Geoepidemiological Profile of Venomous Animal Incidents in Indigenous and Non-Indigenous Populations in Brazil

This study analyzes venomous animal incidents between 2012 and 2023 using data from the Notifiable Diseases Information System (SINAN), focusing on differences between indigenous and non-indigenous populations. The adopted methodology is cross-sectional and ecological, incorporating descriptive statistical analyses and Moran's spatial autocorrelation to examine geographic patterns and identify prevalence clusters. The results reveal a concentration of notifications in the Southeast region. Among the groups analyzed, the indigenous population exhibited the highest prevalence rate, with 2,654 cases per 100,000 inhabitants, demonstrating significant vulnerability to venomous animal incidents. Indigenous children and adolescents were particularly susceptible in terms of age groups. Regarding causative agents, scorpions led among non-indigenous individuals (57.3%), while snakes were more prevalent among indigenous groups (56.6%). The study underscores the need for public policies and prevention strategies that consider the cultural and environmental specificities of vulnerable populations, emphasizing the importance of educational and public health actions adapted to local realities.
