[The evolution of zoonoses].
Firstly, the author describes the evolution of the epidemiology of zoonoses, using examples of decreases and increases in incidence and of the probable 'birth' of zoonoses. Secondly, an analysis is presented of the main factors that may influence one of the components of a zoonosis (receptive animal populations, pathogens, external environment and humans), in addition to those factors responsible for changes in the epidemiology of zoonoses. Finally, a description is given of the main measures which can be applied within a given country or through international co-operation, to limit the development of zoonoses.
