Travel Health Guide: South Korea — Japanese Encephalitis, Vivax Malaria Near the DMZ, SFTS Ticks, and What Most US Travelers Get Wrong

Travel Health Guide: South Korea

Most US travelers heading to Seoul, Busan, or Jeju will need very little beyond their routine vaccines and a few smart food and water habits. South Korea is one of the safer destinations in Asia from an infectious disease standpoint: tap water in major cities is chlorinated and treated, the country was certified malaria-free in 1979 and re-eliminated it in tourist regions, and hospital quality in Seoul rivals anywhere in the world. That said, three risks catch travelers off guard every year. First, vivax malaria persists in a small zone along the Demilitarized Zone (DMZ) in northern Gyeonggi and Gangwon provinces, and the Korea Disease Control and Prevention Agency raised a nationwide malaria warning in August 2025 after detecting infected mosquitoes. Second, Japanese encephalitis virus still circulates in rural rice-paddy areas during summer and early fall, even though South Korea's national vaccination program has driven domestic cases down by more than 95% since the 1980s. Third, ticks carrying Severe Fever with Thrombocytopenia Syndrome (SFTS) virus, which has an 18% case-fatality rate, are active April through November in the countryside. The CDC reports about 1.3 million US travelers visit South Korea annually, and the vast majority finish their trips with nothing more than a sore lower back from low Korean BBQ tables. As an ER physician who has treated returning travelers, this guide will tell you exactly which vaccines you actually need, which prescription medications to consider, and which precautions are honest medical advice versus internet noise.

Quick Facts: South Korea Travel Health

• Region: East Asia
• US travelers per year: roughly 1.3 million (Korea Tourism Organization data, 2024)
• CDC Yellow Book risk level: low to moderate, varies sharply by itinerary
• Yellow fever entry requirement: none (only if arriving from a yellow-fever endemic country)
• Key health risks: traveler's diarrhea, Japanese encephalitis (rural, summer-fall), vivax malaria (DMZ region only), SFTS and other tick-borne illness (rural, April to November), hantavirus (HFRS, rural, autumn peak), air quality and yellow dust (March to May), heat illness (July-August), motor vehicle injury
• Recommended vaccines: routine immunizations up to date plus hepatitis A for most travelers; hepatitis B, typhoid, Japanese encephalitis, and rabies based on itinerary
• Prescription medications to consider: traveler's diarrhea antibiotics, motion sickness meds, anti-nausea, sleep aid for jet lag; malaria prophylaxis only for long-stay travel to DMZ border areas
• Travel insurance: recommended, especially if including hiking, skiing in Pyeongchang, or trips beyond Seoul

Overview: What South Korea Looks Like From a Travel Medicine Perspective

South Korea sits in a strange spot on the global travel health map. It is an OECD country with universal healthcare, world-class hospitals in Seoul and Busan, safe municipal water in cities, and one of the highest life expectancies on earth. From that angle it feels almost like traveling within Europe. But the country also borders North Korea, sits in a Japanese encephalitis-endemic zone, has emerging tick-borne disease that did not exist in the medical literature 15 years ago, and experiences seasonal yellow dust from the Gobi Desert that pushes Seoul's air quality into the unhealthy range several times each spring.

In my emergency medicine practice, the South Korea-related visits I see are not exotic tropical illnesses. They are almost always: traveler's diarrhea from street food in markets like Gwangjang or Myeongdong, dehydration and heat exhaustion in July-August humidity, sunburns in Busan and Jeju, sprained ankles from Bukhansan or Hallasan hiking, and respiratory complaints during yellow dust season. Occasionally I see a returning traveler with a fever after a long-stay assignment near the DMZ. Almost never do I see a US tourist returning from a one or two-week Seoul-Busan-Jeju trip with anything that required Wandr or a travel clinic.

That is the honest framing for South Korea: the medical risk for most US travelers is low, but a handful of itineraries change that calculation meaningfully. The rest of this guide walks through those itineraries.

Vaccines for South Korea: What You Actually Need

South Korea has no legal vaccine entry requirements for US travelers. The yellow fever certificate requirement only applies if you are arriving from a country with active yellow fever transmission, which the US is not. Everything below is a medical recommendation from the CDC's Travelers' Health page for South Korea, not a border requirement.

