Critical-thinking skills.

Detail oriented.

Math and statistical skills.

Teaching skills..

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 are the 3 main elements of the definition of epidemiology?

Epidemiology includes assessment of the distribution (including describing demographic characteristics of an affected population), determinants (including a study of possible risk factors), and the application to control health problems (such as closing a restaurant).

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 are the key concepts of epidemiology?

Epidemiology is based on two fundamental assumptions. First, the occurrence of disease is not random (i.e., various factors influence the likelihood of developing disease). Second, the study of populations enables the identification of the causes and preventive factors associated with disease.

Is an epidemiologist a doctor?

Are epidemiologists considered medical doctors? No. While epidemiologists study and investigate the causes and sources of diseases in much the same way as medical doctors, they’re not considered actual physicians. Perhaps the biggest reason why is treatment.

What is the most important thing an epidemiologist does?

Epidemiologists study outbreaks of diseases, the causes, locations, and how various communities are affected, utilizing relative information to aid in the prevention of future outbreaks. Epidemiologists help to keep the public informed of methods to maintain and improve public health.

What is the strongest study design?

A well-designed randomized controlled trial, where feasible, is generally the strongest study design for evaluating an intervention’s effectiveness.

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).

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.

What are the three components 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.

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.

Who is the first epidemiologist?

Epidemiology has helped develop methodology used in clinical research, public health studies and, to a lesser extent, basic research in the biological sciences. The Greek physician Hippocrates is known as the father of medicine, and was the first epidemiologist. Hippocrates sought a logic to sickness.

What are the three factors of the epidemiological triangle quizlet?

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

What is epidemiological 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.

Which is the most powerful epidemiological study?

Randomized, controlled clinical trials are the most powerful designs possible in medical research, but they are often expensive and time-consuming. Well-designed observational studies can provide useful insights on disease causation, even though they do not constitute proof of causes.

Which would be considered agents in the epidemiological triangle?

The Agent—“What” 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).
