For studying states of health and illness
How is epidemiology used as a body of knowledge
Results from the study of a specific state of health or illness
What is the goal of epidemiology?
Preventing or limiting consequences and to maximize health status
What is an epidemic?
An outbreak that occurs when there is an increased incidence of disease beyond that which is normally found in the population
What is rates?
The primary measurement used to describe either the occurrence or the existence of a specific state of health or illness
Discoveries in early attempts at understanding the reasons for disease were direct result of what
Trial and error observations of individual people

Nutritional (proteins, fats, water, vitamins)
Psychosocial (stress, social, isolation, social report)

the interaction or interplay between physical biological and social environment De-emphasizing the
Agent as the sole cause of disease
What model emphasizes multiple causation in order to interrupt the chain of adverse events?
The web of causation

A model strongly, emphasizing multiple causations to design ways to interrupt the chain of adverse events
Direct and indirect factors can be identified .) drug use
