Diagnosis: Notifiable disease in the UK. Diagnosis of CSFV by virus detection in tissues, particularly the tonsil and pancreas, (immunoflourescence) or antigen detection (ELISA or AGID). VN is still used to distinguish SFV and BVDV. For chronic disease CVL have developed a one-tube RT-PCR which avoids the chance of amplified product contaminating the lab.

In 1987 border disease was the cause of a swine-fever-like illness.
