Health Threats: Lancet Warns India Faces All 17

The Lancet Commission on 21st Century Global Threats to Health has issued a stark warning: India faces all 17 health threats that could cause catastrophic losses of healthy life over the coming decades. The Commission was launched at the World Health Summit 2026 in Berlin and assessed long-term risks across 204 countries and territories, projecting health losses through 2100. "Humanity still has the agency to act," said co-chair Professor Christopher JL Murray, director of the Institute for Health Metrics and Evaluation at the University of Washington.

Health Threats Ranked by Projected Burden

Obesity emerged as the single largest of the 17 health threats, with about 23.1 billion avoidable disability-adjusted life years (DALYs) projected by 2100. DALYs measure healthy years of life lost to illness, disability or premature death, and the Commission classified a threat as "catastrophic" if it could account for at least 1 billion DALYs by 2100. Alongside obesity, the list of health threats includes low educational attainment, income inequality, malicious use of AI, nuclear conflict, poor mental health, unhealthy ageing, smoking, conventional conflict, high blood pressure, antimicrobial resistance (AMR), high alcohol use, pandemics, climate change, air pollution, collapse of development assistance for health and childhood malnutrition. Nuclear conflict and the malicious use of AI were flagged as potentially extinction-level dangers to global health.

The Price of Warming and Lost Aid

Two of the health threats are measured in stark avoided-cost figures. Limiting global warming to around 1.8°C rather than 4.4°C could prevent some 1.89 billion years of healthy life lost by 2100, the Lancet Commission report says. Meanwhile the collapse of development assistance for health could cost up to 1.5 billion DALYs, with around 70 per cent of that toll falling on sub-Saharan Africa — a warning for global health equity that India health policy planners cannot ignore. Pandemics, antimicrobial resistance, smoking, alcohol use and high blood pressure add to the mounting pressure on health systems already stretched by chronic disease. The Commission also warns that conventional conflict and pandemics could amplify every other threat, turning local crises into cross-border emergencies. It calls on governments to treat prevention as core infrastructure rather than an optional expense.

What India Health Policy Must Do as Health Threats Mount

For India, the assessment cuts across the whole spectrum of public health. Air pollution, childhood malnutrition, obesity, hypertension and poor mental health need sustained attention in the country, according to the Commission's findings. Climate change could worsen each of these through extreme heat, disruption to food supplies and interruptions to health services. The report urges India to integrate long-term forecasting into health planning and to take a leading role in global negotiations on AI safety and pandemic preparedness. With India health policy now confronting these pressures alongside an ageing population, the Commission argues that early investment beats late emergency response.

Three Priorities to Counter the Health Threats

The Lancet Commission set out three priorities for tackling the 17 health threats: build preparedness for known and unknown risks, invest in scientific breakthroughs, and track and monitor emerging threats before they escalate. Co-chairs Murray and Natalia Kanem, the former executive director of the UN Population Fund, argue that the century's biggest risks are foreseeable — and therefore preventable. For global health, the message is that catastrophe is a policy choice. "Humanity still has the agency to act," Murray said, insisting the projections are a call to arms, not a verdict.
