Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials.
Furthermore, what does epidemiology include?
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).
Similarly, what is epidemiology in health care? Epidemiology. Epidemiology is the study of the distribution and determinants of health-related states or events (including disease), and the application of this study to the control of diseases and other health problems.
Thereof, what are the 5 W’s of epidemiology?
However, epidemiologists tend to use synonyms for the five W’s listed above: case definition, person, place, time, and causes/risk factors/modes of transmission. Descriptive epidemiology covers time, place, and person. Compiling and analyzing data by time, place, and person is desirable for several reasons.
What are the five objectives of epidemiology?
The objectives of epidemiology include the following:
- to identify the etiology or cause of disease.
- to determine the extent of disease.
- to study the progression of disease.
- to evaluate preventive and therapeutic measures for a disease or condition.
- to develop public health policy.

What is basic epidemiology?
As the basic science of public health, epidemiology includes the study of the frequency, patterns, and causes of health-related states or events in populations, and the application of that study to address public health issues. Two essential concepts of epidemiology are population and comparison.
What is the difference between descriptive and analytic epidemiology?
Descriptive study types include the case report, cases series, and incidence studies. Analytic studies, on the other hand, should be performed if hypotheses exist for risk factors and diseases, and if these hypotheses need to be tested. Analytic studies fall into two categories: experimental and observational.
How is descriptive epidemiology used?
Descriptive epidemiology provides a way of organizing and analyzing these data in order to understand variations in disease frequency geographically and over time, and how disease (or health) varies among people based on a host of personal characteristics (person, place, and time).
What is descriptive epidemiology PDF?
Descriptive epidemiology is primarily concerned. with documenting the magnitude of a disease or. injury problem, and describing it in terms of the. personal characteristics and behavior of those at. risk, and the place and timing of occurrence.
What is a descriptive analytical study?
Descriptive studies involve detailed investigations of individuals in order to improve knowledge of disease. Descriptive studies often have no prior hypotheses and are opportunistic studies of disease whereas analytical studies are used to test hypotheses by selection and comparison of groups.
How do you calculate incidence rate?
Therefore, the term ‘person-year’ was used, which was defined as the number of quarters of the year that a patient was registered in a general practice. Incidence rates were calculated as the sum of all new episodes of illness of a certain disease in 2012 divided by the size of the population.
What are the advantages of epidemiology?
Major among epidemiology’s advantages is that the information is of direct relevance. The majority of epidemiology data are observation and whether the number of studies is broad enough, the data can be generalized to major segments of the population.
