Mayotte travel health
Sources checked
Overview
Mayotte is a French overseas department in the western Indian Ocean. Key preparation points: protect against mosquito-borne disease (dengue/chikungunya and malaria); confirm routine and travel vaccines (hepatitis A, hepatitis B, typhoid where applicable); know yellow fever certificate rules for arrivals from endemic countries; and expect effects from seasonal weather and limited local health resources after recent storms.
Health system and access to care
Medical services exist in Mamoudzou and larger towns but capacity can be limited, especially after recent cyclones and heavy seasonal demand—plan insurance and evacuation if needed. See local public-health monitoring from Santé publique France and reporting on post‑cyclone pressure on services. Santé publique France regional bulletin, Le Monde report on cyclone impact.
Vaccinations and entry requirements
Separate legal entry requirements from routine and recommended vaccinations for personal protection. Review your individual medical history with a travel-health professional.
Yellow fever — entry certificate (administrative)
Mayotte requires a valid yellow fever certificate for travellers aged ≥1 year who are arriving from countries with risk of yellow fever transmission, and for travellers who have transited for more than 12 hours through airports in those countries. This is an administrative requirement, not a routine recommendation for direct travellers from low‑risk countries. Check the WHO IHR country list and national guidance for your route. WHO IHR yellow fever list, CDC Mayotte travel page.
Routine vaccinations
Be up to date with routine vaccines before travel, including measles‑mumps‑rubella (MMR), tetanus/diphtheria/pertussis, polio and influenza where appropriate. Measles remains a global risk for unvaccinated travellers. CDC travel recommendations.
Hepatitis A and hepatitis B
Hepatitis A vaccination is recommended for most travellers to Mayotte because transmission occurs and local cases are reported. Hepatitis B vaccination is routinely recommended for travellers who may have prolonged stays, sexual exposure, medical procedures, or other blood exposure. CDC: Hepatitis A & B advice.
Typhoid
Consider typhoid vaccine if you will be visiting rural areas, staying long-term, or eating in settings with uncertain sanitation (visiting friends/relatives or long stays). Practice safe food and water hygiene regardless of vaccination. CDC typhoid guidance.
Rabies (pre‑exposure)
Dogs with rabies are not commonly reported in Mayotte, but animal exposures can occur. Pre‑exposure rabies vaccination should be considered for travellers with occupational or prolonged outdoor exposure, or where prompt access to post‑exposure prophylaxis may be difficult; note that rabies vaccine and immunoglobulin availability may be limited outside major centres. CDC rabies advice.
How recommendations may differ
Some French authorities and travel-health bodies interpret risk differently. For example, French travel guidance has stated that routine malaria chemoprophylaxis is not required for Mayotte, while the U.S. CDC (and the Yellow Book) recommends antimalarial prophylaxis for travellers to Mayotte because of recent locally acquired cases. Discuss route, length and planned activities with your clinician to choose the right plan. French health recommendations (HCSP / Ministère), CDC travel page.
Other health risks
Non‑vaccine risks that commonly affect travellers in Mayotte and practical prevention steps.
Mosquito-borne illnesses (dengue, chikungunya, Zika)
Aedes-borne viruses circulate in the region. Protect against daytime-biting Aedes mosquitoes using repellents (DEET/icaridin/PMD as approved), long sleeves, and screens. There is no widely recommended vaccine for travel against chikungunya; dengue vaccines are limited by prior‑infection criteria and not for routine travellers. Santé publique France regional surveillance, CDC mosquito-borne disease advice.
Malaria
Locally acquired P. falciparum malaria re‑emerged in 2025 and cases continued into 2026. French public-health guidance has at times considered chemoprophylaxis unnecessary for routine short stays, while the CDC recommends antimalarial prophylaxis for travellers to Mayotte; all travellers should use mosquito protection and seek rapid medical attention for fever during travel or up to a year after return. Choose prophylaxis after clinical discussion. Santé publique France malaria bulletin, CDC malaria recommendations.
Leptospirosis and water‑linked infections
Leptospirosis incidence in Mayotte has been elevated (notably in 2025 and early 2026), often associated with flooding and rodent exposure. Avoid wading in floodwater, use protective footwear, and seek care for febrile illness after freshwater exposure. Santé publique France leptospirosis report.
Hepatitis A and enteric infections (typhoid)
Hepatitis A cases have been reported in 2026. Food- and water‑borne infections are a risk where sanitation is poor—use bottled or treated water, avoid raw shellfish and uncooked street food, and consider hepatitis A and typhoid vaccines when appropriate. Santé publique France: hepatitis A surveillance, CDC food & water guidance.
Injury and environmental hazards
Coastal currents, coral and jellyfish cause frequent injuries—use caution when swimming, wear protective footwear, and carry a basic first‑aid kit. Road and occupational safety can differ from what travellers expect; plan transport and local contacts. CDC traveller safety tips.
Current health alerts
The items below reflect active, destination‑specific surveillance up to the sources checked on 27 October 2026.
Malaria: local transmission detected (2025–2026)
Surveillance detected a resurgence of locally acquired P. falciparum malaria beginning in 2025 with additional cases in 2026. Travelers should follow mosquito-bite prevention and consult a clinician about prophylaxis; seek immediate testing for any febrile illness. Santé publique France malaria bulletin, CDC malaria guidance updated 2026.
Leptospirosis: elevated case numbers (2025–2026)
Confirmed leptospirosis cases were markedly higher in 2025 with continuing reports in 2026; risk increases after heavy rainfall or flooding. Avoid floodwater, wear protection for wet work, and see local care for fever and severe symptoms. Santé publique France leptospirosis report.
Hepatitis A and mpox reporting
Public-health surveillance reported multiple hepatitis A cases during 2026 and mpox cases identified locally; these are under routine public‑health follow-up. Vaccination and food/water precautions reduce risk for hepatitis A; follow specific precautions for mpox if engaging in higher-risk intimate contacts. Santé publique France regional bulletin, CDC mpox and hepatitis A information.
Before you travel
Prepare by reviewing vaccines, packing a travel-health kit, and planning access to care and insurance.
Practical checklist
Actions to take before departure: confirm routine and travel vaccines (MMR, hepatitis A/B, consider typhoid and rabies where appropriate); discuss malaria prophylaxis with a clinician and bring insect repellent and bednet where needed; pack prescriptions and a fever plan (where to test and seek care); and check whether your arrival route requires a yellow fever certificate. Official guidance from Santé publique France and CDC can help tailor choices to your itinerary. French travel-health recommendations (HCSP / Ministère), CDC Mayotte traveller page, WHO IHR yellow fever list.
