Overview
Avian influenza, commonly known as bird flu, is a viral infection that affects birds. The disease is caused by influenza type A virus, which can lead to severe respiratory symptoms and high mortality rates in affected birds. While primarily a disease of birds, certain strains can infect humans, posing a significant zoonotic risk.
