The definition of epidemiology ends with the following phrase: “…and the application of this study to the control of health problems.” While some academically minded epidemiologists have stated that epidemiologists should stick to research and not get involved in policy development or even make recommendations, ( 24 ) public health epidemiologists do not have this luxury. Centers for Disease Control and Prevention. Epidemiology as a science is defined as “the study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to the control of health problems”(1). The classic definition of Epidemiology is that it studies the distribution determinants of health and health related things in populations with the goal of developing interventions and policies to improve health.

Epidemiology means determining the extent and distribution of diseases in different communities, which is referred to as descriptive epidemiology, and also is concerned with the evaluation of determinants or causative factors leading to a high or low prevalence of a disease in different populations, which is referred to as analytical epidemiology. Although its development may be traced back to the scientific revolution of the 1600s, it was not until the 19th century that it was recognised as a subject area in its own right.

Compartmental models simplify the mathematical modelling of infectious diseases.The population is assigned to compartments with labels – for example, S, I, or R, (Susceptible, Infectious, or Recovered).People may progress between compartments. Rothman KJ. MMWR Recommendations and Reports 2001:50(RR13). The purpose of public health surveillance, which is sometimes called “information for action,” (18) is to portray the ongoing patterns of disease occurrence and disease potential so that investigation, control, and prevention measures can be applied efficiently … Evaluation of an immunization program, for example, might assess the efficiency of the operations, the proportion of the target population immunized, and the apparent impact of the program on the incidence of vaccine-preventable diseases.

Certainly methods are an essential aspect of the field, and this text covers the usual complement. This is accomplished through the systematic collection and evaluation of morbidity and mortality reports and other relevant health information, and the dissemination of these data and their interpretation to those involved in disease control and public health decision making.
