At this point, it appears that some people have been infected with the bird flu, and some have died from it. So far, the evidence is that transmission of the bird flu from human to human is very limited. This is only slightly reassuring; the real concern is that the virus will change (e.g., mutate) to allow efficient transmission between humans.
