The information on these pages should be used to research health risks and to inform the pre-travel consultation.
Due to COVID-19, travel advice is subject to rapid change. Countries may change entry requirements and close their borders at very short notice. Travellers must ensure they check current Foreign, Commonwealth & Development Office (FCDO) travel advice in addition to the FCDO specific country page (where available) which provides additional information on travel restrictions and entry requirements in addition to safety and security advice.
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.
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.
Hepatitis A is a viral infection transmitted through contaminated food and water or by direct contact with an infectious person. Symptoms are often mild or absent in young children, but the disease becomes more serious with advancing age. Recovery can vary from weeks to months. Following hepatitis A illness immunity is lifelong.
Those at increased risk include travellers visiting friends and relatives, long-stay travellers, and those visiting areas of poor sanitation.
All travellers should take care with personal, food and water hygiene.
As hepatitis A vaccine is well tolerated and affords long-lasting protection, it is recommended for all previously unvaccinated travellers.
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 FCDO foreign travel advice website.
Typhoid is a bacterial infection transmitted through contaminated food and water. Previous typhoid illness may only partially protect against re-infection.
Vaccination is recommended for most travellers, particularly travellers visiting friends and relatives, those in contact with an infected person, young children, frequent or long-stay travellers visiting areas where sanitation and food hygiene are likely to be poor, and laboratory personnel who may handle the bacteria for their work.
All travellers should take care with personal, food and water hygiene.
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 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 countrywide, transmission is considered to be year-round.
All travellers should avoid mosquito bites particularly between dusk and dawn.
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 may be present in this country; information is limited or unavailable. 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:
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.
In low risk areas, antimalarials may be considered in exceptional circumstances for travellers who are at higher risk of malaria (such as long term travellers visiting friends and relatives), or of severe complications from malaria (such as the elderly [over 70 years], the immunosuppressed, those with complex co-morbidities, pregnant women, infants and young children). The final decision whether or not to advise antimalarials rests with the travel health advisor and the traveller after individual risk assessment.
Travellers with an absent or poorly functioning spleen should be dissuaded from travel to any area with risk of malaria. Where travel is essential awareness, rigorous bite avoidance and antimalarials should be advised, even for the low risk areas.
For special risk groups, you may wish to seek specialist advice. For the low risk areas in this country/area atovaquone/proguanil OR doxycycline OR mefloquine would be suitable options.
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. Select risk to expand information.
There is a risk of altitude illness when travelling to destinations of 2,500 metres (8,200 feet) or higher. Important risk factors are the altitude gained, rate of ascent and sleeping altitude. Rapid ascent without a period of acclimatisation puts a traveller at increased risk.
There are three syndromes; acute mountain sickness (AMS), high-altitude cerebral oedema (HACE) and high-altitude pulmonary oedema (HAPE). HACE and HAPE require immediate descent and medical treatment.
There is a point of elevation in this country higher than 2,500 metres.
Biting insects or ticks
Insect or tick bites can cause irritation and infections of the skin at the site of a bite. They can also spread certain diseases.
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.
Dengue is a viral infection transmitted by mosquitoes which predominantly feed between dawn and dusk. It causes a flu-like illness, which can occasionally develop into a more serious life-threatening form of the disease. Severe dengue is rare in travellers.
The mosquitoes that transmit dengue are most abundant in towns, cities and surrounding areas. All travellers to dengue areas are at risk.
There is a risk of dengue in this country.
Seasonal influenza is a viral infection of the respiratory tract and spreads easily from person to person via respiratory droplets when coughing and sneezing. Symptoms appear rapidly and include fever, muscle aches, headache, malaise (feeling unwell), cough, sore throat and a runny nose. In healthy individuals, symptoms improve without treatment within two to seven days. Severe illness is more common in those aged 65 years or over, those under 2 years of age, or those who have underlying medical conditions that increase their risk for complications of influenza.
Seasonal influenza occurs throughout the world. In the northern hemisphere (including the UK), most influenza occurs from as early as October through to March. In the southern hemisphere, influenza mostly occurs between April and September. In the tropics, influenza can occur throughout the year.
All travellers should:
If individuals at higher risk of severe disease following influenza infection are travelling to a country when influenza is likely to be circulating they should ensure they received a flu vaccination in the previous 12 months.
The vaccine used in the UK protects against the strains predicted to occur during the winter months of the northern hemisphere. It is not possible to obtain vaccine for the southern hemisphere in the UK, but the vaccine used during the UK influenza season should still provide important protection against strains likely to occur during the southern hemisphere influenza season, and in the tropics.
Avian influenza viruses can rarely infect and cause disease in humans. Such cases are usually associated with close exposure to infected bird or animal populations. Where appropriate, information on these will be available in the outbreaks and news sections of the relevant country pages. Seasonal influenza vaccines will not provide protection against avian influenza.
Outdoor air quality
Poor air quality is a significant public health problem in many parts of the world. Exposure to high levels of air pollution over short time periods (e.g. minutes/hours/days) and longer time periods (e.g. years) is linked to many different acute and chronic health problems. These effects are mainly on the respiratory (lungs and airways) and cardiovascular (heart function and blood circulation) systems.
Current information on world air quality is available from the world air quality index project.
Travellers with health problems that might make them more vulnerable to the effects of air pollution who are travelling to areas of high pollution should:
It is unclear if face masks are beneficial at reducing exposure and may make breathing more difficult for those with pre-existing lung conditions. Those who choose to use one should make sure that the mask fits well and know how to wear it properly.
COVID-19 disease is caused by the coronavirus SARS-CoV2. The main symptoms of COVID-19 are recent onset of a new continuous cough and/or a high temperature and/or a loss of, or change in, normal sense of taste or smell. Symptoms range from mild to life-threatening. Older people and those with underlying health problems are more likely to develop severe disease. Current evidence also shows that there is a higher risk of infection and of severe disease in Black, Asian and Minority Ethnic groups in the UK. The reasons for this are currently not clear.
The virus is mainly transmitted from human to human by breathing in droplets from the nose or mouth of an infected person or by touching the infected droplets on surfaces, then touching the eyes, nose or mouth. A COVID-19 vaccine is now available in some countries, but even if vaccinated, prevention still relies on strict attention to social distancing guidance and personal and respiratory hygiene.
Travellers should always check the UK Foreign, Commonwealth & Development Office (FCDO) travel advice and their country-specific pages for the latest COVID-19 travel advisories which may include information on travel restrictions, quarantine or COVID-19 testing requirements. This includes considering the recommendations and requirements for any transit countries. Travellers should be aware that case numbers in individual countries/areas can increase rapidly and country requirements can change at short notice. They should check this page and FCDO travel advice regularly for updates.
Based on currently available information, there is a moderate risk of exposure to COVID-19 in this country.
All travellers should check the FCDO travel advice and carefully consider the risks of exposure to COVID-19 before travel to this country. This is particularly important in those in clinically extremely vulnerable groups who may wish to seek advice before travel.
Individuals entering or returning to the UK may be required to follow additional UK border measures including self-isolation.
If travelling to this country, travellers should:
If travellers develop COVID-19 symptoms while abroad, they should:
