Orthonairovirus
Sign in to saveOrthonairovirus is a genus of viruses in the family Nairoviridae of the order Hareavirales which includes viruses with circular, negative-sense single stranded RNA. The name is derived from the Nairobi sheep disease which affects the gastrointestinal tracts of sheep and goats. All viruses in this genus are tick-borne viruses with human or other vertebrate hosts.

Orthonairovirus is a genus of viruses in the family Nairoviridae of the order Hareavirales which includes viruses with circular, negative-sense single stranded RNA. The name is derived from the Nairobi sheep disease which affects the gastrointestinal tracts of sheep and goats. All viruses in this genus are tick-borne viruses with human or other vertebrate hosts.
== Structure == The virions for viruses in this genus have a spherical shape. They range in size from about 80–120 nm in diameter, with 50% of their weight attributed to proteins and 20–30% of their weight attributed to lipids. The ribonucleocapsid is filamentous, having a length of about 200-300 nm and a width of about 2–2.5 nm. These nucleocapsids are surrounded by a single envelope that has projections made of glycoproteins protruding from its surface. These projections evenly cover the surface of the virion, and are about 5–10 nm long. They aid in attachment to the host receptor in replication.
