What is disease distribution?
In the definition of epidemiology, “distribution” refers to descriptive epidemiology, while “determinants” refers to analytic epidemiology. So “distribution” covers time (when), place (where), and person (who), whereas “determinants” covers causes, risk factors, modes of transmission (why and how).
What is the study of disease patterns?
Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in defined populations.
What is the study of the incidence and population distribution of disease called?
Epidemiology is the study of how often diseases occur in different groups of people and why.
What is the study of disease called?
The study of disease is called pathology. It involves the determination of the cause (etiology) of the disease, the understanding of the mechanisms of its development (pathogenesis), the structural changes associated with the disease process (morphological changes), and the functional consequences of those changes.
Which epidemic could best be treated by antibiotics?
Summary of antibiotic treatment recommendations Antibiotics are recommended in cholera-infected patients with serious dehydration, or moderate dehydration with continuing net fluid losses despite rehydration.
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 is disease and types of disease?
There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic diseases and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.
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 is the study of a disease pattern?
The study of the distribution and determinants of health-related states or events in specified populations, and the application of this study to control of health problems.
How does epidemiology relate to a defined population?
All findings must relate to a defined population A key feature of epidemiology is the measurement of disease outcomes in relation to a population at risk. The population at risk is the group of people, healthy or sick, who would be counted as cases if they had the disease being studied.
What is the study of Health event patterns?
The formal study of health event patterns in a population, their causes and means of prevention. Epidemiology provides the scientific basis for evidence-based medicine and strategies to improve public health. Segen’s Medical Dictionary. © 2012 Farlex, Inc.
Which is beyond the domain of the science of Epidemiology?
“Epidemiology is concerned with the incidence of disease in populations and does not address the question of the cause of an individual’s disease. This question, sometimes referred to as specific causation, is beyond the domain of the science of epidemiology.
What does the term pattern mean in epidemiology?
Pattern refers to the occurrence of health-related events by time, place, and person. Time patterns may be annual, seasonal, weekly, daily, hourly, weekday versus weekend, or any other breakdown of time that may influence disease or injury occurrence.
When do you use the term disease in epidemiology?
Indeed, the term health-related states or events may be seen as anything that affects the well-being of a population. Nonetheless, many epidemiologists still use the term “disease” as shorthand for the wide range of health-related states and events that are studied.
What is the definition of a determinant in epidemiology?
Determinant: any factor, whether event, characteristic, or other definable entity, that brings about a change in a health condition or other defined characteristic. Epidemiology is also used to search for determinants, which are the causes and other factors that influence the occurrence of disease and other health-related events.
What does frequency mean in terms of Epidemiology?
Frequency refers not only to the number of health events such as the number of cases of meningitis or diabetes in a population, but also to the relationship of that number to the size of the population. The resulting rate allows epidemiologists to compare disease occurrence across different populations.
