Travel

If you’re travelling to a country where there’s a high risk of getting the condition, the Information below can help prevent infection:

• Don’t drink the local water unless you’re sure it’s clean (sterile) – drink bottled water or drinks in sealed cans or bottles.
• If the water isn’t sterile, boil it for several minutes or use chemical disinfectant or a reliable filter.
• Don’t clean your teeth with tap water.
• Don’t have ice in your drinks because it may be made from unclean water.
• Avoid fresh fruit or vegetables that can’t be peeled before eating.
• Avoid food and drink sold by street vendors, except drinks in properly sealed cans or bottles.

NHS choices

Future advise especially when travelling to an infectious country:

• Fresh foods: those that are peeled or cooked are the safest
• Avoid high risk foods like shellfish
• Boiling water is the best method of sterilisation
• Chemicals are useful for preparing safe drinking water but have their limitations
• Chlorine-based tablets are widely available and will be appropriate for most travellers
• More intrepid travellers and those planning to use surface waters as a drinking water source should use an iodine-based product.

• Iodine or chlorine used for water purification (as discussed later) can also be used for soaking and manufacturers of food products give recommendations for the appropriate concentrations.

There are three methods by which the traveller can prepare clean drinking water:

• Boiling:
  • Boil water for a full five minutes at any altitude.
• Chemical disinfection:
  • Iodine, chlorine, katedyne silver.
• Filtration
