Central Public Health Laboratory of Bahia (SVS/MS) that coordinated surveillance and performed
sample collection and clinical records, to Flaviviruses Reference Laboratory of
Oswaldo Cruz Institute from Rio de Janeiro, for performing YFV diagnostics and Epidemiological
Surveillance Department of Bahia state for management of surveillance data. We also
thank Coordenac¸ão de Aperfeic¸oamento de Pessoal de Nı´vel Superior (CAPES) for national
and abroad scholarships and the Department of Surveillance of Transmissible Diseases—Brazilian
Ministry of Health (DEVIT/MS) for sampling authorization and laboratory access
support. Yellow fever virus (YFV) causes a clinical syndrome of acute hemorrhagic hepatitis. YFV
transmission involves non-human primates (NHP), mosquitoes and humans. By late 2016,
Brazil experienced the largest YFV outbreak of the last 100 years, with 2050 human confirmed
cases, with 681 cases ending in death and 764 confirmed epizootic cases in NHP.
Among affected areas, Bahia state in Northeastern was the only region with no autochthonous
human cases. By using next generation sequence approach, we investigated the
molecular epidemiology of YFV in NHP in Bahia and discuss what factors might have prevented
human cases. We investigated 47 YFV positive tissue samples from NHP cases to
generate 8 novel YFV genomes. ML phylogenetic tree reconstructions and automated subtyping
tools placed the newly generated genomes within the South American genotype I (SA
I). Our analysis revealed that the YFV genomes from Bahia formed two distinct well-supported phylogenetic clusters that emerged most likely of an introduction from Minas
Gerais and Espı´rito Santo states. Vegetation coverage analysis performed shows predominantly
low to medium vegetation coverage in Bahia state. Together, our findings support the
hypothesis of two independent YFV SA-I introductions. We also highlighted the effectiveness
of the actions taken by epidemiological surveillance team of the state to prevented
human cases.
