The information on these pages should be used to research health risks and to inform the pre-travel consultation. For advice regarding safety and security please check the UK Foreign and Commonwealth Office (FCO) website.
Travellers should ideally arrange an appointment with their health professional at least four to six weeks before travel. However, even if time is short, an appointment is still worthwhile. This appointment provides an opportunity to assess health risks taking into account a number of factors including destination, medical history, and planned activities. For those with pre-existing health problems, an earlier appointment is recommended.
All travellers should ensure they have adequate travel health insurance.
A list of useful resources including advice on how to reduce the risk of certain health problems is available below.
Details of vaccination recommendations and requirements are provided below.
Travellers should be up to date with routine vaccination courses and boosters as recommended in the UK. These vaccinations include for example measles-mumps-rubella (MMR) vaccine and diphtheria-tetanus-polio vaccine.
Country specific diphtheria recommendations are not provided here. Diphtheria tetanus and polio are combined in a single vaccine in the UK. Therefore, when a tetanus booster is recommended for travellers, diphtheria vaccine is also given. Should there be an outbreak of diphtheria in a country, diphtheria vaccination guidance will be provided where appropriate.
Those who may be at increased risk of an infectious disease due to their work, lifestyle choice, or certain underlying health problems should be up to date with additional recommended vaccines. See the individual chapters of the ‘Green Book’ Immunisation against infectious disease for further details.
There are no certificate requirements under International Health Regulations.
The vaccines in this section are recommended for most travellers visiting this country. Information on these vaccines can be found by clicking on the blue arrow. Vaccines are listed alphabetically.
Tetanus
Tetanus is caused by a toxin released from Clostridium tetani and occurs worldwide. Tetanus bacteria are present in soil and manure and may be introduced through open wounds such as a puncture wound, burn or scratch.
Travellers should thoroughly clean all wounds and seek appropriate medical attention.
Country specific information on medical facilities may be found in the ‘health’ section of the FCO foreign travel advice website.
The vaccines in this section are recommended for some travellers visiting this country. Information on when these vaccines should be considered can be found by clicking on the arrow. Vaccines are listed alphabetically.
Hepatitis B
Hepatitis B is a viral infection; it is transmitted by exposure to infected blood or body fluids. This mostly occurs during sexual contact or as a result of blood-to-blood contact (for example from contaminated equipment during medical and dental procedures, tattooing or body piercing procedures, and sharing of intravenous needles). Mothers with the virus can also transmit the infection to their baby during childbirth.
2% or more of the population are known or thought to be persistently infected with the hepatitis B virus (intermediate/high prevalence).
Travellers should avoid contact with blood or body fluids. This includes:
A sterile medical equipment kit may be helpful when travelling to resource poor areas.
Vaccination could be considered for all travellers, and is recommended for those whose activities or medical history put them at increased risk including:
Japanese Encephalitis (JE)
Japanese encephalitis (JE) is a viral infection transmitted to humans by the bite of an infected mosquito. These mosquitoes usually bite between dusk and dawn, mainly in rural areas; especially where there are rice fields, swamps and marshes. Mosquitoes become infected by biting JE infected animals (particularly pigs) or birds.
Travellers are at increased risk of infection when visiting rural areas. Short trips (usually less than a month) especially if only travelling to urban areas, are considered lower risk.
JE occurs in this country, transmission season is typically May to October. Cases may be reported outside these months. Vaccine is not routinely recommended for short trips to Seoul or major cities..
All travellers should avoid mosquito bites particularly between dusk and dawn.
Rabies
Rabies is a viral infection which is usually transmitted following contact with the saliva of an infected animal most often via a bite, scratch or lick to an open wound or mucous membrane (such as on the eye, nose or mouth). Although many different animals can transmit the virus, most cases follow a bite or scratch from an infected dog. In some parts of the world, bats are an important source of infection.
Rabies symptoms can take some time to develop, but when they do, the condition is almost always fatal.
The risk of exposure is increased by certain activities and length of stay (see below). Children are at increased risk as they are less likely to avoid contact with animals and to report a bite, scratch or lick.
Rabies is considered a risk and has been reported in domestic animals in this country. Bats may also carry rabies-like viruses.
