The sicker you are, the worse your neighborhood's plumbing.
In five urban settlements of Thiruvananthapuram, a research team has done what poverty itself has long communicated without words: mapped the precise geography where broken infrastructure becomes broken bodies. A survey of 3,341 residents by the Gulati Institute of Finance and Taxation found respiratory infections, hypertension, and vector-borne diseases flourishing in the same spaces where drains run open, garbage accumulates uncollected, and nearly a third of children grow stunted from malnutrition. The study does not reveal a mystery so much as it renders visible a moral condition — that the distance between sickness and health in this city is often measured not in biology, but in plumbing.
- Nearly one in five residents suffers from respiratory infections, and the poorest households are almost twice as likely to report illness — a statistical confirmation of what open drains and overcrowded rooms have always quietly declared.
- Children are bearing a disproportionate share of the burden: 32% are stunted, 28% underweight, and 7% have missed critical immunizations, while gastrointestinal and respiratory illnesses cycle through their bodies with seasonal regularity.
- When the monsoon arrives, waterborne and vector-borne diseases spike sharply across settlements where garbage collection reaches as few as 11% of households and piped water does not flow daily for up to a third of residents.
- Thirty-eight percent of families have turned away from public health services entirely — citing distance, cost, and distrust — seeking private or informal care instead, a quiet vote of no confidence in the systems meant to protect them.
- Researchers are calling for deliberate investment in safe water, sanitation, drainage, and waste collection, framing these not as amenities but as the foundational conditions without which disease reduction is structurally impossible.
In five urban colonies across Thiruvananthapuram — Barton Hill, Chirakulam, Kanjirampara Harijan Colony, Rajajinagar, and Karimadam — researchers from the Gulati Institute of Finance and Taxation surveyed 3,341 people across 716 households and found illness patterns that followed the contours of infrastructure almost exactly. Respiratory infections affected nearly one in five residents. Hypertension, vector-borne diseases, gastrointestinal illness, diabetes, and mental health conditions followed in sequence. The physical environment surrounding these families told the same story: overcrowded homes, open drains at the doorstep, garbage left to accumulate in streets where children played, and water that arrived unreliably even where pipes existed.
The numbers were unsparing. Between 36 and 54 percent of households had indoor toilets; the rest depended on shared facilities or open defecation. Municipal garbage collection reached only 11 to 21 percent of households. When the monsoon came, waterborne and vector-borne diseases rose sharply in settlements already living at the edge of sanitary failure.
Illness distributed itself across age groups with grim logic. Children suffered most from respiratory and gastrointestinal infections. Adults accumulated hypertension and diabetes. The elderly carried multiple chronic conditions at once. Malnutrition ran through it all — 32 percent of children stunted, 28 percent underweight — while adults in the same households were increasingly overweight, their diets built almost entirely on carbohydrate staples with little fresh produce in reach.
The poorest households were nearly twice as likely to report illness as those with higher incomes. Thirty-eight percent of families had stopped using public health services altogether, turning to private clinics or informal providers out of frustration with distance, cost, and quality. Seven percent of children had missed recommended immunizations.
The researchers concluded plainly: the disease burden in these colonies would not ease without deliberate investment in the infrastructure that wealthier neighborhoods already possess — safe water, functioning sanitation, drainage that works, waste collection that reaches every household, and public health services close enough to trust. The data had made the problem legible. What remained was whether the city would choose to act on it.
In five cramped urban colonies scattered across Thiruvananthapuram—Barton Hill, Chirakulam, Kanjirampara Harijan Colony, Rajajinagar, and Karimadam—a pattern of illness has taken hold that tracks almost perfectly with the infrastructure that surrounds it. Researchers from the Gulati Institute of Finance and Taxation surveyed 3,341 people living in 716 households across these settlements and found something unsurprising to anyone who has lived in poverty, but worth documenting anyway: the sicker you are, the worse your neighborhood's plumbing.
