Newly discovered viruses in dead and dying farmed Chinook salmon are widely distributed in threatened wild Chinook and sockeye salmon populations.

A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.

A global map of environmental suitability for Zika virus and the estimated population living at potential risk can help refine public health guidelines, travel advisories and intervention strategies at a crucial time in the global emergence of this arbovirus.

The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.

Data-driven methods predict over 35 mosquitoes are potential vectors of Zika virus, suggesting a larger geographic area and a greater human population is at risk of infection.

From public microbial genomes, VirSorter revealed 12,498 viral genome sequences that expand the map of the global virosphere and whose analyses improve understanding of viral taxonomy, evolution and virus-host interactions.

Single-cell amplified genome sequencing uncovers virus-host interactions in uncultivated sulfur-oxidizing bacteria with relevance to coupled biogeochemical cycling in marine oxygen minimum zones.

The Dengue virus contains discretely folded RNA structures that confer the ability to resist a powerful host cell enzyme and produce a disease-inducing noncoding RNA.

Infection experiments in ferrets reveal swine influenza viruses need their hemagglutinin antigen to become stabilized for transmissibility, adding a new property to consider when triaging field isolates for pandemic potential.

The first lethal Junín virus challenge model in immunocompetent mice provides insight into New World mammarenavirus pathogenesis and will serve as a model for the development of much-needed therapeutic interventions.
