Introduction: Leishmaniasis is a zoonosis transmitted between mammals through the bite of the female sand fly, of the genus Lutzomyia. This parasitic disease presents in three clinical forms: cutaneous, mucocutaneous and visceral. It is endemic to hot and vulnerable rural areas. In Colombia, members of armed groups frequently pass through these areas and the prevalence of this pathology in said population is unknown. This study aims to determine the seroprevalence of VL in FARC demobilized in the Miravalle rural area of the department of Caquetá. Method: cross-sectional study in the population of 60 demobilized FARC in the Miravalle green zone of Caquetá. The seroprevalence of visceral leishmaniasis was determined by enzyme-linked immunosorbent assay (ELISA). Result: 40 people agreed to participate in the study, 52% were female, 30% had Leishmania lesions, and received treatment with glucantime. The prevalence of visceral Leishmania (VL) was 1.6% and 8.3% of people with cutaneous leishmaniasis and there was no association between the different blood groups and the disease. Discussion: Which leads us to think that despite the low incidence or prevalence of VL, it has always been latent in the national territory and, as it is a disease of great impact, it is necessary to carry out more studies on seroprevalence in different population groups.
