Health
Samoa is tropical, warm and humid year-round; heat, sun and dehydration are practical risks, especially during active days. Use safe-food habits, drink bottled/boiled/filtered water, and be cautious with ice, raw seafood, salads and street barbecue. Dengue and Zika risk exist; use repellent, covered clothing and screened/air-conditioned rooms. Malaria is not considered a problem. Avoid floodwater/freshwater exposure after heavy rain because leptospirosis is a risk.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. Be up to date on routine vaccines, including MMR, polio, Tdap, influenza, varicella and COVID-19 as applicable. CDC recommends hepatitis A and typhoid for many travelers, hepatitis B for unvaccinated travelers, and rabies only for higher-risk itineraries or limited access to care. Yellow-fever vaccine is not recommended for Samoa itself, but a certificate is required for travelers age 1+ arriving from, or transiting over 12 hours in, a yellow-fever-risk country.
eSIM / connectivity
Connectivity is generally workable on the main islands: Samoa Tourism lists Vodafone Samoa and Digicel as the main mobile providers, with 4G coverage across Upolu and Savai'i and prepaid SIMs available at Faleolo Airport and in Apia. eSIM is available but not universal; Vodafone Samoa sells an online prepaid eSIM that can be activated before arrival. Check device compatibility and keep a physical-SIM fallback for remote areas.
