I've heard that there is a bird flu. What is the difference between a bird flu and the flu that affects humans?

Bird flu is a specific type of influenza virus that infects birds, but can also affect humans. Human flu is a general term for any strain of influenza virus that can infect humans. The two are similar in that they both cause symptoms such as fever, coughing, fatigue, and body aches. However, bird flu tends to be more severe and has been known to result in death in some cases.
