Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
  • Source of infection might be migratory wild birds.
Epidemiological comments African penguins (Jackass penguins) at a conservation site (breeding site) on the Halifax Island, which is a small rocky island about 100 m (330 ft) from the mainland, near Lüderitz, showed signs suspected to be of highly pathogenic avian influenza. These were neurological signs (head tilting, twitching, incoordination), corneal opacity and lethargic/comatose behaviour. The disease is currently limited to African penguins only; no other wild birds are affected at the Halifax Island.
