Health Risks for Travelers

Travelers may be at risk of water-related illnesses, even though locals seem unaffected. This is often due to differences in gut flora, immune response, and exposure to local pathogens.

  • Health risks from unsafe drinking water may include:
  • Acute diarrheal disease caused by E. coli
  • Parasitic infections like giardiasis or cryptosporidiosis
  • Viral illnesses such as hepatitis A, especially in areas with poor wastewater management
  • Toxic exposure to heavy metals or residual industrial waste

Contamination is more likely in:

  • Villages or isolated areas with untreated surface water
  • Places where flooding or poor infrastructure compromises sanitation
  • Dwellings with outdated plumbing systems or neglected storage tanks

Clear water isn’t always clean water—invisible pathogens, bacteria, and pollutants can pose serious travel health hazards if consumed unfiltered.

If you experience persistent symptoms while traveling in Brunei, consult a local doctor or pharmacist. In many tourist areas, English-speaking care is available.
