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.
