Epidemiology was originally focused exclusively on epidemics of communicable diseases (3) but was subsequently expanded to address endemic communicable diseases and non-communicable infectious diseases.
Which of the following are part of epidemiology?
Epidemiology includes assessment of the distribution (including describing demographic characteristics of an affected population), determinants (including a study of possible risk factors), and the application to control health problems (such as closing a restaurant).

Epidemiology identifies the distribution of diseases, factors underlying their source and cause, and methods for their control ; this requires an understanding of how political, social and scientific factors intersect to exacerbate disease risk, which makes epidemiology a unique science.
What are the applications of epidemiology?
To diagnose the health of the community and the condition of the people , to measure the true dimensions and distribution of ill- health in terms of incidence, prevalence, disability, and mortal- ity; to set health problems in perspective and define their relative importance; to identify groups needing special attention ...
What are the 3 main elements of descriptive epidemiology?
