Risk to travellers of cholera

The risk to travellers in general has been estimated as 0.2 cases per 100 000 European and North American travellers

• this figure may be deceptive - this is because many travellers experience few or very mild symptoms and consequently they may not seek medical help
• the risk is increased if the traveller is living in unhygienic conditions, travelling to remote areas or working in a disaster area or refugee camp (1).

The best way of prevention when travelling is to follow food and water hygiene:

• wash hands after using the toilet and before cooking or eating
• disinfect drinking water by boiling, using water purification tablets or water filtration devices:
  • avoid ice. Bottled, carbonated drinks, with intact seals and hot drinks made with boiled water are usual safe.
  • use bottled water or boiled, cooled tap water for brushing your teeth. Don’t use water from natural sources such as rivers or streams, uncovered wells or untreated tap water.
• try to eat recently prepared, thoroughly cooked food, served piping hot:
  • salads or uncooked fruit and vegetables should not be consumed unless they have been washed and peeled carefully
  • buffets, food from street traders, unpasteurised dairy products and raw or undercooked meat, fish or shellfish should be avoided (1).
