Asfarviridae is a family of viruses, the best-studied of which is African swine fever virus, which are double-stranded DNA viruses. Taxonomy. There is only one species under Asfarviridae in ICTV 2022: Genus Asfivirus. Species African swine fever virus; But, there may be more viruses: Abalone asfarvirus
African swine fever virus (ASFV) is a large, double-stranded DNA virus in the Asfarviridae family. It is the causative agent of African swine fever (ASF). The virus causes a hemorrhagic fever with high mortality rates in domestic pigs; some isolates can cause death of animals as quickly as a week after infection.
The family Asfarviridae includes the single species African swine fever virus, isolates of which have linear dsDNA genomes of 170–194 kbp (Table 1. Asfaviridae). Virions have an internal core, an internal lipid layer, an icosahedral capsid and an outer lipid envelope.
- Description
asfarvirus, any virus belonging to the family Asfarviridae. This family consists of one genus, Asfivirus, which contains the African swine fever virus. Asfarviruses have enveloped virions (virus particles) that are approximately 175–215 nm (1 nm = 10 −9 metre) in diameter.

Asfarviridae is a family of viruses that primarily infects swine, resulting in an onset of African swine fever. There is a single genus in this family: Asfivirus. The name of this family and genus are derived from the acronym: African swine fever and related viruses. Only a single species has been described to date for this genus.
The Asfarviridae family consists of a single genus Asfivirus which contains one member: African swine fever virus (ASFV). The virus contains a double-stranded DNA genome varying in length between 170 and 193 kbp with terminal cross-links and inverted terminal repeats.
