Dispersion patterns of SARS-CoV-2 variants Gamma, Lambda and Mu in Latin America and the Caribbean

Genomic surveillance has been important for tracking the evolution and spread of SARS-CoV-2. Here, the authors analyse ~300,000 SARS-CoV-2 genomes from two years of sequencing in the Latin America and Caribbean regions and describe the emergence and spread of different lineages over time.

Human outbreaks of a novel reassortant Oropouche virus in the Brazilian Amazon region

Genomic and epidemiologic analyses revealed that a novel reassortant viral lineage of the Oropouche virus, which has been circulating in the western Amazon region of Brazil for about a decade, is associated with the recent human outbreaks between 2022 and 2024.

COVID-19 in Amazonas, Brazil, was driven by the persistence of endemic lineages and P.1 emergence

Analysis of circulating SARS-CoV-2 viruses during the first and second waves of COVID-19 in Amazonas, Brazil, shows successive lineage replacements led to predominance of the variant of concern P.1 and are associated with variable levels of social distancing.

Comparative epidemic expansion of SARS-CoV-2 variants Delta and Omicron in the Brazilian State of Amazonas

The Amazonas region has been the most heavily affected by COVID-19 in Brazil. In this study, the authors conduct phylodynamic analyses to assess SARS-CoV-2 lineage replacement dynamics in the region and infer the impact of population immunity on the spread and severity of the Delta and Omicron variants.

SARS-CoV-2 evolution during treatment of chronic infection

Chronic infection with SARS-CoV-2 leads to the emergence of viral variants that show reduced susceptibility to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma.

Sensitivity of SARS-CoV-2 B.1.1.7 to mRNA vaccine-elicited antibodies

Sera from vaccinated individuals and some monoclonal antibodies show a modest reduction in neutralizing activity against the B.1.1.7 variant of SARS-CoV-2; but the E484K substitution leads to a considerable loss of neutralizing activity.
