a new generation of venomous juveniles dispersing across the landscape — is what transformed April 2026 into something beyond a seasonal spike. Anwar is particularly concerned about the structural features of Kerala homes that create easy access. “Ornamental plants climbing walls, gaps in compound walls, cracks where pipes enter — these are the highways,” he says. “And once inside, a snake will settle in the coolest spot it can find. That is often exactly where a child sleeps.”

Anwar has been at the centre of Kerala’s effort to reduce snakebite deaths since the SARPA programme launched in 2020. Chief Minister Pinarayi Vijayan has stated the programme’s goal as bringing snakebite deaths in the state to zero. The infrastructure — over 1,200 trained rescuers, a public app, and rapid response protocols— is among the most developed in India. But Anwar is candid about the limits of even the best response system when the underlying environmental conditions keep worsening.

India’s Hidden Epidemic

What is unfolding in Kerala is a concentrated, visible expression of something far larger across the subcontinent. India had an estimated 1.2 million snakebite deaths between 2000 and 2019 — an average of 58,000 per year. Over a quarter of those deaths were children under 15. Most occurred at home, in rural areas.

India accounts for approximately half of all snakebite-related deaths globally. Every year, an estimated 5.4 million people worldwide are bitten by snakes, resulting in as many as 138,000 deaths and three times as many cases of permanent disability. The World Health Organization classified snakebite as a neglected tropical disease in 2017, with a target to halve deaths by 2030. That target now looks increasingly difficult to meet — not because medicine has failed to advance, but because the climate is accelerating the problem faster than health systems can absorb it.

ssss

A landmark study published in PLOS Neglected Tropical Diseases in 2025, conducted by Indian and South Korean scientists, modelled the future distribution of India’s Big Four venomous species under climate change scenarios through 2080. Climate change is anticipated to significantly impact the distribution of snakes, leading to notable shifts in their habitats towards human-dominated landscapes. Under future scenarios, many northern and northeastern states — including parts of Assam, Manipur, and Rajasthan — are projected to show dramatically increased snakebite risk, in regions that currently have minimal suitable snake habitat. The snakebite map of India is being redrawn.

Did You Know? Kerala lost 660 people to snakebites over the last decade. India as a whole records between 46,000 and 58,000 snakebite deaths every year — more than any other country in the world, and roughly half the global total. The WHO has set a target to halve global snakebite deaths by 2030. Climate scientists say rising temperatures will make that target significantly harder to achieve unless the environmental drivers are addressed alongside the medical ones.

A 2025 cross-sectional survey published in Nature Communications found that nearly half of snakebite deaths in India occur outside hospital settings, falling overwhelmingly on rural, low-income households. Dikshal’s father told reporters the family had no safe place to sleep. Kerala declared itself free of extreme poverty in November 2025. The distance between that declaration and a child dying on a floor because his family could not afford a bed illustrates precisely how climate risk compounds existing vulnerability — not abstractly, but fatally.

A Global Pattern

The Kerala deaths of April 2026 are not anomalous. They are, in the language of climate science, a signal. Research published in The Lancet Planetary Health has established a direct correlation between rising temperatures and snakebite incidence. An Oxford University study projects that by 2050, 41% of the global population will be exposed to extreme heat events — with South Asia absorbing the largest share. Similar patterns of snakes moving into urban and peri-urban spaces have been documented in Australia and across sub-Saharan Africa as temperatures rise. According to a Climate Central analysis, in 47 countries, every single day of what scientists classify as “risky heat” was attributable to climate change.

The communities most exposed are precisely those least equipped to respond: rural households with limited access to antivenom, local hospitals uncertain about diagnosis, and families who cannot afford the beds and mosquito nets that would keep a sleeping child above the floor.

The Ecological Argument

There is a dimension of this crisis that public health conversations consistently underweight. Snakes are not the enemy. As Krishnan T.J. puts it: “The snake did not choose to come into your home. Your home became the safest place in its world.”

Snakes play a crucial ecological role by controlling populations of rats and rodents, which spread diseases like leptospirosis and plague and damage crops. The panic-driven killing of non-venomous species disrupts the very ecological balance that keeps those populations in check. Mithun A.S. has watched this cycle play out repeatedly. “Every summer, people kill dozens of harmless snakes out of fear. The rats multiply. The crops suffer. And the venomous snakes, the ones people are actually afraid of, keep coming — because the food is there.”

The WHO’s classification of snakebite as a neglected tropical disease recognised the medical emergency. What remains underrecognised is its ecological dimension — that snakebite mortality is, at least in part, a symptom of ecosystem breakdown driven by rising heat.

