Monodnaviria classification updateAugust 2026

The taxonomy has been updated for the realm of monodnaviria. It has been split in three monophyltic realms: one with eukaryotic viruses Floreoviria, one with bacterial viruses Efunaviria, and one with archaeal viruses Volvereviria. Moreover the Pleomoviria realm assemble all archaeal viruses with a common pleomorphic envelope.

Polyprotein Cleavage PredictionAugust 2026

The Polyprotein Cleavage Prediction page provides matured products in Fasta for virus families infecting humans and encoding polyproteins. It has been has been enriched with Togaviridae, Picornaviridae and Caliciviridae virus families

Ebolavirus resourceJune 2026

The Ebolavirus features a detailed virus fact sheet, dedicated pages on viral proteins, as well as virus replication cycle. Moreover it provides links to epidemiology Nextstrain resources, and sequence shared by Pathoplexus.

Andes virus resourceJune 2026

The Andes virus resource brings together extensive information, including data specifically related to the 2026 cruise ship outbreak of Andes virus (a hantavirus). It features a detailed virus fact sheet, dedicated pages on viral glycoproteins, as well as references and variant information. The hantavirus virion illustration has also been updated and is now available.
