Yellow fever — vaccine strongly recommended; certificate required from risk countries

Liberia is in the yellow fever endemic zone and vaccination is recommended for all travelers ≥9 months for personal protection. A vaccination certificate is required for travelers arriving from a country with yellow fever transmission risk. The vaccine must be given at least 10 days before arrival; carry the international certificate (carnet jaune).

Lassa fever, Ebola history, and mpox

Lassa fever is endemic in Liberia (spread via food or surfaces contaminated by infected rodents), and the country had major Ebola transmission during the 2014–2016 West African outbreak. A clade II mpox outbreak is also ongoing (CDC Level 2). Avoid contact with rodents, bushmeat, and sick people; standard travelers are at low risk, while health and aid workers should take specific precautions.

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

Consider for aid/health workers, those staying in areas with poor sanitation or active outbreaks, or with individual risk factors. Oral vaccine (Dukoral) per EKRM guidance.

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

Consider per individual risk and stay duration. Routine in Swiss childhood schedule since 1998 — younger travelers usually covered.

CDC Yellow Book

Rabies

Recommended for longer stays, remote travel with limited medical access, cyclists/motorcyclists, children, and anyone working with animals. Post-exposure rabies immunoglobulin is often unavailable locally, which strengthens the case for pre-exposure vaccination.

CDC Yellow Book

Typhoid

Recommended for essentially all travelers given high exposure through food and water, particularly outside major hotels, in rural areas, or when visiting friends and relatives.

CDC Yellow Book

Yellow fever

Recommended for all travelers ≥9 months (endemic country); certificate required when arriving from a YF-risk country. Give at least 10 days before travel at a Swiss-approved YF center; carry the international certificate.

CDC Yellow Book

Disease-specific guidance

Malaria

High

High 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

About malaria CDC details

Yellow fever

High

Liberia is in the yellow fever endemic zone, and vaccination is medically recommended for all travelers ≥9 months. A certificate is required for travelers arriving from a country with YF transmission risk. Vaccinate at least 10 days before travel and carry the international certificate.

Status: Endemic — vaccine recommended
Entry rule: Required from YF-risk countries
Timing: ≥10 days before arrival

About yellow fever CDC details

Dengue

Moderate

Dengue is present in Liberia, 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

About dengue CDC details

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.
