Timeline of global health


This page is a timeline of global health, including major conferences, interventions, cures, and crises.

During this pre-WWII era, there are three big trends that operate separately, but sometimes affect each other in development and outcomes.

First, a trend of urbanization (fueled by the Industrial Revolution) as well as greater global trade and migration leads to new challenges, including those in urban sanitation and infectious diseases/pandemics. Six global cholera pandemics happen in this period because of increased commerce and migration.

Second, there is a lot of development on the underlying theory of disease, advancements in vaccine and antibiotic development, and a variety of experimental large-scale eradication and control programs. One big example: the germ theory of diseases begins to become accepted and popularized starting around 1850. Another big example is the development of the smallpox vaccine by Edward Jenner in 1796. Systematic eradication and control efforts include the Rockefeller Sanitary Commission and efforts to eradicate smallpox. Antitoxins and vaccines for numerous diseases including cholera and tuberculosis are developed during this period, building on a trend of greater understanding of and control over microorganisms.

A third theme during this era is the formation of various preliminary international alliances and conferences, including the International Sanitary Conferences, Pan American Health Organization, Office International d'Hygiène Publique, and the League of Nations Health Committee. This is closely intertwined with the other two trends. For instance, the cholera pandemics mentioned above, as well as the growing scientific understanding of the germ theory of disease, are both key impetuses for the International Sanitary Conferences.

Following the end of World War II, the first batch of big organizations, both international and national (with international cooperation), including the United Nations and World Health Organization (WHO), form. Beginning with the United Nations Relief and Rehabilitation Administration for relief of victims of war in 1943, there is a big push to begin creating large scale health initiatives, non-governmental organizations, and worldwide global health programs by the United Nations to improve quality of life around the world. UNICEF, the World Health Organization, as well as the UNRRA are all part of United Nations efforts to benefit global health beginning with developing countries. These various programs aim to aid in economic endeavors by providing loans, direct disease prevention programs, health education, etc.
