What is typhoid fever?
Typhoid fever, also called enteric fever, is a contagious, potentially life-threatening bacterial infection. Typhoid fever is caused by the bacterium Salmonella enteric serotype Typhi (also known as Salmonella Typhi), which is carried by infected humans in the blood and digestive tract and spreads to others through food and drinking water contaminated with infected feces. Symptoms of typhoid fever include fever, rash, and abdominal pain.
Infectious Disease Spotlight
Typhoid fever is a major international health threat regardless of age, race or background. An estimated 22 million cases of typhoid fever and 216,000 related deaths occur worldwide each year, according to the World Health Organization (Source: WHO).
However, there are relatively few cases of typhoid fever reported in the United States. Most U.S. cases occur in people who have traveled to developing countries or continents where it is particularly prevalent, such as India, Southeast Asia, Africa, and South America.
Fortunately, typhoid fever is treatable, especially in its early stages, and a vaccine is available to help prevent the disease if you plan on living in or traveling to high-risk areas of the world.
To help prevent typhoid fever with vaccination, you should seek prompt medical care before traveling to developing countries and high-risk areas. You should also seek prompt medical care if you know you have been exposed to the disease, or if you have symptoms, such as diarrhea, abdominal pain, rash, and fever, especially after visiting high-risk areas. Early diagnosis and treatment reduce the risk for serious complications, such as peritonitis and kidney failure.
Seek immediate medical care (call 911) if you, or someone you know, have serious symptoms, such as severe abdominal pain, decreased or no urination, major rectal bleeding or bloody stool, or a change in alertness.

Typhoid fever is a treatable disease and can often be cured with a full course of antibiotics, such as ampicillin, trimethoprim-sulfamethoxazole, or ciprofloxacin.
