The term "Aleppo boil" refers to a skin infection caused by the bites of sandflies. Its spelling, "Aleppo", comes from the Syrian city where the disease was first identified. The word "boil" describes the appearance of the lesions on the skin. In IPA phonetic transcription, "Aleppo" is pronounced as /əˈlep.oʊ/, with emphasis on the first syllable. "Boil" is pronounced as /bɔɪl/. Although the causes, symptoms, and treatments of Aleppo boil have been studied, the disease remains a significant public health concern in certain regions of the world.
Aleppo boil, also known as cutaneous leishmaniasis, is a disease caused by a parasitic infection with the Leishmania protozoan. It is characterized by the formation of ulcerative skin lesions, primarily on exposed body parts. The name "Aleppo boil" originates from the Syrian city of Aleppo, where the disease was first extensively studied.
The infection occurs when an individual is bitten by infected sand flies, specifically of the Phlebotomus or Lutzomyia species. These sand flies transmit the parasite into the human bloodstream, where it invades and multiplies within certain immune cells called macrophages. The ensuing immune response leads to the development of painful, slow-healing skin sores or ulcers.
The lesions usually appear several weeks or months after the initial infection and can vary in size, ranging from small papules to larger nodules or open sores. The ulcerative lesions may be accompanied by symptoms such as localized pain, itching, and inflammation. If left untreated, the ulcers may persist for months or even years, but they eventually heal without scarring in most cases.
Aleppo boil is endemic in various regions across Africa, Asia, and the Americas. It primarily affects populations living in rural or impoverished communities with limited access to healthcare and inadequate housing conditions. Prevention and control measures include the use of insect repellents, protective clothing, and bed nets, as well as the elimination of sand fly breeding sites. Treatment typically involves the administration of antiparasitic drugs, which can vary depending on the specific species of Leishmania and the severity of the infection.
