The ICTV has collaborated with the EVORA project (European Viral Outbreak Response Alliance) to develop an application programming interface (API) that provides public programmatic access to the virus taxonomy through the transformation of the data into a virus taxonomy ontology and serving it through the EVORA Ontology Lookup Service (OLS) API. Documentation on how to access and use the API is available at https://evora-project.github.io/ictv-ontology/helpers/.

A new version of the Virus Metadata Resource (VMR) spreadsheet (VMR_MSL41.v1.20260729.xlsx) has been released that updates the virus exemplar records for MSL41, the 2025-2026 taxonomy and Master Species List. This new VMR version, released on July 29, 2026 (a previous release on July 21, 2026 contained several errors and should be discarded), can be downloaded from https://ictv.global/vmr/current.

A tribute to the life and work of Dr. Fred Murphy has been posted by the University of California, Davis Weill School of Veterinary Medicine. In addition to his extensive, pioneering work as a virologist, we would like to recognize Dr. Murphy for his efforts serving the ICTV. Fred first served as Vertebrate virus Subcommittee Chair from 1975 - 1981 and then as President from 1990 - 1996. He was also co-editor of the 6th (1995) ICTV Report on Virus Taxonomy.

New taxonomy proposals for 2026 can now be submitted. Templates for submitting proposals are available from https://ictv.global/taxonomy/templates. These 2026 templates MUST be used for all submissions. Please download all three files and read the Help file for detailed information on the submission process.

• The deadline for proposal submission to Subcommittee Chairs is September 15, 2026.

   

The new,  2025 ICTV taxonomy is now available through our taxonomy browser at https://ictv.global/taxonomy. This new version of Master Species List #41 is also available for download as an Excel Spreadsheet.
