The _Highly Pathogenic Avian Influenza_ (HPAI) H5N1 virus, commonly referred to as bird flu, is deadly to poultry and can be transmissible to humans. While the risk to humans is considered low, infection can cause severe respiratory illness and even death.
The virus originates in wild birds and can spread to poultry through contact with infected birds or their bodily fluids, often via contaminated feed or water sources. Once in a flock, the virus can spread rapidly, causing many birds to become sick and die.
Outbreaks of bird flu have occurred in several parts of the world, including the United States, Asia, Europe, and Africa. The most recent outbreak in the United States began in February 2022 and has affected both commercial and backyard flocks.
How Does Bird Flu Spread?
Bird flu is primarily spread among birds, but it can also spread from birds to humans through direct contact with an infected bird or its bodily fluids, including feces and saliva. Less common is transmission through contact with contaminated surfaces such as cages or equipment.
What Are the Symptoms of Bird Flu in Humans?
