First description of a mobatvirus (Hantaviridae) in the Amazon region.

From 1988-2023, Pará accounted for the highest proportion of deforestation among all states in the Brazilian Amazon. Specifically, 57.20 % of the territory in the Santa Bárbara municipality was deforested as of 2023.

Phylogenetic analysis of rabies surveillance samples from north and northeast Brazil.

Viruses of the genus are classified into several genotypes (GT1 to GT7), of which only GT1 (classic rabies virus-RABV) has a cosmopolitan distribution and circulates in Brazil. GT1 is subdivided into several antigenic variants (AgV) maintained in independent cycles with a narrow host range and distinct geographic distributions, namely, AgV1 and AgV2 found in dogs, AgV3 in the vampire bats , and AgV4 and AgV6 in bats non-hematophagous and , a common variant of marmoset (), and crab-eating fox (). In this study, we performed phylogenetic analysis to identify at the antigenic variant level; six RABV genomes derived from the Rabies Surveillance in the north and northeast regions of Brazil.

The Importance of Entomo-Virological Investigation of Yellow Fever Virus to Strengthen Surveillance in Brazil.

The largest outbreak of sylvatic yellow fever virus (YFV) in eight decades was recorded in Brazil between 2016-2018. Besides human and NHP surveillance, the entomo-virological approach is considered as a complementary tool. For this study, a total of 2904 mosquitoes of the , and genera were collected from six Brazilian states (Bahia, Goiás, Mato Grosso, Minas Gerais, Pará, and Tocantins) and grouped into 246 pools, which were tested for YFV using RT-qPCR.
