Avian influenza is a disease that primarily affects which type of animal?

Avian influenza, commonly known as bird flu, is a disease primarily affecting birds, particularly domestic poultry like chickens and turkeys, as well as various wild bird species. The virus is a type of influenza virus that is adapted to avian hosts and primarily spreads among birds. Understanding this specificity is critical, as the disease can have significant implications for avian populations, agriculture, and even human health in cases where zoonotic transmission occurs.

While mammals, fish, and reptiles are important in their respective ecosystems and can be affected by various diseases, avian influenza is designated as a disease of birds due to its viral structure and mode of transmission. This specialization helps in developing appropriate control and prevention strategies focused on avian species, which is essential in managing outbreaks and protecting both wildlife and livestock.
