Yellow fever certificate required for risk areas
Bolivia requires proof of yellow fever vaccination for travellers age 1 year and older arriving who intend to visit a yellow-fever risk area (the lowlands below 2,300 m east of the Andes). Direct travellers staying only in La Paz, Sucre, or the high Altiplano are generally exempt, but carrying the certificate avoids problems. Allow at least 10 days between vaccination and travel for protection to develop.

Altitude illness — La Paz, Uyuni, Lake Titicaca
Much of Bolivia's tourist circuit sits very high: La Paz (~3,600 m), Uyuni salt flats (~3,650 m), and Lake Titicaca (~3,800 m). Acute mountain sickness is common on rapid ascent. Plan a gradual itinerary, allow acclimatisation days, and discuss acetazolamide prophylaxis with your travel medicine specialist. This is a non-infectious risk and is not prevented by any vaccine.

Chikungunya activity (Santa Cruz, Cochabamba)
The CDC has noted increased chikungunya transmission in the Santa Cruz and Cochabamba departments. Strict daytime mosquito-bite prevention is the main protection; vaccination may be discussed for some travellers (see below).

Disease-specific guidance
Malaria
ModerateMalaria occurs in all areas below 2,500 m, mainly in the Amazon lowlands of the north and east (Beni, Pando, and parts of Santa Cruz, La Paz, and Cochabamba). La Paz city and areas above 2,300 m are no-risk. Roughly 99% of cases are P. vivax with rare P. falciparum; parasites are chloroquine-resistant. Prophylaxis or standby treatment depends on the specific itinerary.
- Risk
- All areas <2,500 m
- Main areas
- Amazon lowlands: Beni, Pando, lowland Santa Cruz/La Paz/Cochabamba
- No risk
- La Paz city, >2,300 m (Altiplano)
- Species
- ~99% P. vivax, rare P. falciparum (chloroquine-resistant)
- Prophylaxis
- Atovaquone-proguanil, doxycycline, or mefloquine
Yellow fever
ModerateYellow fever is endemic in Bolivia's lowlands east of the Andes below 2,300 m — Beni, Pando, Santa Cruz, and designated areas of Chuquisaca, Cochabamba, La Paz, and Tarija. La Paz city, Sucre, and the high Altiplano are no-risk. Vaccination is recommended for the risk areas and a certificate is required for travellers heading there.
- Vaccine
- Single dose, lifelong protection
- Timing
- ≥10 days before travel
- Recommended
- Lowlands <2,300 m east of Andes
- Risk depts
- Beni, Pando, Santa Cruz; parts of Chuquisaca, Cochabamba, La Paz, Tarija
- Not needed
- La Paz city, Sucre, >2,300 m
- Entry rule
- Certificate required for risk-area travel (age 1+)
Dengue
ModerateDengue is endemic in the lowlands with year-round transmission and rainy-season peaks; risk is concentrated in Santa Cruz and the tropical east and north. Daytime mosquito-bite prevention is the main protection for every traveler heading below 2,000 m.
- Distribution
- Lowlands; Santa Cruz, tropical east/north
- Vector
- Aedes aegypti — daytime biter
- Season
- Year-round; peaks in the rainy season
Chikungunya
LowChikungunya circulates in the lowlands, with increased transmission noted in Santa Cruz and Cochabamba. Same daytime Aedes vector as dengue, so dengue prevention also protects against chikungunya. Joint pain can persist for months. Vaccination is considered in outbreak settings (see EKRM statement).
Zika
PresentZika is transmitted by daytime Aedes mosquitoes in the lowlands. Pregnancy and pre-conception planning are the key clinical concerns: pregnant women should avoid travel to risk areas, and couples should use condoms during travel and for 3 months after return.
General prevention
Food & water
Standard food and water precautions, particularly outside major cities and in the lowlands. Use bottled or filtered water for drinking and brushing teeth in rural regions and the Amazon basin. These precautions reduce traveler's diarrhea, hepatitis A, and typhoid risk.
Mosquito protection
Mosquito-bite prevention is essential below 2,500 m, where dengue, Zika, chikungunya, and malaria all occur. Daytime-biting Aedes mosquitoes (dengue, Zika, chikungunya) require day protection; Anopheles (malaria) bite from dusk into the night. Use DEET 30%+ or picaridin 20%, long sleeves at peak biting times, and screened or air-conditioned rooms. Permethrin-treated clothing for trips into the Amazon. No mosquito risk on the high Altiplano (La Paz, Uyuni, Lake Titicaca).
