Neanderthal medicine
Technically advanced pro-social healthcare. Evidence from skeletal remains shows cared-for injuries extending over months, indicating sophisticated medical knowledge and social support structures without written records.

Public health systems
Hippocratic-style medical records; hospitals; vaccinations (variolation); social safetynet. State-funded responses to disease emerge, particularly in Song Dynasty China with 293 documented epidemic responses combining hospitals, food support, and mobile care.
Scientific medicine
Germ theory, tabular data, environmental interventions. John Snow's cholera maps demonstrate spatial epidemiology. James Lind's controlled scurvy trials establish evidence-based medicine. Standardised death certificates enable statistical calculation.
Epidemiology controls diseases
Global mass vaccinations; antibiotics at scale; millions of lives saved annually following control of smallpox, malaria, polio, TB. For the first time, entire urban populations made safe from deadly pathogens through coordinated population-scale intervention.
Actuarial orientation & statistics
Risk factors; surveillance; child vaccinations; Control of measles, rubella, YFV. The field shifts from crisis response to predictive prevention, using statistical models to identify vulnerable populations before outbreaks occur.
Modern tools in use
Computers; molecular medicine; SEIR models; large cohorts; eradication of smallpox; eliminations of malaria, polio, measles. Anderson & May (1991) establishes R₀ as the fundamental metric for infectious disease dynamics.
Population-scale policy success for complex problems
Stochastic models; evidence-based medicine; epidemic simulation possible; new tools gave solutions for difficult epidemics: AIDS, SIDS, Ebola and Hep. C. Modelling becomes intimate with policy advice, calculating intervention impacts before implementation.
Limits reached of narrow technical approaches
Infectious Diseases of Humans (Anderson & May 1991) becomes the mathematics driving policy advice; new mechanistic statistical modelling, big genetic and spatial datasets, fast computers. Yet models still exclude environment, vector ecology; diet and too much more. Progress stalls.

The New Epidemiology
Since about 2010, for the first time in history, technical ability and political motivation emerged to bring together dozens of scientific and medical fields. Their combined knowledge is used to calculate health results across humans, animals and ecology, in the acceleration project to get the derailed world health development goals back on track. The Global One Health Initiative tracks progress.
The US reneged in 2025, destroying surveillance programmes and exiting multilateral agreements. The world is responding, committing again to One Health. This is the new epidemiology in 2026.
