The importance of descriptive epidemiology and its use in the investigation of these health problems, especially in view of epidemiologists' tendency to give less attention to it, finally, is emphasized the challenges that the emergent diseases pose for public health practice and for the methodological development of descriptive epidemiology are also set out. These challenges are considered in three fields: biosecurity, surveillance systems and descriptive epidemiology techniques.
