Health
Iceland is generally low-risk for travelers. Tap water is safe and widely drinkable; normal food hygiene is usually sufficient. There is no malaria or yellow-fever risk. Mosquitoes are not established, but midges/flies and occasional ticks can bite outdoors. Usual trips have little altitude risk; prepare instead for fast-changing cold, wind, UV glare, geothermal burns, rough seas/sneaker waves, and limited services in highlands.
Vaccinations
Consult a doctor or travel clinic before travel. CDC advises being up to date on routine vaccines, including MMR, flu, polio, varicella, Tdap/Td and shingles as applicable, plus COVID-19. Hepatitis A may be considered for most travelers, especially rural/smaller-town or street-food exposure; hepatitis B is recommended for unvaccinated travelers. Rabies is uncommon in dogs, but pre-exposure vaccine may be discussed for animal/bat or remote work. Yellow-fever vaccine/certificate is not required for Iceland.
eSIM / connectivity
eSIM is practical for Iceland if your phone is unlocked and eSIM-compatible; international travel eSIMs commonly roam on Icelandic 4G/5G networks. Main local carriers are Síminn, Nova and Sýn. Coverage is strong around towns and main roads but can drop in highlands/remote coasts. Local tourist data options include prepaid SIM/data from carriers; Sýn also lists traveler connectivity and an Icelandair onboard starter pack. Check current eSIM versus physical-SIM availability before arrival.
