Also known as three-day sickness
Bovine ephemeral fever (BEF) is a viral disease of cattle and buffalo. Typically, affected animals are only sick for a few days, giving rise to the common name of three-day sickness.
Clinically there is a sudden onset of fever (up to 41ºC), often returning to normal within 36 hours. Animals may stop eating and drinking and become depressed. Nasal discharge, drooling and watery eyes may be seen. Affected animals may shiver, become very stiff with a shifting lameness and are reluctant to move. Some animals, particularly the heavier ones, lie down and refuse to move. In the vast majority of cases the disease runs a short course, followed by rapid and complete recovery.
BEF is an example of an arbovirus because it is spread by biting insects. The most likely insects to transmit the virus in NSW are mosquitoes, such as Culex annulirostris but there may be other vectors that have not been identified.
The diagnosis of BEF is made on the presence of clinical signs in conjunction with PCR and/or serological testing.
