• The 25 locally acquired cases are mainly located in the municipalities of Chirongui, Bandrélé, and Dembéni;
• Of the 161 imported malaria cases in Mayotte, 95.6% originated in the Union of the Comoros;
• 71 cases required hospitalization (29.1%), including four admissions to the intensive care unit. No deaths were reported;
• Plasmodium falciparum is the species responsible for all cases reported in Mayotte in 2026;
