Clinical Classification

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 Vaccines

    vaccines or candidate vaccines used to prevent infection with leishmania.
  • 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, 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.
  • Leishmania

    a genus of flagellate protozoa comprising several species that are pathogenic for humans. organisms of this genus have an amastigote and a promastigote stage in their life cycles. as a result of enzymatic studies this single genus has been divided into two subgenera: leishmania leishmania and leishmania viannia. species within the leishmania leishmania subgenus include: l. aethiopica, l. arabica, l. donovani, l. enrietti, l. gerbilli, l. hertigi, l. infantum, l. major, l. mexicana, and l. tropica. the following species are those that compose the leishmania viannia subgenus: l. braziliensis, l. guyanensis, l. lainsoni, l. naiffi, and l. shawi.
  • Leishmania donovani

    a parasitic hemoflagellate of the subgenus leishmania leishmania that infects man and animals and causes visceral leishmaniasis (leishmaniasis, visceral). the sandfly genera phlebotomus and lutzomyia are the vectors.
  • American Cutaneous Leishmaniasis

    the most common form of leishmaniasis that is transmitted through the bite of female phlebotomine sand flies or after exposure to leishmania parasites. it is characterized by skin lesions at the site of insect bite which typically develop within weeks or months after exposure. the lesions typically progress from small papules to open sores with raised borders and central ulcers which can be covered with scales or crust.
  • Asian Desert Cutaneous Leishmaniasis

    an acute necrotizing form of cutaneous leishmaniasis caused by infection with leishmania tropica major.
  • Cutaneous Leishmaniasis

    leishmaniasis affecting the skin. it is the most common form of leishmaniasis. it presents with erythematous macules and papules, and nodules which may eventually ulcerate. the lesions appear in the bite site in the exposed skin areas.
  • Kala-Azar|Visceral Leishmaniasis

    a chronic parasitic infection affecting the viscera and caused by leishmania donovani. signs and symptoms include fever, anorexia, fatigue, lymphadenopathy, anemia, and hepatosplenomegaly. if left untreated it may lead to death.
  • Leishmaniasis

    a parasitic infection caused by protozoa of the genus leishmania. it is transmitted to humans via the bite of sandflies. there are three main forms of the disease: cutaneous, mucocutaneous, and visceral leishmaniasis. cutaneous leishmaniasis causes skin ulcers; mucocutaneous leishmaniasis causes destructive lesions of the mucous membranes of the nose, mouth, and throat; visceral leishmaniasis is the most severe form of the disease and is manifested with anemia, weight loss, hepatomegaly and splenomegaly.
  • Post Kala-Azar Dermal Leishmaniasis

    a cutaneous form of leishmaniasis which sometimes occurs after visceral leishmaniasis treatment. it is characterized by hypo-pigmented macules, papules, plaques, nodules, or facial erythema; and is considered to be a durable infection reservoir for visceral leishmaniasis.

Patient Education


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

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
