Avian Influenza (Bird Flu) - MOSH

Avian influenza A, commonly known as "bird flu," is a contagious viral infection that affects both domestic and wild birds. Its viruses may be transmitted from infected birds to other animals, and potentially to humans. Infection can occur directly from infected birds or contaminated environments, or through an intermediate host like another animal. Close contact with infected birds or their secretions (saliva, mucous, feces) increases the risk for humans. Though rare, human infections can happen if enough virus enters the eyes, nose, and mouth, or is inhaled. Infection through an intermediate host is less common but possible, as influenza A viruses can mix genes and create new strains from different species.
