Living with Leishmaniasis

A parasite disease spread by sand fly bites that can cause skin sores or affect organs like the liver and spleen.

Understanding Leishmaniasis

Leishmaniasis is a parasitic disease spread by the bite of infected sand flies.

There are several forms. The most common are cutaneous, which causes skin sores, and visceral, which affects internal organs such as the spleen, liver, and bone marrow. It is found in parts of the Middle East, Central and South America, Asia, Africa, and southern Europe. It is possible but very unlikely to get it in the United States.

Signs & symptoms

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

  • Fever that comes and goes
  • Weight loss
  • Enlarged spleen and liver
  • Open skin sores (ulcers)
  • Swollen lymph nodes
  • Anemia (low red blood cells)

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.
