São Tomé & Príncipe travel health
Sources checked
Overview
Prepare for mosquito‑borne infections, varying medical access and an official yellow fever vaccination requirement at entry. Routine childhood vaccines, protection against common travel infections (hepatitis A, typhoid) and a malaria plan are the highest‑priority items for most visitors.
Health system, travel logistics and insurance
Clinical services on São Tomé and Príncipe are limited outside the main towns; travellers are advised to carry adequate supplies of regular medicines, a travel insurance policy that covers medical evacuation, and documentation for prescriptions. CDC Travelers' Health • Ministry of Health, São Tomé & Príncipe.
Vaccinations and entry requirements
Separate legal entry requirements (what authorities at the border may demand) from clinical vaccine advice (what protects you medically). Check both your itinerary and transit points before travel.
Yellow fever (entry requirement)
São Tomé & Príncipe’s Ministry of Health states that a yellow fever vaccination certificate is required as a condition of entry and may be checked at arrival; travellers are advised to carry an International Certificate of Vaccination or Prophylaxis (ICVP). Some international guidance (for example CDC) considers yellow fever vaccination unnecessary for direct travel from non‑risk countries but still enforces proof if arriving from a country with yellow fever transmission. If there is any transit or recent travel from a country with yellow fever risk, obtain the vaccine at least 10 days before travel and carry the ICVP. Ministry of Health, São Tomé & Príncipe • WHO country list (yellow fever requirements) • CDC Travelers' Health.
Routine vaccines (MMR, DTP, polio, influenza, etc.)
Make sure you are up‑to‑date with routine vaccines before travel: measles‑mumps‑rubella (MMR), diphtheria‑tetanus‑pertussis, polio, seasonal influenza and varicella as appropriate. Because measles transmission has risen globally, ensure full MMR protection at least 2 weeks before departure. CDC Travelers' Health.
Hepatitis A, typhoid and hepatitis B
Hepatitis A vaccine is recommended for all unvaccinated travellers aged ≥1 year (and infants 6–11 months in some situations). Typhoid vaccine is recommended for most travellers, especially if you will eat or drink outside major hotels/restaurants. Hepatitis B vaccination is advised for unvaccinated travellers who may have sexual exposure, need medical care, or will stay long term. CDC Travelers' Health.
Rabies
Rabid dogs are present on the islands. Pre‑exposure rabies vaccine should be considered for travellers who will have occupational or prolonged outdoor exposure, handle animals, or may have delayed access to post‑exposure care. If exposed, prompt wound washing and medical attention (post‑exposure prophylaxis) are mandatory; rabies biologics may be limited locally. CDC Travelers' Health.
Other health risks
Key non‑vaccine risks for visitors and practical ways to reduce them.
Malaria
Malaria occurs across the islands and is primarily due to Plasmodium falciparum. CDC recommends that all travellers to São Tomé & Príncipe take an appropriate antimalarial medicine; options include atovaquone‑proguanil, doxycycline, mefloquine or tafenoquine depending on individual health, pregnancy status and drug interactions. Insect bite prevention (repellent with DEET/icaridin, long sleeves, bed nets) is essential. CDC Travelers' Health (malaria guidance) • WHO — World Malaria Report: São Tomé & Príncipe.
Dengue and other mosquito‑borne viruses
Dengue circulates in the region. There is no routine vaccination recommended for travellers to São Tomé & Príncipe; prevention relies on avoiding mosquito bites (repellents, screens, air‑conditioning, wearing long clothing and using bed nets when needed). CDC Travelers' Health (dengue and bite prevention).
Water‑ and food‑borne infections; schistosomiasis and leptospirosis
Traveler’s diarrhea, other enteric infections and intestinal parasites are common where water and sanitation are limited. Avoid untreated water and uncooked street food. Freshwater bodies may harbour schistosomiasis — avoid swimming or wading in lakes, rivers or untreated freshwater. Leptospirosis can be contracted from contaminated water or flooded areas. CDC Travelers' Health (food/water, schistosomiasis, leptospirosis).
Road safety and injuries
Road traffic accidents are a frequent cause of serious injury for travellers in many low‑resource destinations. Wear seatbelts, avoid night driving, use reputable taxis and ensure vehicle insurance/medical evacuation cover. CDC Travelers' Health (safety and packing checklist).
Current health alerts
Only alerts with clear public‑health relevance to travellers are listed below.
Measles — global increase
Measles activity has risen worldwide and many travel health authorities advise ensuring up‑to‑date MMR vaccination before international travel. This is a global risk rather than a São Tomé‑specific outbreak. CDC Travelers' Health (global measles notice) • WHO travel guidance (context).
Local outbreak situation
At the time of checking, the São Tomé & Príncipe Ministry of Health publishes routine epidemiological bulletins but did not list a current nationwide travel‑health emergency. Because situations can change rapidly, check official national bulletins and your government’s travel advisories shortly before departure. Ministry of Health, São Tomé & Príncipe (traveller information and bulletins) • CDC Travelers' Health (travel notices).
Before you travel
Simple checks and preparations reduce risk and prevent travel disruption.
Practical checklist
See a travel‑health clinician 4–8 weeks before departure (so vaccines can be completed and antimalarials started at the correct time). Carry an ICVP if you have yellow fever vaccination, bring sufficient prescription medicines and copies of prescriptions, pack insect repellent, a bed net if sleeping outside screened accommodation, and buy travel insurance that covers emergency evacuation. Confirm entry and transit vaccine/test rules with the airline and the São Tomé consulate before departure. CDC Travelers' Health • Ministry of Health, São Tomé & Príncipe.