Routine vaccines: bring these up to date first

Before any travel vaccine conversation, your routine immunizations matter more than the exotic ones. Make sure these are current:

• MMR (measles, mumps, rubella): Two-dose series for adults born after 1957. Measles cases are rising globally in 2025-2026, including in South Korea, and unprotected travelers have brought it home repeatedly. If you cannot find your MMR record, your physician can either repeat the series or order a titer.
• Tdap (tetanus, diphtheria, pertussis): Booster every 10 years for tetanus, plus one lifetime Tdap dose in adulthood.
• Annual influenza: Korean winter flu season runs December through March and tracks the US season.
• COVID-19: Latest booster per current CDC guidance.
• Polio: A one-time adult booster is reasonable if your last dose was decades ago, though South Korea is not high-risk.

Hepatitis A: recommended for most travelers

Hepatitis A is the single most common vaccine-preventable disease in international travel. The CDC recommends the hepatitis A vaccine for almost all unvaccinated travelers to South Korea, because the virus spreads through contaminated food and water, and even hygienic-looking restaurants can have an infected food handler. A single pre-departure dose of the hepatitis A vaccine provides about 95% protection, and the two-dose series gives lifetime protection. If you are not already immune, get this one.

"Hepatitis A is the vaccine I rarely regret recommending. The clinical course is miserable, the vaccine is two shots over six months, and a single pre-departure dose is roughly 95% effective. There is no downside." — Alec Freling, MD

Hepatitis B: recommended for most adults regardless of trip

Hepatitis B is part of the routine US childhood schedule since 1991, but many adults born before then never received it. The vaccine is recommended for unvaccinated travelers to South Korea, especially anyone who might receive medical or dental care, get a tattoo, get acupuncture, or have new sexual partners. The three-dose series takes six months for full protection, but partial protection from one or two doses is meaningful.

Typhoid: selective, based on itinerary

Typhoid risk is low in modern South Korea. The vaccine is mainly recommended for:

• Long-stay travelers (more than 30 days)
• Visitors going to smaller cities or rural areas
• Adventurous eaters at markets, food stalls, and family-run restaurants outside the tourist zones

For a standard Seoul-Busan-Jeju itinerary staying in mid-range hotels and eating at restaurants, most travelers can skip typhoid. For a deeper itinerary that includes rural Jeolla or Gangwon homestays, street food tours, and temple stays, typhoid is reasonable.

Japanese encephalitis: selective, based on rural exposure in summer-fall

Japanese encephalitis (JE) is a mosquito-borne brain infection with a roughly 30% case-fatality rate and a high rate of permanent neurologic damage among survivors. South Korea is an endemic country, but the national vaccination program and improved living conditions have cut domestic cases dramatically since the 1980s. The remaining risk is primarily for:

• Travelers spending one month or more in the country, especially in rural areas
• Short-term travelers with significant rural exposure in summer or early fall, such as rice-paddy hikes, farm stays, or extended camping
• Frequent business travelers to JE-endemic regions of Asia

The JE vaccine (IXIARO) is a two-dose series given 28 days apart, with the last dose at least one week before travel. Adults 18 to 65 can compress the schedule to 7 days apart if needed. For a one-week Seoul-Busan trip in winter, the CDC does not recommend the JE vaccine. For a three-week summer trip including farm stays in rural Gangwon, it is worth getting.

Rabies: selective, for high-risk activities

South Korea has eliminated canine rabies, with the last confirmed human case decades ago. However, bat rabies and wildlife rabies still exist. Pre-exposure rabies vaccination is reasonable for:

• Travelers planning extensive rural cycling or hiking trips, especially in border provinces
• Anyone working with animals (veterinary students, researchers, wildlife volunteers)
• Long-stay travelers with rural exposure
• Children, who are more likely to approach animals and less likely to report a bite

If you are bitten or scratched by any mammal in South Korea, wash the wound thoroughly with soap and water for 15 minutes and seek medical care immediately for post-exposure prophylaxis. Major hospitals in Seoul and Busan stock rabies vaccine.

Cholera, meningococcal, yellow fever: not routinely needed

These are not recommended for standard South Korea travel.

Prescription Medications for South Korea

This is where Wandr's prescription workflow becomes useful. Our clinicians review your destination and call the prescriptions in to your local pharmacy for pickup before you fly.

Traveler's diarrhea antibiotics: yes, even though water is mostly safe

The official line is that tap water in South Korean cities is chlorinated and meets WHO drinking water standards. The practical line is that many Korean residents still drink bottled or filtered water by preference, and the food safety profile of street markets, raw seafood (hwe), and unfamiliar fermented foods (banchan that has sat out in cafes) creates real risk for the first-time visitor's gut.

