Summary: The aim of this study was to investigate whether forest areas influenced
epizootic events in white-headed marmosets (Callithrix geoffroyi) in the urban
environment during a yelow fever outbreak in Espírito Santo. To test the hypothesis that environmental features, such as the presence and size of forest fragments near built-up areas, may affect epizootic events on the species, we performed a Poisson Regression and a Microhabitat Classification. The Poisson Regression was based on the count of epizootics events in grids of 1 km² and 9 km² and the analysis of its correlation with the size of the built-up area and the forest area within each cell of the grids. Micro-habitat classification was made by measuring the distance from each epizootic point to the nearest forest fragment, and by observing and categorizing the area within the 100-m buffer around each point, considering categories A, wooded urban area, and B, edge of a forest fragment. Of the events analyzed, 43.90% were in areas classified as forest edge (B) and 100% of them were in wooded areas. The average distance between the reporting points and the nearest forest fragment was
140 m. In Poisson Regression, the two predictor variables showed a positive
correlation with the notification of epizootics. From this, a possible new pattern in yellow fever transmission in urban areas was discussed.
