Clinical Information

  • 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.

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
