What are the components of epidemiology?

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.

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 do epidemiologists do?

When disease outbreaks or other threats emerge, epidemiologists are on the scene to investigate. Often called “Disease Detectives”, epidemiologists search for the cause of disease, identify people who are at risk, determine how to control or stop the spread or prevent it from happening again.

Who would use epidemiological data?

Who uses it? Researchers, health department officials, the government, and health or medical practitioners use epidemiology. This data is used to help identify priority health issues and possible causes of disease or illness.

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 the two goals of epidemiology?

The principal aim of epidemiology is to identify factors related to the occurrence of disease. Identification of these factors both causal ( causation) and risk factors, enable developing a rational basis for prevention ( epidemiology, prevention).

What are the two main types of studies that epidemiologists use?

Epidemiologic studies fall into two categories: experimental and observational.

What is the best study design?

Experimental Studies Randomized clinical trials or randomized control trials (RCT) are considered the gold standard of study design. In an RCT the researcher randomly assigns the subjects to a control group and an experimental group. Randomization in RCT avoids confounding and minimizes selection bias.

What are the four uses of epidemiology?

For community diagnosis of the presence, nature and distribution of health and disease among the population, and the dimensions of these in incidence, prevalence, and mortality; taking into account that society is changing and health problems are changing. To study the workings of health services.

How do Epidemiologists use statistics?

Statistics informs many decisions in epidemiologic study design and statistical tools are used extensively to study the association between risk factors and health outcomes.

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 difference between epidemiology and statistics?

Generally, the epidemiology degree has a greater emphasis on public health. The biostatistics MPH is built on using mathematical and statistical analysis regarding issues in public health and medicine. The biostatistics route is more focused on statistical analysis than the epidemiology path.
