Description
Avian flu H5N1 is a highly contagious, highly pathogenic Type A influenza virus
that can affect many species of birds, including pet birds. It may affect the
respiratory, digestive and/or nervous systems.
Transmission to birds can be by a variety of routes,
including :
- Direct contact with
secretions from infected birds, especially faeces
- Contaminated
feed, water, equipment and clothing
Treatment
There is no satisfactory treatment for
this disease, and infected birds should be culled and disposed of using
effective biosecurity measures to prevent cross-contamination or transmission to
other birds, or human handlers.
There
is a vaccine available against the H5 avian flu strain, (Nobilis Influenza -
Intervet), which also provides protection against H7 and H9 strains, but
use of the vaccine is strictly controlled by Government Regulatory Authorities.
The possibility of a carrier state presents problems for other birds that may come into
contact with an infected individual, and this may also result in spread of the
disease across Continents through migratory wild birds.
