TL;DR: Results of phylogenetic and molecular clock analyses show a single introduction of ZikV into the Americas, which is estimated to have occurred between May and December 2013, more than 12 months before the detection of ZIKV in Brazil.

TL;DR: The modern-lineage caused all major YFV outbreaks detected in non-endemic South American regions since 2000, including the 2017 Brazilian outbreak, and its dissemination was coupled to the accumulation of several amino acid substitutions particularly within non-structural viral proteins.

TL;DR: In this article, the authors used the funding support from CGLab/MoH======676 (General Laboratories Coordination of Brazilian Ministry of Health), CVSLR/FIOCRUZ (Coordination of Health Surveillance and Reference Laboratories of Oswaldo Cruz Foundation), CNPq======COVID-19 MCTI 402457/2020-0.

TL;DR: The complete genome of 12 YFV samples from mosquitoes, humans and non-human primates from the Brazilian 2017 epidemic is described to confirm that viral strains associated with the most severe YF epidemic in South America in the last 70 years display unique amino acid substitutions that are mainly located in highly conserved positions in non-structural proteins.

TL;DR: The genetic diversity of SARS-CoV-2 during the early phase (late February to late April) of the epidemic in Brazil is investigated to support occasional exportations of this Brazilian B. 1.1.1 lineage to neighboring South American countries and to more distant countries before the implementation of international air travels restrictions in Brazil.