Across all destinations, US travelers have roughly a 30 to 70% chance of developing traveler's diarrhea on a typical international trip, depending on the destination. For South Korea the rate sits in the lower end of that range, likely around 15 to 25%, but it is not zero. A standby prescription means you do not lose two days of your trip trying to find a pharmacist who speaks English at 3 AM.

The most useful prescription is a course of antibiotic (typically azithromycin in Asia given resistance patterns for ciprofloxacin in some regions), paired with anti-motility medication (loperamide). Take the antibiotic if you have fever, blood in stool, or symptoms not improving after 24 hours.

→ Pick up your traveler's diarrhea kit before you fly. Read our physician's comparison of Cipro vs azithromycin for the details on why we usually prescribe azithromycin for Asia travel.

Motion sickness and jet lag: probably yes

South Korea is one of the longest commercial flights from the continental US: typically 13 to 15 hours from the East Coast, 11 to 14 from the West Coast. Two prescriptions worth considering:

• Sleep aid for the overnight flight and the first 1-2 nights. Helps you reset to Korea Standard Time (UTC+9) faster. Avoiding 14 to 16 hours of jet lag-driven brain fog is worth the modest cost.
• Motion sickness medication. Useful if you are doing ferry trips to Jeju, Ulleungdo, or the southern islands, and for tour buses on the winding roads of Seoraksan and Jirisan national parks. Scopolamine patches work for 72 hours and are typically the most effective option for boat travel.

Read our physician's guide to jet lag for evidence-based timing strategies that pair with the medication.

Malaria prophylaxis: only for specific DMZ border itineraries

This is the area where official guidance and travel-clinic-marketing diverge most sharply.

The honest, evidence-based answer: the vast majority of US travelers to South Korea do not need malaria pills. The country was certified malaria-free by the WHO in 1979, then experienced re-emergence of vivax malaria in the 1990s along the border with North Korea. As of 2025, the Korea Disease Control and Prevention Agency reported ongoing low-level transmission concentrated in Paju, Yeoncheon, and Gimpo (northern Gyeonggi), and Cheorwon and parts of Gangwon, with cases mainly in Korean military personnel and farmers near the DMZ. The KDCA raised a nationwide malaria warning on August 19, 2025, after detecting the year's first infected mosquito.

Even with that warning in place, no major public health authority recommends malaria prophylaxis for short-term tourists visiting Seoul, Busan, Jeju, Incheon, or the standard tourist routes, including most day trips to the DMZ such as the Joint Security Area tour. The CDC describes the risk as too low to justify the side effects of weekly or daily antimalarials for short-stay tourist itineraries.

Cases where prophylaxis is worth considering:

• Long-stay assignments (more than one month) in Paju, Yeoncheon, Cheorwon, or other identified high-risk villages
• Military or government travelers with extended border-area duty
• Multi-week summer hiking trips in Gangwon's border zone

For these specific itineraries, atovaquone-proguanil (Malarone) is typically the cleanest choice. Read more in our physician's guide to "Do I Need Malaria Pills?" and the Malaria Prevention Complete Guide.

"I see this confusion in clinic constantly. People hear 'malaria in Korea' and want a prescription before a four-day Seoul trip. The risk for that itinerary is so close to zero that the side effect profile of the pills is the bigger problem. Save the prescription for the itineraries that actually need it." — Alec Freling, MD

Allergy meds and a small kit

A standard travel kit for South Korea: oral antihistamine (Korean spring tree pollen is significant), saline nasal spray (helpful during yellow dust days), oral rehydration salts, ibuprofen or acetaminophen, blister care, and any chronic medications in original packaging with copies of prescriptions. Note that South Korea has strict drug import laws: codeine-containing combinations and certain ADHD stimulants require advance approval. Check the Korean Ministry of Food and Drug Safety guidance before flying with controlled medications.

Mosquito-Borne Disease: Japanese Encephalitis and the DMZ Malaria Zone

Japanese encephalitis: rural, summer, evening exposure

JE is transmitted by Culex mosquitoes that breed in rice paddies and feed at dusk and dawn. The risk is highest from June through October in southern South Korea and from July through September in the north. Even in endemic zones, your odds of catching JE on a short tourist itinerary are very low, the CDC estimates fewer than 1 case per 1 million short-term travelers, but the severity of the disease means avoidance still matters.

