What is Bird Flu / Avian Influenza?
Avian Influenza is a virus that normally only infects birds, most notably ducks and chickens. There are numerous strains of the virus in which an infected bird may show few symptoms to others where the virus will rapidly overwhelm a birds immune system and prove fatal in the majority of cases due to acute respiratory failure. Once a single bird has become infected with a highly pathogenic strain of the influenza virus it can quickly spread to a whole flock with typically dire consequences. Most strains of bird flu pose absolutely no threat to humans.
