Health
Bolivia ranges from Amazon lowlands to very high Andean cities, so plan by itinerary. Use safe food and water habits; avoid untreated freshwater where sanitation is uncertain. La Paz/El Alto, Lake Titicaca and Uyuni routes can trigger altitude illness: ascend gradually, hydrate, limit alcohol and build in rest. In lowland areas, prevent mosquito/sand-fly bites; CDC notes dengue, Zika, leishmaniasis and a 2026 chikungunya outbreak in Santa Cruz and Cochabamba. Heat, strong UV and cold nights can all be issues.
Vaccinations
Before travel, consult a doctor or travel clinic, ideally at least a month ahead. Be up to date on routine vaccines such as MMR, polio, tetanus/diphtheria/pertussis, flu, varicella, shingles as applicable, plus COVID-19. CDC recommends hepatitis A for unvaccinated travelers, hepatitis B for many travelers, typhoid for most travelers, and rabies pre-exposure discussion for higher-risk or remote trips. Malaria prevention may be advised for areas below 2,500 m, but not La Paz. Yellow fever vaccine is recommended for specified low-elevation areas east of the Andes; Bolivia requires proof of yellow-fever vaccination for arriving travelers age 1+. Confirm current entry rules with official sources before departure.
eSIM / connectivity
eSIM is supported, but setup is more local-carrier/in-store than fully tourist-packaged. Entel lists eSIM for prepaid and postpaid mobile lines, activated through Multicentros or executives nationwide, with a compatible phone, Wi-Fi, email for the QR code and registered IMEI. Tigo and Viva are major mobile operators; Tigo sells prepaid data bundles, while official tourist-specific eSIM information is not consistently published. If you need data immediately on arrival, consider an international travel eSIM, then compare local prepaid bundles in city carrier shops.
