Okavirus
Virus classification
Group: Group IV ((+)ssRNA)
Order: Nidovirales
Family: Roniviridae
Genus: Okavirus
Type species
Gill-associated virus

Okavirus is a genus of virus. It is the only genus in the family (Roniviridae) in the order Nidovirales. Okaviruses infect crustaceans, mostly prawns.

The type species is Gill-associated virus.

The name is derived from the 'Oka' or lymphoid organ in which the viruses are commonly detected and in which pathology occurs during acute infections. Lymphoid organs are anatomical structures common to penaeid shrimp.

Taxonomy

Two species are recognised in this genus: Gill-associated virus and yellowhead virus. Both species were isolated from prawns.[1][2]