What Must Change

Muhammed Anwar’s immediate guidance is practical: maintain clean surroundings, remove woodpiles and debris from around homes, seal wall cracks and pipe gaps, trim ornamental climbing plants, use torches at night, sleep on raised beds with nets properly secured. If a snake is spotted, do not attempt to catch or kill it — call SARPA. If bitten, follow the Do it RIGHT protocol: Reassure, Immobilise, Go to Hospital, Tell the Doctor. Do not waste time on traditional remedies. The first hour is the only variable that can be controlled once a bite has occurred.

But beyond the immediate, Anwar, Krishnan, and Mithun all point to the same deeper truth: the precautions help at the margins. They do not address the driver.

As long as temperatures continue to rise — compressing the thermal refuges available to both humans and reptiles, pushing snakes into spaces that used to be ours alone — the encounters will multiply. Kerala’s SARPA programme is one of the most sophisticated snakebite response systems in India. It cannot outrun the climate.

The snakes entering Kerala’s bedrooms and hiding beneath its sewing machines are not acting out of aggression. They are doing what every living creature does when its habitat becomes uninhabitable. They are looking for somewhere cooler to survive.

So, increasingly, are we.

Vantara: Inside a Billionaire-Backed Bid to Build a Global Wildlife University

The launch comes at a time when conservation challenges are becoming increasingly complex.

A new private university focused on wildlife conservation and veterinary sciences is being positioned as an ambitious attempt to reshape how the world trains the next generation of conservation professionals—backed by one of Asia’s most influential business families.

The institution, Vantara University, has been launched in western India by a wildlife initiative founded by Anant Ambani, part of the Reliance group. Framed as an integrated academic ecosystem, the project reflects a growing trend where private capital is stepping into areas traditionally led by public institutions and global nonprofits.

Vantara officially describes the university as the “world’s first integrated global university” dedicated to wildlife conservation and veterinary sciences. While the scale and integration may be distinctive, similar disciplines are already taught across universities worldwide, often through specialised schools, research centres, and veterinary colleges.

The claim, therefore, rests less on the existence of such education and more on the attempt to consolidate it within a single, purpose-built institutional framework.

A Shift Toward Education-Led Conservation

The launch comes at a time when conservation challenges are becoming increasingly complex. Climate change, habitat fragmentation, and the spread of zoonotic diseases are reshaping ecosystems and exposing the limits of traditional conservation models.

There is a growing recognition that protecting biodiversity will require not just field interventions, but a systemic expansion of expertise—from wildlife veterinarians and epidemiologists to policy specialists and conservation planners.

Vantara University aims to respond to this gap by bringing together disciplines such as wildlife medicine, genetics, behavioural sciences, epidemiology, and conservation policy under one academic structure.

Blending Science, Scale, and Philosophy

The university’s vision combines scientific training with a philosophical framing rooted in compassion and stewardship. Its design draws inspiration from historical centres of learning, while positioning itself as a modern, purpose-led institution.

“The future of conservation will depend on how we prepare minds and institutions to serve life with compassion, knowledge, and skill,” Anant Ambani said in a statement.

“Vantara University is shaped by a deeply personal journey of witnessing animals in distress and recognising the need for greater capability in their care… the university seeks to nurture a new generation committed to protecting every life.”

Global Ambitions, Local Foundations

Although based in India, the project is clearly aimed at a global audience.

The university plans to offer undergraduate, postgraduate, and specialised programmes, supported by research infrastructure and international collaborations. It also emphasises action-oriented learning, linking academic work with real-world conservation practices.

This approach reflects a broader shift in higher education, where institutions are increasingly expected to produce not just knowledge, but deployable expertise.

The Rise of Private Influence in Conservation

The initiative also highlights a larger structural shift: the growing role of private capital in shaping conservation agendas.

Historically, conservation has been driven by governments, multilateral agencies, and non-profit organisations. However, large-scale funding gaps and the urgency of environmental crises are opening the door for philanthropic and corporate actors to play a more prominent role.

This raises both opportunities and questions.

Private initiatives can accelerate innovation and investment, but they also bring concerns around governance, accountability, and long-term alignment with public interest.

Questions of Access and Impact

As with many specialised institutions, accessibility will be a critical test.

While the university has announced scholarships aimed at supporting students from diverse backgrounds, the broader question remains: can such models scale inclusively, particularly for communities most directly affected by environmental change?

The effectiveness of the initiative will also depend on its ability to influence policy, contribute to global research, and produce professionals equipped to address complex ecological challenges.

A Changing Conservation Landscape

The launch of Vantara University signals a deeper transition in how conservation is being imagined.

