5.  In the past, main causes of death were due to a single pathogen (disease causing microorganism or related substance)  Epidemiologists had the challenge of isolating a single bacteria, virus, or parasite

6.  The discipline of epidemiology underwent dramatic changes in the first half of the 20th century.  A new kind of epidemiology came into being as a discipline in the decades following the Second World War variously referred to as “modern” or “risk factor” epidemiology (Parascandola, 2011).

10. Study of the health and disease of the “body politic” – the population. Basic science of public health What causes disease? How does disease spread? What prevents disease? What works in controlling disease?

11.  Descriptive  Analytic

12.  Descriptive epidemiology involves characterization of the distribution of health- related states or events by:  Person – who?  Place – where?  Time – when?  Clinical criteria – what?