A full course of pre-exposure vaccines simplifies and shortens the course of post-exposure treatment and removes the need for rabies immunoglobulin which is in short supply world-wide.
Pre-exposure vaccinations are recommended for travellers whose activities put them at increased risk including:
Tuberculosis (TB)
TB is a bacterial infection transmitted most commonly by inhaling respiratory droplets from an infectious person. This is usually following prolonged or frequent close contact.
The average annual incidence of TB is greater than or equal to 40 cases per 100,000 population (further details).
Travellers should avoid close contact with individuals known to have infectious pulmonary (lung) TB.
Those at risk during their work (such as healthcare workers) should take appropriate infection control precautions.
According to current national guidance, BCG vaccine should be recommended for those at increased risk of developing severe disease and/or of exposure to TB infection e.g. when the average annual incidence of TB is greater than or equal to 40 cases per 100,000 population. See Public Health England’s Immunisation against infectious disease, the ‘Green Book’.
For travellers, BCG vaccine is also recommended for:
There are specific contraindications associated with the BCG vaccine and health professionals must be trained to administer this vaccine intradermally (just under the top layer of skin).
Following administration, no further vaccines should be administered in the same limb for 3 months.
The BCG vaccine is given once only, booster doses are not recommended.
Malaria is a serious illness caused by infection of red blood cells with a parasite called Plasmodium. The disease is transmitted by mosquitoes which predominantly feed between dusk and dawn.
Symptoms usually begin with a fever (high temperature) of 38°C (100°F) or more. Other symptoms may include feeling cold and shivery, headache, nausea, vomiting and aching muscles. Symptoms may appear between eight days and one year after the infected mosquito bite.
Prompt diagnosis and treatment is required as people with malaria can deteriorate quickly. Those at higher risk of malaria, or of severe complications from malaria, include pregnant women, infants and young children, the elderly, travellers who do not have a functioning spleen and those visiting friends and relatives
Travellers should follow an ABCD guide to preventing malaria:
Awareness of the risk – Risk depends on the specific location, season of travel, length of stay, activities and type of accommodation.
Bite prevention – Travellers should take mosquito bite avoidance measures.
Chemoprophylaxis – Travellers should take antimalarials (malaria prevention tablets) if appropriate for the area (see below). No antimalarials are 100% effective but taking them in combination with mosquito bite avoidance measures will give substantial protection against malaria.
Diagnosis – Travellers who develop a fever of 38°C [100°F] or higher more than one week after being in a malaria risk area, or who develop any symptoms suggestive of malaria within a year of return should seek immediate medical care. Emergency standby treatment may be considered for those going to remote areas with limited access to medical attention.
There is a very low risk of malaria in the northern areas of South Korea, in Gangwon-do and Gyeonggi-do Provinces, and Incheon City (towards the Demilitarized Zone or DMZ): awareness of risk and bite avoidance recommended.
There are some risks that are relevant to all travellers regardless of destination. These may for example include road traffic and other accidents, diseases transmitted by insects or ticks, diseases transmitted by contaminated food and water, sexually transmitted infections, or health issues related to the heat or cold. Some additional risks (which may be present in all or part of this country) are mentioned below and are presented alphabetically.
Insect or tick bites can cause irritation and infections of the skin at the site of a bite. They can also spread certain diseases.
There is a risk of insect or tick-borne diseases in some areas of Eastern Asia. This includes diseases such as chikungunya, Crimean-Congo haemorrhagic fever, leishmaniasis and scrub typhus.
Further information about specific insect or tick-borne diseases for this country can be found, if appropriate on this page, in other sections of the country information pages and the insect and tick bite avoidance factsheet.
Human cases of Tick-borne encephalitis (TBE) for this country are unknown, but there is some evidence that there is a possible risk.
Tick-borne encephalitis (TBE) is a viral infection transmitted by the bite of infected ticks. Less commonly, cases of TBE occur following ingestion of unpasteurised milk products.
Travellers are at increased risk of exposure during outdoor activities in areas of vegetation (gardens, parks, meadows, forest fringes and glades). Ticks are usually most active between early spring and late autumn.
