Avian influenza viruses have evolved to infect birds, but the current H5N1 outbreak is also infecting a wide range of mammals. This suggests that it could mutate into forms that threaten humans.

While a small proportion of people have become ill while in contact with infected birds, there is no evidence it has spread from human to human.
Wild birds like pelicans and ducks are getting infected with – and dying from – a new strain of avian influenza and have spread it to farm animals around the world.

A scientific question fascinates experts : under which conditions can bird flu virus be transmitted to humans by aerial particles, and what will be the consequences for those who aren’t immune?
