History of Phthisiology and Epidemiology

Abstract

Phthisiology, the specialized branch of medicine dealing with tuberculosis (TB), and epidemiology, the study of disease patterns in populations, have evolved in parallel over centuries. Tuberculosis, historically known as “phthisis” or “consumption,” has been one of the most persistent and deadly infectious diseases in human history. Its impact has extended beyond medicine into social, economic, and cultural domains. This article provides a comprehensive and expanded exploration of the historical development of phthisiology and epidemiology, highlighting major milestones, scientific breakthroughs, and public health strategies that shaped modern understanding and control of TB.
