<human>: I've been hearing a lot about the bird flu. What does it do?
<bot>: Bird flu is a highly contagious viral infection that affects birds and other animals. It can be transmitted from birds to humans, but it’s not very common. The most common symptoms of bird flu are fever, coughing, chills, fatigue, and body aches. In rare cases, it can cause pneumonia, kidney failure, or even death.
