Phocine distemper virus

Phocine distemper virus (PDV) is a paramyxovirus of the genus Morbillivirus that is pathogenic for pinniped species, particularly seals. Clinical signs include laboured breathing, fever and nervous symptoms.

PDV was first identified in 1988 as the cause of death of 18,000 harbor seals (Phoca vitulina) and 300 grey seals (Halichoerus grypus) along the northern European coast.
