Abstract
At the end of 2016, Brazil experienced an unprecedented yellow fever (YF) outbreak. Clinical, molecular and ecological aspects of human and non-human primate (NHP) samples collected at the beginning of the outbreak are described in this study. Spatial distribution analyses demonstrated a strong overlap between human and NHP cases. Through molecular analyses, we showed that the outbreak had a sylvatic origin, caused by the South American genotype 1 YFV, which has already been shown to circulate in Brazil. As expected, the clusters of cases were identified in regions with a low vaccination coverage. Our findings highlight the importance of the synchronization of animal surveillance and health services to identify emerging YF cases, thereby promoting a better response to the vulnerable population.
