Practical advice

How to stay hydrated safely

Buy bottled from reputable shops

In Guinea-Bissau, buy sealed bottled water from supermarkets, hotels, or established shops. Check the seal is intact before drinking — refilled bottles are sold in some markets.

Use a travel water filter

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.

Boil water if you have a kettle

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.

Be careful with ice and food washing

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.

If you do get sick, hydrate aggressively

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.

Can I drink tap water in Guinea-Bissau?

Tap water in Guinea-Bissau is unsafe — use sealed bottled water.
