Typhoid fever is caused by Salmonella typhi bacteria. Typhoid fever is rare in industrialized countries. However, it remains a serious health threat in the developing world, especially for children.
Typhoid fever spreads through contaminated food and water or through close contact with someone who’s infected. Signs and symptoms usually include a high fever, headache, abdominal pain, and either constipation or diarrhea.
Most people with typhoid fever feel better within a few days of starting antibiotic treatment, although a small number of them may die of complications.
