[Occupational risk: a sampling study in French-speaking Switzerland]

To prevent professional injuries and diseases, the need of analyzing risks at the work place from the individual as well as from collective point of view, is emphasized by law-makers. The present study shows that, using epidemiology enquiries allows one to analyse the prevalence of professional diseases in a population, without using the "LAA type" lists. One can see that these diseases, though linked to professional activity, go far beyond the limits of the insurance prescribed definitions.
