ICTV virus taxonomy profile: Arteriviridae 2021

Abstract

The family Arteriviridae comprises enveloped RNA viruses with a linear, positive-sense genome of approximately 12.7 to 15.7kb. The spherical, pleomorphic virions have a median diameter of 50-74nm and include eight to eleven viral proteins. Arteriviruses infect nonhuman mammals in a vector-independent manner. Infections are often persistent and can either be asymptomatic or produce overt disease. Some arteriviruses are important veterinary pathogens while others infect particular species of wild rodents or African nonhuman primates. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Arteriviridae, which is available at ictv.global/report/arteriviridae.
