"The Epidemiological Transition"

The Epidemiological Transition is a concept that describes how the patterns of health and disease in populations change over time. It typically occurs as societies develop economically and socially. Initially, countries may face high rates of infectious diseases and mortality. As they progress, improvements in healthcare, sanitation, and nutrition lead to a decline in these diseases, while chronic illnesses like heart disease and diabetes become more prevalent. Understanding this transition helps public health officials address current health challenges and anticipate future trends in different populations.
