The clinical picture includes an acute pulmonary form manifested by dyspnea, cough and profuse nasal discharge, and a subacute, cardiac form in which the principal signs are edema of the head and internally, oral petechiation and esophageal paralysis. The mortality rate is very high.

African swine fever
a peracute, highly contagious, highly fatal disease of pigs caused by African swine fever virus, previously a member of the family Iridoviridae, now the only member of the genus Asfivirus. The virus is carried by wart hogs in which it produces no disease and is transmitted to European pigs via the tick Ornithodoros moubata porcinus. The disease was originally confined to southern Africa, but is now enzootic in most countries in sub-Saharan Africa and has spread on occasion to Europe, including Spain, Portugal and Belgium, and also to Cuba and the Dominican Republic.
Currently the disease is eradicated from South America and the Caribbean countries but remains on the Iberian peninsula and Sardinia. The disease resembles classical swine fever (hog cholera). Clinically there is high fever, severe depression, purple skin discoloration, incoordination and posterior paresis. Death occurs about 2 days after the first signs of illness. In recent times the proportion of outbreaks which have been mild in severity has increased markedly.
