→Clinical Signs
In the acute form, animals are almost always pyrexic. In piglets under 12 weeks old the fever may exceed 40°, but in adults temperatures may be no higher than 39.5°. Lethargy, conjunctivitis, lymphomegaly may be seen, as well as respiratory signs and diarrhoea. Neurological signs such as gait abnormalities, incoordination and convulsions are also common. The most telling sign of classical swine fever is haemorrhage of the skin. These arise in the second or third week post-infection on the ear, tail, abdomen and medial aspect of the limbs and persist until death.
