Abstract
Objective: Evaluate the applicability of SISS-Geo in the monitoring of animals reservoirs of the Yellow Fever Virus (VFA) in Brazil and relate to confirmed cases in the South and Southeast regions. Methods: This is an ecological, cross-sectional, and descriptive study of the analysis of vaccination coverage for yellow fever (AF) and SISS-Geo for records of wild animals. Results: An expansion was observed from 2016 to Southeast and South, areas without vaccine recommendation, with 2,227 cases confirmed, with lethality rate ranging from 19% to 100%, characterizing the current outbreak scenario in some states. Regarding the monitoring of epizootics, there is a correlation between the increase in cases and records of wild animals, being effective in controlling/detecting viral circulation. Conclusion: After data analysis, there is the absence of immunization, providing increased susceptibility of the population and dissemination of the disease. In addition, it reports the monitoring of SISS-Geo being effective in disease control, requiring a greater incentive to use this resource. Since this, it exposes the importance of constant monitoring of vaccination coverage, active investigation of wild animal records and cases of AF.
