Yellow fever vaccination certificate required for entry
Guinea requires proof of yellow fever vaccination for all arriving travelers aged 9 months and older — the certificate is checked at Ahmed Sékou Touré International Airport in Conakry. The vaccine must be given at least 10 days before arrival to be valid. Swiss travelers must receive it at an approved yellow fever vaccination center and carry the international certificate (carnet jaune).

Lassa fever and viral hemorrhagic fevers
Lassa fever is endemic in Guinea (spread via contact with food or surfaces contaminated by infected rodents). Guinea also has a history of Ebola outbreaks. Avoid contact with rodents, sick people, and bushmeat. Standard travelers are at low risk; healthcare and aid workers should take specific precautions.

Disease-specific guidance
Malaria
HighHigh risk throughout the entire country, year-round, with no low- or no-risk areas. The dominant parasite is chloroquine-resistant Plasmodium falciparum, the most dangerous form. Chemoprophylaxis is recommended for all travelers in addition to consistent mosquito-bite prevention.
- Risk area
- All regions, year-round
- Parasite
- Mainly P. falciparum (most dangerous)
- Resistance
- Chloroquine-resistant
- Prevention
- Chemoprophylaxis + mosquito protection
Yellow fever
HighGuinea is in the yellow fever endemic zone, and vaccination is medically recommended for all travelers ≥9 months. It is also required for entry — proof is checked on arrival in Conakry. Vaccinate at least 10 days before travel and carry the international certificate.
- Status
- Endemic — vaccine recommended
- Entry rule
- Certificate required for entry
- Timing
- ≥10 days before arrival
Dengue
ModerateDengue is present in Guinea, transmitted by daytime-biting Aedes mosquitoes. Risk is year-round in urban and rural areas. The same mosquito-bite prevention used for malaria also protects against dengue.
- Distribution
- Present nationwide
- Mosquito
- Aedes — bites during daytime
- Prevention
- Daytime repellent and covering clothing
General prevention
Food & water
Strict food and water precautions are essential — use bottled or properly treated water, avoid ice, and eat only thoroughly cooked, hot food. These measures reduce the risk of traveler's diarrhea, hepatitis A, typhoid, and cholera. Healthcare access is limited, so carry a personal medical kit including standby treatment for traveler's diarrhea.
Mosquito protection
Aggressive mosquito-bite prevention is essential and required year-round: malaria risk (chloroquine-resistant P. falciparum) is high across the entire country with no low-risk areas. Use DEET or picaridin repellent, sleep under an insecticide-treated net, and wear covering clothing. The same measures also protect against dengue, transmitted by daytime-biting Aedes mosquitoes.
