Typhoid fever causes a prolonged high temperature, headaches and stomach pain, and can become serious without antibiotic treatment, which is why vaccination is widely recommended ahead of travel to higher-risk regions.
Vaccination reduces but does not eliminate risk, so it is usually paired with ordinary food and water precautions such as avoiding tap water and unpeeled fruit.
Travellers visiting friends and relatives on extended trips, or those travelling to rural areas and smaller towns, are generally considered at higher risk than short resort-based stays.
