For community diagnosis of the presence, nature and distribution of health and disease among the population, and the dimensions of these in incidence, prevalence, and mortality; taking into account that society is changing and health problems are changing. To study the workings of health services.

What is epidemiological evidence?

Unlike laboratory experiments, epidemiology provides evidence based on studies of human populations under real-world conditions. It largely avoids the extrapolations across species and levels of exposure that are required for the use of data from animal experiments, and which contribute large uncertainties.

What are the two types of epidemiology?

Epidemiologic studies fall into two categories: experimental and observational.

Who would use epidemiological data?

What is an epidemiologic triangle?

The Epidemiologic Triangle, sometimes referred to as the Epidemiologic Triad, is a tool that scientists use for addressing the three components that contribute to the spread of disease: an external agent, a susceptible host and an environment that brings the agent and host together.
