We characterized 3 autochthonous dengue virus serotype cases and 1 imported case from 2 states in the North South Regions of Brazil, 15 years after Brazil's last outbreak involving this serotype. also identified a new Asian lineage recently introduced into Americas, raising concerns about future outbreaks.
ABSTRACT The Brazilian western Amazon region is currently experiencing its largest laboratory confirmed Oropouche virus (OROV) outbreak, with nearly 6,000 reported cases in the states of Amazonas (AM), Acre (AC), Rondônia (RO), and Roraima (RR), between August 2022 March 2024. Here, we sequenced analyzed 382 full-length OROV genomes from human samples collected 2024 all four states, aiming to trace origin genetic evolution leading current outbreak. Genomic analyses revealed that recent...
Abstract The SARS-CoV-2 variants of concern (VOCs) Delta and Omicron spread globally during mid late 2021, respectively. In this study, we compare the dissemination dynamics these VOCs in Amazonas state, one Brazil’s most heavily affected regions. We sequenced virus genome from 4128 patients collected between July 1st, January 31st, 2022, investigated viral using a phylodynamic approach. BA.1 displayed similar patterns phylogeographic but different epidemic dynamics. replacement Gamma by was...
Abstract Dengue virus serotype 2, genotype Cosmopolitan (DENV-2-GII), is one of the most widespread DENV strains globally. In USA, DENV-2 epidemics have been dominated by Asian-American (DENV-2-GIII), and first cases DENV-2-GII were only described in 2019, Peru, 2021 Brazil. To gain new information about circulation Brazil, we sequenced 237 confirmed sampled between March 2023 revealed that already present all geographic regions The phylogeographic analysis inferred was introduced at least...
Abstract In 2023, three autochthonous DENV-3 cases were detected in Roraima and one imported case Paraná, fifteen years after the last outbreak Brazil. Phylogenetic analyses confirmed all belonging to a new Asian lineage recently introduced Americas, raising concerns about future large dengue outbreaks this region.

ABSTRACT The SARS-CoV-2 variants of concern (VOCs) Delta and Omicron spread globally during mid late 2021, respectively, with variable impact according to the immune population landscape. In this study, we compare dissemination dynamics these VOCs in Amazonas state, one Brazil’s most heavily affected regions. We sequenced virus genome from 4,128 patients collected between July 1st, 2021 January 31st, 2022 investigated lineage replacement using a phylodynamic approach. displayed similar...
