Typhoid fever

  1. 1. Typhoid feverEnteric feverLast reviewed: June 9, 2011.Typhoid fever is an infection that causes diarrhea and a rash -- most commonly due to a type of bacteriacalled Salmonella typhi (S. typhi).Causes, incidence, and risk factorsThe bacteria that cause typhoid fever -- S. typhi -- spread through contaminated food, drink, or water. Ifyou eat or drink something that is contaminated, the bacteria enter your body. They travel into yourintestines, and then into your bloodstream, where they can get to your lymph nodes, gallbladder, liver,spleen, and other parts of your body.A few people can become carriers of S. typhi and continue to release the bacteria in their stools foryears, spreading the disease.Typhoid fever is common in developing countries, but fewer than 400 cases are reported in the U.S.each year. Most cases in the U.S. are brought in from other countries where typhoid fever is common.Symptoms
  2. 2. Early symptoms include fever, general ill-feeling, and abdominal pain. A high (typically over 103 degreesFahrenheit) fever and severe diarrhea occur as the disease gets worse.Some people with typhoid fever develop a rash called "rose spots," which are small red spots on theabdomen and chest.Other symptoms that occur include:•Abdominal tenderness•Agitation•Bloody stools•Chills•Confusion•Difficulty paying attention (attention deficit)•
  3. 3. Delirium•Fluctuating mood•Hallucinations•Nosebleeds•Severe fatigue•Slow, sluggish, lethargic feeling•WeaknessSigns and testsA complete blood count (CBC) will show a high number of white blood cells.
  4. 4. A blood culture during the first week of the fever can show S. typhi bacteria.Other tests that can help diagnose this condition include:•ELISA urine test to look for the bacteria that cause Typhoid fever•Fluorescent antibody study to look for substances that are specific to Typhoid bacteria•Platelet count (platelet count will be low)•Stool cultureTreatmentFluids and electrolytes may be given through a vein (intravenously), or you may be asked to drinkuncontaminated water with electrolyte packets.Appropriate antibiotics are given to kill the bacteria. There are increasing rates of antibiotic resistancethroughout the world, so your health care provider will check current recommendations beforechoosing an antibiotic.
  5. 5. Expectations (prognosis)Symptoms usually improve in 2 to 4 weeks with treatment. The outcome is likely to be good with earlytreatment, but becomes poor if complications develop.Symptoms may return if the treatment has not completely cured the infection.Complications•Intestinal hemorrhage (severe GI bleeding)•Intestinal perforation•Kidney failure•PeritonitisCalling your health care provider
  6. 6. Call your health care provider if:•You have had any known exposure to typhoid fever•You have been in an endemic area and you develop symptoms of typhoid fever•You have had typhoid fever and the symptoms return•You develop severe abdominal pain, decreased urine output, or other new symptomsPreventionVaccines are recommended for travel outside of the U.S., Canada, northern Europe, Australia, and NewZealand, and during epidemic outbreaks. If you are traveling to an area where there is typhoid fever, askyour health care provider if you should bring electrolyte packets in case you get sick.Immunization is not always completely effective and at-risk travelers should drink only boiled or bottledwater and eat well-cooked food. Studies of an oral live attenuated typhoid vaccine are now under wayand appear promising.Water treatment, waste disposal, and protecting the food supply from contamination are importantpublic health measures. Carriers of typhoid must not be allowed to work as food handlers.