Prevention regardless of vaccination status:

• DEET 25 to 30% or picaridin 20% insect repellent during dusk and dawn
• Long sleeves and pants in rural areas in summer
• Permethrin-treated clothing for camping or extended outdoor exposure
• Air conditioning or screened/netted sleeping quarters

Vivax malaria along the DMZ

The strain of malaria circulating in South Korea is Plasmodium vivax, not the more dangerous P. falciparum found in sub-Saharan Africa. Vivax tends to cause less severe acute disease but can produce relapsing illness from dormant liver-stage parasites months after the original exposure. Symptoms include high fever, chills, sweats, headache, body aches, and fatigue.

If you develop a fever within 12 months of returning from a trip that included DMZ-area exposure, tell your physician immediately and mention South Korea travel by name. Vivax malaria does not always show up on the first rapid diagnostic test, and US emergency departments may not have it in their differential without prompting.

Aedes mosquitoes and dengue: mostly imported, watch this trend

Imported dengue cases have appeared in South Korean travelers returning from Southeast Asia, but local transmission of dengue, Zika, or chikungunya within South Korea has been historically rare. Climate trends and the expansion of Aedes mosquito habitat northward are creeping the risk upward. As of 2026, the practical message is: no special precautions in South Korea, but apply the same mosquito-bite prevention if you are traveling onward from Korea to Thailand, the Philippines, or Vietnam.

Tick-Borne Disease: SFTS and Lyme

Tick-borne disease in South Korea is the underappreciated risk for travelers doing rural hiking or outdoor work. Two of note:

Severe Fever with Thrombocytopenia Syndrome (SFTS)

SFTS is caused by a bunyavirus transmitted by Haemaphysalis longicornis (the long-horned tick) and a few other species. South Korea reported its first human SFTS case in 2013. As of 2025, the case-fatality rate is roughly 18%, there is no vaccine, and no specific antiviral treatment. Cases occur April through November, peak in summer and early fall, and concentrate in rural farming, hiking, and herb-gathering activities. There have also been documented cases of person-to-person transmission and one case of dog-to-human transmission via bite.

Tick-borne encephalitis and Lyme

Tick-borne encephalitis virus and Borrelia (Lyme) have been detected in Korean ticks at low rates. Risk is meaningfully lower than central Europe but not zero for travelers doing extended rural exposure.

Practical prevention

• DEET or picaridin repellent on skin during rural activity
• Permethrin-treated socks, pants, and hiking boots
• Tuck pants into socks during forest and field hiking
• Full body tick check after every rural day, including scalp, behind ears, behind knees, groin, and armpits
• Stay on marked trails in Bukhansan, Seoraksan, Jirisan, and Hallasan
• Remove embedded ticks with fine-tipped tweezers, grasping close to the skin, pulling straight up without twisting
• See a physician promptly for fever, rash, severe headache, or flu-like illness within four weeks of a tick bite

Hantavirus (HFRS): The Autumn Rural Risk

Hemorrhagic fever with renal syndrome (HFRS) is caused by hantaviruses carried by field rodents, particularly the striped field mouse (Apodemus agrarius) and the Korean field mouse. Humans inhale aerosolized rodent urine or droppings, most often during outdoor work or recreation in fields, barns, and abandoned rural buildings.

South Korea reports about 400 HFRS cases per year, with a mortality rate of 1 to 4%. Cases peak from October to December and again from May to July, tracking rodent activity around agricultural cycles. Travelers at meaningful risk are those doing rural hiking, farm stays, military exercises, or outdoor camping during peak seasons. Standard urban and beach tourism in Seoul, Busan, or Jeju does not carry meaningful HFRS risk.

Prevention is environmental: avoid sleeping on bare ground in fields, do not handle dead rodents, keep food sealed during rural camping, and avoid stirring up dust in barns or rural sheds. A Korean-made hantavirus vaccine (Hantavax) exists and is used in the Korean military, but it is not routinely available or recommended for US tourists.

Air Quality, Yellow Dust, and Heat

Yellow dust season (March to May)

Each spring, strong westerly winds carry mineral dust from the Gobi Desert and northern China across the Korean peninsula. These episodes layer onto the existing PM2.5 fine particulate pollution from regional industry and traffic. Seoul's annual average PM2.5 concentration in 2025 was about 17 µg/m³, well below the worst global cities but more than double the World Health Organization's annual guideline of 5 µg/m³. On bad yellow dust days, particulate levels can spike into the 100 to 200 µg/m³ range.

