Brazil is the first of the 12 priority countries in Latin America with the highest number of cases of American cutaneous leishmaniasis (ACL). This study estimated the prevalence of ACL in Brazil and classified the states according to the different levels of endemicity in the period from 2014 to 2024. This is a retrospective and cross-sectional study of ACL cases registered in Brazil by the Information System for Notifiable Diseases of the Ministry of Health. The predominant cases were male (73.2%), brown (65.0%), aged between 20 and 39 (41.5%), with a low level of education (44.4%), 0.5% in pregnant women, 80% of cases were confirmed by laboratory criteria, and 90% were classified as cutaneous. A total of 182,072 autochthonous cases were recorded, with a prevalence of 89.6 cases per 100,000 population. Two states were classified as having high intense endemicity; three were classified as having medium intense endemicity; four were classified as having low intense endemicity; five states were classified as having moderate endemicity; and 13 were classified as having low endemicity. The municipality of Presidente Figueiredo, Amazonas, had the highest prevalence of ACL (5503.1%), while Belo Horizonte had the lowest prevalence (72.2%). The month with the highest average number of cases was January with 1731 (with a standard deviation of 364; upper limit of 1933; lower limit of 1572). The heterogeneity of endemicity among States suggests that social and environmental determinants influence the dynamics of ACL transmission. All sociodemographic, clinical, and epidemiological categories, when compared with the different levels of endemicity, showed significant effects (p < 0.05), except for the variable gestational status in high disease endemicity. The inclusion of these variables significantly improved the model’s ability to predict the dependent variable.
