Madagascar travel health
Sources checked
Overview
Key preparation and exposure points for most visitors: malaria is widespread outside the capital and must be planned for; routine and travel vaccines (hepatitis A, typhoid, tetanus, measles, etc.) are important; animal bites and rabies are a practical risk with limited local access to advanced post‑exposure care; and Madagascar reports periodic plague activity and other outbreak-prone infections that sometimes include pneumonic (person‑to‑person) cases. Health services are limited outside Antananarivo and larger towns — arrange insurance and evacuation plans if you will travel to remote areas.
Health-system access and practical preparation
Medical facilities in Madagascar are basic outside major cities; supplies and specialist care (including rabies immune globulin and intensive care) may be unavailable in rural districts. Consider travel health and medical‑evacuation insurance, carry an adequate supply of regular medications, and plan for slow or unreliable transport. U.S. Department of State · Centers for Disease Control and Prevention (CDC).
Vaccinations and entry requirements
Separate legal entry rules from medical recommendations. Verify personal vaccine status well before travel and carry paper or digital vaccine records where required.
Entry vaccine requirements — Yellow fever
Madagascar requires an International Certificate of Vaccination against yellow fever for travellers arriving from countries with risk of yellow fever transmission (this can include transits of more than 12 hours through such countries). The requirement applies to travellers aged 9 months and older coming from affected countries; routine visitors from countries without yellow fever transmission are not routinely required to show a certificate. Follow the International Health Regulations and check your airline and Madagascar authorities before departure.

Vaccines widely recommended for travellers
Ensure routine adult and childhood vaccines are up to date (measles/MMR, tetanus‑diphtheria/pertussis, polio as per your national schedule). Hepatitis A is recommended for most travellers to Madagascar. Typhoid vaccine is recommended for travellers who may eat or drink in settings with uncertain sanitation (street food, rural stays). Hepatitis B should be given when there is potential exposure to blood/body fluids, sexual contact, or medical procedures. COVID‑19: be up to date with eligible vaccines before travel. CDC — Madagascar travel page · TravelHealthPro (NaTHNaC).
Vaccines for selected travellers
Rabies pre‑exposure vaccination should be considered for travellers who will have extended stays, work with animals, or visit remote areas where prompt post‑exposure prophylaxis may be unavailable. Polio: Madagascar has experienced circulating vaccine‑derived poliovirus activity in 2026 and national vaccination campaigns; ensure children are fully protected and adults who will work in health or humanitarian settings or have prolonged stays discuss an IPV booster with their clinician. Discuss individual needs (e.g., pregnancy, underlying conditions) with a travel‑health clinician.

Other health risks
Non‑vaccine risks that commonly affect visitors and pragmatic prevention steps.
Malaria
Malaria transmission occurs widely in Madagascar; the CDC classifies nearly all areas as malaria risk except for uncommon cases in Antananarivo. Chemoprophylaxis is recommended for travel to areas outside the capital — commonly used options include atovaquone‑proguanil, doxycycline, mefloquine, or tafenoquine (choice depends on medical history and G6PD status). Mosquito‑avoidance (DEET or picaridin repellents, permethrin‑treated clothing, bed nets) is essential both day and night. CDC — Malaria information by country · WHO — Madagascar malaria profile.
Mosquito‑borne arboviruses (dengue, chikungunya, Zika)
Aedes mosquitoes transmit dengue and chikungunya in Madagascar; local clusters have been reported in recent seasons. There is no widely available vaccine for dengue for most travellers — prevention relies on avoiding mosquito bites (repellents, clothing, screens). Pregnant travellers should discuss Zika with their clinician if they have concern about exposure. WHO — arbovirus surveillance and regional updates · Institut Pasteur de Madagascar — arbovirus reference.
Schistosomiasis and freshwater exposure
Schistosoma species are present in Madagascar; freshwater swimming, wading or other contact in rivers, lakes or streams can transmit infection. Avoid freshwater exposure where sanitation is uncertain; seek testing if you had freshwater contact and develop compatible symptoms. CDC — schistosomiasis guidance · Government of Canada travel health.
Animal bites, rabies and post‑exposure care
Dog and other mammal rabies are common in Madagascar. If bitten or scratched, wash wounds immediately with soap and water and seek medical care for rabies post‑exposure prophylaxis (RIG and vaccine) — but RIG and timely care may not be available outside larger towns. Consider pre‑exposure rabies vaccination for higher‑risk itineraries; pre‑exposure vaccination does not replace urgent post‑exposure care but simplifies it if available. CDC — rabies travel advice · TravelHealthPro — rabies risk.
Food, water and travellers’ diarrhoea
Food‑ and waterborne infections are common. Use safe‑food practices: drink bottled or boiled water, avoid uncooked street foods and unpeeled fruit unless you prepare it yourself. Carry oral rehydration salts and a prescribed antibiotic for moderate‑to‑severe travellers’ diarrhoea if advised by your clinician. CDC — travellers’ health.
Current health alerts
Only alerts with clear, current evidence are listed; local conditions can change rapidly — check official channels close to departure.
Plague — localized confirmed and suspected cases (October 2026)
In October 2026 Malagasy health authorities and multiple news outlets reported several confirmed and suspected human plague cases (including pneumonic presentations) in the south‑east (Midongy Atsimo / Midongy) and a small number of other districts. Pneumonic plague can spread by respiratory droplets and requires prompt antibiotic treatment and public‑health measures. Most travellers are at low risk if they avoid close contact with sick people and with sick or dead animals, but visit health services promptly for febrile or respiratory illness. This situation is evolving; travellers should review official national or WHO updates before travel. CIDRAP News — plague situation · International news report citing Malagasy authorities · WHO AFRO — plague background and sitreps.
Mpox (monkeypox) — national transmission since December 2025
Madagascar has experienced sustained mpox transmission beginning in late 2025 and continuing through 2026, with thousands of reported cases in 2026. Mpox spreads mainly through close skin‑to‑skin contact (including sexual contact), contaminated bedding or clothing, and less commonly via respiratory droplets from prolonged face‑to‑face contact. Travellers with close contact exposures or with immunosuppression should discuss risk reduction and testing with a clinician. WHO — mpox external situation report #68.
Polio-related activity (2026)
During 2026 Madagascar reported circulating vaccine‑derived poliovirus (cVDPV1) detections and has undertaken national vaccination campaigns. For travellers, ensure routine polio vaccination is complete; groups with prolonged stays or who will work in health or child‑facing settings should discuss an inactivated polio vaccine (IPV) booster with their clinician. WHO Africa — polio updates · TravelHealthPro — polio note.
Before you travel
Plan vaccines and malaria prevention, confirm entry rules, and prepare for limited care in remote areas.
Practical checklist
6–8 weeks before travel: see a travel‑health clinician to review vaccines (hepatitis A, typhoid, tetanus, MMR, hepatitis B as needed), discuss rabies pre‑exposure if at risk, and get malaria chemoprophylaxis for travel outside Antananarivo. Pack insect repellent (DEET/picaridin), a bed net if sleeping outside urban housing, water purification or bottled water, first‑aid supplies, and copies of vaccination records. Purchase travel health and medical‑evacuation insurance and check which entry vaccinations or certificates (yellow fever) apply to your itinerary.
