Epidemiology
* Apply specific criteria in identifying nosocomial infections.
* Link to information sources about infectious diseases and related fields.
* branch of medical research that is increasingly in the public eye.
* can help identify causes as well as guide prevention efforts.
* deals with the distribution and determinants of disease in populations.
* focuses on human groups, individuals and ecosystems.
* has a vital role to play in defining heath care priorities.
* investigates diseases as a way to reduce mortality and morbidity.
* involves the association of diseases to risk factors and human exposures.
* is about information.
* is an approach to study of diseases such as cancer
  - objective, scientific method of problem solving based on quantitative analysis
* is based in science and a dose of practical common sense
  - on observations of human health and air pollution
  - integral to medical research
* is one of the basic sciences of public health and preventive medicine
  - cornerstones of public health
  - fields that applies such tools extensively
  - started and continued throughout the process of the course of the disease
  - still in an embryonic stage
  - the basic science of public health
* is the foundation of public health policy and practice
  - on which all preventative medicine is based
* is the science of identifying trends and patterns in the occurrence of health problems
  - that studies how diseases occur in a community
  - which studies the determinants of health and disease
  - scientific discipline concerned with the causes and prevention of human disease
  - study of determinants of health in a population
* is the study of disease and disease patterns in populations
  - incidence in defined populations
  - rates and patterns
* is the study of diseases in large populations
  - health problems among specific populations
* is the study of how diseases spread across human populations
  - infectious diseases move through populations
  - often diseases occur in different groups of people and why
* is the study of patterns in disease
  - of disease in the population
  - populations to seek the causes of health and disease
* is the study of the cause and distribution of disease in a population
* is the study of the distribution and causes of disease in populations
  - and prevalence of communicable disease in populations
  - of disease and health in human populations
* is the study of the factors that cause a disease to be present or absent
  - that cause or encourage diseases
* is the study of the frequency and distribution of disease in human populations
  - and distribution of diseases within human populations
  - health status of populations
* is the study of the occurrence of a disease and the factors that influence it
  - of disease in a human population
  - of human diseases
  - of infections or disease in a population
  - patterns, causes and prevention of human diseases
  - what makes people sick
  - who gets cancer and why
  - systematic method of identifying hazards and quantifying the magnitude of risk
  - thus the science of public health
  - useful only in studying high disease rates or rare diseases, and preferably both
  - very useful for suggesting possible links between cause and effect
* key factor for right strategy in diseases s prevention.
* looks at patterns of disease, diabilities, and mortalities in communitites and nations
  - sickness on a population scale
* plays a greater role in risk assessment
  - role in health scares and toxic torts
* provides a unique way of viewing and investigating disease and injury.
* quantitative science.
* rather crude science of counting and estimation.
* refers to the frequency and distribution of disease.
* shows some potential causes of cancer.
* slow, often painful process, full of false starts and dead ends.
* still remains the best available tool for identification of risk factors.
* studies the cause and control of epidemics.
* tries to link a chemical exposure to some observed ill.
* varies with cause.
* very complex science.
+ Disease, Epidemiology:
  * Epidemiology is the study of the cause of disease. Some diseases are more popular for people with common characteristics - like similar origins, sociological background, diet or nationality.
