Epidemiological transmission periods: 1st neolithic revolution, sedentary communities, irrigation, domestication, 2nd 19th/20th century science and technology, pasteur, koch, Fleming, antibiotics: 3rd drug resistance, insecticide resistance, new pathogens. Underlying causes of emerging disease phenomena: artifacts of detection and naming, changes in human activity, domestication of animals, seeking new habitats, evolution and ecological change, climate, pathogenicity. Emerging diseases: resurgence or recurrence of old diseases (via mutation or exposure, diseases of animals that jump species and become new diseases of humans (zoonosis) Syndromes previously known but not ascribed to a particular cause.