Practical advice:

• Check daily air quality on the AirKorea app or IQAir before outdoor activity
• Wear a KF94 mask (Korea's equivalent of an N95) on days the AQI exceeds 100; pharmacies sell these in every Seoul neighborhood
• People with asthma or COPD should travel with inhalers and a written rescue plan
• Limit strenuous outdoor exercise on yellow dust alert days
• Keep windows closed and use HEPA air purifiers in your accommodation if sensitive

Summer heat (July to August)

Seoul summer humidity routinely climbs above 80% with temperatures of 32 to 35°C (90 to 95°F). Heat illness is one of the more common medical issues I see in tourists in this window, especially during walking-heavy palace itineraries and outdoor markets.

Drink water before you feel thirsty, take indoor breaks in air-conditioned cafes every couple of hours, wear breathable clothing, and use a cooling towel or portable fan. If you develop dizziness, confusion, weakness, nausea, or a body temperature above 39°C (102°F), seek medical care immediately.

Winter cold (December to February)

Korean winters are dry, windy, and frequently sub-freezing in the north. Frostbite is rare for tourists but not unheard of among heavy drinkers on Hongdae nights. Layer appropriately and treat alcohol-heavy nights with the respect they deserve.

Food and Water Safety in South Korea

Tap water in major South Korean cities is chlorinated and treated to internationally recognized standards. The Environmental Performance Index has historically ranked South Korea's water quality in the global top 25. Many Korean residents still prefer bottled or filtered water out of habit and taste preference rather than safety concern.

Practical guidance:

• Tap water is safe to drink in Seoul, Busan, Incheon, and other major cities
• In rural areas, ask your accommodation host or default to bottled water
• Ice in established restaurants is safe; street stalls in markets are typically also fine in Korea but caution scales with how confident the operation looks
• Raw seafood (hwe) is a Korean cultural staple. Reputable hwe restaurants are generally safe but the risk of Vibrio infection and parasites is non-zero. Pregnant travelers and immunocompromised travelers should skip raw seafood
• Fermented banchan that has been left out for hours at room temperature in casual cafes is a more common source of mild traveler's diarrhea than raw fish
• Street food in busy, high-turnover markets (Gwangjang, Myeongdong, Namdaemun) is generally safe because items are cooked to order and turnover is fast

Travel Insurance for South Korea

South Korea has world-class hospital infrastructure, with Joint Commission International-accredited facilities in Seoul and Busan including Severance Hospital, Asan Medical Center, and Samsung Medical Center. Care is excellent, but as a US visitor you will pay out of pocket and seek reimbursement after. A skiing accident in Pyeongchang, a hiking injury on Bukhansan, or a hospital admission for severe traveler's diarrhea can cost thousands of dollars without coverage.

I recommend travel medical insurance with at least $100,000 of medical coverage and emergency evacuation for any South Korea trip, especially for older travelers, anyone with chronic conditions, anyone hiking or skiing, and anyone traveling with children. Read our physician's guide to travel insurance for the details on what to look for in a policy.

→ Get travel insurance through Wandr in the same flow as your vaccines and prescriptions.

Region-by-Region Health Considerations

Seoul and Greater Seoul (Gyeonggi)

The lowest-risk region for nearly every infectious disease except hantavirus in late autumn agricultural areas at the metro's edge. Yellow dust and PM2.5 are the dominant health considerations from March through May. Heat illness in July and August.

DMZ and Border Areas (northern Gyeonggi, Gangwon)

The only South Korean region with a malaria warning. Day tours to the JSA from Seoul carry minimal risk because exposure time and itineraries are short and travelers stay in vehicles or visitor facilities. Longer stays or multi-week itineraries in Paju, Yeoncheon, Cheorwon, or rural Gangwon border villages warrant a conversation about malaria prophylaxis. Tick and JE risk also higher in this zone in summer.

Busan and Southern Coast

Beach destination with similar profile to Seoul plus higher seasonal heat illness risk and a slightly higher seafood-related GI risk if you partake heavily in hwe.

Jeju Island

Subtropical climate, generally low infectious disease risk, and the country's mildest weather. Hallasan hiking carries the standard hiking risks (sprains, dehydration, falls). Hantaan virus has been documented on Jeju but at low rates for tourists.

