The Chronic Disease Landscape

This lesson introduces the chronic disease landscape: what chronic diseases are, how they affect people and health systems, and why prevention is one of the most powerful health strategies available.

Professor Amit Kumar explains the scale of the burden, the most common preventable conditions, and the major trends shaping risk over time. The lesson focuses on understanding the problem clearly so learners can see where prevention fits before moving into risk factors, habits, screening, and practical action later in the course.
