Sydney Reports First H5N1 Case, Authorities Urge Bird Flu Precautions
A dangerous bird sickness called H5N1 was found in a wild bird in Sydney.
The bird was a greater crested tern found in the Northern Beaches.
This is the first confirmed H5N1 case reported in Sydney.
Officials are asking people with pet birds or chickens to avoid contact with wild birds.
Dog owners should stop their dogs from chasing wild birds or eating dead animals.
The virus can make birds very sick and has killed millions of birds worldwide.
H5N1 has also infected some mammals, including people, but this report does not describe a human case in Sydney.
