The project is in line with the work on therapeutic mobility and circulation, which questions the production of socio-spatial inequalities in health, from a sociological and anthropological perspective. The subject of medical evacuations in the overseas territories is part of a reflection on therapeutic mobilities and circulations and the political conditions that frame them. The integration of Mayotte, one of the four islands of the Comoros archipelago, into the French territory in 2011 has resulted in migratory pressure from the other islands of the Comoros and in increasing control of mobility from them. For Comorians, however, reaching Mayotte is often the only way to access medical care, particularly for serious pathologies. However, the Mayotte hospital centre (CHM) suffers from a technical platform and medical staff that are largely understaffed. This is why people requiring care that cannot be provided locally are evacuated to Reunion Island. This medical evacuation system, or EVASAN system, is available to patients in a legal or illegal situation. In 2021, nearly 1,500 people were evacuated from Mayotte, 30% of whom were minors. For these minors, a parent is authorised to accompany them but this is not always possible due to various constraints: the presence of other dependent children in Mayotte, lack of financial support for the stay in Reunion, etc. The general objective of this research project is to understand the effects of this context (social, geopolitical, legal and institutional) on the trajectories of minors requiring care and their families.
