Living with Endemic typhus

An infection that causes headache, fever, and a skin rash, and can occur at any age.

Understanding Endemic typhus

Endemic typhus is an infection (a rickettsial disease) that is marked by headache, fever, and a rash.

Only about one-third of people have all three of these main symptoms. It can occur at any time in life. In children, the typical symptoms appear in only about half of cases, and belly pain, diarrhea, sore throat, and anemia are more common.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Headache
  • Fever
  • Skin rash
  • Chills
  • Muscle pain (myalgia)
  • Stomach pain

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
