There is still limited data reported on virus diversity in South American bats. In this study, the authors report a divergent betacoronavirus with a functional furin cleavage site in South American ba...

A wild migratory bird in Western Australia has returned a suspected positive result for avian influenza, which has devastated populations of seabirds, seals and other animals across the world.

A method using subtree pruning and regrafting-based tree assessment (SPRTA), which considers evolutionary relationships between lineages, enhances interpretability of phylogenetic analyses such as those of SARS-CoV-2 variants.

Bats are natural reservoirs for a wide range of RNA viruses. Members of the genus Betacoronavirus, including Severe Acute Respiratory Syndrome virus 2 (SARS-CoV-2) and Middle East Respiratory Syndrome...

Phylogenetic studies examining the origins, emergence, and spread of viruses have arguably been one of the most active and successful areas of evolutionary biology and form the bedrock of the flourishing field of genomic epidemiology. This, in part, reflects the ability of viruses, particularly those with RNA genomes, to evolve at rates much greater than their cellular counterparts (1). The rapid rate at which viruses evolve and accumulate mutations enables evolutionary signals to be identified through comparative genomics at short timescales relevant for outbreak investigation and response. The integration of phylogenetics and epidemiology, known as phylodynamics, has become a vital tool in response to numerous viral outbreaks, epidemics, and pandemics, including Ebola (2), Zika (3), and, more recently, COVID-19 (4) and mpox (5).

Author summary The discovery of brine shrimp virga-like virus 1 (BSVV1) challenges the conventional view that positive- and negative-sense RNA viruses are evolutionarily independent. Through genomic a...
