Quick Summary

Asfivirus is a genus of viruses within the family Asfarviridae. The only known member of this genus is the African swine fever virus. These viruses have enveloped particles, approximately 175–215 nm in diameter, containing linear double-stranded DNA within an icosahedral capsid. The African swine fever virus is thought to cycle between soft ticks and pigs, and it is primarily found in sub-Saharan Africa. It is important to note that African swine fever is distinct from African horse sickness, which affects equids and is caused by a different type of virus.12

…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. An icosahedral capsid (the protein shell surrounding the viral nucleic acids) contains linear double-stranded DNA.
