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 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 factors that affect how contagious infectious diseases spread?
Environmental factors influencing the spread of communicable diseases. Water, sanitation, food and air quality are vital elements in the transmission of communicable diseases and in the spread of diseases prone to cause epidemics.
What are the 3 factors that cause disease?
Infectious diseases can be caused by:Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.Fungi. … Parasites.
Which of these is an example of secondary prevention quizlet?
Examples of secondary prevention include: home visits by helpful nurses or social workers, as well as high-quality day care that gives vulnerable parents a break while teaching how to make friends and resolve conflicts.
Where does genetics belong within 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.
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 three components of the disease triangle?
These three elements, pathogen, host, and environmental conditions, make up the disease triangle. The disease triangle is a concept that illustrates the importance of all three elements—just as there are three sides to a triangle, there are three critical factors necessary for disease to develop.
What are the predisposing factors of disease?
Key PointsSome predisposing factors of contracting infectious diseases can be anatomical, genetic, general and disease specific.Climate and weather, and other environmental factors that are affected by them, can also predispose people to infectious agents.More items…•
What are the two types of epidemiology?
It has been said that epidemiology by itself can never prove that a particular exposure caused a particular outcome. Often, however, epidemiology provides sufficient evidence to take appropriate control and prevention measures. Epidemiologic studies fall into two categories: experimental and observational.
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 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 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 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 is a host in infectious disease?
A host in the context of infectious disease refers to an animal or plant that acts as a biological refuge in which another – often parasitic – organism may dwell. The host usually provides shelter or nourishment to the other organism, which may use the host to partially/completely sexually develop 1.
What are the 3 types of risk factors?
The three categories of risk factors are detailed here:Increasing Age. The majority of people who die of coronary heart disease are 65 or older. … Male gender. … Heredity (including race) … Tobacco smoke. … High blood cholesterol. … High blood pressure. … Physical inactivity. … Obesity and being overweight.More items…
What is tertiary prevention define and give examples?
Tertiary prevention—those preventive measures aimed at rehabilitation following significant illness. At this level health services workers can work to retrain, re-educate and rehabilitate people who have already developed an impairment or disability.
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 of the following is an example of tertiary prevention quizlet?
Physical therapy for stroke victims and exercise programs for heart attack victims are examples of tertiary prevention.
What are the 3 types of prevention?
The three levels of preventive care—primary, secondary, and tertiary care—are detailed below:Primary Prevention. Primary prevention aims to avoid the development of a disease or disability in healthy individuals. … Secondary Prevention. … Tertiary Prevention.
What are the three factors of the epidemiological triangle quizlet?
The epidemiological Triangle model includes three key elements: the agent, host, and environment.
