Why are epidemiological measures useful quizlet?
Epidemiological measures are useful tools because: They help determine which diseases may need greater public health campaign or prevention efforts.
An estimated 1.8 million infected individuals died from the disease.
Calculate the incidence rate of tuberculosis per 100,000 in the population in 2015..
What are the basic principles of epidemiology?
Uses of EpidemiologyCount health-related events.Describe the distribution of health-related events in the population.Describe clinical patterns.Identify risk factors for developing diseases.Identify causes or determinants of disease.Identify control and/or preventive measures.More items…•
What are the epidemiologic measure of person?
Incidence, prevalence, and mortality rates are three frequency measures that are used to characterize the occurrence of health events in a population.
What are the 5 main objectives of epidemiology?
In the mid-1980s, five major tasks of epidemiology in public health practice were identified: public health surveillance, field investigation, analytic studies, evaluation, and linkages.
What is the strongest study design?
The most common and strongest interventional study design is a randomized controlled trial, however, there are other interventional study designs, including pre-post study design, non-randomized controlled trials, and quasi-experiments (1,5,13).
What kind of study would be best to study a rare disease?
Case-control studies are particularly efficient for rare diseases because they begin by identifying a sufficient number of diseased people (or people have some “outcome” of interest) to enable you to do an analysis that tests associations.
Which of the following is an indirect infectious disease transmission mode?
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.
How do epidemiologists figure out if a disease is transmissible?
Epidemiologists count cases of disease (or injury), consider the distribution of the cases, and define the affected population. If a problem is identified, they use data they collect to try to determine its cause and how it is being transmitted. They also recommend how best to control its spread within the population.
How do you confirm an outbreak?
An epidemic can be confirmed by comparing the incidence of the disease with that in the recent past or at a similar time in previous years for the same community. Alternatively, an outbreak may be confirmed if a number of cases are clustered and come from the same place at a similar time.
What is the 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.
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.
What are epidemiological methods used for?
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.
Do epidemiologists see patients?
Work Environment Field work may require interaction with sick patients, yet safety precautions ensure that the likelihood of exposure to disease is minimal. Epidemiologists typically work in offices and laboratories at health departments for state and local governments, in hospitals, and at colleges and universities.
Is 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.
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 the best definition for the epidemiological triangle?
The epidemiologic triangle is a model for explaining the organism causing the disease and the conditions that allow it to reproduce and spread.
What are the three components of the epidemiological triangle?
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 the three factors of the epidemiological triangle quizlet?
The epidemiological Triangle model includes three key elements: the agent, host, and environment.
What are the 3 main 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 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 feature is at the center of the epidemiological triangle?
f0005: The epidemiologic triangle. The host is the organism that gets the disease, the agent is the disease-causing organism, and the environment is that realm in which the interaction between the host and agent transpires.
