Yellow fever certificate required if arriving from a risk country

Equatorial Guinea requires proof of yellow fever vaccination from travelers aged 9 months and older arriving from a country with risk of YF transmission. Direct travel from Switzerland does not trigger this rule, but the vaccine is still medically recommended. Carry your International Certificate of Vaccination if you have transited or stayed in a YF-risk country; give the vaccine ≥10 days before arrival.

Vaccines

VaccineRecommendationReference
Routine vaccines

Make sure you are up-to-date on all routine vaccines before every trip — per the Swiss BAG schedule. These include:

BAG Impfplan
Cholera

Oral vaccination may be considered for high-risk travelers (humanitarian/healthcare work, prolonged stays in areas with poor sanitation or active outbreaks).

CDC Yellow Book
Hepatitis A

Recommended for all travelers. Note for Swiss travelers: Hepatitis A is not part of the routine Swiss BAG childhood schedule, so most adult travelers will need vaccination.

CDC Yellow Book
Hepatitis B

Recommended for unvaccinated travelers. Routine in the Swiss childhood schedule since 1998, so younger travelers are usually covered; older travelers should check their status.

CDC Yellow Book
Rabies

Rabid dogs are common in Equatorial Guinea and post-exposure treatment can be hard to obtain. Pre-exposure vaccination is recommended for long stays, remote travel, cyclists/bikers, animal workers, and young children.

CDC Yellow Book
Typhoid

Recommended for most travelers given widespread food and water exposure, especially those visiting rural areas, staying with friends or relatives, or on longer trips.

CDC Yellow Book
Yellow fever

Medically recommended for all travelers ≥9 months; a certificate is required if arriving from a YF-risk country. Single dose gives lifelong protection; give ≥10 days before arrival. In Switzerland, available only at approved yellow-fever vaccination centres.

Disease-specific guidance

Malaria

High

High risk in all areas year-round, including Bioko Island and the mainland (Río Muni). P. falciparum predominates and is chloroquine-resistant. Continuous antimalarial chemoprophylaxis (atovaquone-proguanil, doxycycline, mefloquine, or tafenoquine) is recommended for all travelers, combined with strict mosquito-bite prevention.

Risk
High, all areas, year-round
Species
Mainly P. falciparum
Resistance
Chloroquine-resistant
Prevention
Chemoprophylaxis + bite protection for all travelers

Yellow fever

High

Equatorial Guinea is in the yellow-fever endemic zone and the vaccine is medically recommended for all travelers ≥9 months. A certificate is required only when arriving from a YF-risk country. Vaccinate at least 10 days before arrival; see the country alert above.

Risk
Endemic (vaccine recommended)
Entry rule
Certificate if from YF-risk country
Timing
≥10 days before arrival
Yellow fever vaccine recommendation areas in Africa (CDC).

Dengue

Low

Dengue is present and transmitted by daytime-biting Aedes mosquitoes. Daytime mosquito-bite prevention (repellent, covering clothing) is the main protection; this also reduces other arboviral risks.

Distribution
Present countrywide
Mosquito
Aedes — bites during daytime
Prevention
Daytime bite protection

General prevention

Food & water

Strict food and water precautions are essential. Use bottled or treated water, avoid ice and raw produce, and eat only thoroughly cooked food. These measures reduce traveler's diarrhea, hepatitis A, and typhoid. Avoid wading or swimming in fresh water (schistosomiasis risk).

Mosquito protection

Aggressive mosquito-bite prevention is essential — chloroquine-resistant malaria risk is high year-round and country-wide, and antimalarial prophylaxis is recommended for all travelers. Dengue is also present. Use DEET or picaridin repellent, cover up, and sleep under an insecticide-treated net.
