Immigrants living in France account for one third of new cases of infection and are a target population for prevention. Care givers should adapt their management practice, taking into account this population's specificities which are not restricted to cultural differences but include major socioeconomic factors. In addition to training on alien rights and basic sociocultural knowledge, care-givers (especially clinicians) must spend more time with the patient (especially at the beginning of the relationship) and accept sharing the "medical power" with other people with a better knowledge of other aspects of the patients' life in addition to the medical one. As in other chronic diseases, mediation is one of the available tools with evident benefits for any patient. Assuming compliance is the same for migrants as for other patients, using this mediation will warrant therapeutic success.
