Epidemiologist
* also study the interaction of diseases in a population.
* are doctors
  - essential in tracking a disease and determining who is at risk
  - interested in the study of infectious and noninfectious diseases
  - public health professionals who study health and disease
  - scientists who track trends in diseases
* determine the frequency and pattern of health problems in different communities.
* develop studies to identify factors that cause diseases and injuries.
* look at the health patterns of large groups of people using statistical methods.
* overwhelmingly believe vaccinating swine has worked.
* posit no clear link between blood cholesterol and ischemic stroke.
* rely on statistical data.
* study the incidence, transmission, distribution, and control of disease
  - patterns and causes of diseases in population
  - what health problems occur in groups of people and investigate the causes
* suspect that the illness is spread through sexual intercourse between men.
* talk often about the efficiency of transmission.
* tend to talk in numbers, as most scientists do.
* typically have a graduate-level education.
* use informatics as a tool.
+ Epidemiology, The practice
  * Epidemiological studies are aimed, where possible, at revealing unbiased relationships between exposures such as alcohol or smoking, biological agents, stress, or chemicals to mortality or morbidity. The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology. Epidemiologists use informatics as a tool. The term 'epidemiologic triad' means the intersection of 'Host', 'Agent', and 'Environment' in analyzing an outbreak. Epidemiologists use the key term inference and gather data, a broad range of biomedical and psychosocial theories biology, sociology, mathematics, statistics, anthropology, psychology, and policy in an iterative way to generate or expand theory, to test hypotheses, and to make educated, informed assertions about which relationships are causal, and about exactly how they are causal. Since 1965 they use Bradford-Hill criteria for assessing evidence of causation.
+ Epidemiology: Public health
  * Epidemiologists work from outbreak investigation to study design, data collection and analysis including the development of statistical models to test hypotheses and the documentation of results. Epidemiologists also study the interaction of diseases in a population.

Immunologist
* Some immunologists believe that there are always malignancies in the body.
* are detectives of disease
* call it a collectin, rather than an opsonin.
* study the ways in which humans and other organisms resist illnesses.