Increasingly, the field is moving beyond isolated interventions toward integrated systems that connect science, education, and practice. In this context, universities are not just centres of learning—they are becoming critical infrastructure in the fight to preserve biodiversity.

Whether this particular model succeeds will depend on execution, collaboration, and its ability to move beyond vision into measurable impact.

But its emergence underscores a central reality:

The future of conservation may depend as much on classrooms and laboratories as it does on forests and protected areas.

Study Reveals How Ocean Bacteria Drive Plastic Biodegradation

MIT researchers uncover how ocean bacteria collaborate to degrade biodegradable plastics, offering new hope for tackling plastic waste.

Plastic biodegradation is emerging as a critical solution to the global waste crisis, and new research from Massachusetts Institute of Technology offers important insights into how this process actually works in nature.

A new study by researchers at Massachusetts Institute of Technology has shed fresh light on how bacteria in marine environments collaborate to break down biodegradable plastics—offering critical insights into tackling the global plastic waste crisis.

Biodegradable plastics have long been seen as a potential solution to mounting environmental pollution. However, scientists have struggled to determine how long these materials persist in real-world conditions and how microbial communities contribute to their breakdown.

The study, published in Environmental Science and Technology, marks one of the first efforts to identify the specific roles individual bacterial species play in plastic biodegradation.

“Plastic biodegradation is highly dependent on the microbial community where the plastic ends up,” says lead author Marc Foster, a PhD researcher in the MIT-WHOI Joint Program. “It’s also dependent on the chemistry of the plastic itself.”

Unlike earlier studies that focused on single microbes, the MIT team examined how multiple bacterial species work together—a more realistic representation of how plastics degrade in nature.

The researchers studied a widely used biodegradable plastic known as an aromatic aliphatic co-polyester, commonly found in shopping bags, food packaging, and agricultural films.

Samples of this plastic were first exposed to seawater in the Mediterranean, allowing natural bacterial communities to form biofilms on their surface. Scientists then isolated and analysed these microbes in the lab.

Key findings include:

  • One bacterium, Pseudomonas pachastrellae, was able to break down the plastic polymer into smaller chemical components.
  • Other bacterial species were needed to consume those individual chemicals, including terephthalic acid, sebacic acid, and butanediol.
  • No single bacterium could complete the entire degradation process alone.

When researchers combined five complementary bacterial species, they were able to replicate the full degradation process observed in a larger microbial community.

“This complementary function was essential,” Foster explains. “None of the bacteria alone could achieve the same level of degradation as when they worked together.”

Why Plastic Biodegradation Rates Vary

The findings suggest that the speed and efficiency of plastic biodegradation depend on several key factors:

  • Microbial diversity in the environment
  • Chemical composition of the plastic
  • Environmental conditions such as temperature and depth

Notably, the study also found that the same bacterial community could not degrade a different type of plastic, indicating that microbial systems may be highly material-specific.

Implications for Future Plastic Recycling Solutions

The research represents an important step toward developing microbial recycling systems that could convert plastic waste into useful materials.

By understanding how bacteria interact with plastics at a molecular level, scientists could:

  • Design plastics that degrade more predictably
  • Engineer microbial communities for faster plastic breakdown
  • Develop biological recycling technologies

Foster notes that future work will explore how to optimise bacterial combinations and improve enzyme interactions with plastic surfaces.

A Step Forward in Tackling the Plastic Waste Crisis

With more than half of global plastic waste ending up in landfills or the environment, understanding plastic biodegradation is crucial for sustainable material design.

This study highlights a fundamental shift in perspective: plastic degradation is not driven by a single organism, but by complex microbial collaboration.

As research advances, such insights could help bridge the gap between biodegradable materials and real-world environmental outcomes—bringing science closer to solving one of the planet’s most pressing pollution challenges.The study, published in Environmental Science and Technology, marks one of the first efforts to identify the specific roles individual bacterial species play in plastic biodegradation.

Hidden Epidemic: Tuberculosis Spreads Among Kerala’s Captive Elephants

Tuberculosis in Kerala’s captive elephants has become a silent but persistent threat, driven largely by human-to-animal transmission, chronic stress, and systemic failures in veterinary public health. An EdPublica (EP) Investigation reveals how the absence of routine screening, weak governance, and prolonged neglect could turn a preventable disease into a far larger crisis in the years ahead.

By Lakshmi Narayanan | EP Investigation

Tuberculosis is quietly spreading among Kerala’s captive elephants, sustained not by wildlife exposure but by human contact, chronic stress, and systemic neglect. Long treated as a marginal veterinary issue, the disease represents a serious and largely ignored public health and animal welfare crisis—one that experts warn could intensify in the coming years if left unaddressed.

