Living with Fusariosis

A fungal infection that can affect the eyes, nails, skin, and sinuses, and can spread in people with weak immune systems.

Understanding Fusariosis

Fusariosis is an infection caused by Fusarium, a fungus often found in soil and water.

Fusarium fungus mainly gets into the body through an injury. It can cause infections of the eye surface (keratitis) and nails (onychomycosis), and less often of the abdomen lining or skin. People with weak immune systems are more likely to have the infection spread through the body. It can happen at any time in life.

Signs & symptoms

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

  • Fever
  • Nail infection (onychomycosis)
  • Skin changes, including lesions and nodules under the skin
  • Sinus inflammation (sinusitis)
  • Pneumonia
  • Low white blood cell count (low neutrophils)

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.

  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Which kind of fusariosis do I have: on the surface or spread through the body?
Does my immune system affect how this infection may behave?
Which specialists should be on my care team?
