The Epidemiological Transition in India
As the recent “Survey on Household Social Consumption: Health” by the National Statistics Office reveals, India is witnessing a major epidemiological transition, wherein the disease burden is gradually shifting from communicable diseases to non-communicable diseases (NCDs). This transition has significant implications for public health policy, economic productivity, and healthcare financing.
Nature of the Transition
- India’s disease profile has shifted from Communicable, Maternal, Neonatal and Nutritional Diseases (CMNNDs) towards Non-Communicable Diseases (NCDs) and injuries.
- NCDs account for nearly 60-65% of total deaths, with cardiovascular diseases, diabetes, cancer, and chronic respiratory disorders emerging as major causes of mortality.
- Rising life expectancy and an ageing population have accelerated the burden of chronic diseases.
Key Drivers and Challenges
- Rapid urbanisation, sedentary lifestyles, unhealthy diets, pollution, tobacco use, and stress are major contributors to rising NCD prevalence.
- Simultaneously, diseases such as tuberculosis, dengue, and malaria persist, creating a double burden of disease.
- Regional disparities in healthcare infrastructure and rising out-of-pocket expenditure further aggravate health inequities.
What Needs to Be Done?
India’s epidemiological transition reflects both progress and emerging structural health challenges. A balanced strategy combining disease prevention, healthcare accessibility, and strengthened public health infrastructure is essential for achieving sustainable and equitable health outcomes.
