A major report published in The Lancet on 10 October 2026 has identified 17 catastrophic threats to human health that could shape the rest of this century. The Lancet Commission on 21st Century Global Threats to Health was launched at the World Health Summit in Berlin and is co-chaired by Professor Christopher Murray, director of the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, and Dr Natalia Kanem, former head of the UN Population Fund.
The 17 threats
The commission reviewed hundreds of possible risks across 204 countries and territories before choosing 17. Two were placed in a special category because they could threaten human survival itself:
- Malicious use of artificial intelligence
- Nuclear conflict
The other 15 catastrophic threats are:
- Obesity
- High blood pressure
- Smoking
- High alcohol use
- Air pollution
- Climate change
- Antimicrobial resistance (drug-resistant infections)
- Naturally occurring pandemics
- Childhood malnutrition
- Poor mental health
- Unhealthy ageing
- Low educational attainment
- Income inequality
- Conventional conflict
- Declining development assistance for health
Obesity leads the burden
The commission measured threats in DALYs (disability-adjusted life years), a measure of years of healthy life lost. Its key estimates of the burden that could be avoided by 2100 include:
- Obesity: about 23.1 billion DALYs, the largest of all
- Low educational attainment: about 16.1 billion DALYs
- Income inequality: about 13.8 billion DALYs, which the authors compare to 25 COVID-19 pandemics
- Malicious AI: about 10.4 billion DALYs could be averted with action
- Nuclear conflict: preventing it could avert around 133 million deaths
The authors stress that the list is not a fixed ranking and should be reassessed as risks change.
What it means for India
Coverage in Indian media has pointed out that India faces every one of the 17 threats. Many are already familiar: rising obesity and diabetes, high blood pressure, toxic winter air in north Indian cities, drug-resistant infections linked to antibiotic overuse, persistent child malnutrition alongside adult obesity, and the health effects of extreme heat.
The commission's three priorities
- Build readiness: health systems with stable funding that focus on prevention and preparedness, especially for poorer communities.
- Back breakthroughs: invest in new vaccines, antibiotics, obesity treatments and climate technologies, with fair access.
- Track threats: regular independent monitoring through a proposed "Lancet Monitor" of global threats.
What you can do personally
- Keep a healthy weight through balanced meals and regular activity.
- Check your blood pressure at least once a year.
- Avoid tobacco and limit alcohol.
- Take antibiotics only when prescribed and complete the course.
- Protect yourself on high-pollution days by checking the AQI and limiting outdoor exercise.
- Look after your mental health and seek help when needed.
