In Maraña: War and Disease in the Jungles of Colombia (University of Chicago Press, 2025), Lina Pinto-García delves into the relationship between war and disease, focusing on Colombian armed conflict and the skin disease known as cutaneous leishmaniasis. Leishmaniasis is transmitted through the bite of female sandflies. The most common manifestation, cutaneous leishmaniasis, is neither deadly nor contagious: it affects the skin by producing 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 civil wars in Latin American history. As a result, the populations most affected by leishmaniasis in Colombia are members of the state army and non-state armed groups. 

Pinto-García explores how leishmaniasis and the armed conflict are inextricably connected and mutually reinforcing. Her title, 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 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. She also uses the concept of desenmarañados (disentangled) to discuss how other attachments between leishmaniasis and society could be formed through different scientific programs, technological designs, healthcare practices, regulations, and social and cultural processes capable of challenging violence, suffering, and inequality. 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.

This episode is hosted by Elena Sobrino, a lecturer in the Science and Technology Studies Program at Tufts University. Her research explores volunteer work, union histories, and environmentalism in the Flint water crisis. She is currently writing about the politics of fatigue and crisis, and teaching courses on science and technology studies, ethnographies of crisis, and global racisms.
