Brunei – Health Risks, Inoculations, Vaccinations, and Health Certificates

What are the main health risks for expats living in Brunei?

Brunei’s tropical climate creates conditions highly favourable to mosquito proliferation, making vector-borne illnesses — particularly dengue fever — a persistent concern for residents and visitors alike. Dengue is a debilitating flu-like disease transmitted through the bites of infected mosquitoes that are active throughout daylight hours, from sunrise to sunset. Those affected typically experience a rapid onset of high fever accompanied by intense headaches and severe pain in the joints, bones, and muscles.

Malaria is present in Brunei Darussalam but poses a very low risk to most residents. No preventive antimalarial medication is routinely recommended for Brunei; however, cases of human P. knowlesi malaria — a strain that originates in primate populations — have been documented in the country. For this reason, bite avoidance remains an important precaution, particularly for those spending time in forested or rural settings.

As in any country, food and waterborne illnesses pose a real risk in Brunei. Traveller’s diarrhoea, hepatitis A, and typhoid fever are among the more common concerns. Residents are advised to rely on bottled or purified water rather than tap water, to steer clear of raw or inadequately cooked meat, fish, and shellfish, and to ensure that fresh produce has been thoroughly washed in clean water before consumption.

Further health hazards include leptospirosis, melioidosis, sexually transmitted infections, and tuberculosis. Japanese encephalitis is also a risk in Brunei for certain individuals, with factors such as location, accommodation type, and time of year influencing that risk. Rabies, too, is present in the country and warrants awareness.

Heat-related conditions such as heatstroke carry life-threatening potential. Staying well hydrated, choosing light and breathable clothing, and avoiding strenuous activity during the hottest parts of the day are all important safeguards. Brunei’s combination of high temperatures and oppressive humidity can be a substantial shock to those arriving from cooler, drier climates, and the process of acclimatisation should not be taken lightly.

In various parts of South-east Asia, including Brunei, insect and tick-borne diseases such as leishmaniasis and scrub typhus also represent a risk. Expats who regularly venture outdoors, visit parks, or spend time in Brunei’s expansive jungle interior should take appropriate protective measures.

Are any vaccinations or inoculations required before entering Brunei?

Yellow fever does not occur within Brunei, but the country does impose a certificate requirement in line with International Health Regulations. Travellers aged nine months and above who are arriving from countries where yellow fever transmission is a recognised risk must present a valid certificate of yellow fever vaccination. This obligation equally applies to anyone who has transited for more than 12 hours through an airport located in a yellow fever risk country.

In accordance with World Health Organization guidelines, effective from 11 July 2016, a yellow fever vaccination certificate is considered valid for the entirety of the vaccinated person’s lifetime. Authorities cannot reject a valid certificate on the basis that more than ten years have elapsed since the vaccination took effect, and neither boosters nor revaccination can be demanded as a condition of entry.

For the majority of arrivals — specifically those travelling directly from countries not classified as yellow fever risk zones — no particular inoculations or vaccinations are currently mandated as a condition of entry into Brunei. The yellow fever certificate requirement functions as a public health barrier against disease importation, not as evidence that yellow fever circulates within Brunei itself.

It is also important to be aware that Brunei maintains an HIV/AIDS-related restriction on entry. Individuals living with HIV may encounter difficulties when applying for long-term visas or employment passes, given that the mandatory medical examination required for work and residency (discussed below) incorporates HIV testing. Current policy should always be verified directly with the Brunei Department of Immigration and National Registration prior to making any application.

The WHO list of countries with yellow fever transmission risk is updated on an ongoing basis. Before travelling, consult this list to determine whether a certificate is required for your specific travel route. A specialist travel health clinic will be able to advise you based on your precise itinerary.

Which vaccinations are recommended for expats moving to Brunei?

