Seychelles travel health
Sources checked
Overview
Seychelles is a low‑malaria island destination where mosquito‑borne viral infections (dengue, chikungunya and occasionally Zika) are the principal infectious risk to most travellers; routine vaccines, food/water precautions and mosquito avoidance matter most. Entry vaccination requirements are limited but include a conditional yellow fever certificate for travellers coming from or transiting for more than 12 hours through a yellow‑fever risk country. Seek pre‑travel advice at least 4–6 weeks before travel if you need vaccines, have chronic illness, are pregnant, or plan prolonged stays or outdoor work on remote islands.
Health system and access to care
Basic and hospital care are available on the main island (Mahé) but specialist services are limited; serious injuries or complex medical problems may require evacuation. Visitors should carry travel insurance that covers medical evacuation and confirm where vaccines or rabies post‑exposure treatment are available. Ministry of Health, Seychelles.
Vaccinations and entry requirements
Separate legal/administrative entry requirements from clinical vaccine recommendations below. Decide on non‑mandatory vaccines with a clinician who knows your health, trip length and planned activities.
Entry requirements: yellow fever
Seychelles does not require routine vaccinations for most arrivals. A valid International Certificate of Vaccination against yellow fever is required only for travellers who have recently resided in or transited (for more than 12 hours at an airport) a country with risk of yellow fever transmission. Check your itinerary and the Government of Seychelles travel‑authorisation guidance before departure. Ministry of Foreign Affairs, Seychelles · Centers for Disease Control and Prevention (CDC) — Seychelles traveler page.
Routine and strongly recommended vaccines
Make sure you are up to date with routine immunizations (MMR, diphtheria‑tetanus‑pertussis, varicella, polio, seasonal influenza). Hepatitis A vaccination is recommended for unvaccinated travellers one year and older. Hepatitis B vaccination is recommended for travellers at increased risk (long stays, sexual activity with new partners, medical procedures, or occupational exposures). Typhoid vaccine is advised for most travellers who will eat or drink outside well‑regulated hotels and restaurants. COVID‑19 vaccination: travellers are advised to be up to date with their COVID‑19 vaccines; Seychelles currently has no COVID‑related entry requirements. CDC — vaccines & traveller guidance · Ministry of Foreign Affairs, Seychelles.
Rabies
Terrestrial rabies (infected dogs) has not been reported in Seychelles, but lyssaviruses have been detected in bats in the region. Rabies post‑exposure vaccines may only be available at larger Mahé facilities; rabies immunoglobulin can be difficult to obtain. Consider pre‑exposure rabies vaccination if you will work with bats or have planned prolonged remote travel where prompt post‑exposure treatment could be delayed. After any bite or scratch from a mammal or bat, wash the wound thoroughly and seek urgent medical care.

Dengue vaccine (Qdenga/TAK‑003) and travellers
No dengue vaccine is universally recommended for short‑term travellers from the United States. Where Qdenga (TAK‑003) is authorised, many national bodies limit use to people with documented prior dengue infection (or to defined groups). Vaccination decisions require proof of prior infection and specialist advice; vaccine availability and national recommendations vary by country. Regardless of vaccination, mosquito bite prevention remains essential. WHO — dengue vaccine Q&A · CDC Yellow Book — dengue.
Other health risks
Prioritise prevention measures that match the island environment: vector control for mosquitoes, food and water safety, sun and sea safety, and preparation for limited services on smaller islands.
Mosquito‑borne diseases (dengue, chikungunya, Zika)
Dengue has been endemic in Seychelles for years and remains the main mosquito‑borne disease; chikungunya circulation and occasional Zika detection have also been reported in recent seasons. These viruses cause fever, severe joint or muscle pain, rash and, for dengue, a small risk of severe disease. All travellers should use insect repellent (DEET, picaridin or IR3535), wear long sleeves and consider staying in screened or air‑conditioned accommodation. Mosquito avoidance protects against multiple diseases. Ministry of Health — annual performance & dengue data · European Centre for Disease Prevention and Control (ECDC) — chikungunya notice (Feb 27, 2026) · Ministry of Health — dengue/arbovirus resources.
Malaria
Seychelles is considered malaria‑free; routine antimalarial prophylaxis is not required for travel within the islands. Use standard mosquito bite precautions for arbovirus risk. If you plan travel to other nearby countries, check malaria advice for those destinations. CDC — malaria by country (Seychelles: none).
Leptospirosis and other local infections
Leptospirosis occurs in Seychelles and can present after freshwater exposure or contact with animal urine; avoid wading in floodwater, treat cuts promptly and seek care for febrile illness. Travel‑related food and water infections (traveller’s diarrhoea, typhoid, hepatitis A) are possible; follow safe food/water practices and consider vaccination for hepatitis A and typhoid when indicated. Ministry of Health — vital statistics & communicable disease tables · CDC — food, water and vaccine advice.
Injuries, marine risks and non‑infectious hazards
Water sports and boat trips are common—use approved life jackets, heed local weather and tide warnings, and be careful around coral and sea urchins. Heat, sunburn and jellyfish stings are hazards; bring sun protection and know local emergency contacts. Carry any routine medicines in original packaging and enough supply for your trip.

Current health alerts
Active or recently reported public‑health developments that concern travellers to Seychelles.
Ongoing arbovirus activity (dengue and chikungunya)
National surveillance and retrospective testing have shown ongoing dengue transmission in recent years, and public‑health authorities reported a rise in chikungunya cases in 2024–2026 that affected travellers returning to Europe. Travelers should assume there is ongoing local transmission, especially during the rainy season, and strictly follow mosquito‑bite prevention. ECDC — notice (27 Feb 2026) · Ministry of Health — dengue surveillance · Local reporting on arbovirus situation.
No routine COVID‑19 entry restrictions
Seychelles currently does not require proof of COVID‑19 vaccination or a negative COVID test for entry, but travellers should check airline and transit‑country rules, and be up to date with personal vaccination. Ministry of Foreign Affairs, Seychelles · CDC — traveller guidance.
Note: outbreak situations can change rapidly. The paragraphs above cite recent public‑health assessments; check the linked authorities shortly before travel for any new notices or local restrictions.

Preparation checklist
1) Review routine immunizations and get hepatitis A (and typhoid/hepatitis B if indicated) well before departure; 2) Ensure travel insurance covers medical care and evacuation; 3) Pack high‑quality insect repellent, a mosquito net or permethrin‑treated clothing if you will sleep outdoors, basic first‑aid supplies and any prescription medicines; 4) Confirm whether you need a yellow fever certificate based on your previous 6–12 week itinerary; 5) For animal exposures, know where post‑exposure care is available on Mahé.
