Typhoid Fever
Featured patient discussions on typhoid fever
"I contracted typhoid fever in 2005 while on vacation in Mexico.
The day of my return, I became violently ill. I had uncontrollable
diarrhea and vomiting. My fever shot up to 104 degrees, and I was
hospitalized where I remained for seven days. I was packed on ice
continually as my fever shot to 105. I suffered convulsions. The pain in
my body was so excruciating. I was put on a morphine drip, and I have a
high tolerance for pain. Blood tests showed minimal kidney function and
liver failure. Even after I was released, I continued to have fevers of
104 and 105. I was disabled by this illness for months."
How do patients get typhoid fever?
Typhoid fever is contracted by the ingestion of the bacteria in
contaminated food or water. Patients with acute illness can contaminate
the surrounding water supply through stool, which contains a high
concentration of the bacteria. Contamination of the water supply can, in
turn, taint the food supply. About 3%-5% of patients become carriers of
the bacteria after the acute illness. Some patients suffer a very mild
illness that goes unrecognized. These patients can become long-term
carriers of the bacteria. The bacteria multiplies in the gallbladder,
bile ducts, or liver and passes into the bowel. The bacteria can survive
for weeks in water or dried sewage. These chronic carriers may have no
symptoms and can be the source of new outbreaks of typhoid fever for
many years.
How does the bacteria cause disease, and how is it diagnosed?
After the ingestion of contaminated food or water, the
Salmonella
bacteria invade the small intestine and enter the bloodstream
temporarily. The bacteria are carried by white blood cells in the liver,
spleen, and bone marrow. The bacteria then multiply in the cells of these
organs and
reenter the bloodstream. Patients develop symptoms, including
fever,
when the organism reenters the bloodstream. Bacteria invade
the gallbladder, biliary system, and the lymphatic tissue of the bowel. Here,
they multiply in high numbers. The bacteria pass into the
intestinal tract
and can be identified for diagnosis in cultures from the stool
tested in
the laboratory. Stool cultures are sensitive in the early and late stages of the disease but often
must be supplemented with blood cultures to make the definite diagnosis.
What are the symptoms of typhoid fever?
The incubation period is usually one to two weeks, and the duration of
the
illness is about four to six weeks. The patient experiences
- poor
appetite;
- abdominal pain;
- headaches;
- generalized aches and pains;
- fever, often up to 104 F;
- lethargy (usually only if untreated);
- intestinal bleeding or perforation (after two to three weeks of the disease);
- diarrhea or constipation.
People with typhoid fever usually have a sustained fever as high as 103 F-104
F (39 C-40 C).
Chest
congestion develops in many patients, and abdominal pain and
discomfort are
common. The fever becomes constant. Improvement occurs in the
third and
fourth week in those without complications. About 10% of
patients have
recurrent symptoms (relapse) after feeling better for one to
two weeks.
Relapses are actually more common in individuals treated with
antibiotics.
