Typhoid, also known as typhoid fever or enteric fever, is an infection caused by the bacteria Salmonella typhi.
Across the world, millions of people are infected annually by typhoid, and about 200,000 of them die. The number of people infected with typhoid each year is very low in North America and the industrialized world, but typhoid is common in developing countries.
Typhoid is usually curable, but some bacterial strains are becoming increasingly resistant to antibiotics. Most people with typhoid in North America acquire it while travelling to developing areas of the world.
If untreated, about 10% to 16% of people with typhoid will die. This drops to less than 1% when people are treated promptly.
