Situation and vulnerability
The risk increases when drinking water and sanitation are insufficient. Children are particularly affected; travellers must take into account their destination.
Signs and limits of their interpretation
Prolonged fever, fatigue, headache, abdominal pain and constipation or diarrhoea may occur. Serious complications are possible.
Diagnosis and monitoring
Blood tests can confirm infection. Specify the journey and antibiotics already taken, which are important for the evaluation and choice of treatment.

Prevention and care
Associate food precautions, safe water and vaccine advice if relevant. Antibiotics should be adapted to resistance; follow the recommended prescription and controls.
Practical issues
Does the disappearance of the fever rule out any portage?
No: people can still eliminate the bacteria after improvement. Wash your hands and avoid preparing other people's meals during the specified period; ask for the necessary checks.
