Duck viral enteritis is caused by a '''[[Herpesviridae|herpesvirus]]''' which can also infect geese and swans. The disease is '''acute and highly infectious''', causing high morbidity and mortality.

In young birds, these pathological changes are often associated with the '''[[Regional Lymphoid Tissue - Anatomy & Physiology#Structure|gut-associated lymphoid tissue (GALT)]]'''. Organs often also demonstrate degenerative and necrotic changes and the gizzard and intestines are commonly '''filled with blood.'''

'''Intranuclear inclusion bodies''' can be detected via electron microscopy.

'''Intranuclear inclusion bodies''' can be detected via electron microscopy. PCR can be used to detect infection.

Serology can indicate previous exposure but is of limited use in active outbreaks.
