This condition affects as many as 12 million people worldwide, with 900,000 to 1.3 million new cases each year. The global incidence of leishmaniasis has increased in recent years due to increased international leisure- and military-related travel, human alteration of vector habitats, and concomitant factors that increase susceptibility, such as infection with human immunodeficiency virus (HIV) and malnutrition. With the exception of Australia, the Pacific Islands, and Antarctica, the parasites have been identified throughout large portions of the world.
