Learning outcomes of the course unit
Etiology is the branch of science concerned with the causes and origin of diseases. The prevention of disease must be founded on a dynamic approach that, taking into account the time-related changes of the etiological factors associated with each particular specific environment (geographic, socio-economic, etc.), be able to define the manifold interactions either potential (state of risk) or actual (cause of disease) occurring within a real environment and in the real time. The student must recognize these interactions between the organism and the environmental pathogenic factors in order to evaluate the inherent risks of disease and to anticipate the effects to come.
