India faces shifting disease burden from infections to lifestyle illnesses

India is experiencing a significant shift in its national disease burden, moving from a primary focus on infectious diseases and malnutrition toward a rise in non-communicable diseases (NCDs). Since independence in 1947, improvements in sanitation, immunization, and nutrition have reduced the impact of illnesses such as tuberculosis, malaria, and diarrhoeal diseases.

However, economic development, urbanization, and increased life expectancy have introduced a “double burden” of disease. India now faces a simultaneous challenge of managing both communicable diseases and lifestyle-related chronic conditions. The rise of NCDs—including diabetes, heart disease, cancer, stroke, and obesity—is driven by risk factors such as tobacco use, unhealthy diets, physical inactivity, and high blood pressure.
