To the general public, the bird flu should not be an issue of concern.
The key to the bird flu is the fact that it's not currently transmissible between humans. The reason is that the bird flu lacks the various components necessary for this process. In order to obtain those components, it must mutate. All strains of the flu actually mutate quite frequently. That is why a new flu vaccine must be developed every year, and that's also why the flu vaccine doesn't always work-----in order to develop it, scientists must make a very educated guess about what the upcoming year's strain will look like. However, even though the flu mutates all the time, a few rare occurrences must take place in order to have human-to-human transmission. First, a human must get infected with the bird flu from an infected animal. That human MUST be infected with a normal, human flu AT THE SAME TIME, or catch the human flu while he/she is infected with the bird flu. THEN, if that happens, the two flu viruses must swap parts---"mutate," in a sense. The exact part that allows human-to-human trasmission must combine with the exact parts that make the bird flu so deadly. Finally, IF all that occurs, then the infected person must trasmit the new, mutated version to another person.
There are a lot of "ifs." All those ifs are very possible; major outbreaks resulting from similar events have happened many times in the past. However, all of this isn't really an issue that the general public needs to worry about. It's an issue that needs to be dealt with by 1) scientists, to develop vaccines, and 2) governments, to develop plans to distribute vaccines, to quarantine, etc., should an outbreak occur. For the general public, there's nothing to do and there's no need whatsoever to worry about it. If for some reason you're seriously concerned, the best you can do is pester your local public officials to fund research & develop plans. The bird flu does not need to be on the news every other day. Your dog may very well have gone to puppy heaven well before an outbreak ever occurs, if it ever does!
