The objectives of epidemiology include the following: to identify the etiology or cause of disease. to study the progression of disease. to evaluate preventive and therapeutic measures for a disease or condition. The goal of any epidemiological study is to acquire an accurate picture of a particular health problem or disease. That information is used to create strategies for prevention and treatment of health conditions, preserve public health, implement better policies, and more. 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. 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. Epidemiology definition. Epidemiology is the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems.

Epidemiology offers powerful tools to quantify the degree to which risk factors and humanitarian interventions affect population health in a crisis. These tools include surveys, surveillance, analysis of programme data, and rapid assessment.

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.

Epidemiologists conduct two main types of analytic studies: experimental and observational. Experimental studies use a randomized selection process. A process based on chance is used to assign study subjects to different exposure groups.

Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in defined populations.

The epidemiologic triangle is made up of three parts: agent, host and environment. Agent. The agent is the microorganism that actually causes the disease in question. Host. The agent infects the host, which is the organism that carries the disease. Environment. HIV.

epidemiologist. plural. epidemiologists. Synonyms and related words. People who study specific subjects:archaeologist, archeologist, astrologer

Epidemiology is the study of diseases in given populations. Epidemiologists examine how and where disease outbreaks start, how diseases are transmitted among individuals in a population and how to effectively treat those diseases.

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).

Generally speaking, descriptive studies deal with the “what” questions, for example, describing “what happened” in terms of disease occurrence, while analytic studies ask the “why” questions, for example, why some people develop disease and others don't.

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.

Analytic Epidemiology. Analytic epidemiologic studies measure the association between a particular exposure and a disease, using information collected from individuals, rather than from the aggregate population.

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.

Section 4: Core Epidemiologic Functions. 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. (17) A sixth task, policy development, was recently added. These tasks are described below.

The goal of epidemiology is to establish causal factors for health issues in order to improve the health and safety of entire populations. A population can refer to a town, country, age group, or race. Health issues refer to anything that might impact health in the present or future.
