Question: What Are The Three Components Of The Epidemiological Triangle Quizlet?

Why is the epidemiological triangle important?

The Epidemiologic Triangle The Epidemiologic Triangle is a model that scientists have developed for studying health problems.

It can help your students understand infectious diseases and how they spread..

What are the key characteristics of epidemiology?

It extracts six types of epidemiological characteristic: design of the study, population that has been studied, exposure, outcome, covariates and effect size.

What is the role of epidemiology?

It is the scientific method of investigation problem-solving used by disease detectives— epidemiologists, laboratory scientists, statisticians, physicians and other health care providers, and public health professionals—to get to the root of health problems and outbreaks in a community.

What are the three components of epidemiology?

The epidemiologic triangle is made up of three parts: agent, host and environment.

What are the four methods of epidemiology?

Observational cohort. Observational case-control. Observational cross-sectional. Not an analytical or epidemiologic study.

What are epidemiological methods?

Epidemiology is the method used to find the causes of health outcomes and diseases in populations. In epidemiology, the patient is the community and individuals are viewed collectively.

What is epidemiologic 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 is the most common mode of indirect transmission?

Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air. If healthy people inhale the infectious droplets, or if the contaminated droplets land directly in their eyes, nose or mouth, they risk becoming ill.

What is a cause in epidemiology?

In epidemiology, the “cause” is an agent (microbial germs, polluted water, smoking, etc.) that modifies health, and the “effect” describes the the way that the health is changed by the agent. The agent is often potentially pathogenic (in which case it is known as a “risk factor”).

What are epidemiological issues?

Epidemiology has been defined as “the study of the distribution and determinants of health-related states or events in specific populations and the application of this study to control of health problems.”3 It tends, for the most part, to use the “medical model” of health need, viewing need in terms of the occurrence …

What are the three components of the epidemiologic triangle?

A number of models of disease causation have been proposed. Among the simplest of these is the epidemiologic triad or triangle, the traditional model for infectious disease. The triad consists of an external agent, a susceptible host, and an environment that brings the host and agent together.

What is epidemiology 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.

What are the 3 major types of epidemiological studies?

Three major types of epidemiologic studies are cohort, case-control, and cross-sectional studies (study designs are discussed in more detail in IOM, 2000). A cohort, or longitudinal, study follows a defined group over time.

What are the basic principles of epidemiology?

Principles of EpidemiologyDistribution – Epidemiology is concerned with the frequency and pattern of health events in a population. … Determinants – Epidemiology is also used to search for causes and other factors that influence the occurrence of health-related events.More items…•Nov 3, 2006

What is epidemiology quizlet?

Epidemiology. 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; the basic science for public health. Frequency.

What are the 5 W’s of epidemiology?

The difference is that epidemiologists tend to use synonyms for the 5 W’s: diagnosis or health event (what), person (who), place (where), time (when), and causes, risk factors, and modes of transmission (why/how).

What is an example of epidemiology?

Epidemiological studies measure the risk of illness or death in an exposed population compared to that risk in an identical, unexposed population (for example, a population the same age, sex, race and social status as the exposed population).

What are the epidemiological determinants?

In the definition of epidemiology, “determinants” generally includes the causes (including agents), risk factors (including exposure to sources), and modes of transmission, but does not include the resulting public health action.

What are the three most essential elements of descriptive epidemiology?

In descriptive epidemiology, we organize and summarize data according to time, place, and person. These three characteristics are sometimes called the epidemiologic variables.

What is the purpose of epidemiology quizlet?

The study of disease in groups or populations through the collection of data and information, to identify patterns and causes. Used by governments and health-related organisations to obtain a picture of the health status of a population.

What is an epidemiological study quizlet?
