  • Here, the authors present results of the ZiBRA-2 project (https://www.zibra2project.org) which is an arbovirus surveillance project, across the Midwest of Brazil using a mobile genomics laboratory, combined with a genomic surveillance training program that targeted post-graduate students, laboratory technicians, and health practitioners in universities and laboratories.

  • Chikungunya virus is endemic in Brazil and cases have been rapidly increasing in recent years. Here, the authors describe the expansion of a genomic surveillance program across the country allowing them to characterise the emergence and dispersal of two distinct subclades mainly seeded from the north eastern region.

  • Andrade, Adelino, Fonseca et al. used phylogenetic, phylogeographic, and temporal approaches to track yellow fever viral transmission across forestry, rural, and urban areas of Brazil. All genomes belong to the South American lineage, with one Amazon cluster showing hidden persistence and another in the southeast indicating reintroduction and sustained transmission.

  • Rodrigues and Queiroz et al. report the discovery of Naiavirus, the largest enveloped virus, isolated from a Brazil biome. With an oval capsid and flexible tail, its giant genome holds many novel genes, underscoring the value of viral isolation studies.

  • The 501Y.V2 variant of SARS-CoV-2 in South Africa became dominant over other variants within weeks of its emergence, suggesting that this variant is linked to increased transmissibility or immune escape.

  • Interrogation of 1,365 near whole-genome sequences of SARS-CoV-2 variants isolated in South Africa during the first 6 months of the global pandemic reveals three major monophyletic lineages responsible for more than half of the infections in the country and underscores the value of integrating genomic surveillance methods to inform the national pandemic response.

  • Cross-neutralization assays of early variants and the 501Y.V2 variant of SARS-CoV-2 show that plasma from individuals infected with 501Y.V2 effectively neutralizes all variants, indicating that a vaccine that targets 501Y.V2 may also be effective against other SARS-CoV-2 variants.

  • Giovanetti et al. examine SARS-CoV-2 transmission dynamics in Italy using phylodynamic analysis of viral genetic and epidemiological data. They present evidence to suggest that the efficacy of public health interventions is limited by the size and structure of epidemic reservoirs, which may influence vaccination programmes.
