Ravikant (name changed) had farmed the same black soil fields in the Gadag district all his life. At 60, he felt fine. He had no chest pain, no fever, and no significant loss of weight. When he occasionally coughed, he put it down to old age, nothing more. He had never been to a city hospital. He did not think he needed to.
Then one morning, a health screening camp arrived in his village, run by a team carrying what looked like a small briefcase.
Mobile screening teams carry the AffEx kit to village camps and local health facilities.
He walked in casually. There were no obvious symptoms that brought him there. No alarm, no crisis. Within minutes, a smartphone-based respiratory screening tool analysed his cough pattern using an AI model. It flagged him as high-risk. The health worker referred him for further testing. Weeks later, he was diagnosed with tuberculosis at a stage where treatment could still make a full difference.
“I had no idea,” he said later. “I thought I was just getting old. There was nothing that told me something was wrong.”
A health worker records basic screening details during a community health camp.
That is what makes the story both remarkable and sobering: Ravikant was not a man in denial. He genuinely had no symptoms. The disease was silently progressing inside him, undetected, as it does in millions of people across rural India every single day.
The illness you don’t know you have
Ravikant’s story is not unusual. It is, in fact, devastatingly common.
Across India’s rural and underserved communities, millions of people are living with conditions they cannot name. Hypertension quietly elevates the risk of a stroke that arrives without warning. Diabetes builds for years before peripheral nerves fail. Anaemia drains women and children of energy so gradually that exhaustion begins to feel normal. Tuberculosis spreads in bodies whose owners are still working the fields, cooking the meals, and going about their days.
Field teams use portable devices to run health checks in community settings.
The problem is not just disease. It is the gap between when a disease begins and when it is found. In cities with routine check-ups, private clinics, and easy access to diagnostics, that gap can be weeks. In rural India, it is often months.
“By the time many patients reach us in tertiary care, the disease has already progressed significantly,” says a physician involved in rural health outreach in Karnataka. “If we could catch these conditions a few months earlier, the outcomes — and the costs — would be completely different.”
A kit that screens 20+ parameters in under 10 minutes
The portable kit that reached Ravikant’s village is called AffEx — a platform developed under the Anjani Mashelkar Foundation (AMF), founded in 2011 by Padma Vibhushan Dr R A Mashelkar, one of India’s most celebrated scientists.
The AffEx kit brings multiple medical-grade screening tools into one portable setup.
Dr Mashelkar, former Director General of CSIR and a Fellow of the Royal Society, built AMF on a single driving idea: that true inclusive innovation must bring access equality despite income inequality. He calls it “affordable excellence.” Technology that is not watered-down or a lesser version designed for the poor, but genuinely high-quality and made affordable by design.
AffEx is that philosophy in a kit.
India’s first completely medical-grade, point-of-care, fully digital early detection and monitoring platform packs an extraordinary range of tools into something a health worker can carry on her shoulders. The kit includes a non-invasive haemoglobin testing device (no needle, no blood), a digital blood pressure monitor, a smartphone-based respiratory health screening tool that uses a cough as a biomarker for TB, COPD, and asthma, a glucometer, a smart BMI machine, a 12-lead digital ECG, and an AI-enabled digital stethoscope that listens to the heart sounds and flags cardiac murmurs automatically.
The portable kit includes digital devices for vitals and respiratory screening.
The whole assessment — covering 20+ parameters — takes less than ten minutes per person. Every result is instantly digitised, stored, and accessible through a clinical dashboard that tracks individuals over time. For a community health worker like Prabha, it means the difference between noting a concern and actually catching it.
The day Prabha heard a heart
Prabha Kulkarni is an ASHA worker in Umari village, Karanja, in Maharashtra’s Vidarbha region, one of India’s most economically distressed agricultural belts. For years, her toolkit had been simple: a weighing scale, a mid-upper arm circumference tape, a register book, and her feet.
She walked her rounds every day, tracking pregnancies, nudging families toward vaccination, following up on malnutrition. She did it without complaint and without much recognition. But she had always felt the edges of what she could do. She could notice, she could refer. She could not diagnose.
