Highly pathogenic H5N1 avian influenza (HPAI H5N1) is primarily a bird disease that is particular to domestic poultry, but can also infect most other birds both domestic and wild, and to a lesser extent, mammals. It is one of many types of avian influenza viruses. The HPAI H5N1 virus that is causing high mortality in poultry and wild birds in other countries has been identified in Asia, Africa, India, and Europe, but to date has not been found in North America.
One of the most widely held speculations of the movement of the virus to North America is through wild migratory birds, particularly waterfowl and shorebirds in the Pacific Flyway. Department of Fish and Wildlife personnel are currently monitoring this and other diseases that could enter California via migratory birds.
