Most people worry about sunburn or lost luggage before a trip. Far fewer think about the bacteria that can be hiding in a glass of tap water or a bowl of washed salad.
Typhoid fever is rare in the UK, but it remains a real risk for travellers. In fact, the UK Health Security Agency reported 702 cases of typhoid and paratyphoid in 2024 across England, Wales and Northern Ireland, the highest number recorded to date. The majority were linked to travel to countries where sanitation and clean water access can vary significantly.
That is why typhoid fever prevention should be part of your travel plans, not an afterthought. Understanding how typhoid spreads and the best ways to prevent typhoid infection, from careful food and water safety to appropriate vaccination, can help you reduce your risk and travel more confidently.
How does typhoid spread from person to person?
Typhoid spreads through the faecal-oral route, usually when someone consumes food or water contaminated with Salmonella Typhi bacteria. This often happens in areas where sewage systems and clean water supplies are not reliable.
If a person with typhoid does not wash their hands properly after using the toilet, bacteria can pass into food or drinks they prepare. In some cases, untreated water used for drinking, washing fruit, or making ice can also carry the infection.
Can you catch typhoid through close contact?
Yes, but it is less common. Typhoid can spread through close contact if hygiene is poor, particularly in households where someone is infected. Sharing food prepared by someone who has not washed their hands properly increases risk.
It is not usually spread through casual contact such as hugging or sitting next to someone.
Which countries have a higher typhoid risk?
Typhoid risk is higher in parts of:
- South Asia, including India, Pakistan and Bangladesh.
- Sub-Saharan Africa.
- Parts of Southeast Asia.
- Some areas of Central and South America.
If you are visiting friends and relatives in these regions, your risk may be higher than standard holiday travel because you are more likely to eat local food and stay in local homes.
What are the best ways to prevent typhoid infection?
The best ways to prevent typhoid infection involve a combination of vaccination and careful hygiene practices. No single measure offers complete protection, so a layered approach is recommended.
Why are food and water safety important to prevent typhoid?
Food and water safety to prevent typhoid is essential because most infections occur through contaminated meals or drinks.
When travelling to higher-risk areas:
- Drink only bottled or properly treated water.
- Avoid ice unless you know it is made from safe water.
- Eat food that is freshly cooked and served hot.
- Avoid raw salads and unpeeled fruits.
- Wash hands regularly with soap and safe water.
These steps significantly reduce your exposure to Salmonella Typhi.
Does hand hygiene really make a difference?
Yes. Regular handwashing with soap and clean water is one of the simplest and most effective forms of typhoid fever prevention.
Wash your hands:
- After using the toilet.
- Before preparing food.
- Before eating.
If soap and water are not available, use an alcohol-based hand sanitiser, but remember that sanitiser does not replace proper washing when hands are visibly dirty.
How effective is the typhoid vaccine?
Typhoid vaccine effectiveness is good but not absolute. Vaccination significantly reduces your risk of infection, but it does not provide 100 per cent protection.
In the UK, two main types of typhoid vaccination for travellers are available. One is given as a single injection, and the other is taken as capsules over several days. Our pharmacists will advise which option is suitable based on your age, health, and travel plans.
How long does protection last?
The injectable typhoid vaccine usually provides protection for around three years. The oral capsule vaccine also offers protection for about three years.
If you continue to travel to high-risk areas, a booster dose is generally recommended every three years to maintain protection.
Even after vaccination, you should still follow strict food and water safety advice, as typhoid vaccine effectiveness is high but not complete.
Who should consider typhoid vaccination for travellers?
Typhoid vaccination for travellers is recommended for people visiting areas where typhoid is common, particularly if:
- You are staying for a long period.
- You are visiting friends or relatives.
- You are travelling to rural areas.
- You may have limited access to clean food and water.
Our pharmacists can review your itinerary and medical history to advise on appropriate vaccines.
How early should you seek travel health advice before a trip?
You should seek travel health advice at least six to eight weeks before departure. This allows enough time for vaccination and any booster doses if required.
During your appointment, our pharmacists will assess your destination, length of stay, accommodation type, and planned activities. This helps ensure you receive tailored advice on typhoid fever prevention and other relevant travel vaccines.
If you develop symptoms such as prolonged fever, stomach pain, or severe diarrhoea during or after travel, seek urgent medical assessment and mention your recent travel history.
Planning travel to a high-risk area? Here is what to do
Typhoid is preventable with the right precautions. Combining vaccination with careful hygiene and safe eating habits gives you the strongest protection. Planning ahead allows you to travel with greater confidence, knowing you have taken practical steps to reduce your risk.

FAQs
Can I get typhoid from ice in drinks abroad?
Yes. If ice is made from contaminated tap water, it can carry Salmonella Typhi. Avoid ice unless you are certain it was made using safe, treated or bottled water.
Is bottled water always safe to prevent typhoid?
Bottled water is usually safer in high-risk countries, but always check the seal is intact. Use it for drinking and brushing teeth, and avoid untreated tap water.
What are the first symptoms of typhoid fever?
Early symptoms of typhoid include persistent high temperature, headache, stomach pain, constipation or diarrhoea, and tiredness. Seek urgent medical assessment if you feel unwell after travel.
How long before travel should I get the typhoid vaccine?
You should have the typhoid vaccine at least two weeks before travel. Ideally, book a travel health appointment six to eight weeks before departure for full advice.
Can I still get typhoid after being vaccinated?
Yes. Typhoid vaccine effectiveness is high but not complete. Vaccination reduces your risk and severity, but you must still follow strict food and water safety precautions.
What foods should I avoid to reduce the risk of typhoid?
Avoid raw salads, unpeeled fruits, undercooked meat, shellfish, and street food where hygiene is uncertain. Choose freshly cooked food served hot to lower infection risk.
