There is a vaccine that offers some protection against travellers’ diarrhoea, but it only covers certain causes and isn’t a substitute for careful food and water hygiene. Anyone planning a trip abroad, particularly to areas with lower sanitation standards, will want to know exactly what protection is available and what still relies on good habits.
In this blog, we’ll look at what causes travellers’ diarrhoea, whether a vaccine can help, and how to protect yourself properly before you travel.
What Causes Travellers’ Diarrhoea?
Travellers’ diarrhoea is most commonly caused by bacteria picked up through contaminated food or water. It’s one of the most frequent health complaints among people travelling to lower-income regions.
The leading cause is a bacterium known as enterotoxigenic E. coli (ETEC), although other bacteria, viruses, and parasites can also trigger the condition. Symptoms typically include loose stools, stomach cramps, and sometimes fever or nausea, usually starting within the first week of travel.
Is There a Travellers’ Diarrhoea Vaccine?
Yes, a travellers’ diarrhoea vaccine called Dukoral is available, but it only protects against ETEC and cholera, not every possible cause. This makes it a useful additional layer of protection rather than a complete solution.
Dukoral is taken orally and is typically recommended for travellers heading to high-risk regions, particularly those with underlying health conditions or a lower tolerance for illness while away. According to NHS travel health advice, vaccination should always be considered alongside, not instead of, hygiene precautions.
How to Prevent Travellers’ Diarrhoea
The most effective prevention combines sensible food and water habits with vaccination where appropriate. Neither approach alone offers complete protection.
Food and Water Precautions
Simple habits make a significant difference in reducing your risk while abroad.
- Drink bottled or purified water only.
- Skip ice cubes unless their source is confirmed safe.
- Choose meals that are freshly cooked and served hot.
- Steer clear of raw salads, unpeeled fruit, and street food from unclear sources.
- Wash hands regularly, especially before eating.
When Vaccination Is Worth Considering
Vaccination is worth considering for travellers visiting high-risk destinations, those with existing digestive conditions, or people who cannot afford to fall ill during their trip. A travel health consultation can help determine whether it’s right for you, based on your itinerary and medical history.
What to Do If You Get Travellers’ Diarrhoea
Most cases resolve within a few days with rest and rehydration. Oral rehydration salts help replace lost fluids and salts, while symptoms are usually managed rather than treated with antibiotics unless the case is severe.
For moderate to severe cases, particularly in destinations with higher antibiotic resistance, a prescriber may recommend standby treatment such as Azithromycin 250mg tablets to take with you. This is a prescription-only antibiotic and should only be used on professional advice, not as a routine preventative measure. TravelHealthPro, the UK’s official travel health resource, advises seeking medical attention if symptoms persist beyond a few days or include blood or high fever.

Frequently Asked Questions
Can vaccines fully prevent travellers’ diarrhoea?
No, the available vaccine only protects against certain causes such as ETEC and cholera. Good food and water hygiene remain essential alongside vaccination.
What is the travellers’ diarrhoea vaccine called?
The vaccine is called Dukoral and is taken orally before travel, and it’s typically recommended for higher-risk destinations or travellers with existing health conditions.
How can I prevent travellers’ diarrhoea without a vaccine?
Stick to bottled water, avoid ice and raw or unpeeled food, and wash your hands regularly, as most cases are linked to contaminated food or water.
What’s the best travellers’ diarrhoea treatment if I get ill abroad?
Rest, rehydration with oral rehydration salts, and monitoring symptoms usually resolve mild cases. Get medical help if symptoms are severe or don’t improve.
Who should consider the travellers’ diarrhoea vaccine?
Travellers to high-risk regions, those with digestive conditions, or anyone who can’t risk illness disrupting their trip should discuss vaccination with a pharmacist.
How far in advance should I book a travel health appointment?
Ideally, book at least four to six weeks before travel, as some vaccines require multiple doses or time to take full effect.
Should I carry Azithromycin 250mg tablets when travelling?
Some travellers are prescribed Azithromycin 250mg as standby treatment for moderate to severe travellers’ diarrhoea, particularly for higher-risk destinations. This is prescription-only and should be discussed with a pharmacist or GP before travel, not used routinely.
