ASFv: Genetic variation and evolution

African Swine Fever can lead to high levels of pig mortality. What, however, is known about the virus itself and its genetic origin? In total, 24 different genotypes have been described. Only genotypes I and II have spread to countries outside the African continent. African Swine Fever (ASF) is a highly contagious haemorrhagic disease that causes high mortality rates in swine production systems worldwide. The disease is caused by ASF virus (ASFv), and it was first reported in the 19th century
