Epidemiological Transition

Epidemiological transition describes the shift in disease patterns within a population over time. As societies develop, infectious diseases like influenza and tuberculosis become less common, replaced by chronic, non-communicable diseases such as heart disease, cancer, and diabetes. This transition reflects improvements in healthcare, sanitation, and living standards, leading to longer life spans. It highlights how advances in managing infections change health challenges, emphasizing the need for healthcare systems to adapt focus from controlling infectious threats to preventing and treating chronic illnesses.
