Short Description:Leishmaniasis
Long Description:Leishmaniasis

Consider the following ICD-10 codes with a higher level of specificity:

  • B55.0 - Visceral leishmaniasis
  • B55.1 - Cutaneous leishmaniasis
  • B55.2 - Mucocutaneous leishmaniasis
  • B55.9 - ... unspecified

Clinical Information

  • LEISHMANIASIS-. a disease caused by any of a number of species of protozoa in the genus leishmania. there are four major clinical types of this infection: cutaneous old and new world leishmaniasis cutaneous diffuse cutaneous leishmaniasis diffuse cutaneous mucocutaneous leishmaniasis mucocutaneous and visceral leishmaniasis visceral.
  • LEISHMANIASIS MUCOCUTANEOUS-. a disease characterized by the chronic progressive spread of lesions from new world cutaneous leishmaniasis caused by species of the l. braziliensis complex to the nasal pharyngeal and buccal mucosa some time after the appearance of the initial cutaneous lesion. nasal obstruction and epistaxis are frequent presenting symptoms.
  • LEISHMANIASIS VISCERAL-. a chronic disease caused by leishmania donovani and transmitted by the bite of several sandflies of the genera phlebotomus and lutzomyia. it is commonly characterized by fever chills vomiting anemia hepatosplenomegaly leukopenia hypergammaglobulinemia emaciation and an earth gray color of the skin. the disease is classified into three main types according to geographic distribution: indian mediterranean or infantile and african.
  • LEISHMANIASIS CUTANEOUS-. an endemic disease that is characterized by the development of single or multiple localized lesions on exposed areas of skin that typically ulcerate. the disease has been divided into old and new world forms. old world leishmaniasis is separated into three distinct types according to epidemiology and clinical manifestations and is caused by species of the l. tropica and l. aethiopica complexes as well as by species of the l. major genus. new world leishmaniasis also called american leishmaniasis occurs in south and central america and is caused by species of the l. mexicana or l. braziliensis complexes.
  • LEISHMANIASIS DIFFUSE CUTANEOUS-. a form of leishmaniasis cutaneous caused by leishmania aethiopica in ethiopia and kenya l. pifanoi in venezuela l. braziliensis in south america and l. mexicana in central america. this disease is characterized by massive dissemination of skin lesions without visceral involvement.
  • LEISHMANIASIS VACCINES-. vaccines or candidate vaccines used to prevent infection with leishmania.

Information for Patients


Leishmaniasis is a parasitic disease spread by the bite of infected sand flies. There are several different forms of leishmaniasis. The most common are cutaneous and visceral. The cutaneous type causes skin sores. The visceral type affects internal organs such as the spleen, liver, and bone marrow. People with this form usually have fever, weight loss, and an enlarged spleen and liver.

Leishmaniasis is found in parts of about 88 countries. Most of these countries are in the tropics and subtropics. It is possible but very unlikely that you would get this disease in the United States. But you should be aware of it if you are traveling to the Middle East or parts of Central America, South America, Asia, Africa or southern Europe.

Treatment is with medicines that contain antimony, a type of metal, or with strong antibiotics. The best way to prevent the disease is to protect yourself from sand fly bites:

  • Stay indoors from dusk to dawn, when sand flies are the most active
  • Wear long pants and long-sleeved shirts when outside
  • Use insect repellent and bed nets as needed
