In 2025, Brazil became the first country with a population exceeding 100 million to achieve validation of the elimination of mother-to-child transmission (MTCT) of HIV as a public health problem1.

Abstract It is challenging to assess SARS-CoV-2 viral kinetics amidst viral variant evolution and changes in population-level immunity. However, understanding the relationship between host factors and viral replication deepens our understanding of viral fitness. In CoVPN 5001, we enrolled N = 953 adults diagnosed with acute SARS-CoV-2 from July 2020 to July 2022 across 51 sites. We confirmed SARS-CoV-2 infection by RT-PCR and identified the variant via viral genome sequencing.
