The genome consists of a bi-segmented linear, double-stranded RNA. The segments are distributed among two particle types of the RNA. The first segment is about 6350-7000 nucleotides in length; the second, about 5630-6500 nucleotides in length [1].
Virions consist of a non-enveloped rod-shaped capsid, having a helical symmetry of 120-360 nm in length, and a width of 18-30 nm.
