- Abstract
Objective: This study aimed to investigate the relationship between the occurrence of yellow fever - YF and the climate and environment during the epidemic-epizootic process in the Brazilian Southeast region from 2016 to 2018. Methods: the methodology considered four approaches: a spatial analysis of the epidemiological situation; detection of clusters of human cases and spatial distribution of epizootics in clusters; identification of environmental and climatic factors; and correlation of the relative risk of the clusters with the associated factors. Results: Most positive cases occurred in Minas Gerais and São Paulo. Clusters were detected in the years 2017 and 2018. The study period had the highest temperature values and the lowest precipitation compared to the 20-year climatological period of analysis. Seasonality marks the temporal pattern of the disease, where most cases occur between December and May. In addition, outbreaks occur with irregular periodicity when the virus finds favorable conditions for transmission. The constant transformation was observed in geographic space, where land use and land cover have the highest percentage linked to rural areas, followed by forest areas. A correlation between the relative risk of clusters and environmental and climatic factors was confirmed. Conclusion: The correlation of climatic and environmental factors and the presence of vectors and non-human primates-PNHs generated a vulnerability scenario for the Southeast region. Public health plans for vaccinating the population and controlling urban vectors should be evaluated to prevent the re-emergence of urban YF.
