Global patterns of health, mortality and morbidity; economic and social development and the epidemiological transition
Countries at different stages of development have very different patterns of disease and death. As a country develops, its main causes of death shift from infectious diseases to long-term conditions like heart disease.
Real World
South Korea has moved firmly into Stage 4 of the epidemiological transition: deaths from communicable diseases like tuberculosis have plummeted since the 1960s, while heart disease and cancer now account for over 50% of all mortality.
Exam Focus
Define epidemiological transition precisely in introductions — markers reward accurate use of terms like 'communicable', 'non-communicable', 'morbidity', and 'mortality'.
