[Migration and administrative detention: the challenges for medical practice].

Administrative detention or deprivation of liberty of migrants is a response to a decision by the authorities to remove those who have refused to leave voluntarily. These people are incarcerated not for having committed a crime, but for staying illegally in Switzerland. They often find themselves in a precarious situation, suffering from psychological or somatic illnesses that may be linked to their migration path. In most cases, they do not wish to return to their country and have many psychological or physical defences to oppose the decision of the authorities organising the removal. The health care provider is therefore faced with many challenges in order to carry out the many tasks of prison medicine while respecting fundamental ethical principles.
