Bird Flu: Understanding the Threat and Preventing its Spread Bird flu, also known as avian influenza, is a contagious viral infection that can infect both domesticated birds like chickens, turkeys, ducks and geese as well as wild birds. The virus occurs naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species. There are various strains of bird flu virus but the one of major concern is called highly pathogenic avian influenza (HPAI) type A viruses. These strains are highly contagious among bird populations and can cause severe disease that spreads rapidly resulting in high mortality rates sometimes affecting as much as 90-100% of infected flocks. The H5N1 virus is one such strain that has caused large scale epidemics and pandemics among poultry since the late 1990s.
