-The fever of ephemeral fever is generally biphasic, sometimes triphasic, with peaks of 40-41.5° C spaced 12-18 hours apart
-Accelerated heart and respiratory rates, anorexia, ruminal atony, depression, serous or mucoid nasal and ocular discharges, salivation, muscle twitching or waves of shivering, a generalized stiffness or a shifting lameness.
-There may be submandibular edema or patchy edema elsewhere on the head. -Many animals become recumbent for 12-24 hours but are able to rise if sufficiently stimulated. Others are completely unable to rise and remain in sternal recumbency for hours or days with the head turned to the flank, or in lateral recumbency with or without loss of most reflexes. Recovery begins 1-2 days after the overt clinical signs are first noticed and is usually complete and without sequelae in a further 1- 2 days after the overt clinical signs are first noticed. The early signs of improvement develop in a few hours after fever disappears in most cattle
