What is bird flu? When birds, wild or domestic (家养的), catch a flu, they may pass the virus to each other. The most dangerous viruses can kill birds within hours.

People may catch the disease when handling birds or their waste. Scientists now worry that migratory wild birds might pass the disease to domestic birds. This could put more people in danger.

Since 2003, more than 120 people have caught bird flu in Southeast Asia. Half of them have died.

In the past several weeks, China has reported three outbreaks (爆发) of bird flu that have killed 3,800 chickens, ducks and geese.
