Cutaneous and mucocutaneous leishmaniases are widely spread in the mountainous Andean regions of South America. In Venezuela, these regions consist of the coffee-growing states of Trujillo, Merida and Tachira. Entomological and parasitological investigations in three geographically different climatic zones (Lomas Bajas, Delicias and La Grita) in Tachira state have shown a predominance of the sandfly species Lutzomyia spinicrassa (verrucarum group) and two Leishmania species, Leishmania mexicana and Leishmania braziliensis. Two transmission cycles appear to occur: a peridomestic cycle in Lomas Bajas and a sylvatic one in Delicias and La Grita.
皮肤利什曼病和黏膜皮肤利什曼病在南美洲安第斯山区广泛传播。在委内瑞拉，这些地区包括种植咖啡的特鲁希略州、梅里达州和塔奇拉州。在塔奇拉州三个地理气候不同的区域（洛马斯·巴哈斯、德利西亚斯和拉格里塔）进行的昆虫学和寄生虫学调查显示，白蛉物种斯氏罗蛉（疣蛉类）以及两种利什曼原虫物种，即墨西哥利什曼原虫和巴西利什曼原虫占主导地位。似乎存在两个传播周期：洛马斯·巴哈斯的家周缘传播周期以及德利西亚斯和拉格里塔的森林传播周期。
