[Measures of impact in epidemiology].
After establishing a link between an exposure factor and occurrence of a disease, it is necessary to measure the impact on public health. The etiologic fraction, preventable fraction, and number of cases avoided can be used to measure such impact. The purpose of this article is to present the calculation and interpretation of these indicators using an example taken from the journal of Médecine Tropicale.