Keeping routine vaccinations current is fundamental, particularly given the global resurgence of vaccine-preventable diseases in recent years. Before departure, individuals should ensure they are up to date with age-appropriate vaccinations, which may encompass COVID-19, hepatitis A, hepatitis B, influenza, measles/mumps/rubella (MMR), meningococcal, pneumococcal, polio, and tetanus/diphtheria/pertussis (Tdap).

The majority of those relocating to Brunei will require protection against hepatitis A and typhoid fever, along with guidance on managing traveller’s diarrhoea. Hepatitis A is transmitted through contaminated food and water, and the risk is not confined to obviously unhygienic environments — it can arise even in well-developed settings. Typhoid is similarly relevant, particularly for those who will eat at local establishments outside tourist areas or who plan to visit rural parts of the country.

Japanese encephalitis vaccination is advisable for certain individuals, depending on their intended activities and locations within Brunei. Expats planning to spend considerable time outdoors, near agricultural land, or in rural communities will face a meaningfully higher exposure risk. Rabies vaccination is typically recommended for high-risk individuals — such as veterinarians and those who work with animals — and is also worth considering for those embarking on extended outdoor pursuits, adventure activities including cycling, rural travel, or long-term residence in endemic areas, as well as for children.

Expats whose childhood immunisation programme included hepatitis B should verify this against Brunei’s own national vaccination schedule, which also incorporates hepatitis B. Those who did not receive it in their home country’s childhood programme may benefit from completing a catch-up course prior to moving.

The CDC recommends that all international travellers be fully vaccinated against measles with the MMR vaccine. Measles outbreaks have been increasing in frequency worldwide, and this recommendation applies to all adults relocating abroad who may not have received the full two-dose course.

Whether seeing a travel health clinic or a personal physician, prospective expats should aim to attend their appointment four to eight weeks before their departure date — or even earlier when multiple vaccines are needed, since some require a series of doses administered over several weeks. This lead time also ensures that vaccines reach their full protective efficacy before arrival.

Do you need a health certificate to move to or work in Brunei?

The Brunei Visa Medical is a compulsory health screening process that applies to all foreign nationals intending to take up an Employment Pass (Work Pass) or establish long-term residency in Brunei Darussalam. A medical certificate is required for all Employment Visas (Work Passes) and for any residency permit covering stays exceeding 90 days. Those on short-term social visit visas of under 90 days are generally exempt from this medical requirement, although a digital health declaration must still be completed prior to arrival.

The medical examination follows a defined sequence of steps. The typical process is outlined below:

1. Pre-departure medical in your home country: New workers must undergo a comprehensive medical examination in their home country or country of permanent residence prior to arriving in Brunei, including blood tests for communicable diseases and a chest X-ray, to prevent the spread of infectious diseases.
2. Complete the official medical form: The embassy uses a standard form — “Medical Report for Foreign Worker for Employment in Brunei Darussalam” — covering your medical history, physical examination, laboratory tests, chest X-ray, and vaccination overview.
3. Undergo laboratory tests: Testing includes conditions such as HIV, hepatitis, malaria, and tuberculosis. The medical also includes blood tests, urine tests, and a chest X-ray. For some roles, stool examination may also be required.
4. Physical examination: You should allow around one hour for the medical. The doctor will go through your medical history and undertake a thorough physical examination covering the respiratory, cardiovascular, abdominal, neurological, and musculoskeletal systems.
5. Submit results: The outcome is a medical fitness for employment certificate, which is a requirement for the issuance of the Employment Pass by the Department of Immigration and National Registration.
6. Post-arrival screening: Upon arrival in Brunei, employees will also need to undergo additional medical screening.

Given the volume of laboratory tests involved, it is advisable to schedule your medical appointment four to six weeks before your planned departure date. In most cases, Brunei medical results remain valid for three months; however, certain employers or embassy representatives may require that results be no more than two weeks old at the point of submission (as of 2025).

This medical examination is a prerequisite for the issuance of the “Green Identity Card” for those intending to stay beyond three months. Costs differ depending on country and clinic. It is essential to use an approved or accredited facility, and to confirm with the Brunei Department of Immigration and National Registration or your employer’s representative which clinics or panel physicians are recognised, as these requirements may change over time.

