Abstract

The family Totiviridae comprises viruses with nonsegmented dsRNA genomes and isometric virions. A new genus, Victorivirus, has been approved for this family, named from the specific epithet of Helminthosporium victoriae, host of the type species, Helminthosporium victoriae virus 190S. Distinguishing characteristics of the 11 viruses so far assigned to this genus include infection of filamentous fungi, an apparently coupled termination–reinitiation mechanism for translating the RNA-dependent RNA polymerase as a separate product from the upstream capsid protein, and sequence-based phylogenetic grouping in a distinct clade from other family members.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