Kerala hosts one of the largest populations of captive Asian elephants in India, housed by temples, private owners, and festival organisers. According to a Forest Department survey concluded in February 2025, the state currently has 389 captive elephants, marking a steady decline from 521 in 2018 and over 700 in 2010, with the majority now owned by private individuals. This sharp reduction over the past decade reflects broader stresses within the captive elephant system, including ageing animals, declining ownership viability, and chronic health concerns.

Within this shrinking population, tuberculosis is neither new nor rare; it is endemic. Historical veterinary records and animal welfare documentation indicate that in earlier years, TB may have contributed to as many as 25 captive elephant deaths annually. Yet in recent times, detailed and transparent reporting on TB-related infections and fatalities has largely disappeared from public view, creating a misleading impression that the risk has diminished when, in reality, surveillance itself has weakened.

This absence of attention does not signal reduced risk. Tuberculosis is a slow, insidious disease that can remain latent or undiagnosed for years. Without mandatory screening or transparent surveillance, infection can circulate undetected within captive elephant populations—allowing animals to suffer prolonged illness and potentially function as silent reservoirs of infection.

The persistence of tuberculosis among captive elephants is not accidental. It is the result of a convergence of vulnerabilities: constant exposure to infected humans, immune suppression driven by captivity-related stress, and systemic failures in veterinary public health governance. Together, these factors have created ideal conditions for a preventable disease to endure—largely unseen, and largely unchallenged.

The Human–Elephant Interface: A Critical Transmission Pathway

The primary route of TB transmission among Kerala’s captive elephants is reverse zoonosis: the spread of infection from humans to animals. The causative agent, Mycobacterium tuberculosis, is a human-adapted pathogen transmitted through respiratory aerosols. In settings where elephants live and work in close proximity to people, this pathway becomes epidemiologically decisive.

Mahouts and handlers represent the most significant source of chronic exposure. Their daily routines—feeding, bathing, training, and transporting elephants—require prolonged, close physical contact. If a handler carries an active or latent TB infection, the opportunity for transmission to the animal is constant and cumulative.

In addition to handlers, the general public constitutes a secondary but important exposure source. Kerala’s festival culture routinely places elephants amid dense crowds, often for extended periods. These gatherings create intermittent but high-volume opportunities for transmission from undiagnosed or untreated individuals within the broader population. Together, these human reservoirs ensure that captive elephants are rarely insulated from the pathogen. Yet exposure alone does not fully explain disease persistence. The risk of infection is significantly magnified by conditions that undermine the elephants’ immune defenses.

“Tuberculosis in captive elephants is a severe and often underestimated disease. What is seen during post-mortem examinations is extensive, chronic organ damage that reflects prolonged suffering rather than sudden illness. These findings are consistent with long-term exposure to Mycobacterium tuberculosis and delayed detection, Dr. Arun Vishvanathan, a veterinary expert based in Kerala’s Palakkad district, tells EdPublica.

“From a medical and public health perspective, this condition is particularly concerning because it is largely driven by human-to-animal transmission. Elephants living in close, continuous contact with people—especially under stressful captive conditions—experience immune suppression, which allows the infection to progress unchecked. This is not an unavoidable disease; it is a preventable one. Without routine screening of both handlers and elephants, early diagnosis, and strict biosecurity measures, such cases will continue to occur, resulting in needless animal suffering and ongoing public health risk,” Dr. Arun Vishvanathan adds.

Stress, Captivity, and Immune Compromise

Captive environments impose profound physiological and psychological stress on elephants, a species evolved for expansive movement, complex social structures, and environmental autonomy. Confinement to restricted spaces, prolonged chaining, limited exercise, and forced participation in noisy, crowded festivals all contribute to chronic stress.

Scientific evidence across species demonstrates that sustained stress suppresses immune function. In elephants, this immunosuppression reduces resistance to opportunistic infections such as TB and increases the likelihood that latent infections will progress to active disease.

Crowding further compounds the problem. Elephants housed in close quarters or transported frequently between venues are exposed not only to more humans but also to environments conducive to airborne disease transmission. In these conditions, respiratory pathogens can spread efficiently, especially when animals are already physiologically compromised.

A shrinking captive elephant population and persistent health risks highlight the urgent need for coordinated veterinary and public health oversight.

”Tuberculosis in Kerala’s captive elephants spreads primarily through close, repeated contact with infected humans, and is sustained by conditions that weaken the animals’ natural defenses. Unlike many wildlife diseases, this is not an infection originating in forests—it is largely a human-driven disease cycle. Mahouts and handlers are the most significant transmission source. Daily activities such as feeding, bathing, chaining, and transport require close physical proximity, often for hours at a time. If a handler has active or undiagnosed TB, the elephant is repeatedly exposed to infectious aerosols,” says Manuprasad, an elephant welfare worker from Thrissur.

