IntroductionThe investigation of the various determinants of human health and disease depends on various disciplines ranging from a tripartite mixture of scientific classes: biomedical sciences, clinical sciences and public sciences health sciences (Ahrens and Pigeot, 2005). According to MacMahon and Pugh (1970), epidemiology deals with studying how the frequency of diseases is distributed and what determines this distribution. Epidemiology, in attempting to investigate diseases of humans, depends on various aspects borrowed from other disciplines such as methodologies and concepts, but remains different from the same disciplines it borrows from.

First, epidemiology, being a study of diseases of the human body, borrows heavily from biochemistry. Biochemistry is strongly related to epidemiology and contributes to the discipline by providing reliable methodology and interpretation of chemical tests conducted to serve as the basis for diagnosis and administration of treatment (Gordis, 2014). Without biochemistry, it would be difficult for epidemiologists to understand the topic. Furthermore, epidemiology borrows heavily from biology to establish a clear understanding of human diseases in context. Other fields such as biostatistics play a vital role in epidemiology by providing a reliable tool for data analysis by epidemiologists as they seek to understand diseases in humans. Epidemiology also borrows from microbiology. Microbiology is primarily concerned with the study of microorganisms, and as such, epidemiology can use microbiological knowledge to understand pathogenic microorganisms such as bacteria and administer appropriate interventions. Despite epidemiology's dependence on various disciplines, it has significant differences in both approach and practice. Epidemiology, for example, deals with numerous aspects of human health that have no relation to microbiology, such as the degree of vulnerability, the trend of diseases such as obesity in selected population groups, as well as the determination of factors responsible for the spread of human diseases. Microbiology, on the other hand, is only concerned with the study of a wide range of organisms: both disease-causing organisms and non-disease-causing organisms. Biology on the other hand deals with numerous aspects of both plants and animals, unlike epidemiology which deals only with diseases of humans. Biochemistry is, on the other hand, a science with a main focus on the chemical and physiochemical processes that occur in living organisms, unlike epistemology which deals only with diseases of human beings (MacMahon and Pugh, 1970). : This is just an example.

The field is, however, distinct from the disciplines themselves from which it borrows some concepts, methodologies and practices.
