Signs and symptoms are likely to develop gradually — often appearing one to three weeks after exposure to the disease.

Early illness

Once signs and symptoms do appear, you're likely to experience:

  • Fever that starts low and increases daily, possibly reaching as high as 104.9 F (40.5 C)
  • Headache
  • Weakness and fatigue
  • Muscle aches
  • Sweating
  • Dry cough
  • Loss of appetite and weight loss
  • Abdominal pain
  • Diarrhea or constipation
  • Rash
  • Extremely swollen abdomen

Later illness

If you don't receive treatment, you may:

  • Become delirious
  • Lie motionless and exhausted with your eyes half-closed in what's known as the typhoid state

In addition, life-threatening complications often develop at this time.

In some people, signs and symptoms may return up to two weeks after the fever has subsided.

When to see a doctor

See a doctor immediately if you suspect you have typhoid fever. If you become ill while traveling in a foreign country, call the U.S. Consulate for a list of doctors. Better yet, find out in advance about medical care in the areas you'll visit, and carry a list of the names, addresses and phone numbers of recommended doctors.

If you develop signs and symptoms after you return home, consider consulting a doctor who focuses on international travel medicine or infectious diseases. A specialist may be able to recognize and treat your illness more quickly than can a doctor who isn't familiar with these areas.