Festival crowds and tourists create additional exposure. During temple festivals and public events, elephants are surrounded by dense crowds, sometimes for entire days. In these settings, even brief exposure to multiple infected individuals can result in infection.

Systemic Gaps in Veterinary Public Health

Perhaps the most critical vulnerability lies not in biology but in governance. Kerala lacks a standardized, mandatory TB screening programme for captive elephants. As a result, infected animals—many of them asymptomatic—remain undiagnosed for years. This failure in routine surveillance effectively blinds any meaningful public health response and allows elephants to function as silent reservoirs of infection.

Experts warn that tuberculosis in Kerala’s captive elephants could expand if mandatory screening and biosecurity measures are not urgently implemented.

Nutritional inadequacy is another systemic issue. Economic pressures within the temple and festival ecosystem often translate into suboptimal feeding regimes. Poor nutrition weakens immune responses, lowering the infectious dose required for TB to establish and spread.

Compounding these challenges is a widespread lack of awareness among elephant owners and handlers regarding TB transmission and prevention. Clear, enforceable biosecurity protocols—covering quarantine, treatment, and movement restrictions for TB-positive animals—are largely absent or inconsistently applied. Without such measures, even identified cases pose an ongoing risk to other elephants and to humans.

”As an animal rights and welfare activist, I have personally witnessed the post-mortem of an elephant affected by tuberculosis, and it was deeply distressing. The extent of internal damage revealed the severe and prolonged suffering this animal endured—far beyond what most people realize. Seeing such devastation in an animal of immense strength and dignity is heartbreaking,” explains Ambili Purackal, founder of DAYA, a Kerala-based NGO known for its proactive role in the state’s animal rights movement.

What makes this suffering even harder to accept is that it is largely the result of human exposure. Elephants do not face tuberculosis at these levels in the wild; they contract it through forced, prolonged contact with humans under stressful captive conditions that weaken their immunity. This is not just a veterinary concern but a moral one. These elephants are silent victims of preventable disease, and their suffering is a consequence of human neglect and systemic failure,” Ambili Purackal says.

Secondary and Less-Documented Risks

While human-to-elephant transmission remains the dominant concern, other pathways cannot be entirely dismissed. Interactions with domestic livestock or wildlife in shared environments may contribute to transmission chains, though this remains poorly documented in the Indian context. These ancillary risks further underscore the need for comprehensive epidemiological research.

A Convergence of Vulnerabilities

Taken together, the vulnerabilities facing Kerala’s captive elephants form a self-reinforcing cycle. Constant exposure to a human TB reservoir, chronic immune compromise driven by captivity-related stress and poor nutrition, and systemic failures in disease detection and control create ideal conditions for TB persistence.

Breaking this cycle will require a multi-layered public health approach—one that integrates routine screening, improved nutrition, handler health monitoring, and enforceable management protocols. Without such intervention, tuberculosis will remain a silent epidemic, exacting a slow but devastating toll on one of Kerala’s most culturally significant animal populations.

Silence, in this case, is not neutrality—it is risk.

What Needs to Change

Addressing tuberculosis among Kerala’s captive elephants requires coordinated action across animal welfare, public health, and governance. Experts and welfare workers interviewed by EdPublica point to the following urgent priorities:

1. Mandatory TB Screening

·       Routine, standardised tuberculosis testing for all captive elephants

·       Regular TB screening for mahouts, handlers, and caretakers

·       Immediate isolation and treatment protocols for positive cases

2. Handler Health Monitoring

·       Integration of mahout health checks into public TB control programmes

·       Confidential diagnosis and treatment access to reduce stigma and underreporting

3. Improved Living Conditions

·       Reduced chaining and confinement

·       Adequate daily exercise and social interaction

·       Limits on festival exposure, crowd density, and noise-related stress

4. Nutritional Standards

·       Enforced minimum nutrition guidelines

·       Regular veterinary audits to ensure immune-supportive diets

5. Biosecurity and Movement Controls

·       Quarantine protocols for newly acquired or transferred elephants

·       Restrictions on inter-district or inter-state movement of TB-positive animals

6. Transparent Reporting and Oversight

·       Publicly accessible data on TB cases and outcomes

·       Independent audits of temple and private elephant management practices

7. Interdepartmental Coordination

·       Formal collaboration between forest, animal husbandry, and public health departments

·       Recognition of TB in captive elephants as a One Health issue—linking human, animal, and environmental health
