Most of the people who get bird flu have had close contact with infected birds or with surfaces that have been contaminated by the birds' saliva, mucous, or droppings. It is also possible to get it by breathing in droplets or dust that contain the virus. Rarely, the virus has spread from one person to another.

How does bird flu spread in humans?

The disease is transmitted to humans through contact with infected bird feces, nasal secretions, or secretions from the mouth or eyes. Consuming properly cooked poultry or eggs from infected birds doesn't transmit the bird flu, but eggs should never be served runny.

Can bird flu spread through air?

The disease is transmitted via contact with an infected bird's feces, or secretions from its nose, mouth or eyes. Open-air markets, where eggs and birds are sold in crowded and unsanitary conditions, are hotbeds of infection and can spread the disease into the wider community.
