Traveller notes
Use sealed bottled water or filtered refill stations in hotels, cafes, and hostels.
Ice in established restaurants is commonly commercially produced, but avoid unknown street-stall ice.
Be careful with raw herbs, salad, and cut fruit if you are unsure how they were washed.
Practical advice
In Vietnam, buy sealed bottled water from supermarkets, hotels, or established shops. Check the seal is intact before drinking — refilled bottles are sold in some markets.
A filter bottle (LifeStraw, Grayl, Sawyer) covers any tap source and saves money and plastic on longer trips. UV pens (SteriPEN) also work for clear water.
A full rolling boil for at least one minute kills bacteria, viruses, and protozoa. This is the cheapest and most reliable treatment if your accommodation has a kettle.
Avoid ice unless you can confirm it was made from filtered or bottled water. Salads and unpeeled fruit washed in tap water can also carry pathogens — peel fruit yourself or order cooked vegetables.
Traveller's diarrhoea is usually short and self-limiting. Oral rehydration salts (ORS) are widely available — keep sipping fluids. See a doctor if symptoms persist beyond 48 hours, you have a fever, or you see blood.
