Cutaneous leishmaniasis, transmitted by female sandflies, produces skin lesions of varying size and shape. In Colombia, the insect vector of the disease is native to the same forested environments that have served as the main stage for one of the longest and most violent wars in Latin American history. As a result, the populations most affected by leishmaniasis in Colombia are members of the state army and nonstate armed groups.

Lina Pinto-García explores how leishmaniasis and the armed conflict are inextricably connected and mutually reinforcing. Maraña means "tangle" in Spanish but is also commonly used in Colombia to name the entangled greenery, braided lianas, and dense foliage that characterize the tropical forests where leishmaniasis transmission typically occurs. Pinto-García argues that leishmaniasis and the war are not merely linked but enmarañadas to each other through narratives, technologies, and practices produced by the state, medicine, biomedical research, and the armed conflict itself. All told, Maraña is a passionate study of how war has shaped the production of scientific knowledge about leishmaniasis and access to its treatments in Colombia.
