10.4 Public health and sanitation

Public health and sanitation emerged as crucial responses to urbanization and industrialization during the Modern Period. Advancements in scientific understanding, particularly germ theory, revolutionized disease prevention and treatment approaches, shifting focus from miasma to microorganisms.

Urban sanitation reforms addressed pressing health issues in growing cities, improving infrastructure and living conditions. These reforms, along with the development of epidemiology and disease control measures, laid the groundwork for modern public health systems and significantly reduced mortality rates.
