Elements of Epidemiology

Epidemiology is defined as the study of the distribution of diseases and their determining factors [1, 2]. In the field of environmental health, it thus investigates the relationship between different aspects of environmental exposure and human health. Epidemiology does not consider individuals, but rather groups of individuals specified by some common characteristic, e.g., exposure to some given substance, a pathology, etc. It then compares these groups of individuals, for example, to answer a question like: when individuals are exposed to a given substance, are they more often affected by a certain pathology?
