African swine fever virus African swine fever virus African swine fever virus (ASFV) is the causative agent of African swine fever (ASF). The virus causes a haemorrhagic fever with high mortality rates in pigs, but persistently infects its natural hosts, warthogs, bushpigs, and soft ticks of the genus "Ornithodoros", with no disease signs. ASFV is a large, double-stranded DNA virus which replicates in the cytoplasm of infected cells. ASFV infects domestic pigs, warthogs, and bushpigs, as well as soft ticks ("Ornithodoros"), which likely act as a vector. ASFV is the only known virus with a double-stranded DNA genome transmitted by arthropods. The virus causes
