Key Points

• At the Mayotte Hospital Center (CHM), the number of emergency room visits remained stable during week 2025-S09 (February 24 to March 2). Wounds and trauma remained the primary reason for emergency room visits, but their proportion was slightly down. Conversely, the share of visits due to decompensation of chronic diseases tended to increase.

• Traumas were once again the main reason for visits to the SSFMT (Secouristes sans frontières medical team) in 2025-S09, ahead of skin conditions, whose share was down compared to the previous week. As a reminder, this facility took over from ESCRIM on February 4, 2025. It does not have inpatient beds or an operating room.

• In 2025-S09, only one reference medical center (CMR) submitted its activity data. Gastrointestinal symptoms and trauma were the main reasons for seeking care.
