Health
Reference only, not medical advice. Use safe-water and food precautions: drink sealed/treated water, avoid ice of uncertain source, and eat food served hot. Mosquito-borne dengue, Zika, chikungunya and some malaria risk occur mainly in lower-elevation coastal/Amazon areas; Quito, Guayaquil and Galápagos have no CDC-listed malaria transmission. Use repellent, sleeves and screened/AC rooms. Quito is about 2,850 m and Andean hikes go higher, so plan time to acclimatize. Expect strong equatorial UV, heat/humidity on the coast/Amazon, and avoid unsafe freshwater after rains.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. Be current on routine vaccines such as MMR, polio, tetanus/diphtheria/pertussis, flu, varicella and COVID-19. CDC commonly recommends hepatitis A for unvaccinated travelers to Ecuador, hepatitis B for many travelers, and typhoid for most travelers, especially rural/smaller-city travel. Ask about rabies for animal or remote-area exposure and malaria prevention for risk provinces. Yellow fever vaccine is recommended for some areas east of the Andes below 2,300 m, not for Quito, Guayaquil or Galápagos-only trips; Ecuador requires proof for some travelers arriving from yellow-fever-risk countries/long layovers.
eSIM / connectivity
eSIM works in Ecuador on compatible unlocked phones, but travelers should not assume every local prepaid counter can issue one quickly. Major local networks are Claro, Movistar/Tigo and CNT; physical prepaid SIM/data packages remain the easiest local fallback, with shops in airports and cities. International travel eSIMs also sell Ecuador data plans and usually roam on local networks. Confirm coverage for Amazon, Galápagos and mountain routes, where service can be patchy.
