# How Do You Break The Epidemiologic Triangle?

## Do epidemiologists use math?

When Math is Used: Epidemiologists use mathematical models in order to track the progress of most infectious diseases.

They may also discover the likely outcome of an epidemic or to help manage them by vaccination..

## 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 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).

## Where does genetics belong in the epidemiological triangle?

The first element of the epidemiologic triad is the host organism – in human genetics, it is the person or human. The second element is the agent, which is either the genetic composition of the host, an infectious agent such as a virus, or an environmental factor such as smoking or cholesterol.

## 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 are the 3 main elements of descriptive epidemiology?

Descriptive epidemiology covers time, place, and person. Compiling and analyzing data by time, place, and person is desirable for several reasons.

## What is the agent in the epidemiologic triangle?

The Agent—“What” The agent is the cause of the disease. When studying the epidemiology of most infectious diseases, the agent is a microbe—an organism too small to be seen with the naked eye. Disease-causing microbes are bacteria, virus, fungi, and protozoa (a type of parasite).

## What are the three factors of the epidemiological triangle quizlet?

The epidemiological Triangle model includes three key elements: the agent, host, and environment.

## Why are some diseases legally reportable?

Reporting allows for the collection of statistics that show how often the disease occurs. This helps researchers identify disease trends and track disease outbreaks. This information can help control future outbreaks.

## Which federal government agency is the primary source for quality delivery of health services group of answer choices?

The Agency for Healthcare Research and Quality (AHRQ) is the lead Federal agency charged with improving the safety and quality of America’s health care system.

## What are epidemiological factors?

1: Epidemiologic Factors Events, characteristics, or other definable entities that have the potential to bring about a change in a health condition or other defined outcome.

## What are the three factors of the epidemiological 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.