How does healthcare in Brunei compare to what expats may be used to?

Healthcare in Brunei is organised around a mixed public-private model. One of its defining characteristics is the extent to which public services are subsidised by the state. Rather than being financed through social insurance contributions, as is the case in many European systems, Brunei’s public healthcare infrastructure is largely supported by revenues from the country’s oil and gas sector. This arrangement makes care very affordable for citizens and permanent residents, though foreign workers face more restricted access to the public system.

Quality medical facilities are available across the country. The principal public hospital is RIPAS (Raja Isteri Pengiran Anak Saleha) Hospital in Bandar Seri Begawan, which is the largest and most comprehensively equipped healthcare institution in Brunei. Private hospitals and clinics operate in the capital as well as in Seria, the centre of the oil industry in Belait District.

In urban hospitals and larger private clinics, English is commonly spoken alongside Malay by medical professionals. Brunei’s educational tradition and historical links mean that many doctors and senior nursing staff have trained in international institutions, and English functions as a routine professional language in healthcare settings. Smaller community health centres — particularly those located away from the capital — may offer less consistent English-language access.

Expats holding Employment Passes typically access medical care through private clinics or through arrangements made by their employer. Securing comprehensive private health insurance before relocating is strongly advised, as out-of-pocket costs in the private sector can be considerable, and public facilities tend to give priority to citizens and permanent residents for non-emergency treatment. Since not all employers automatically include health coverage in employment packages, the terms of any offered plan should be reviewed with care before signing a contract.

When faced with complex or specialised medical needs, Brunei residents sometimes travel to Singapore or Malaysia for treatment. The country’s geographic position makes this relatively manageable, but it highlights the importance of holding insurance that covers medical evacuation and overseas treatment — especially for those managing long-term or complex health conditions.

What are the risks of travel within Brunei, and are there regional health differences?

Brunei is a compact nation — comparable in size to a large city — comprising four administrative districts: Brunei-Muara, which contains the capital Bandar Seri Begawan; Tutong; Belait; and Temburong. Despite its modest geographical footprint, there are notable distinctions in health risk between urban centres and more rural environments.

Temburong District, which is physically separated from the rest of Brunei by Malaysian land territory, represents the country’s most remote and heavily forested region. Those who venture into the rainforest, visit adventure tourism locations, or work in agricultural settings there face a relatively elevated risk of certain illnesses, including the uncommon but documented P. knowlesi malaria, leptospirosis — contracted through contact with water or soil contaminated by infected animals — and scrub typhus, which is transmitted through mite bites in dense vegetation.

Japanese encephalitis transmission is most closely associated with areas near pig farms and agricultural zones. Expats based or working in Tutong or Belait districts, where such environments are more common than in the capital, should discuss the Japanese encephalitis vaccine with a travel health professional.

Anyone spending time outdoors in Brunei should remain alert to shifting weather conditions and adapt activities accordingly, packing essential protective items including insect repellent and sunscreen. The monsoon season, which typically runs from around October through to January, brings heavy and sustained rainfall that can generate pools of standing water even in urban areas, providing ideal breeding conditions for the mosquitoes responsible for dengue transmission.

Urban areas around Bandar Seri Begawan do not carry notable pollution risks by the standards of the wider region, and air quality is generally considered good. That said, periods of regional haze — typically resulting from large-scale agricultural burning in neighbouring Indonesia or Malaysia — can temporarily degrade air quality significantly. Expats with respiratory conditions such as asthma should monitor local air quality indices regularly and ensure they have sufficient medication available during such episodes.

Frequently Asked Questions

Will my existing home-country vaccinations be accepted for the Brunei medical examination?

Vaccination records issued in your home country are generally recognised as part of the pre-departure medical form, which contains a section covering vaccination history. That said, the medical examination also mandates specific laboratory tests — including for HIV, hepatitis B, and tuberculosis — regardless of your prior immunisation record. Bring your complete vaccination documentation to the pre-departure appointment, and check with the Brunei embassy or your employer’s representative to confirm which records are required for your particular visa category.

