Bovine Ephemeral Fever is caused by an RNA virus – a [[Rhabdoviridae|rhabdovirus]]. Typically there is a sudden onset of fever with a sudden milk drop. It is transmitted rapidly with evident lameness, depression and often anorexia. Recovery is often rapid – 3 day fever. Morbidity can be up to 100% but mortality is low (1-2%). | Bovine Ephemeral Fever is caused by an RNA virus – a [[Rhabdoviridae|rhabdovirus]].
