What about Epidemiology ?

Epidemiology is the study of the quantitative investigation of the factors that influence the state of health of the population. Epidemiological studies help identify those people more or less likely to have certain diseases. It also explores whether disease rates change over the years and in which areas certain diseases are particularly prevalent.

Epidemiological studies compare different populations to provide insightful results. These conclusions from epidemiological studies are very important for the management of the health system. Thanks to this research, it is possible to observe the health status of a population. Thus, based on epidemiological findings, public health programs for the early detection of diseases can be established.

Clinical medicine also benefits from epidemiology. Because epidemiology is not only concerned with infectious diseases and epidemics, but with all sorts of diseases. The epidemiological approach is often used to develop reliable guidelines and provides physicians with advice on which diagnostic tests and treatments are useful.

Epidemiology is mostly involved in designing research studies, data collection and analysis of results. The study results will be communicated to support decision makers in healthcare, clinics and the public.
