Orbivirus

The genus Orbivirus is a member of the Reoviridae family, in the subfamily Sedoreovirinae. Unlike the other reoviruses, orbiviruses are arboviruses. This genus currently contains 22 species (including the type species Bluetongue virus) and at least 130 different serotypes. Orbiviruses can infect and replicate within a wide range of arthropod and vertebrate hosts. Orbiviruses are named after their characteristic doughnut shaped capsomers (Orbi in Latin means ring).
