Yellow fever entry rule — only if arriving from a risk country
Belize may require proof of yellow fever vaccination from travelers arriving from (or transiting) a country with risk of yellow fever transmission. There is no yellow fever risk within Belize itself, and travelers arriving directly from Switzerland are not affected. Confirm current requirements with your travel medicine specialist before departure.

Malaria-free certification
Belize was certified malaria-free by the WHO in 2023. Routine malaria chemoprophylaxis is generally no longer indicated for tourist travel; mosquito-bite protection remains the priority for dengue and other arboviruses. Discuss any rural or long-term itineraries with your travel medicine specialist.

Disease-specific guidance
Malaria
LowBelize was certified malaria-free by the WHO in 2023, so risk to travelers is now negligible. Historically transmission was confined to inland rural districts (Cayo, Stann Creek, Toledo), with Belize City, San Pedro/Ambergris Caye, and the cayes considered no-risk. Routine chemoprophylaxis is generally not indicated; mosquito-bite protection remains worthwhile.
- Status
- WHO-certified malaria-free (2023)
- Historic risk
- Inland rural districts (Cayo, Stann Creek, Toledo)
- No risk
- Belize City, San Pedro/Ambergris Caye, the cayes
- Prevention
- Mosquito protection; chemoprophylaxis generally not indicated
Yellow fever
NoneNo yellow fever risk in Belize. A vaccination certificate may be required only if arriving from or transiting a country with risk of yellow fever transmission. Direct travel from Switzerland is not affected.
Dengue
ModerateEndemic year-round throughout Belize, including coastal resort areas and the cayes, with peaks during the rainy season (roughly June–November). Daytime mosquito-bite prevention is the main protection.
- Distribution
- Nationwide incl. coast and cayes
- Season
- Year-round; peaks in rainy season (Jun–Nov)
- Mosquito
- Aedes aegypti — bites during daytime
Chikungunya
LowChikungunya circulates via the same daytime Aedes mosquito as dengue, so dengue prevention also protects against chikungunya. Vaccination is generally not recommended for routine travel but may be considered in outbreak settings (see EKRM statement).
Zika
PresentZika circulates in Belize via the same daytime Aedes mosquito as dengue. Because Zika infection in pregnancy can cause severe birth defects, pregnant travelers are generally advised to avoid non-essential travel, and couples planning pregnancy should follow current EKRM/CDC waiting-period advice after travel.
- Vector
- Aedes aegypti — daytime biting
- Pregnancy
- Avoid non-essential travel if pregnant
- Prevention
- Strict daytime bite protection; safe-sex precautions
General prevention
Food & water
Use bottled or filtered water, avoid ice from unverified sources, and pay attention to food hygiene. Standard tropical precautions reduce the risk of traveler's diarrhea, hepatitis A, and typhoid — especially relevant when eating outside major hotels and resorts. Avoid swimming in or swallowing fresh water (leptospirosis risk).
Mosquito protection
Year-round dengue, Zika, and chikungunya risk means daytime mosquito protection (DEET or picaridin repellent, long sleeves) is essential — including on the cayes and in San Pedro/Ambergris Caye. The same Aedes mosquito bites by day, so protection is needed beyond dawn and dusk. Zika is particularly relevant for pregnant travelers or those planning pregnancy.