Jeolla and Gyeongsang Rural Areas

The highest-risk regions for SFTS ticks, hantavirus during autumn, and Japanese encephalitis during summer. Pretty much only relevant to travelers doing rural hiking, farm stays, temple stays, or extended outdoor work.

Gangwon (Pyeongchang, Sokcho, Seoraksan)

Skiing in Pyeongchang means cold injury risk. Altitude is modest: Hallasan and Bukhansan summits are below 2,000 meters, so acute mountain sickness is not a meaningful concern. Tick risk in summer hiking. Border areas to the north of Gangwon enter the DMZ malaria zone.

• US passport, visa-free entry under K-ETA for stays up to 90 days (check current K-ETA status before flying)

FAQ: South Korea Travel Health

Do I need any vaccines to enter South Korea from the US?

No. South Korea has no legal vaccine entry requirements for US travelers. The yellow fever requirement applies only if you are arriving from a country with active yellow fever transmission. CDC-recommended vaccines (routine plus hepatitis A for most travelers) are medical advice, not border policy.

Do I need malaria pills for a Seoul or Busan trip?

No. Vivax malaria in South Korea is concentrated along the border with North Korea in northern Gyeonggi and Gangwon provinces, and the risk to short-term Seoul, Busan, or Jeju tourists is essentially zero. Prophylaxis is only recommended for long-stay travelers or extended outdoor itineraries in identified DMZ-area high-risk villages.

Is the tap water safe to drink in South Korea?

Yes in major cities. Seoul, Busan, Incheon, and other large cities chlorinate and treat municipal water to WHO standards. Many Korean residents still prefer filtered or bottled water by habit and taste, not safety. In rural areas, default to bottled or filtered water.

What is yellow dust and do I need a mask for it?

Yellow dust is mineral dust transported by westerly winds from the Gobi Desert and northern China each spring, March through May. On heavy yellow dust days, PM2.5 levels in Seoul can spike well above safe thresholds. A KF94 mask is recommended on days the AQI exceeds 100, and people with asthma or COPD should be especially cautious.

How long is the flight to South Korea and should I worry about DVT?

Direct flights from the US East Coast are 13 to 15 hours, West Coast 11 to 14 hours. Long-haul flights raise the risk of deep vein thrombosis, particularly for travelers with prior clots, certain medical conditions, or limited mobility. Read our physician's guide to DVT prevention on long flights.

Is Japanese encephalitis a real risk for tourists?

Low for typical tourist itineraries, higher for rural exposure in summer and early fall. The CDC estimates fewer than 1 case per 1 million short-term travelers. Vaccination is generally recommended for travelers staying more than a month, anyone with extended rural exposure during JE transmission season, or frequent regional business travelers.

What about the bird flu and other emerging respiratory diseases?

South Korea has reported periodic H5N1 detections in poultry, but human cases are rare. Avoid live bird markets, do not handle sick or dead birds, and follow standard respiratory hygiene. There is no special precaution required for tourists who are not in close contact with poultry.

Can I bring my US prescriptions into South Korea?

Most routine prescriptions are allowed in original packaging with documentation. Codeine-containing combinations and certain controlled substances including ADHD stimulants require advance approval from the Korean Ministry of Food and Drug Safety. Check current rules before flying with controlled medications and bring a doctor's letter.

Is South Korea safe for solo female travelers from a health perspective?

Yes. South Korea ranks among the safer countries globally for solo travel from both a violent crime and infectious disease standpoint. Standard precautions around alcohol, taxis, and personal items apply as anywhere.

What if I get sick in South Korea?

Major cities have JCI-accredited hospitals with English-speaking staff at international clinics within Severance, Asan, Samsung Medical Center, and Seoul National University Hospital. Pharmacies (약국) are widely available. The emergency number is 119, and the dedicated tourist helpline 1330 has 24/7 English-language assistance and can help direct you to appropriate care.

Pre-Trip Health Checklist for South Korea

• 4 to 8 weeks before departure: complete a Wandr pre-trip health check so a clinician can review your itinerary and any chronic conditions
• 4 to 6 weeks before: book hepatitis A and any other recommended vaccines through Wandr; if Japanese encephalitis vaccine is indicated, start the two-dose series now
• 2 to 4 weeks before: pick up traveler's diarrhea antibiotics and any other prescriptions from your local pharmacy
• 1 to 2 weeks before: confirm prescription supply, fill any travel-specific prescriptions, and finalize travel insurance
• 1 day before: print insurance card, embassy contact, hospital list, and confirmation of any K-ETA or visa documentation
