Inoculation regulations can change at short notice. Please take medical advice in the case of doubt.

1
A yellow fever vaccination certificate is required from travellers aged one year and over who have visited infected or endemic areas within the previous six days.

2
Following WHO guidelines issued in 1973, a cholera vaccination certificate is no longer a condition of entry to Brunei. However, precautions are still advisable. Up-to-date information should be sought before deciding whether these precautions should include vaccination as medical opinion is divided over its effectiveness; see the Health appendix.

3
Typhoid fever occurs.

Food & drink
All water should be regarded as being potentially contaminated. Water used for drinking, brushing teeth or making ice should have first been boiled or sterilised. Milk is unpasteurised and should be boiled. Powdered or tinned milk is available and advised, but should be reconstituted with pure water. Avoid all dairy products. Only eat well-cooked meat and fish, preferably served hot. Pork, salad and mayonnaise may carry increased risk. Vegetables should be cooked and fruit peeled.

Other risks
Amoebic and bacillary dysentery and hepatitis A and E may occur. Hepatitis B is highly endemic in the region. Dengue fever and Japanese encephalitis occur occasionally.
There have been no reported cases of Avian influenza (bird flu) in Brunei, however there have been over 80 deaths reported in Asia since 2004. Visitors to Asia should be mindful of prolonged exposure to poultry or the consumption of poultry that has not been cooked to a high internal temperature.
There have been outbreaks of Hand, Foot and Mouth Disease (HFMD) across Brunei in early 2006. HFMD is a communicable disease, which affects all age groups, but children are particularly vulnerable.

Medical insurance is advised. Medical facilities are of a high standard. The health administration of Brunei reserves the right to vaccinate arrivals not in possession of required certificates and to take any other action deemed necessary to ensure arrivals present no health risk.
