Korea is a genuinely easy, low-risk country to travel in healthwise — modern hospitals, good hygiene standards, and nothing exotic to worry about for most itineraries. A little preparation still goes a long way.
Vaccines
No vaccines are currently required for entry to South Korea from most countries. That said, it's worth a visit to a travel health provider or your regular doctor 4–6 weeks before you fly to check:
- Routine vaccines are up to date — MMR (measles, mumps, rubella), DTaP/Tdap, polio, and an annual flu shot. Measles in particular is worth confirming, since it's a common reason travellers get flagged at all internationally.
- Hepatitis A is commonly recommended for travellers to Korea, and Hepatitis B is sometimes discussed depending on your plans.
- Japanese encephalitis and rabies only tend to come up for specific situations — extended rural stays, a lot of hiking or camping, or working with animals — not a standard city-and-sightseeing trip.
- Malaria is a non-issue for almost every visitor: any risk is limited to rural parts of northern Incheon, Gangwon and Gyeonggi provinces near the DMZ, March–December. Seoul, Busan, Jeju and the standard tourist route are not malaria zones.
None of this is a reason to worry — it's just worth a quick doctor's visit rather than leaving it to the airport.
Tap water
Short answer: yes, it's safe in the cities. See the full drinking water guide for when to trust it straight from the tap and when to grab a bottle instead.
Travel insurance
Korean hospitals are excellent — modern, efficient, and used to treating a wide range of conditions — but they're not free, and as a foreign visitor you're expected to be able to pay for treatment yourself. Travel insurance that covers medical treatment and evacuation is genuinely worth having, not just a box to tick; a single ER visit or an overnight stay can add up fast without it. Keep your policy details and emergency number somewhere you can reach at 2am, not just buried in an email.
Pharmacies & medication
Pharmacies (약국, yakguk) are everywhere, easy to spot by a green cross sign, and pharmacists can often help with minor ailments directly without needing a doctor. If you take regular prescription medication, bring enough for your whole trip in its original packaging — some medications that are over-the-counter or common elsewhere (certain allergy, ADHD, and strong painkiller medications in particular) are restricted or require paperwork in Korea, so check before you fly rather than assuming.
Air quality
Korea has a genuine seasonal fine-dust (미세먼지) problem, worst in late winter and spring. It's rarely severe enough to change your plans, but if you have asthma or another respiratory condition, it's worth checking the daily air quality index (widely shown in weather apps and on NAVER) and keeping a mask handy on bad days — pharmacies and convenience stores sell proper KF94-rated masks everywhere.
If something does go wrong
See the staying safe guide for emergency numbers — 119 for ambulance/fire, 112 for police, and the 1330 Korea Travel Hotline for anything urgent that isn't life-threatening. All three offer English-language support.
