Avian influenza (AI) is caused by those influenza viruses that mainly affect birds and poultry, such as chickens or ducks. These AI viruses are distinct from human seasonal influenza viruses. Since the AI viruses does not commonly infect human, there is little or no immune protection against them in the human population. People mainly become infected with AI through direct contact with infected birds and poultry (live or dead), their droppings or contaminated environments.
