Methods, simply as illnesses or scientists, have their very own historical past. it will be important for scientists to pay attention to the genesis of the tools they use and of the context during which they have been developed.

A historical past of Epidemiologic equipment and Concepts relies on a suite of contributions which seemed in "SPM foreign magazine of Public Health", beginning in January 2001. The contributions concentrate on the old emergence of present epidemiological equipment and their relative significance at assorted closing dates, instead of on particular achievements of epidemiology in controlling plagues resembling cholera, tuberculosis, malaria, typhoid fever, or lung melanoma. The papers current the layout of potential and retrospective reviews, and the strategies of bias, confounding, and interplay. The compilation of articles is complemented through an advent and reviews via Prof. Alfredo Morabia which places them within the context of present epidemiological research.

78). This observation can be extended to the first half of the 19'h century. There were septic fevers following amputations but also puerperal, choleric, yellow fever, slow fever, diarrheic fevers, smallpox, malaria, hepatitis, and ophthalmic infections. Fevers were everywhere and physicians did not know how to cure them. We will review here two episodes in which group comparisons yielded the correct answer about the treatment or the etiology of fevers, one in a clinical setting and the other in public health.

This distinction was sufficient in practice but lacked mathematical rigor. 3). Considering that cumulative incidence is a synonym for risk and incidence density a synonym for incidence rate, we must acknowledge that quite a theoretical distance had been covered between Farr's On Prognosis (Farr, 2003) and Miettinen's Estimability (Miettinen, 1976a). The developments have allowed epidemiologists to study more complex questions, more rigorously too. The future chapters of the evolution of population thinking in epidemiology are currently being written.

The fraction of these cases that can be attributed to a given risk factor was obtained by computing the product of prevalence of exposure and the attributable (or excess) risk. This finding had a major implication for prevention: an efficient prevention strategy should consider targeting the mass of the population and not only the minority that is at high risk for the trait (Rose, 1981). By the end of the 1960s, the distinction between risks and rates remained essentially conceptual: the number of incident cases was either divided by the number of persons at risk to form a risk, or it was divided by the number of person-times to form an incidence rate.
