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.
Virus names, the choice of exemplar isolates, and virus abbreviations, are not official ICTV designations

Viruses assigned to the genus Higrevirus form a monophyletic group based on a well-supported maximum likelihood tree inferred from the RNA-directed RNA polymerase (RdRP). Higrevirus genomes are split into three segments and encode a novel specialized transport module called binary movement block (BMB). Hibiscus green spot virus 2 (HGSV2, Higrevirus waimanalo) causes non-systemic infections and is transmitted by mites of the genus Brevipalpus.
Viruses assigned to the genus Cilevirus form a monophyletic group based on a well-supported maximum likelihood tree inferred from the RNA-directed RNA polymerase (RdRP). Cilevirus genomes are split into two segments. Viruses in the genus cause non-systemic diseases and are persistently transmitted by mites of the genus Brevipalpus.
