This article reports changes to the virus taxonomy ratified by the (ICTV) in March, 2022. The entire ICTV was invited to vote on 174 taxonomic proposals approved by the ICTV Executive Committee at its annual meeting in July 2021. All proposals were ratified by an absolute majority of the ICTV members.
The new 2021 ICTV taxonomy is now available online at https://ictv.global/taxonomy. The new Master Species List #37 is available for download as an Excel Spreadsheet.

Welcome to the new ICTV web site. This new web site will modernize the ICTV data access infrastructure to provide a stable, responsive, scalable information technology platform based on modern, cloud- based, open-source systems. This infrastructure will provide an easy-to-use web-based platform supporting significant enhancements to our ability to provide information and tools on virus classification and taxonomy.
Similar to comovirins, cheraviruses, sadwaviruses, stralariviruses, and torradoviruses, the genome of merseviruses is bipartite. However, the RNA1 of merseviruses codes for a polyprotein that is proteolytically cleaved into six predicted proteins instead of the more conventional five proteins. The sixth protein located at the N-terminus of the polyprotein encoded by RNA1 codes a Ham1 domain with predicted inosine triphosphate pyrophosphatase (ITPase) activities.
Virus names, the choice of exemplar isolates, and virus abbreviations, are not official ICTV designations
