Supplement

Goose viral hepatitis is a viral hepatitis affecting the goslings and Muscovy ducklings. It is highly contagious gastrointestinal disease although it is not zoonotic. There were no reports of the disease affecting humans and other avian or mammalian species.1 It is caused by a parvovirus that belongs to a group of DNA viruses belonging to the Parvoviridae. There are two types of viruses causing the disease, i.e. goose parvovirus and muscovy duck parvovirus.

The viral causative agent is shed in the feces and therefore may be transmitted horizontally (i.e. via direct faecal-oral route). For instance, birds acquire the virus from ingesting food or water contaminated by the virus in the fecal matter of diseased birds. Vertical transmission (e.g. young birds in the hatchery being infected via infected eggs) is also possible.1 The disease is age-specific. It occurs in birds under seven- to ten-day old. Symptoms during the acute stage include anorexia, polydipsia, nasal and ocular discharge, head shaking, swollen uropygial glands and eyelids, and profuse diarrhea.1
