Abstract : Discriminations are differential treatments which are illegitimate and unfavorable in most cases.
Health care public policies led towards “poors” and foreigners are first presented.
Then are analysed interviews and observations conducted with 175 health care professionals in metropolitan France and in french Guyana, from 2001 to 2003.
A typology of origin based discriminations is built from the metropolitan datas. In the first two types, the professional justifies his or her discriminatory treatment by the otherness he perceives in the health care user. This otherness is mostly an illegitimacy in the first type, a difference in the second. The third type is produced by structural logics, independently of any perception of otherness.
Inserting this typology into a precisely located context, french Guyana, lets us understand how macro (geographic, demographic, politic, etc.) and micro (professionnel, instututionnal, etc.) social stakes articulate to each other in the process of discriminations in health care.
