Introduction. Leishmaniasis is an endemic zoonotic disease widely distributed in Peru. Objectives. Identify transmission scenarios and the population residing in them and identify the characteristics of the affected populations during the period 2010–2022. Methods. Descriptive, cross-sectional, ecological study with district as analysis units. Publicly accessible secondary data sources were used. Results. During the study period, 85,117 cases were reported; 7,374,007 (22.08%) inhabitants live in 543 districts with continuous transmission; 1,146,7420 (34.33%) inhabitants reside in 454 districts with sporadic reports of cases; and 1,455,8983 (43.59%) reside in 893 transmission-free districts. 98.16% of the cases occurred in districts with continuous transmission; 1.84% occurred in districts with sporadic case reports. The mean annual incidence rate was 3.48 cases/10,000 inhabitants. 18 departments report continuous transmission; Madre de Dios (42.45 cases/10,000 inhabitants) and Cusco (15.78 cases/10,000 inhabitants) report the highest rates. The populations with higher absolute risk are men, adolescents, and young people; residents: from jungle districts; from the quintile with the highest monetary poverty; from the quintile with the highest percentage with at least 1 NBI; and from the quintile with the lowest human development index. Conclusion: Leishmaniasis is widely distributed in Peru, with 56.41% of the population living in districts reporting cases. There are population groups with a higher absolute risk, which can be the target of differentiated prevention and control interventions.
