Avian (bird) Flu is caused by influenza A viruses that occur naturally among birds. There are different subtypes of these viruses because of changes in certain proteins on the surface of the influenza A virus and the way the proteins combine.
The risk from avian influenza is generally low to most people, because the viruses do not usually infect humans. Most cases of infection in humans have resulted from contact with infected poultry or contaminated surfaces.
