📅 Report date: 12 Aug 2025 | Source: Public Health France & AFP
📊 Situation Overview
- 66 cases reported from January to July 2025
- 12 autochthonous (locally acquired) — first since July 2020
- 26 hospitalizations, 5 in ICU
- No deaths reported
- Majority of imported cases from Comoros, where malaria resurgence is ongoing
- Predominant species: Plasmodium falciparum (100% of cases)
📌 Why it matters
After years with only imported cases, the detection of local transmission marks a potential setback for malaria elimination in Mayotte. Historical records show nearly 2,000 local cases in 2002, falling to zero from 2020–2024. The reappearance in 2025 raises concern about vector resurgence and regional transmission chains.
🌍 Risk Factors & Vulnerable Groups
- High mosquito density in some areas
- Travel links with Comoros (ongoing outbreak)
- Children under 5 and pregnant women most at risk
- Environmental and climatic conditions favourable for Anopheles breeding
🔎 Public Health Implications
- Enhanced surveillance required to detect early spread
- Vector control measures need reinforcement
- Cross-border cooperation with Comoros critical
- Preventive measures for travellers: insect protection, chemoprophylaxis
📈 Outlook
Seasonal peaks, climate conditions, and continued importation from Comoros will determine the trajectory.
🚨 A rapid rise in local cases or the appearance of fatalities would signal escalating crisis risk.
💡 Global Risk Atlas will continue to monitor the situation and update as new data emerges.
