Do avian influenza viruses spread from birds to humans?
There is only one case documented where H5N1 is thought to have been transmitted directly from wild birds to people. However, there are approximately 200 human cases where poultry to human transmission of the virus is suspected. These human cases are a relatively small number compared with the huge number of poultry affected and the numerous associated opportunities for human exposure, especially in areas of Asia where backyard flocks are common. Please visit the Centers for Disease Control website (Exit DNR) for further information on avian influenza infection in humans.