Is health insurance compulsory for expats living in Brunei?

Brunei does not at present impose private health insurance as a universal legal requirement across all visa categories in the way some other countries do. However, foreign workers on Employment Passes generally have limited access to the heavily subsidised public healthcare system, and the costs associated with private medical treatment can be considerable. Comprehensive private health insurance — covering inpatient care, specialist consultations, and medical evacuation — is strongly advisable and is frequently a condition set by employers. Review the details of any employer-provided cover carefully before depending on it.

What should I do if I develop a serious illness while living in Brunei?

In an emergency, RIPAS Hospital in Bandar Seri Begawan is the country’s principal public hospital and the facility best equipped to manage serious medical cases. Private hospitals and clinics are also available in the capital and in Seria. For highly specialised treatment that is not offered locally — such as certain surgical procedures or oncology care — patients are sometimes directed to hospitals in Singapore or Malaysia. This makes medical evacuation coverage an especially valuable component of any health insurance policy. Store your insurer’s emergency contact number somewhere readily accessible at all times.

How do I find a doctor who speaks English in Brunei?

English occupies a prominent place in Brunei’s professional and educational landscape, and the majority of doctors at RIPAS Hospital and private clinics in Bandar Seri Begawan are able to consult in English without difficulty. Private clinics in Seria and other parts of Belait District also typically employ English-speaking staff. The International Association for Medical Assistance to Travellers (IAMAT) maintains a searchable directory of English-proficient doctors around the world at www.iamat.org. Your employer or the nearest embassy may also be in a position to suggest reliable local practitioners.

Is dengue fever a year-round risk in Brunei?

Yes — because Brunei’s tropical climate sustains mosquito populations throughout the year, dengue fever poses a continuous risk rather than a seasonal one. The risk may be heightened during and following the rainy season, when standing water provides additional breeding habitat for mosquitoes. Protective measures include applying a DEET-based insect repellent, wearing long-sleeved clothing and trousers especially during the hours around dawn and dusk, and sleeping under mosquito nets or in air-conditioned rooms. Anyone who develops a sudden high fever combined with severe joint pain or intense headache should seek prompt medical attention and alert the treating doctor to the possibility of dengue.

Do children moving to Brunei need any additional vaccinations or health checks?

Children travelling with working parents on dependent passes will typically be subject to similar medical screening requirements as adults for long-term residency purposes. Ensuring that children are fully current with routine vaccinations — including the full two-dose MMR course, which protects against measles amid rising global case numbers — is especially important. Rabies vaccination may also be worth considering for children; they tend to be at greater risk of serious bite injuries and may not always disclose animal contact to caregivers. A paediatric travel health specialist should be consulted well in advance of the family’s departure.

Are there any restrictions on bringing prescription medicines into Brunei?

Certain prescription drugs that are legally available in other countries may be prohibited or tightly regulated in Brunei. Brunei enforces strict controls on narcotics and other controlled substances, and some commonly prescribed medications — including certain analgesics, psychotropic drugs, and controlled compounds — may require advance authorisation or may be outright banned from importation. To avoid difficulties, carry a letter from your prescribing doctor explaining the medical necessity of your medication, keep all medicines in their original labelled packaging, and confirm the legal status of any prescription drugs with the Brunei High Commission or embassy well before you travel.

How far in advance should I arrange my pre-departure medical and vaccinations?

A travel health clinic or personal physician appointment should ideally be scheduled four to eight weeks before your departure date. For the work visa pre-departure medical specifically, booking four to six weeks ahead is recommended to allow sufficient time for all laboratory results to be returned and for completed forms to be properly submitted. Certain vaccines — such as the three-dose hepatitis B series or the Japanese encephalitis course — require multiple appointments spread over several weeks, making early planning all the more important.
