Living with Coccidioidomycosis

A fungal infection, often with mild flu-like symptoms, that can lead to pneumonia and wider infection.

Understanding Coccidioidomycosis

Coccidioidomycosis is a fungal infection caused by Coccidioides immitis.

People usually have mild flu-like symptoms. Pneumonia and infection that spreads through the body with abscesses may develop as complications. GARD lists onset at any time in life.

Signs & symptoms

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

  • Mild flu-like symptoms
  • Fever
  • Pneumonia
  • Lowered immune function

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.