Respiratory infections topped the list of complaints, affecting nearly one in five residents. Hypertension followed close behind, then vector-borne diseases—dengue, malaria, and their cousins. Gastrointestinal illnesses, musculoskeletal disorders, diabetes, skin diseases, and mental health conditions rounded out the burden. The study, conducted by researchers Merlin Premala and Krishnakumari K, mapped these illnesses against the physical reality of where people lived: overcrowded homes, open drains running past doorways, garbage piling up in streets, water that arrived sporadically if at all.
The numbers tell a story of infrastructure failure. Sixty-two percent of households were overcrowded. Between 36 and 54 percent had toilets inside their homes—meaning the rest relied on shared facilities or open defecation. Between 63 and 85 percent of residents lived alongside open drains. Garbage collection by the municipal authority reached only 11 to 21 percent of households, leaving waste to accumulate in neighborhoods where children played and families cooked. Piped water existed in most homes, but the water itself arrived daily in only 65 to 88 percent of them. When the monsoon came, waterborne and vector-borne diseases spiked sharply.
The illness patterns shifted across age groups in ways that made biological sense. Children bore the heaviest burden of respiratory and gastrointestinal infections. Adults increasingly reported hypertension and diabetes—the slow-moving diseases of stress and poor diet. The elderly carried multiple chronic conditions simultaneously. Women reported higher rates of hypertension and musculoskeletal pain. Men reported more heart disease and diabetes. Malnutrition threaded through it all: 32 percent of children were stunted, 28 percent underweight. Adults swung the other direction, with 21 percent overweight or obese, their diets built almost entirely on carbohydrate-heavy staples with almost no fresh produce.
The statistical relationship between poverty and illness was stark. People living in the poorest households were nearly twice as likely to report being sick compared to those with higher incomes. Those in physically degraded environments faced similar multiplied risk. Seven percent of children had missed their recommended immunizations. Thirty-eight percent of families bypassed public health services entirely, turning instead to private clinics or informal providers—citing distance, cost, and doubts about quality.
The researchers' conclusion was direct: the disease burden in these five colonies would not ease without deliberate investment in the basic infrastructure that wealthier neighborhoods take for granted. Safe drinking water systems. Proper sanitation. Drainage that actually drains. Solid waste collection that actually collects. Stronger public health services within reach. Community participation in solutions. None of this was mysterious or complicated. The poor were sick because the systems meant to keep them well had never been built, or had been allowed to fail. The question now was whether the city would act on what the data made plain.

Poor living conditions increased the likelihood of falling ill; people with lower standard of living were nearly twice as likely to suffer from morbidity— Gulati Institute of Finance and Taxation study
La Conversación del Hearth Otra perspectiva de la historia
Why does the study separate out respiratory infections as the most common problem? That seems almost expected in a crowded, poorly ventilated place.
It's expected, yes—but the study quantifies it. Nearly one in five people. That's not a background condition; that's a dominant feature of life in these colonies. It's what people are living with every day.
And the monsoon spike in waterborne diseases—that's seasonal, so it should resolve on its own?
It resolves until the next monsoon. But the underlying problem doesn't go away. Open drains, stagnant water, no waste collection—those are permanent. The monsoon just makes them lethal.
The malnutrition numbers are striking. Thirty-two percent of children stunted. How does that connect to the disease patterns?
A stunted child is already immunologically compromised. They're more vulnerable to respiratory infections, gastrointestinal illnesses, everything else. Malnutrition and disease feed each other. You can't separate them.
What about the 38 percent using private providers instead of public health services? That seems like a choice.
It's a choice made under constraint. Distance, cost, distrust. If the public system were accessible and trustworthy, people wouldn't be paying out of pocket for informal care. That's not preference; that's desperation.
So the solution is just infrastructure—water, sanitation, waste collection?
That's the foundation. But it also requires the public health system to actually function, to be present in these neighborhoods, to be worth using. Infrastructure alone won't work if people don't trust what comes next.
