Some Case Studies and Situation Analyses
We have said in Sect. 1.1 that in the twentieth century the term “epidemiology” took a much wider meaning than before when it concerned only infectious diseases. This semantic transition reflected a transition of the “disease spectrum”; non-infectious ailments and injuries played now an increasing role. In Vietnam, we may indeed very well speak of “epidemics” of, among others, cancer, cardio-vascular diseases, type 2 diabetes, and injuries by crashes in road traffic. Hence, we will start the present chapter by describing a study about the descriptive epidemiology of traffic accidents.
