Overt African swine fever (ASF) in its classical form is a peracute to acute, highly fatal disease of domestic pigs caused by a virus. It was originally confined to Africa by its natural hosts, namely argasid ticks and wild suids in which infection is inapparent. The disease is characterized by high fever, short course with skin congestion, cyanosis, prostration, and widespread haemorrhages in many organ systems, particularly the lymphoid tissues. Morbidity and mortality rates are almost 100 %. However, where the disease has become endemic in domestic pigs, mortality rates may be considerably reduced.