Frontline workers learn how to handle and interpret readings from AffEx devices.
Then, during an AffEx training session, a trainer placed a digital stethoscope in her hands.
It was not an ordinary stethoscope. The AI-enabled device captures and analyses heart sounds in real time. Place it on a patient’s chest, and within seconds the platform tells you whether it has detected a cardiac murmur, an early warning sign that the heart is not working as it should.
An ASHA worker is trained to use digital screening equipment during field deployment.
Prabha pressed the device to a patient’s chest. She listened. Then she looked at the screen.
“Pahilyandach hrudayache thoke itke spasht aiku aale mala. Vatla kharch kunaacha jeev vachavtey mi,” she said softly (For the first time, I could hear the heartbeat so clearly. I thought I was truly saving someone’s life today.)
Community health workers attend training before using the kit in screening camps.
For Prabha, the moment was not just clinical. It was personal. She had spent years as a frontline worker, respected in her community but often invisible to the healthcare system. Now she was holding AI in her hands. She was the one detecting what a heart might be hiding.
The hardest problem: what happens after the camp
India is not short of health camps. Many NGOs, government programmes, and CSR initiatives run them regularly. But those who work in rural healthcare will tell you something sobering: a camp that finds a problem and then walks away may do as much harm as good.
A person told they are high-risk for hypertension needs follow-up counselling, possibly medication and certainly monitoring. But without a system to track them, they go home, worry for a few days, and then return to life. Six months later, nothing has changed. Or everything has.
Patients wait as health workers conduct screening at a local outreach site.
AffEx was built with this gap in mind. Once someone is flagged, the platform stores their digital health record, enables referral coordination, connects them to teleconsultation, and keeps them trackable for follow-up. The tool is not a one-day intervention. It is the beginning of a thread that stays connected.
Health workers demonstrate AffEx devices during a service delivery session in Goa.
“The screening is just the first step,” says a frontline health coordinator who has deployed AffEx in tribal districts of Maharashtra. “What matters is whether the person gets treated. The platform keeps us connected to them. We know who was flagged, who was referred, who followed up and who didn’t. That’s what changes outcomes.”
50,000 people and a first mile that could change everything
AffEx is currently operating across six states and has screened more than 50,000 individuals through community outreach programmes, rural screening initiatives, tribal health drives, and institutional collaborations.
But the number that matters most is not 50,000. It is the number of people who, like Ravikant, would not have known what was coming — and now do.
Frontline workers use digital devices to record vitals during rural screening.
For most Indians, the first point of healthcare contact is not an AIIMS or a corporate hospital. It is a primary health centre. It is a mobile van. It is an ASHA worker like Prabha, walking from door to door with a notebook and a blood pressure cuff.
If those first-mile workers can be equipped with tools like AffEx, tools that are genuinely medical-grade, genuinely affordable, and genuinely simple enough for a trained community worker to use, then the entire architecture of early detection changes.
A frontline worker empowered by AI
Ravikant completed his TB treatment. He still farms the same black soil in Gadag. But he goes for check-ups now. He tells his neighbours about the camp, about the little briefcase, about what it found in a cough he had learned to ignore.
And in Umari, Prabha still walks her rounds every day. But now she carries something new in her kit. When she places the digital stethoscope against a chest and watches the screen, she feels something she had not felt before in twenty years of community work.
ASHA workers take part in a training session on using the portable health kit.
“Now when I go to a house, they trust me differently,” she says. “Before, I could only tell them to go to the doctor. Now I can show them what is happening in their own body. That changes everything.”
That feeling of a frontline worker empowered, of a patient found before the worst arrives, of a system that reaches people instead of waiting for them is what Dr Mashelkar’s vision of “affordable excellence” looks like in practice.
A screening team interacts with residents during a community outreach session.
The technology is impressive. But the real story is simpler and older than any device.
It is the story of what happens when someone decides that people in a village in Vidarbha deserve the same quality of early detection as someone in a city clinic. And then builds it.
AffEx Healthcare is an initiative of the Anjani Mashelkar Foundation, which works to bring high-technology, ultra-affordable healthcare innovation to underserved communities across India.
