Phylogenetic-based inference reveals distinct transmission dynamics of SARS-CoV-2 lineages Gamma and P.2 in Brazil.

The COVID-19 epidemic in Brazil experienced two major lineage replacements until mid-2021. The first was driven by lineage P.2, in late 2020, and the second by lineage Gamma, in early 2021.

Spread of Gamma (P.1) Sub-Lineages Carrying Spike Mutations Close to the Furin Cleavage Site and Deletions in the N-Terminal Domain Drives Ongoing Transmission of SARS-CoV-2 in Amazonas, Brazil.

The Amazonas was one of the most heavily affected Brazilian states by the COVID-19 epidemic. Despite a large number of infected people, particularly during the second wave associated with the spread of the Variant of Concern (VOC) Gamma (lineage P.1), SARS-CoV-2 continues to circulate in the Amazonas.

Intra-urban differences in rates of admissions for ambulatory care sensitive conditions in Brazil's Center-West region.

Admissions for ambulatory care sensitive conditions (ACSCs) represent a useful indicator of assess to and the effectiveness of primary health care. This article examined rates of admissions for ACSCs and the main causes of admissions in intra-urban areas of the municipality of Goiânia, capital of the State of Goiás. An ecological study was conducted to determine rates of admissions in Goiânia's seven health districts between 2008 and 2013 using data from Hospital Admission Authorization forms obtained from the municipality's Hospital Information System.
